Latest Extrasolar planets Stories
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.
Astronomers using NASA's Chandra observatory were able to witness an eclipsing planet for the first time.
Using imagery from the Hubble Space Telescope, astronomers have determined that a planet orbiting a star close to our solar system has a deep azure blue color when seen from space, much like Earth.
Astronomers search for planets using several different techniques; the most popular of which is to measure how a star "wobbles." As the surrounding planets orbit the star, their gravitational fields will cause the star to shift back and forth in response.
Hot Jupiters, despite their close-in orbits, are not regularly consumed by their stars, as a new study conducted with data from NASA’s Kepler Space Telescope reveals.
A scientific team led by University of Louisville doctoral student Karen Collins has discovered a hot Saturn-like planet in another solar system 700 light-years away.
Scientists announced during the American Astronomical Society’s national meeting in Indianapolis this week that they have discovered a hot Saturn-like planet in another solar system 700 light-years away.
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...
