Strange New Worlds. Explore an interactive gallery of some of the most intriguing and exotic planets discovered so far. Historic Timeline. A planetary tour through time. Kepler 's Final Survey Catalog. The Kepler mission was designed to detect transiting exoplanets and has succeeded in finding over candidates.

These candidates include approximately 50 terrestrial-sized worlds near to the habitable zone of their GKM dwarf stars shown in figure against the stellar temperature. However not all transit detections are created equal. False positives, such as background eclipsing binaries, can mimic the signal of a transiting planet. Additionally, at Kepler 's detection limit noise, either from the star or from the detector, can create signals that also mimic a transiting planet.

For the data release 25 Kepler catalog we simulated these false alarms and determined how often known false alarms are called candidates. When this reliability information is combined with our studies of catalog completeness, this catalog can be used to understand the occurrence rate of exoplanets, even for the small, temperate planet candidates found by Kepler.

I will discuss the automated methods we used to create and characterize this latest catalog, highlighting how we balanced the completeness and reliability of the long period candidates. While Kepler has been very successful at detecting transiting terrestrial-sized exoplanets, many of these detections are around stars that are too dim for successful follow-up work.

Future missions will pick up where Kepler left off and find small planets around some of the brightest and smallest stars.

The Kepler mission is designed to detect the transit of Earth-like planets around Sun-like stars by observing , stellar targets. Developing and testing the Kepler ground-segment processing system, in particular the data analysis pipeline, requires high-fidelity simulated data.

ETEM simulates the astrophysics of planetary transits and other phenomena, properties of the Kepler spacecraft and the format of the downlinked data.

Major challenges addressed by ETEM include the rapid production of large amounts of simulated data, extensibility and maintainability. Exoplanet research focusing on the characterization of super-Earths is currently limited to the handful of targets orbiting bright stars that are amenable to detailed study. This Letter proposes to look at alternative avenues to probe the surface and atmospheric properties of this category of planets, known to be ubiquitous in our galaxy.

Brightness temperatures and geometric albedos in the Kepler bandpass are constrained for 27 super-Earth candidates. A hierarchicalmore » Bayesian modeling approach is then employed to characterize the population-level reflective properties of these close-in super-Earths.

I argue that a better understanding of the incidence of stellar irradation on planetary surface and atmospheric processes is key to explain the diversity in albedos observed for close-in super-Earths.

Esteves, Lisa J. De; Jayawardhana, Ray, E-mail: esteves astro. We present a comprehensive analysis of planetary phase variations, including possible planetary light offsets, using eighteen quarters of data from the Kepler space telescope.

We model the full phase curve simultaneously, including primary and secondary transits, and derive albedos, day- and night-side temperatures and planet masses.

We find that KOI b , with a small eccentricity of 0. For six planets, we report a planetary brightness peak offset from the substellar point: of those, the hottest two Kepler b and HAT-P-7 b exhibit pre-eclipse shifts or on the evening-side, while the cooler four Kepler -7 b , Kepler -8 b , Kepler b , and Kepler b peak post-eclipse or on the morning-side.

Kepler b : A 2. A search of the time-series photometry from NASA's Kepler spacecraft reveals a transiting planet candidate orbiting the 11th magnitude G5 dwarf KIC with a period of days. The characteristics of the host star are well constrained by high-resolution spectroscopy combined with an asteroseismic analysis of the Kepler photometry, leading to an estimated mass and radius of 0.

The system passes a battery of testsmore » for false positives, including reconnaissance spectroscopy, high-resolution imaging, and centroid motion. A full BLENDER analysis provides further validation of the planet interpretation by showing that contamination of the target by an eclipsing system would rarely mimic the observed shape of the transits. The final validation of the planet is provided by 16 radial velocities RVs obtained with the High Resolution Echelle Spectrometer on Keck I over a one-year span.

The radiative equilibrium temperature is K for a planet in Kepler b 's orbit. Although there is no evidence that Kepler b is a rocky planet, it is the first confirmed planet with a measured radius to orbit in the habitable zone of any star other than the Sun. An independent planet search in the Kepler dataset. An extremely low-density super-Earth mass planet around Kepler The primary goal of the Kepler mission is the measurement of the frequency of Earth-like planets around Sun-like stars.

However, the confirmation of the smallest of Kepler 's candidates in long periods around FGK dwarfs is extremely difficult or even beyond the limit of current radial velocity technology. Transit timing variations TTVs may offer the possibility for these confirmations of near-resonant multiple systems by the mutual gravitational interaction of the planets. Aims: We previously detected the second planet candidate in the KOI system. The two candidates have relatively long periods about d and d and are in resonance.

