Mysterious carbon excess found in infant solar system
Astronomers detected unusually high quantities of carbon, the basis of all terrestrial life, in an infant solar system around nearby star Beta Pictoris, 63 light-years away. view more (2006-06-08)
UK Astronomers Watch the Skies for Threat from Space
British astronomers are providing a vital component to the world-wide effort of identifying and monitoring rogue asteroids and comets. From this month, the UK Astrometry and Photometry Programme (UKAPP) for Near-Earth Objects, based at Queens University, Belfast, will track Near-Earth Objects (NEOs) and feed their crucial information into the... view more...

Half-baked asteroids have Earth-like crust
Asteroids are hunks of rock that orbit in the outer reaches of space, and scientists have generally assumed that their small size limited the types of rock that could form in their crusts. view more (2009-01-08)
Did comets flood Earth's oceans?
Did the Earth form with water locked into its rocks, which then gradually leaked out over millions of years? Or did the occasional impacting comet provide the Earth's oceans? The Ptolemy experiment on Rosetta may just find out"¦ The Earth needed a supply of water for its oceans, and the comets are large celestial icebergs - frozen... view more... (2004-06-16)
First triple asteroid system found
One of the thousands of asteroids orbiting the sun has been found to have a mini planetary system of its own. view more (2005-08-11)
Light Gives Asteroids Spin
Astronomers have observed an asteroid change the rate at which it spins for the first time, and shown that this is due to a theoretical effect predicted but never before seen view more (2007-03-12)
UK astronomers observe asteroid before it crashes into Earth
UK astronomers, using the Science and Technology Facilities Council's (STFC) William Herschel Telescope on La Palma, observed a rare asteroid as it was hurtling towards our planet and have captured the only spectrum of it before it exploded in our atmosphere. view more (2009-03-27)
Freshly painted Arecibo Observatory returns to work, spies object associated with meteor showers
After receiving its first fresh, full coat of paint in more than 40 years, Arecibo Observatory made its first observation in more than six months at 6:36 a.m., Saturday, Dec. 8. view more (2007-12-26)
Royal Astronomical Society Debates Asteroid Threat 14 December
Action being taken by the UK government, the United Nations and the European Space Agency to further our understanding of the hazard posed by near Earth objects (NEOs) in space are on the agenda at Royal Astronomical Society meetings in London on Friday 14 December. The meetings are open and media representatives are cordially invited. (For... view more... (2001-12-09)
Contrary to recent hypothesis, 'chevrons' are not evidence of megatsunamis
A persistent school of thought in recent years has held that so-called "chevrons," large U- or V-shaped formations found in some of the world's coastal areas, are evidence of megatsunamis caused by asteroids or comets slamming into the ocean. view more (2009-04-29)
Asteroids: treasures of the past and a threat to the future
If a large asteroid such as the recently identified 2004 VD17 - about 500 m in diameter with a mass of nearly 1000 million tonnes-collides with the Earth it could spell disaster for much of our planet. view more (2006-04-04)
Life And Death In Space
Ever since its formation at the birth of the Solar System, some 4570 million years ago, planet Earth has resembled a giant bulls-eye in space, a target for asteroids and comets of all shapes and sizes. Clearly, this violent history has influenced the planet's surface and atmosphere, as well as the evolution of life. Some impactors bring water and... view more... (2003-04-05)
Amateurs and professionals combine observations to produce detailed picture of double asteroid
Roping together observations from the world's largest telescopes as well as the small instrument of a local backyard amateur, astronomers have assembled the most complete picture yet of a pair of asteroids whirling around one another in a perpetual pas de deux. view more (2007-03-30)
Binary asteroid in Jupiter's orbit may be icy comets from solar system's infancy
Astronomers at the University of California, Berkeley, working with colleagues in France and at the Keck Telescope in Hawaii, have calculated the density of a known binary asteroid system that shares Jupiter's orbit, and concluded that Patroclus and its companion probably are composed mostly of water ice covered by a patina of dirt. view more (2006-02-02)
Dust-enshrouded star looks similar to our sun
Astronomers report tremendous quantities of warm dusty debris surrounding a star with luminosity and mass similar to the sun's, but located 300 light-years from Earth. view more (2005-07-21)
Study highlights role of hit-and-run collisions in planet formation
Hit-and-run collisions between embryonic planets during a critical period in the early history of the Solar System may account for some previously unexplained properties of planets, asteroids, and meteorites. view more (2006-01-12)
Engineering researcher seeks answers to asteroid deflection
An Asteroid Deflection Research Center (ADRC) has been established on the Iowa State campus to bring researchers from around the world to develop asteroid deflection technologies. The center was signed into effect in April by the Office of the Executive Vice President and Provost. view more (2008-05-28)
2 unusual older stars giving birth to second wave of planets
Hundreds of millions - or even billions - of years after planets would have initially formed around two unusual stars, a second wave of planetesimal and planet formation appears to be taking place, UCLA astronomers and colleagues believe. view more (2008-01-10)
A Curious Pair of Galaxies
The ESO Very Large Telescope has taken the best image ever of a strange and chaotic duo of interwoven galaxies. The images also contain some surprises - interlopers both far and near. view more (2009-03-17)
APL Astronomer Spies Conditions 'Just Right' for Building an Earth
An Earth-like planet is likely forming 424 light-years away in a star system called HD 113766, say astronomers using NASA's Spitzer Space Telescope. view more (2007-10-04)
