Rosetta closes in on Earth - a second time
ESA's comet chaser, Rosetta, is on its way to its second close encounter with Earth on 13 November. The spacecraft's operators are leaving no stones unturned to make sure Earth's gravity gives it the exact boost it needs en route to its destination. view more (2007-11-09)
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)
Avoiding the fate of the dinosaurs
Tales of asteroids or comets in a collision course with the Earth are always good to fill space in newspapers during the quiet summer months. Is there any truth in these tales of impending doom and if so, what is ESA doing about it? Certainly if a large comet or asteroid were to collide with the Earth the result could be apocalyptic. But the... view more... (2002-09-25)
No need to thank dinosaur-killing asteroid for mammalian success
It is a natural history tale that every third grader knows: The dinosaurs ruled the Earth for hundreds of millions of years, until an asteroid struck the Yucatan Peninsula and triggered a mass extinction that allowed the ancestors of today's mammals to thrive. view more (2007-03-29)
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)
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)
Space Technology Centre opens at University of Dundee
Lord Sainsbury, UK Minister for Science and Innovation will officially open the University of Dundee's new Space Technology Centre that will carry out advanced research into planetary landing simulators and develop support technology for many space missions. view more (2005-03-17)
Creating a better transmission system for deep-space applications
Recent advances in wireless computing technology could improve deep-space missions like asteroid research and remote spacecraft operations by changing the way signals are sent from Earth. view more (2005-10-25)
We Owe It All to Comets
Comets have always fascinated us. A mysterious appearance could symbolize God's displeasure or mean a sure failure in battle, at least for one side. view more (2009-04-29)
Princeton geoscientist offers new evidence that meteorite did not wipe out dinosaurs
A Princeton University geoscientist who has stirred controversy with her studies challenging a popular theory that an asteroid wiped out the dinosaurs has compiled powerful new evidence asserting her position. view more (2009-05-05)
Caribbean Frogs Started with a Single, Ancient Voyage on a Raft from South America
Nearly all of the 162 land-breeding frog species on Caribbean islands, including the coqui frogs of Puerto Rico, originated from a single frog species that rafted on a sea voyage from South America about 30-to-50-million years ago. view more (2007-06-07)
Follow Rosetta's final Earth boost
ESA's comet chaser Rosetta will swing by Earth for the last time on 13 November to pick up energy and begin the final leg of its 10-year journey to comet 67P/Churyumov-Gerasimenko. ESA's European Space Operations Centre will host a media briefing on that day. view more (2009-11-05)
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)
Tunguska catastrophe: Evidence of acid rain supports meteorite theory
The Tunguska event is regarded as one of the biggest natural disasters of modern times. On 30 June 1908 one or more explosions took place in the area close to the Tunguska River north of Lake Baikal. The explosion(s) flattened around 80 million trees over an area of more than 2000 square kilometres. view more (2008-07-16)
Study unravels why certain fishes went extinct 65 million years ago
Large size and a fast bite spelled doom for bony fishes during the last mass extinction 65 million years ago, according to a new study to be published March 31, 2009, in the Proceedings of the National Academy of Sciences. view more (2009-03-27)
Extraterrestrial Impact Likely Source of Sudden Ice Age Extinctions
At the end of the Pleistocene era, wooly mammoths roamed North America along with a cast of fantastic creatures - giant sloths, saber-toothed cats, camels, lions, tapirs and the incredible teratorn, a condor with a 16-foot wingspan. view more (2007-09-25)
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)
Hubble captures rare Jupiter collision
The checkout and calibration of the NASA/ESA Hubble Space Telescope has been interrupted to aim the recently refurbished observatory at a new expanding spot on the giant planet Jupiter. view more (2009-07-27)

Something slammed into Jupiter in the last few days, creating a dark bruise about the size of the Pacific Ocean. view more (2009-07-22)
Asteroid attack 3.9 billion years ago may have enhanced early life on Earth, says CU-Boulder study
The bombardment of Earth nearly 4 billion years ago by asteroids as large as Kansas would not have had the firepower to extinguish potential early life on the planet and may even have given it a boost, says a new University of Colorado at Boulder study. view more (2009-05-21)
