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

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

Artwork: Artist's view of Beta Pictoris b, a giant exoplanet with a mass equivalent to 9 times the mass of Jupiter orbit around 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 - or Astronomical Units - which is about the distance Saturn is from the Sun. The planet has a mass of about nine Jupiter masses and is right mass and location to explain the observed warp in the inner parts of the disc — Artist view of Beta Pictoris b - Beta Pictoris b.

On the right, the light of this star is amplified by gravitational lens effect. The gravitational lens effect occurs when the gravitational field of a star acts as a magnifying glass by amplifying the light emitted by a farther star. This amplification is measurable, and when the foreground star is accompanied by a planet, a second peak of intensity in the life rays appears more weakly. Illustration showing at left the observation of faint light emitted by a distant star, at right, the light of the same star magnified by a gravitational lens. Microlensing occurs when the gravitational field of a star acts like a lens, magnifying the light of a distant background star. Possible planets orbiting the foreground star can cause detectable anomalies in the lensing event light curve

It orbits Kepler-186, a red dwarf located in the constellation of Swan, between 490 and 500 light years of the Earth. Kepler-186f, the first Earth-size Planet in the Habitable Zone. The artist's concept depicts Kepler-186f, the first validated Earth-size planet to orbit a distant star in the habitable zone - a range of distance from a star where liquid water might pool on the planet's surface. The discovery of Kepler-186f confirms that Earth-size planets exist in the habitable zones of other stars and signals a significant step closer to finding a world similar to Earth. The size of Kepler-186f is known to be less than ten percent larger than Earth, but its mass, composition and density are not known. Previous research suggests that a planet the size of Kepler-186f is likely to be rocky. Prior to this discovery, the “” record holder”” for the most “” Earth-like”” planet went to Kepler-62F, which is 40 percent larger than the size of Earth and orbits in its star's habitable zone. Kepler-186f orbits its star once every 130 days and receives one-third the energy that Earth does from the sun, placing it near the outer edge of the habitable zone. If you could stand on the surface of Kepler-186f, the brightness of its star at high noon would appear as bright as our sun is about an hour before sunset on Earth. Kepler-186f resides in the Kepler-186 system about 500 light-years from Earth in the constellation Cygnus. The system is also home to four inner planets, seen lined up in orbit around a host star that is half the size and mass of the sun — Exoplanete Kepler-186f - Kepler-186f, the first Earth-size Planet in the Habitable Zone: Kepler-186f is the first Earth-size planet in the habitable zone of its star to be discovered.

Exoplanete around Beta Hydri: Beta Hydri is the brightest star in the constellation of the male Hydra. Located about 24.4 light years from Earth, Beta Hydri is often studied as it could give information about what could happen to the Sun in the next 2.5 billion years. Larger and slightly more massive than the latter, it probably has planets. Beta Hydri is a star in the southern circumpolar constellation of Hydrus. Located 24.33 light-years away, it could harbor a true Jupiter-analogue, though 4 times more massive

Exoplanete near a star at the end of life - A dying star sheds its outer layers - An artist's view of a star that, like the Sun at the end of life, turns into a red giant, and expels its upper layers into concentric circles, before becoming a white dwarf. In the foreground, an exoplanet distant from its star that sees its surface reheat. 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. These ejected layers eventually form a planetary nebula. What will subsequently remain of the star is a small, extremely hot core which cools off to become a white dwarf. In this image a red giant star expels its first of many shells of gas into space. In the years to come this spherical shell will grow outward, its circumference eventually expanding far beyond the orbit of this planet. As for this planet, being so far from its parent sun for most of its life has kept it in a deep, dark freeze for the past ten billion years (think Pluto). It has been during only the past 100 million years, when its sun first blossomed into a red giant, that this planet has experienced such light and warmth. This effluence is short - lived, however; in about another million years darkness and cold will again be the norm for this world — Exoplanete near a star at the end of life - A dying star sheds its outer layers - An artist's view of a star that, like the Sun at the end of life, turns into a red giant, and expels its upper layers into concentric circles, before becoming a white dwarf.

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)

The discovery of Kepler - 186f confirms that Earth - size planets exist in the habitable zones of other stars and signals a significant step closer to finding a world similar to Earth. The size of Kepler - 186f is known to be less than ten percent larger than Earth, but its mass, composition and density are not known. Previous research suggests that a planet the size of Kepler - 186f is likely to be rocky.
