Latest Extrasolar planets Stories
Light from a "super-Earth" planet that lies beyond our solar system has been detected for the first time by NASA's Spitzer Space Telescope.
Solar systems that have “hot Jupiter-type” planets closely orbiting host stars likely do not have Earth-like planets neighboring them.
After re-evaluating information collected back in February, scientists reportedly confirmed on Friday that they had indeed discovered a planet outside of our solar system that is capable of supporting life.
While scientists believe conditions suitable for life might exist on the so-called "super-Earth" in the Gliese 581 system, it's unlikely to be transferred to other planets within that solar system.
World-renowned Swiss astronomers Michel Mayor and Didier Queloz of the Geneva Observatory have been awarded the 2011 BBVA Foundation Frontiers of Knowledge Award in Basic Sciences for their work on exoplanets.
An international team of scientists led by Carnegie's Guillem Anglada-Escudé and Paul Butler has discovered a potentially habitable super-Earth orbiting a nearby star.
An international team, including three astronomers from the European Southern Observatory (ESO), has used the technique of gravitational microlensing to measure how common planets are in the Milky Way.
Only 15 planets and 30 moons could potentially support alien life, according to a new online catalog of habitable planets launched by astronomers on Monday.
A University of Hawaii astronomer is credited with capturing the first direct image of a planet in the process of being formed around its star.
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.
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...