We therefore searched for TTVs in this particularly promising system. The entire data allowed one to search for TTVs of the above signals, and to search for additional transit-like signals. Results: We detected strong anti-correlated TTVs of the d and d signals, dynamically confirming them as members of the same system.

Dynamical simulations reproducing the observed TTVs allowed us to also determine the masses of the planets. We found KOI Both planets have low densities of 0. Specifically, Kepler c is the lowest-density planet in the super-Earth mass range. Both planets are thus particularly amenable to modeling and planetary structure studies, and also present an interesting case where ground-based photometric follow-up of Kepler planets is very desirable. Kepler b is a 1. The corresponding high density of 6.

We also constrain the mass and period of the outer companion in the Kepler system from the long-term radial velocity trend and archival adaptive optics images. Kepler system Artist's Concept.

Our solar system now is tied for most number of planets around a single star, with the recent discovery of an eighth planet circling Kepler , a Sun-like star 2, light years from Earth.

The newly-discovered Kepler i -- a sizzling hot, rocky planet that orbits its star once every Machine learning is an approach to artificial intelligence in which computers "learn.

Absolute densities in exoplanetary systems. Photodynamical modelling of Kepler In favourable conditions, the density of transiting planets in multiple systems can be determined from photometry data alone. Dynamical information can be extracted from light curves, providing modelling is done self-consistently, i.

We apply this methodology to the Kepler planetary system. The derived planetary bulk densities are a factor of two more precise than previous determinations, and we find a discrepancy in the stellar bulk density with respect to a previous study. This leads, in turn, to a discrepancy in the determination of masses and radii of the star and the planets. In particular, we find that interior planet, Kepler b , has a size in between Mars and the Earth.

Given our mass and density estimates, we characterize the planetary interiors using a generalized Bayesian inference model. This model allows us to quantify for interior degeneracy and calculate confidence regions of interior parameters such as thicknesses of the core, the mantle, and ocean and gas layers.

We find that Kepler b and Kepler d have significantly thick volatile layers, and that the gas layer of Kepler b is likely enriched. On the other hand, Kepler c can be purely rocky.

Absolute densities in exoplanetary systems: photodynamical modelling of Kepler The derived planetary bulk densities are a factor of 2 more precise than previous determinations, and we find a discrepancy in the stellar bulk density with respect to a previous study. We find that Kepler b and Kepler d have significantly thick volatile layers and that the gas layer of Kepler b is likely enriched.

Observations of circumbinary planets orbiting very close to the central stars have shown that planet formation may occur in a very hostile environment, where the gravitational pull from the binary should be very strong on the primordial protoplanetary disk. Elevated impact velocities and orbit crossings from eccentricity oscillations are the primary contributors to high energy, potentially destructive collisions that inhibit the growth of aspiring planets.

In this work, we conduct high-resolution, inter-particle gravity enabled N-body simulations to investigate the feasibility of planetesimal growth in the Kepler system. We improve upon previous work by including planetesimal disk self-gravity and an extensive collision model to accurately handle inter-planetesimal interactions.

We find that super-catastrophic erosion events are the dominant mechanism up to and including the orbital radius of Kepler AB b , making in situ growth unlikely. It is more plausible that Kepler AB b migrated from a region beyond 1. Based on the conclusions that we have made for Kepler , it seems likely that all of the currently known circumbinary planets have also migrated significantly from their formation location with the possible exception of Kepler AB c.

Johannes Kepler and his contribution to Applied Mathematics. The worldwide renown of Johannes Kepler is based above all on his contribution to astronomy.

The 3 Kepler 's Laws relating to the planets are well known and will ensure that his name is remembered by future generations. Besides his astronomical work, Kepler also made important contributions in the fields of theology, physics, phylosophy and mathematics. The actual paper discusses the advances by Kepler in the application of mathematics to the solution of "real life problems".

The author made a concise account of some of the disciples by Kepler : Klug, Wieleitner, Caspar, Hammer, paying particular attention to works published by Kepler while he was living in Linz The Kepler 's contribution to applied mathematics is an example supremely worthy of emulation, the author concludes.

