Exoplanete Kelt-11b - Artist's view of Kelt-11b orbiting his star KELT-11, located 320 light years from Earth in the constellation of the Lion. Kelt-11b is an exoplanet larger than Jupiter and very close to its star. It was discovered in 2016. Kelt-11b is an exoplanet orbiting around the yellow subgiant star KELT-11 about 320 light-years away from Earth

Planetary system around Trappist-1 - Artist's impressions of the TRAPPIST-1 planetary system: Artist's view of extrasolar planets around the red dwarf star TRAPPIST-1. At least seven exoplanets the size of the Earth are orbiting this star 40 light years ago in the constellation Aquarius. All could contain water. This artist's impression shows several of the planets orbiting the ultra-cool red dwarf star TRAPPIST-1. New observations, when combined with very sophisticated analysis, have now yielded good estimates of the densities of all seven of the Earth-sized planets and suggest that they are rich in volatile materials, probably water

Mission New Worlds: The New Worlds mission is a space mission proposal being studied by NASA. Its concept is based on the association of a space telescope with a large occulter (starshade) which places in space a long distance from it (several tens of thousands of kilometres) and designed to block the light of the central star in order to observe its exoplanets. Observations could be made with an existing space telescope, such as the James-Webb Space Telescope (JWST) once launched. A space telescope observes planets orbiting a distant star whose glare has been blocked by a flower-shaped screen the size of a football field. In reality, the starshade would be almost as far from the telescope as the moon is from earth

When a star like our sun nears the end of its life, it expands to more than 50 times its original diameter, becoming a red giant. Then over the next several tens of thousands of years the star episodically ejects its outer layers into space, sometimes producing concentric shells.

Launched at the end of December 2006, this satellite studies the physical phenomena occurring inside the stars. It is also used for the detection of extrasolar planets by observing the periodic micro-eclipses that these planets cause by passing in front of their mother star. Artist's view of COROT, the exoplanet hunter mission led by CNES, with ESA participation. Launched in December 2006, COROT is placed on a circular, polar orbit around Earth that allow for continuous observations of two large and opposite regions in the sky for more than 150 days each. Within each region there are many selected fields that will be monitored in turn. The reason for the oppositely sited regions is that, because of the Earth's movement around the Sun, the sun's rays start to interfere with the observations after 150 days.

Observation of an exoplanete by interferometry - Observation of an exoplanet with interferometry - Illustration of the principle of direct observation of an exoplanete by interferometry with space telescopes. Places in different places, each telescope observes the light of the star with a slight decay relative to each other. Together these observations would reduce the apparent luminosite of the star and amplify the luminosite of the planet. Optical interferometry combines the light of multiple telescopes to perform the work of a single, much larger telescope. This is possible due to the interaction of light waves, also called interference. Their interaction can be used to cancel out the blinding glare of bright stars or to measure distances and angles precisely

Artist's view of a hot Jupiter - Exoplanet - Hot Jupiter - Artist's view of a gas giant exoplanet very close to its star. Many of the extra - solar planets which have been discovered in recent years are large, massive, and orbit surprisingly close to their parent stars. These are believed to be gas giant planets similar to Jupiter. Since they're so close to their sun, they're hot. Thus the common term for them has become “” hot Jupiter””. This one is hot enough to glow a dull red even on its night side. The existence of these planets has proven that the arrangement of other solar systems need not closely resemble our own

Exoplanete Tau Ceti e: Tau Ceti e would be an extrasolar planet (exoplanet) of a super-earth type orbit in the habitable zone of the star Tau Ceti. It would be located approximately 12 light years away from Earth in the direction of the constellation of the Whale. Tau Ceti is a Super-earth located in its star's habitable area. Tau Ceti is a star in the constellation Cetus that is spectrally similar to the Sun, although it has only about 78% of the Sun's mass. At a distance of just under 12 light-years (3.7 parsecs) from the Solar System, it is a relatively nearby star

Exoplanete OGLE-2013-BLG-0341L Bb - Artist's view: OGLE-2013-BLG-0341L Bb is an exoplanet about twice the mass of the Earth gravitating around the red dwarf OGLE-2013-BLG-0341L B, a secondary component of the binary star OGLE-2013-BLG-0341L located in the constellation. OGLE-2013-BLG-0341LBB, is located in the constellation Sagittarius, about 3,000 light-years away. It is twice the mass of Earth, and orbits one of the stars in the binary system at almost exactly the same distance from which Earth orbits the Sun. But its star is 400 times dimmer than our Sun, so the exoplanet is very cold - around minus 213 degrees Celsius

Beta Pictoris b - Artist's view of Beta Pictoris b, a giant exoplanet with a mass equivalent to 9 times the mass of Jupiter orbiting the star Beta Pictoris. This artist's impression shows how the planet inside the disc of Beta Pictoris may look. Only 12 million years old, or less than three - thousandths of the age of the Sun, Beta Pictoris is 75% more massive than our parent star. It is located about 60 light - years away towards the constellation of Pictor (the Painter) and is one of the best - known examples of a star surrounded by a dusty debris disc. Earlier observations showed a warp of the disc, a secondary inclined disc and comets falling onto the star, all indirect, but tell - tale signs that strongly suggested the presence of a massive planet. Observations done with the NACO instrument on Eso's Very Large Telescope in 2003, 2008 and 2009, have proven the presence of a planet around Beta Pictoris. It is located at a distance between 8 and 15 times the Earth - Sun separation -

Exoplanete Alpha Centauri Bb - Artist's impression of the planet orbiting Alpha Centauri B: Artist's view of the planet Alpha Centauri Bb, also known as Gliese 559 Bb. Discovered in 2012 its existence is questioned. It would be orbiting the dwarf star Alpha Centauri B at a distance of 4.37 light years in the constellation Centauri. The planet is not in the habitable zone of the star, as it orbits far too close to the star. Alpha Centauri Bb was a proposed exoplanet orbiting the K-type main-sequence star Alpha Centauri B, located 4.37 light-years from Earth in the southern constellation of Centaurus. Its existence was announced in October 2012 but in October 2015, a scientific paper disproved the existence of the planet. Alpha Centauri B dominates the sky. Just above it to the right is a very bright star: Alpha Centauri A. And above that to the right is another star: our sun

Artist's view of the exoplanet OGLE-2005-BLG-390L b: Artist's view of the exoplanet OGLE-05-390L b in the constellation Scorpio. Its mass is estimated at 5.5 times that of Earth, distinguishing it from the smallest of our gas planets, Uranus (15 Earth masses) and Neptune (17). It is most likely solid, composed of ice and rocks. But if her mass is higher, then she could be an ice giant like Uranus and Neptune.

Detection of an exoplanet by radial velocity - Detection of an exoplanet: Radial velocity or Doppler method - This detection method is based on the study of the light spectrum of the star. A planet orbiting around a star periodically influences the movement of that star. By Doppler effect (the star's light wave shifts to blue when it approaches and decals to red when it moves away), we can measure the radial velocity of the star and know the position of the planet's orbit. An exoplanet orbiting a larger star could produce changes in position and velocity of the star as they orbit their common center of mass. Those variations in the radial velocity are known in studying the spectral lines of the star due to the Doppler effect (blue shift when the star is approaching, redshift when it is receding)

This cluster contains about 50,000 stars and is riding high above our own Milky Way galaxy. Like other globular clusters, it may be the remnant of the core of a small galaxy long ago adsorbed by the larger Milky Way. There may even be a black hole lurking at its center. Globular clusters usually contain very old stars. Any planets to be found in one would likely be much older than the Earth
