Latest Extrasolar planets Stories
Astronomers say they've witnessed the death of a planet, which found its journey ended by way of its own star.
Scientists collaborated recently to produce simulations of Earth-like planets being vaporized in order to help astronomers have a better grasp of what to look for in the atmosphere of candidate super-Earths.
Astronomers have detected a new exoplanet 33 light-years away that is two-thirds the size of Earth, making it the nearest known world to our solar system that is smaller than our home planet.
Astronomers have observed one planet in another solar system, similar to Jupiter, giving off a powerful burst of evaporation after passing by its parent star.
An international team of astronomers have uncovered a clever new way of studying the atmosphere of an exoplanet in more detail.
A technique that allows radio astronomers to combine observations made simultaneously by multiple arrays has yet to detect any signs of extraterrestrial broadcast signals, Australian researchers have confirmed.
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.
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...