We identify three Kepler transiting planets, Kepler -7 b , Kepler b , and Kepler b , whose orbital phase-folded light curves are dominated by planetary atmospheric processes including thermal emission and reflected light, while the impact of non-atmospheric i. Therefore, those systems allow a direct view of their atmospheres without being hampered by the approximations used in the inclusion of both atmospheric and non-atmospheric processes when modeling the phase-curve shape.

We present here the analysis of Kepler b and Kepler b atmosphere based on their Kepler phase curve, while the analysis of Kepler -7 b was already presentedmore » elsewhere. The model we used efficiently computes reflection and thermal emission contributions to the phase curve, including inhomogeneous atmospheric reflection due to longitudinally varying cloud coverage.

We confirm Kepler b and Kepler b show a westward phase shift between the brightest region on the planetary surface and the substellar point, similar to Kepler -7 b. We find that reflective clouds located on the west side of the substellar point can explain the phase shift. The existence of inhomogeneous atmospheric reflection in all three of our targets, selected due to their atmosphere-dominated Kepler phase curve, suggests this phenomenon is common.

Therefore, it is also likely to be present in planetary phase curves that do not allow a direct view of the planetary atmosphere as they contain additional orbital processes. Finally, we discuss the potential detection of non-transiting but otherwise similar planets, whose mass is.

Obliquity variability could play an important role in the climate and habitability of a planet. Here we consider the spin axis dynamics of Kepler f and Kepler f, both of which reside in the habitable zone around their host stars. Using N-body simulations and secular numerical integrations, we describe their obliquity evolution for particular realizations of the planetary systems. We then use a generalized analytic framework to characterize regions in parameter space where the obliquity is variable with large amplitude.

However, for some other rotation periods of Kepler f or Kepler f, the lower-obliquity regions could become more variable owing to resonant interactions. Even small deviations from coplanarity e. In all cases, the high-obliquity region allows for moderate variations, and all obliquities corresponding to retrograde motion i. Confirmation of an exoplanet using the transit color signature: Kepler b , a blended giant planet in a multiplanet system.

Tingley, B. Aims: We announce confirmation of Kepler b , one of two proposed planets in this system. This is the first confirmation of an exoplanet based primarily on the transit color signature technique. Results: We report a confident detection of a transit color signature that can only be explained by a compact occulting body, entirely ruling out a contaminating eclipsing binary, a hierarchical triple, or a grazing eclipsing binary.

The resulting planet-star radius ratio is 0. Conclusions: This is the first confirmation of an exoplanet candidate based primarily on the transit color signature, demonstrating that this technique is viable from ground for giant planets. It is particularly useful for planets with long periods such as Kepler b , which tend to have long transit durations. While this technique is limited to candidates with deep transits from the ground, it may be possible to confirm earth-like exoplanet candidates with a few hours of observing time with an instrument like the James Webb Space Telescope.

Additionally, multicolor photometric analysis of transits can reveal unknown stellar neighbors. Jenkins, Jon M. The star has a large rotational vsin i of The velocities are indeed noisy, with scatter of 30 m s-1, but exhibit a period and phase that are consistent with those implied by transit photometry.

We securely detect the R-M effect, confirming the planet's existence and establishing its orbit as prograde. R-M measurements of a large sample of transiting planets from Kepler will provide a statistically robust measure of the true distribution of spin-orbit orientations for hot Jupiters around F and early G stars.

Based in part on observations obtained at the W. Keck Observatory, which is operated as a scientific partnership between the California Institute of Technology, the University of California, and the National Aeronautics and Space Administration.

The Observatory was made possible by the generous financial support of the W. Keck Foundation. Asteroseismic inversions in the Kepler era: application to the Kepler Legacy sample.

In the past few years, the CoRoT and Kepler missions have carried out what is now called the space photometry revolution. This revolution is still ongoing thanks to K2 and will be continued by the Tess and Plato2. However, the photometry revolution must also be followed by progress in stellar modelling, in order to lead to more precise and accurate determinations of fundamental stellar parameters such as masses, radii and ages.

In this context, the long-lasting problems related to mixing processes in stellar interior is the main obstacle to further improvements of stellar modelling.

In this contribution, we will apply structural asteroseismic inversion techniques to targets from the Kepler Legacy sample and analyse how these can help us constrain the fundamental parameters and mixing processes in these stars. Our approach is based on previous studies using the SOLA inversion technique [1] to determine integrated quantities such as the mean density [2], the acoustic radius, and core conditions indicators [3], and has already been successfully applied to the 16 Cyg binary system [4].

