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. Kepler is scheduled to blast into space from Cape Canaveral Air Force Station, Fla., aboard a Delta II rocket on March 5 at 10:48 p.m. EST. It is the first mission with the ability to find planets like Earth -- rocky planets that orbit sun-like stars in a warm zone where liquid water could be maintained on the surface. Liquid water is...

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. Its temperature is so high -- approximately 2,000 degrees or more Fahrenheit -- it is possibly covered in lava or water vapor. This discovery is a very important step on the road to understanding the formation and evolution of our planet, said...

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). Funded with £2.75 million from the European Commission, this research and technology network will focus on the search for rocky planets around cool stars and the development of future space-based technology to study extra-solar planets. Cool stars are much...

Astronomers have turned to an unexpected place to study the evolution of planets -- dead stars. Observations made with NASA's Spitzer Space Telescope reveal six dead "white dwarf" stars littered with the remains of shredded asteroids. This might sound pretty bleak, but it turns out the chewed-up asteroids are teaching astronomers about the building materials of planets around other stars. So far, the results suggest that the same materials that make up Earth and our solar system's other rocky...

Moons outside our solar system with the potential to support life have just become much easier to detect, thanks to research by an astronomer at University College London (UCL). David Kipping, whose work is funded by the UK's Science and Technology Facilities Council (STFC), has found that such moons can be revealed by looking at wobbles in the velocity of the planets they orbit. His calculations, which appear in the Monthly Notices of the Royal Astronomical Society today (11th December), not...

The U.S. space agency says its Hubble Space Telescope has discovered carbon dioxide in the atmosphere of a planet orbiting another star. The National Aeronautics and Space Administration said the discovery is an important step toward finding chemical biotracers of extraterrestrial life. Although the extrasolar, Jupiter-sized planet called HD 189733b is too hot for life, NASA said the Hubble observations are a proof-of-concept demonstration that the basic chemistry for life can be measured on...

NASA's Hubble Space Telescope has discovered carbon dioxide in the atmosphere of a planet orbiting another star. This is an important step along the trail of finding the chemical biotracers of extraterrestrial life as we know it. The Jupiter-sized planet, called HD 189733b, is too hot for life. But the Hubble observations are a proof-of-concept demonstration that the basic chemistry for life can be measured on planets orbiting other stars. Organic compounds can also be a by-product of life...

A team of astronomers from Penn State and Nicolaus Copernicus University in Poland has discovered a new planet that is closely orbiting a red-giant star, HD 102272, which is much older than our own Sun. The planet has a mass that is nearly six times that of Jupiter, the largest planet in our solar system. The team includes Alexander Wolszczan, the discoverer of the first planets ever found outside our solar system, who is an Evan Pugh Professor of Astronomy and Astrophysics and the director...

Two teams of astronomers have captured the first images of a distant solar system that appears to be orbiting a star. The images show three planets orbiting a star named HR8799, which is 140 light years away and about 1.5 times the size of our sun. The fourth gaseous planet orbits a separate star. The three planets in orbit around HR8799 range in size from five to 13 times the mass of Jupiter and are probably only about 60 million years old. They decrease in size away from the parent star in...

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

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...
