Latest Extrasolar planets Stories
A nearby star is pummeling a companion planet with a barrage of X-rays 100,000 times more intense than the Earth receives from the sun.
Astronomers using ESO’s world-leading exoplanet hunter HARPS have today announced a rich haul of more than 50 new exoplanets, including 16 super-Earths, one of which orbits at the edge of the habitable zone of its star.
A team of scientists at Germany’s Max-Planck Institute for Astronomy has discovered a potentially habitable planet about 3.6 times as massive of Earth orbiting the star HD 85512, roughly 36.23 light years away.
Astronomers said on Thursday that they have discovered the darkest known exoplanet they say is the size of Jupiter.
The French-led CoRoT satellite has found ten new planets outside our Solar System.
Scientists said on Monday that a rocky planet outside our solar system is the first to meet key requirements for sustaining life.
Scientists said on Wednesday the majority of the 500 planets detected around stars besides the Sun appear to spin the same way the star does.
An international team of astronomers have revealed details of a "super-exotic" exoplanet that would make the planet Pandora in the movie Avatar pale in comparison.
Jupiter-like worlds around other stars push shock waves ahead of them, according to a team of UK astronomers.
Detecting exoplanets that orbit at large distances from their star remains a challenge for planet hunters.
Extrasolar Planet -- An extrasolar planet is a planet orbiting around a star other than the Sun. Extrasolar planets were first discovered in the 1990s as a result of improved telescope technology, CCD and computer-based image processing which allowed far more accurate measurements of stellar motions. The first extrasolar planets were reported by the astronomer Aleksander Wolszczan in 1993, orbiting the pulsar PSR 1257+12. Subsequent investigation has determined that they are only planets...
Epsilon Eridani -- Epsilon Eridani is a main-sequence star in the constellation of Eridanus (the river). It is often used in science fiction because it is extremely sunlike, and in the fictional Star Trek universe it is the home sun of the planet Vulcan which is home to Mr. Spock. It is the third closest star visible without a telescope. It has 85% of the Sun's mass, almost that much of its diameter, and 28% of its luminosity. It is 10.5 light years from Earth. Its spectrum is...
La Silla Observatory -- La Silla is a 2400-m mountain, bordering the southern extremity of the Atacama desert in Chile. It is located about 160 Km north of La Serena. Its geographical coordinates are: Latitude 29 15' south & Longitude 70 44' west. Originally known as Cinchado, the mountain was renamed La Silla (the saddle) after its shape. It rises quite isolated and remote from any artificial light and dust sources (astronomy's worst enemies). La Silla was the first ESO...