We will show how this technique can be applied to the Kepler Legacy sample and how new indicators can help us to further constrain the chemical composition profiles of stars as well as provide stringent constraints on stellar ages.

Comet 67P Seen by Kepler. NASA's planet-hunting Kepler spacecraft observed the comet during the final month of the Rosetta mission, while the comet was not visible from Earth. This animation is composed of images from Kepler of the comet. From Sept. From the distant vantage point of Kepler , the comet's nucleus and tail could be observed. The long-range view from Kepler complements the closeup view of the Rosetta spacecraft, providing context for the high-resolution investigation Rosetta performed as it descended closer and closer to the comet.

During the two-week period of study, Kepler took a picture of the comet every 30 minutes. The animation shows a period of The comet is seen passing through Kepler 's field of view from top right to bottom left, as outlined by the diagonal strip. The white dots represent stars and other regions in space studied during K2's tenth observing campaign. As a comet travels through space it sheds a tail of gas and dust.

The more material that is shed, the more surface area there is to reflect sunlight. A comet's activity level can be obtained by measuring the reflected sunlight. Analyzing the Kepler data, scientists will be able to determine the amount of mass lost each day as comet 67P travels through the solar system. Kepler AutoRegressive Planet Search. NASA's Kepler mission is the source of more exoplanets than any other instrument, but the discovery depends on complex statistical analysis procedures embedded in the Kepler pipeline.

A particular challenge is mitigating irregular stellar variability without loss of sensitivity to faint periodic planetary transits. This proposal presents a two-stage alternative analysis procedure. Second, a novel matched filter is used to create a periodogram from which transit-like periodicities are identified. The proposed research will complete application of the KARPS methodology to the prime Kepler mission light curves of , stars, and compare the results with Kepler Objects of Interest obtained with the Kepler pipeline.

Important subsamples will be extracted including Habitable Zone planets, hot super-Earths, grazing-transit hot Jupiters, and multi-planet systems. Groundbased spectroscopy of poorly studied candidates will be performed to better characterize the host stars.

The autocorrelation function and nonstationarity measures will be used to identify spotted stars at different stages of autoregressive modeling. Periodic variables with folded light curves inconsistent with planetary transits will be identified; they may be eclipsing or mutually-illuminating binary star systems. KARPS procedures will then be applied to archived K2 data to identify planetary transits and characterize stellar variability.

Radial velocity confirmation of Kepler b. Lillo-Box, J. The object transiting the star Kepler was recently assessed as being of planetary nature. The confirmation was achieved by analysing the light-curve modulations observed in the Kepler data. However, quasi-simultaneous studies claimed a self-luminous nature for this object, thus rejecting it as a planet.

In this work, we apply anindependent approach to confirm the planetary mass of Kepler b by using multi-epoch high-resolution spectroscopy obtained with the Calar Alto Fiber-fed Echelle spectrograph CAFE.

We obtain the physical and orbital parameters with the radial velocity technique. In particular, we derive a value of 1. We have demonstrated the success of a citizen science approach with the project's discoveries including PH1 b , a transiting circumbinary planet in a four star system. The majority of these detections found by TPS are triggered by transient events and are not valid planet candidates.

To identify planetary candidates from the detected TCEs, a human review of the validation reports, generated by the Kepler pipeline for each TCE, is performed by several Kepler team members. We have undertaken an independent crowd-sourced effort to perform a systematic search of the Kepler Q TCE list.

With the Internet we can obtain multiple assessments of each TCE's data validation report. Planet Hunters volunteers evaluate whether a transit is visible in the Kepler light curve folded on the expected period identified by TPS. We present the first results of this analysis. Kepler Certified False Positive Table. A KOI is certified as a false positive when, in the judgement of the FPWG, there is no plausible planetary interpretation of the observational evidence, which we summarize by saying that the evidence for a false positive is compelling.

This certification process involves detailed examination using all available data for each KOI, establishing a high-reliability ground truth set. Follow-up observers may find the CFP table useful to avoid observing false positives.

The open circle near KOI b is the millisecond pulsar companion discovered by Follow-up observations are planned as well as contin- ued with the Kepler instrument to help unravel their nature. Funding for this Discovery mission is Kepler b : a massive warm Jupiter in a day eccentric orbit transiting a giant star. We study the Kepler object Kepler , an evolved star ascending the red giant branch.

By deriving precise radial velocities from multi-epoch high-resolution spectra of Kepler taken with the CAFE spectrograph at the 2. Current models of planetary evolution in the post-main-sequence phase predict that Kepler b will be most likely engulfed by its host star before the latter reaches the tip of the red giant branch.

