Scientists find a solar-powered asteroid
An international research team led by Academy Research Fellow Mikko Kaasalainen has found an asteroid whose rotation receives an extra kick from solar radiation. view more (2007-03-08)
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)
Insect attack may have finished off dinosaurs
Asteroid impacts or massive volcanic flows might have occurred around the time dinosaurs became extinct, but a new book argues that the mightiest creatures the world has ever known may have been brought down by a tiny, much less dramatic force - biting, disease-carrying insects. view more (2008-01-03)
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)
Science Team Determines Composition of Asteroid Itokawa
Itokawa, a spud-shaped, near-Earth asteroid, consists mainly of the minerals olivine and pyroxene, a mineral composition similar to a class of stony meteorites that have pelted Earth in the past. view more (2006-06-02)
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)
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)
Seismic images show dinosaur-killing meteor made bigger splash
The most detailed three-dimensional seismic images yet of the Chicxulub crater, a mostly submerged and buried impact crater on the Mexico coast, may modify a theory explaining the extinction of 70 percent of life on Earth 65 million years ago. view more (2008-01-24)
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)
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)
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)
First detailed pictures of asteroid reveal bizarre system
The first detailed images of a binary asteroid system reveal a bizarre world where the highest points on the surface are actually the lowest, and the two asteroids dance in each other's gravitational pull. view more (2006-10-13)
Planets forming in Pleiades star cluster, astronomers report
Rocky terrestrial planets, perhaps like Earth, Mars or Venus, appear to be forming or to have recently formed around a star in the Pleiades ("seven sisters") star cluster, the result of "monster collisions" of planets or planetary embryos. view more (2007-11-16)
Saturn's rings have own atmosphere
Data from the NASA/ESA/ASI Cassini spacecraft indicate that Saturn's majestic ring system has its own atmosphere-separate from that of the planet itself. view more (2005-08-18)
UAF geologist studies Chicxulub impact crater
About 65 million years ago, a massive disruption led to worldwide extinction of dinosaurs. The impact of a giant asteroid created massive tsunamis and spewed forth a global cloud of carbon gases that altered Earth's atmosphere and blocked the light for weeks, possibly years. In recent years, that impact event has been linked to a 112-mile-wide... view more... (2007-01-19)
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)
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)
Floating pile of rubble a pristine record of solar system's history
A small, near-Earth asteroid named Itokawa is just a pile of floating rubble, probably created from the breakup of an ancient planet, according to a University of Michigan researcher was part of the Japanese space mission Hayabusa. view more (2006-06-02)
Rosetta warms up for Mars swing-by
This month the team working on ESA's Rosetta mission have been particularly busy. Activities are underway to set the spacecraft's trajectory and prepare the on-board instruments ready for the next major mission milestone: the swing-by of planet Mars in February 2007. view more (2006-11-30)
University of Western Ontario cameras capture 'fireball'
For the second time this year, The University of Western Ontario Meteor Group has captured incredibly rare video footage of a meteor falling to Earth. The team of astronomers suspects the fireball dropped meteorites in a region north of Guelph, Ontario, Canada, that may total as much as a few hundred grams in mass. view more (2008-10-27)
