Latest Extrasolar planets Stories
WASHINGTON, July 15 /PRNewswire-USNewswire/ -- Astronomers using NASA's Hubble Space Telescope have confirmed the existence of a baked object that could be called a "cometary planet." The gas giant planet, named HD 209458b, is orbiting so close to its star that its heated atmosphere is escaping into space.
A team of astronomers from Germany, Bulgaria and Poland have used a completely new technique to find an exotic extrasolar planet.
Astronomers have measured a superstorm for the first time in the atmosphere of an exoplanet, the well-studied â€œhot Jupiterâ€ HD209458b.
By detecting the faint dimming in the light emitted by stars during a transit event, CoRoT has detected six new exoplanets - each with its own peculiar characteristics - and one brown dwarf.
A new robotic telescope has had first light at ESOâ€™s La Silla Observatory, in Chile. TRAPPIST (TRAnsiting Planets and PlanetesImals Small Telescope) is devoted to the study of planetary systems through two approaches: the detection and characterization of planets located outside the Solar System (exoplanets) and the study of comets orbiting around the Sun.
Astronomers are reporting today the discovery of a planetary system way out of tilt, where the orbits of two planets are at a steep angle to each other.
Weird orbits of neighbors can make 'habitable' planets not so habitable.
The hottest known planet in the Milky Way galaxy may also be its shortest-lived world.
Astronomers have discovered nine new transiting exoplanets, some of which were found to orbit in the opposite direction as their host stars.
Combining observations from the CoRoT satellite and the ESO HARPS instrument, astronomers have discovered the first â€œnormalâ€ exoplanet that can be studied in great detail.
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...