Spiegel, David S. We find that published Kepler and Spitzer data for HAT-P-7 b appear to require an extremely hot upper atmosphere on the dayside, with a strong thermal inversion and little day-night redistribution. The Spitzer data for TrES-2 suggest a mild thermal inversion with moderate day-night redistribution. We examine the effect of nonequilibrium chemistry on TrES-2 model atmospheres and find that methane levels must be adjusted by extreme amounts in order to cause even mild changes in atmosphericmore » structure and emergent spectra.

Finally, we consider how the Kepler -band optical flux from a hot exoplanet depends on the strength of a possible extra optical absorber in the upper atmosphere. We find that the optical flux is not monotonic in optical opacity, and the non-monotonicity is greater for brighter, hotter stars. Kepler Data Release 4 Notes. These notes have been prepared to give Kepler users of the Multimission Archive at STScl MAST a summary of how the data were collected and prepared, and how well the data processing pipeline is functioning on flight data.

Data release 3 is meant to give users the opportunity to examine the data for possibly interesting science and to involve the users in improving the pipeline for future data releases. To perform the latter service, users are encouraged to notice and document artifacts, either in the raw or processed data, and report them to the Science Office.

The Kepler Full Frame Images. NASA's exoplanet discovery mission Kepler provides uninterrupted 1-min and min optical photometry of a square degree field over a 3. Downlink bandwidth is filled at these short cadences by selecting only detector pixels specific to preselected stellar targets. The full-frame images provide a resource for potential Kepler Guest Observers to select targets and plan observing proposals, while also providing a freely-available long-cadence legacy of photometric variation across a swathe of the Galactic disk.

With years of Kepler data currently available, the measurement of variations in planetary transit depths over time can now be attempted. To do so, it is of primary importance to understand which systematic effects may affect the measurement of transits. We aim to measure the stability of Kepler measurements over years of observations.

We find a systematic variation in the depth of the primary transit, related to quarters of data and recurring yearly. Within seasons, we find no evidence for trends. We speculate that the cause of the seasonal variations could be unknown field crowding or instrumental artifacts. Our results show that care must be taken when combining transits throughout different quarters of Kepler data. Measuring the relative planetary radius of HAT-P-7 b without taking these systematic effects into account leads to unrealistically low error estimates.

This effect could be present in all Kepler targets. With a period of days, conditions are prompt to be similar to those of Earth, and while Kepler b orbits the HZ of its parent star, its habitability could also be affected by the presence of an exomoon.

Motivated by the need to understand conditions of habitability and orbital stability of Kepler b , we have performed a series of N-body integrations to examine the possibility of the exoplanet hosting an exomoon s. Our results give a range of physical parameters leading to stable orbits for exomoons around this habitable super Earth. The discovery of many planets using the Kepler telescope includes 10 planets orbiting eight binary stars.

Three binaries, Kepler - 16 , Kepler , and Kepler , have at least one planet in the circumbinary habitable zone BHZ.

We constrain the level of high-energy radiation and the plasma environment in the BHZ of these systems. With the time-dependent BHZ limits established, a self-consistent model is developed describing the evolution of stellar activity and radiation properties as proxies for stellar aggression toward planetary atmospheres. Modeling binary stellar rotation evolution, including the effect of tidal interaction between stars in binaries, is key to establishing the environment around these systems.

We find that Kepler - 16 and its binary analogs provide a plasma environment favorable for the survival of atmospheres of putative Mars-sized planets and exomoons. Tides have modified the rotation of the stars in Kepler , making its radiation environment less harsh in comparison to the solar system.

This is a good example of the mechanism first proposed by Mason et al. Kepler has an environment similar to that of the solar system with slightly better than Earth radiation conditions at the inner edge of the BHZ. With the time-dependent BHZ limits established, a self-consistent model is developed describing the evolution of stellar activity and radiation propertiesmore » as proxies for stellar aggression toward planetary atmospheres.

Extragalactic Science With Kepler. Although designed as an exoplanet and stellar astrophysics experiment, the Kepler mission provides a unique capability to explore the essentially unknown photometric stability of galactic systems at millimag levels using Kepler 's blend of high precision and continuous monitoring.

Time series observations of galaxies are sensitive to both quasi-continuous variability, driven by accretion activity from embedded active nuclei, and random, episodic events, such as supernovae.

