Latest Extrasolar planets Stories
An international team of astronomers has discovered a fourth giant planet, HR 8799e, outside our solar system.
The atmosphere around a super-Earth exoplanet has been analyzed for the first time by an international team of astronomers using ESOâ€™s Very Large Telescope.
Galactic cannibalism brings an exoplanet of extragalactic origin within astronomers' reach.
Observations from NASA's Spitzer Space Telescope reveal a distant planet with a warm spot in the wrong place.
UA astronomers have developed a way to see faint planets previously hidden in their star's glare. The new mode enables scientists to search for planets closer to the star than has been previously possible.
Bad news for planet hunters: most of the "hot Jupiters" that astronomers have been searching for in star clusters were likely destroyed long ago by their stars.
Any driver whoâ€™s seen deer silhouetted by the headlights of an oncoming car knows that vital information can be conveyed by the outlines of objects.
Astronomers at the European Southern Observatory (ESO) have discovered five planets orbiting a star in what is being called "the biggest discovery of so-called exoplanets since the first was logged 15 years ago."
Hundreds of extrasolar planets have been found over the past decade and a half, most of them solitary worlds orbiting their parent star in seeming isolation.
Astronomers using NASA's Hubble Space Telescope have confirmed the existence of a baked object that could be called a "cometary planet."
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...
