Latest Extrasolar planets Stories
A previously-discovered alien world that has an atmosphere that seems to be made up entirely of water vapor or some form of heavy molecule has now been discovered to be very cloudy.
University of Arizona astronomers are scratching their heads after discovering the most distant orbiting planet to date which is throwing a wrench in planet formation theories.
A census of planets outside our solar system pierces the haze surrounding five "hot Jupiters" to find conclusive signs of atmospheric water. College
Two teams of scientists have discovered faint signatures of water in the atmospheres of five exoplanets. This is the first study to conclusively measure and compare the profiles and intensities of these signatures on multiple worlds.
What was believed to be the first-ever discovered planet to be comprised largely of diamond most likely does not have a high content of the precious mineral after all.
Astronomers using data from NASA's Kepler and Spitzer space telescopes have created the first cloud map of a planet beyond our solar system, a sizzling, Jupiter-like world known as Kepler-7b.
The number of exoplanets discovered by astronomers since the beginning of the Space Age some five decades ago suggests there are possibly over 100 billion such worlds outside our solar system, according to one Caltech astronomer involved with NASA’s Kepler mission.
An international team of scientists has devised a method for measuring the internal properties of a star that offers more accurate assessments of the star's orbiting planets.
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...
