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)
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)
UK pupils scan the skies for hazardous asteroids
Tracking newly discovered asteroids and comets to identify their orbits is the work of a small number of observatories. Yet UK students, using the Faulkes Telescope North - a remotely operated research quality telescope dedicated for educational use - will now be swelling these ranks. The students have taken such accurate data of a number of... view more... (2004-10-06)
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)
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)
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)
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)
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)
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)
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)
UMd-led team finds ancient asteroids formed at solar system's start
Using visible and infrared data collected from telescopes on Hawaii's Mauna Kea, a team of scientists, led by the University of Maryland's Jessica Sunshine, have identified three asteroids that appear to be among our Solar System's oldest objects. view more (2008-03-24)
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)
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)
Dealing with threatening space rocks
Every now and then a space rock hits the world's media - sometimes almost literally. Threatening asteroids that zoom past the Earth, fireballs in the sky seen by hundreds of people and mysterious craters which may have been caused by impacting meteorites; all make ESA's activities in this field, including the Don Quijote study, look increasingly... view more...

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)
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)
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)
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)
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)
Primitive asteroids in the main asteroid belt may have formed far from the sun
Many of the objects found today in the asteroid belt located between the orbits of Mars and Jupiter may have formed in the outermost reaches of the solar system. view more (2009-07-16)
