Latest Terrestrial planet Stories
Using NASAâ€™s Spitzer Space Telescope, an international team of astronomers have found that at least 1 in 100 white dwarf stars show evidence of orbiting asteroids and rocky planets, suggesting these objects once hosted Solar Systems similar to our own.
Does a twin Earth exist somewhere in our galaxy? Astronomers are getting closer and closer to finding an Earth-sized planet in an Earth-like orbit.
CAPE CANAVERAL, Fla., March 5 /PRNewswire-USNewswire/ -- NASA's Kepler mission to seek other Earth-like planets is undergoing final preparations for liftoff Friday, March 6, from Pad 17-B at Cape Canaveral Air Force Station in Florida.
NASA reports a successful launch on Friday night for a revolutionary new space telescope that will seek out other Earth-like planets in the Milky Way galaxy. Scientists hope Kepler will find planets potentially hospitable to life.
When NASA's Kepler telescope rockets into the night sky on Friday, March 6, from Cape Canaveral Air Force Station in Florida, two University of California, Berkeley, astronomers - key members of the Kepler team - will be watching its fading contrail, hoping that the telescope will reveal Earth's and humanity's place in the universe.
NASA's Kepler spacecraft is ready to be moved to the launch pad today and will soon begin a journey to search for worlds that could potentially host life.
WASHINGTON, Feb. 19 /PRNewswire-USNewswire/ -- NASA's Kepler spacecraft is ready to be moved to the launch pad today and will soon begin a journey to search for worlds that could potentially host life.
The European Space Agency says the COROT space telescope has found the smallest terrestrial planet ever detected outside the solar system. The ESA said the newly discovered exoplanet is less than twice the size of Earth and orbits a sun-like star.
A team of University of Hertfordshire astronomers led by Dr David Pinfield of the Centre for Astrophysics Research is leading a major new European collaboration to search for and study planets around other stars (extra-solar planets).
Astronomers have turned to an unexpected place to study the evolution of planets -- dead stars.
Planetary and Space Science is a peer-reviewed scientific journal established in 1959 and published by Elsevier 15 times per year. As of May 2012, the editor-in-chief is Rita Schulz (The Netherlands). The journal publishes original research articles and short communications. The main focus is on solar system processes which encompass multiple areas of the natural sciences. Research that involves planetary and space sciences involves many disciplines. Celestial mechanics is part of these...
Terrestrial Planet Finder -- The Terrestrial Planet Finder is a proposed NASA telescope system capable of detecting extrasolar terrestrial planets. In May 2002, NASA chose two TPF mission architecture concepts for further study and technology development. Each would use a different means to achieve the same goal - to block the light from a parent star in order to see its much smaller, dimmer planets. That technology challenge has been likened to finding a firefly near the beam of...
Planet -- A planet is a body of considerable mass that orbits a star and that doesn't produce energy through nuclear fusion. Until recently, only nine were known (all of them in our own Solar system). As of the end of 2002 over 100 are known, with all of the new discoveries being extrasolar planets. Astronomers often call asteroids minor planets, and call the larger planetary bodies (those which are commonly called planets) major planets. Planets within the solar system can be...
Gas Giant -- A gas giant is a generic astronomical term invented by the science fiction writer James Blish to describe any large planet that is not composed mostly of rock or other solid matter. Gas giants may still have a solid core - in fact, it is expected that such a core is probably required for a gas giant to form - but the majority of its mass is in the form of gas (or gas compressed into a liquid state). Unlike rocky planets, gas giants do not have a well-defined surface. There...
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...
