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)
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)
Record: fastest flashing star
Dutch researcher Steve van Straaten set a record during his doctoral research. The researcher registered the fastest ever change in the X-ray emission originating from a binary star. The record-breaking binary star consists of a neutron star and a lighter companion star. Astronomer Steve van Straaten studied the time variations in the X-ray... view more... (2004-05-07)
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)
AKARI's observations of asteroid Itokawa
The space-borne infrared observatory AKARI, observed asteroid Itokawa last month with its Infrared Camera. The data will be used to refine estimates of sizes of potentially hazardous asteroids in the future. view more (2007-08-24)
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)
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)
How to deflect asteroids and save the Earth
You may want to thank David French in advance. Because, in the event that a comet or asteroid comes hurtling toward Earth, he may be the guy responsible for saving the entire planet. view more (2009-04-17)
A UK Flotilla To Study Earth-Grazing Asteroids
On 30 June 1908, the seemingly endless forests of Siberia received an unwelcome and unexpected visit by an intruder from deep space. As it plunged headlong through the Earth's atmosphere, the incoming asteroid exploded a few miles above the tree tops, flattening the forest over an area about 50 km (30 miles) in diameter. If the 60 metre (200 ft)... view more... (2003-04-01)
New Star Systems First of Their Kind
Researchers funded by the National Science Foundation (NSF) announced today in Astrophysical Journal Letters that they have discovered a faraway binary star system that could be the progenitor of a rare type of supernova. view more (2008-04-02)
A sharper look at near Earth asteroid 2002 NY40
The Near Earth Asteroid 2002 NY40 was observed with the William Herschel Telescope on La Palma, Canary Islands, on the night of August 17 to 18, 2002. The asteroid was imaged just before its closest approach to Earth, using the Adaptive Optics system NAOMI. These are the first images of a Near Earth Asteroid obtained with an Adaptive Optics... view more... (2002-09-03)
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)
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)
How to deflect an asteroid
STRANGE as it may seem, averting Armageddon isn`t the top priority for most asteroid hunters. They`d be happy just to know where the rock that could wipe out life on Earth will come from. But an astronomer in Italy thinks he can save the world-with space-based missiles. By the end of the decade,... view more... (2002-02-13)
How to Destroy an Asteroid
In the hit 1998 movie Armageddon, Bruce Willis and Ben Affleck blew up an asteroid to save the world. While the film was science fiction, the chances of an asteroid hitting the Earth one day are very real ― and blowing up an asteroid in real life. view more (2008-12-04)
Discovery of the source of the most common meteorites
When observing with the GEMINI telescopes, two astronomers from Brazil and the United States discovered for the first time asteroids that are similar to "ordinary chondrites", the most common meteorites found on Earth. Until now, astronomers have failed to identify their asteroidal sources because of the various geologic processes that... view more... (2008-07-11)
Nullarbor fireball cameras find rare meteorite
Using cameras which capture fireballs streaking across the night sky and sophisticated mathematics, a world-wide team of scientists have managed to find not only a tiny meteorite on the vast Nullarbor Plain, but also its orbit and the asteroid it came from. view more (2009-09-18)
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)
Solar wind tans young asteroids
A new study published in Nature this week reveals that asteroid surfaces age and redden much faster than previously thought -- in less than a million years, the blink of an eye for an asteroid. This study has finally confirmed that the solar wind is the most likely cause of very rapid space weathering in asteroids. This fundamental result will... view more... (2009-04-23)
University of Hawaii at Manoa astronomers discover pair of solar systems in the making
Two University of Hawai'i at Mānoa astronomers have found a binary star-disk system in which each star is surrounded by the kind of dust disk that is frequently the precursor of a planetary system. view more (2009-07-01)
