Latest Extrasolar planets Stories
Scientists working with NASA’s Spitzer Space Telescope have found that exoplanets known as hot Jupiters are not all alike and appear to have a wide range of climates.
An international team of astronomers has made the most detailed examination to date of the atmosphere around a Jupiter-like exoplanet using the Keck Observatory, one of the two largest optical telescopes in the world.
Another new planetary system has been discovered by Kepler scientists, and this one happens to be home to the smallest planet ever discovered, circling around a star that is strikingly similar to our Sun.
Astronomers discovered that the HAT-P-7 planetary system includes at least two giant planets and one companion star.
According to newly released images from the Hubble Space Telescope, a vast debris belt circling around a nearby star is wider than scientists believe, and the unusual orbit of a planet traveling around that star could be to blame.
In a new study, researchers have taken another look at Hubble images from 2004 and 2006, and are now reaffirming that Fomalhaut b is indeed a “massive planet”. The study's lead author Dr. Thayne Currie recently talked with redOrbit about bringing Fomalhaut b back from the dead.
A new study suggests that the nearby star Fomalhaut hosts a massive "zombie" exoplanet that was previously thought to not exist, but is back from the dead.
One nearby super-Earth planet could have a lot more "bling" on it than our planet, because astronomers say it maybe a diamond 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...
