Hot Topic Solar System Meteorites, Comets and Asteroids
 
Team Stardust
Topic: Meteorites, Comets and Asteroids
05/20/06
During the first week in May, representatives of each of the six Stardust sub-teams met to discuss the state of their findings and began outlining the research papers that they will submit for publication this summer. The three day workshop was held at the Timber Cove Inn, a remote seaside location north of San Francisco.

Like interplanetary spaceship carrying passengers, meteorites have long been suspected of ferrying relatively young ingredients of life to our planet. Using new techniques, scientists have discovered that meteorites can carry much older passengers that originated billions of years ago.

Contemplating Craters
Topic: Meteorites, Comets and Asteroids
05/04/06
In this interview, Charles Cockell and Simon Mitton discuss the awesome experience of standing at the edge of an impact crater. The explosive force of a large asteroid impact would kill anyone unlucky enough to be nearby, and craters they leave behind can serve as a reminder for dangers that still lurk in our solar system.

Cometary Crack Up
Topic: Meteorites, Comets and Asteroids
04/29/06
The NASA/ESA Hubble Space Telescope is providing astronomers with extraordinary views of comet 73P/Schwassmann-Wachmann 3 as it disintegrates before our eyes. Recent Hubble images have uncovered many more fragments than have been reported by ground-based observers.

The Art of Asteroid Avoidance
Topic: Meteorites, Comets and Asteroids
04/25/06
Over the last few decades there has been a great deal of debate about the level of danger posed by impacts from asteroids and comets. It appears the world needs to take the threat of asteroid strikes a lot more seriously.

Daughters of Deep Impact
Topic: Meteorites, Comets and Asteroids

Over the past five years, three space missions -- Deep Impact, Deep Space 1 and Stardust -- have provided unprecedented information about comets.

Deflecting Don Quijote
Topic: Meteorites, Comets and Asteroids
04/08/06
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. As part of ESA s Near-Earth Object deflecting mission Don Quijote, three teams of European industries are now carrying out studies on how to prevent this.

The 250,000 Ton Punch
Topic: Meteorites, Comets and Asteroids
04/04/06
Over the weekend of 9-10 July 2005 a team of UK and US scientists, led by Dr. Dick Willingale of the University of Leicester, used NASAE28099s Swift satellite to observe the collision of NASA's Deep Impact spacecraft with comet Tempel 1. The Swift observations show that the comet grew brighter and brighter in X-ray light after the impact, with the X-ray outburst lasting a total of 12 days.

Life in Tiny Tunnels?
Topic: Meteorites, Comets and Asteroids
03/26/06
A new study of a meteorite that originated from Mars has revealed a series of microscopic tunnels that are similar in size, shape and distribution to tracks left on Earth rocks by feeding bacteria.

Are We Drinking Comet Water?