In general, galaxies lacking active nuclei are not expected to be variable with the timescales and amplitudes observed in stellar sources and are free of source motions that affect stars e. These sources can serve as a population of quiescent, non-variable sources, which may be used to quantify the photometric stability and noise characteristics of the Kepler photometer.

A factor limiting galaxy monitoring in the Kepler FOV is the overall lack of detailed quantitative information for the galaxy population. Despite these limitations, a significant number of galaxies are being observed, forming the Kepler Galaxy Archive. Observed sources total approximately , , and in Cycles Cycle 3 began in June In this poster we interpret the properties of a set of 20 galaxies monitored during quarters 4 through 8, their associated light curves, photometric and astrometric precision and potential variability.

We describe data analysis issues relevant to extended sources and available software tools. In addition, we detail ongoing surveys that are providing new photometric and morphological information for galaxies over the entire field.

These new datasets will both aid the interpretation of the time series, and improve source selection, e. Kepler , the Ultimate Aristotelian. A comparison is made between Aristotelian and Newtonian versions of Laws of Motion. Kepler was successful in proving the 2 laws of motion of a single planet - to the extent that agreement with a framework of theory constitutes a proof. Of course he invented his framework of causes after the event, to fit the motions that had been already been quantified - but it may seem to you that Kepler 's mainly mechanistic way explanation could have been considered by his contemporaries just as reasonable as Newton's action at a distance.

It could be now apprecated that there was a window of less than 50 years before Newton's total synthesis. No-one previously had had the motivation to create a system of "celestial physics" based on a judicious use of Aristotelian principles. Yet this is what Kepler achieved. NASA's Kepler Mission conducted six teacher professional development workshops on the search for Earth-size in the habitable zone of Sun-like stars. The Kepler Mission launched in March, As a part of International Year of Astronomy , this series of one-day workshops were designed and presented for middle and high school teachers, and science center and planetarium educators prior to and after the launch.

The professional development workshops were designed using the best practices and principals from the National Science Education Standards and similar documents. Sharing the outcome of our plans, strategies and formative evaluation results can be of use to other Education and Public Outreach practitioners who plan similar trainings.

The workshops combined a science content lecture and discussion, making models, kinesthetic activities, and interpretation of transit data. The emphasis was on inquiry-based instruction and supported science education standards in grades The workshop plan, teaching strategies, and lessons learned from evaluation will be discussed.

Future events are planned. Teachers participate in human orrery. The Kepler SOC Science Operations Center pipeline calibrates the pixels of the target apertures for each star, corrects light curves for systematic error, and detects TCEs threshold-crossing events that may be due to transiting planets. KOIs are TCEs that are determined to be either likely transiting planets or astrophysical false positives such as background eclipsing binary stars. The classifier uniformly and consistently applies heuristics developed by TCERT as well as other diagnostics to the Q1-Q 16 TCEs to produce a more robust and reliable catalog of planet candidates than is possible with only human classification.

In this work, we estimate planet occurrence rates, based on the machine-learning-produced catalog of Kepler planet candidates. Kepler was selected as the 10th mission of the Discovery Program. Kepler Data Release 3 Notes. This describes the collection of data and the processing done on it so when researchers around the world get the Kepler data sets which are a set of pixels from the telescope of a particular target star, galaxy or whatever over a 3 month period they can adjust their algorithms fro things that were done like subtracting all of one particular wavelength for example.

He discovered it by looking through a refracting telescope. In the image above shows the Orion Nebula in both visual and infared image which is interesting to note because this means that the nebula gives off two different frequencies. If you look in the center of the image, there are four, young and bright, stars that hold the nebula together. They emit this ultraviolet light that creates a cavity in the nebula. This causes a disruption in the growth of hundreds of smaller stars.

These four young stars are called " Trapezium " because they are arranged in a shape of a trapezoid. The nebula gives off this dominant red glow because the nebula is mostly made up of ionized Hydrogen. On the right side of the image, there is a noticable greenish tint. The people that study this nebula does not know where this greenish tint comes from. The Andromeda Galaxy is one of the biggest galaxies in the general area where our Milky Way galaxy is located. It is thought to have about twice as much stars that the Milky Way has.

The Andromeda galaxy is thought to have formed 10 billion years ago from a collision and merging with another galaxy. This also explains the massive size of the galaxy itself because the galaxy is thought to be an accumilation of merging with smaller galaxies.

In the Andromeda galaxy, researches have found the most number of black holes of the galaxies that they have observed.
