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)
New comet discovered in Canada
Rob Cardinal was looking for an asteroid, but ended up finding a comet. It is the first time a comet has been discovered at the University of Calgary's Rothney Astrophysical Observatory, which is located about 35 kilometres southwest of Calgary, and only the second Canadian discovery of a comet using a Canadian telescope in nearly a decade. view more (2008-10-15)
We saw it coming: Asteroid monitored from outer space to ground impact
Reports by scientists of meteorites striking Earth in the past have resembled police reports of so many muggings - the offenders came out of nowhere and then disappeared into the crowd, making it difficult to get more than very basic facts. view more (2009-03-26)
European Space Agency to probe asteroid blind spot
In the past five weeks two asteroids have passed close by Earth, at distances of 1.2 and 3 times the distance to the Moon. Another asteroid has recently been shown to be on course for a collision with Earth in 2880. Monitoring known asteroids allows astronomers to predict which may collide with Earth. But that is only true for the asteroids we... view more... (2002-04-15)
Planets like earth may have formed around other stars, UCLA astronomers report
The chemical fingerprint of a burned-out star indicates that Earth-like planets may not be rare in the universe and could give clues to what our solar system will look like when our sun dies and becomes a white dwarf star some five billion years from now. view more (2007-08-20)
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)
Asteroids and meteorites reveal family resemblance
Asteroids and meteorites are supposed to be made of the same stuff - at least that's what earth science teachers have been telling their students for decades. view more (2006-09-11)
Asteroid Hunting
A lot of attention has been paid in recent years to the asteroid threat issue. The International Asteroid Patrol has been set up to monitor the flight of potentially dangerous celestial rocks in visual diapason. However, the accuracy of optical methods for determining the trajectory leaves much to be desired. That accounts for inaccuracy of... view more... (2003-03-07)
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)
New study reveals twice as many asteroids as previously believed
Asteroids in our Solar System may be more numerous than previously thought, according to the first systematic search for these objects performed in the infrared, with ESA`s Infrared Space Observatory, ISO. The ISO Deep Asteroid Search indicates that there are between 1.1 million and 1.9 million `space rocks` larger than 1 kilometre in diameter in... view more... (2002-04-05)
A world ruled by fungi
The catastrophe that extinguished the dinosaurs and other animal species, 65 million years ago also brought dramatic changes to the vegetation. In a study presented in latest issue of the journal Science, the paleontologists Vivi Vajda from the University of Lund, Sweden and Stephen McLoughlin from the Queensland University of Technology,... view more...

Cosmic connections: Imperial scientist locates the origin of cosmic dust
The research, published in the journal Geology, shows that some of the cosmic dust falling to Earth comes from an ancient asteroid belt between Jupiter and Mars. This research improves our knowledge of the solar system, and could provide a new and inexpensive method for understanding space. view more (2008-09-03)
Burning asteroids may play 'more important climate role than previously recognized'
Dust from asteroids entering the atmosphere may influence Earth's weather more than previously believed, researchers have found. view more (2005-08-26)
Extinction by asteroid a rarity
In geology as in cancer research, the silver bullet theory always gets the headlines and nearly always turns out to be wrong. view more (2008-10-07)
65-million-year-old asteroid impact triggered a global hail of carbon beads
The asteroid presumed to have wiped out the dinosaurs struck the Earth with such force that carbon deep in the Earth's crust liquefied, rocketed skyward, and formed tiny airborne beads that blanketed the planet. view more (2008-05-06)
Saturn's rings show evidence of a modern-day collision
Scientists on NASA's Cassini mission have spied a new, continuously changing feature that provides circumstantial evidence that a comet or asteroid recently collided with Saturn's innermost ring, the faint D ring. view more (2006-10-12)
Intensive statin therapy may partially reverse plaque build-up in arteries
A study presented today at the American College of Cardiology's 55th Annual Scientific Session demonstrates, for the first time, that very intensive cholesterol lowering with a statin drug can regress (partially reverse) the buildup of plaque in the coronary arteries. view more (2006-03-14)
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)
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)
Three new 'Trojan' asteroids found sharing Neptune's orbit
Three new objects locked into roughly the same orbit as Neptune—called "Trojan" asteroids—have been found by researchers from the Carnegie Institution's Department of Terrestrial Magnetism (DTM) and the Gemini Observatory in Hilo, Hawaii. view more (2006-06-16)
