Hot Topic Solar System Meteorites, Comets and Asteroids
 
Finding Our Origin in a Meteorite
Topic: Meteorites, Comets and Asteroids
12/03/06
NASA researchers have found organic materials that formed in the early Solar System preserved in the freshest meteorite ever received from space. Organic matter in meteorites is of intense interest because this material may have seeded the early Earth with the building blocks of life.

KW4 Keeping its Distance, For Now
Topic: Meteorites, Comets and Asteroids
11/19/06
The Arecibo Observatory has made new observations of a binary near-Earth asteroid named KW4. Studying the formation and evolution of such near-Earth asteroids helps researchers learn how to mitigate the potential threat they pose to Earth. KW4 is classified as a Potentially Hazardous Asteroid, but data show that its path will not intersect Earth's for at least 1,000 years.

Meteorites: Friend or Foe?
Topic: Meteorites, Comets and Asteroids
11/09/06
In this interview, Monica Grady discusses the varieties of dust and meteorites that have fallen to Earth, and explains what they tell us about the history of the solar system and its potential for life.

Seeking Out Meteorites
Topic: Meteorites, Comets and Asteroids
11/06/06
In this interview, Monica Grady talks about hunting for meteorites on the moon in order to learn more about the ancient Earth. She also explains why it took so long for us to find a meteorite originating from Mars.

The Astrobiology Connection
Topic: Meteorites, Comets and Asteroids
11/01/06
Welcome to Radio Astrobiology, the podcast of Astrobiology Magazine. Join us as David Grinspoon investigates a mystery at the bottom of the Earth, and explains what it might mean for the possibility for life elsewhere in the solar system.

Seeing Ourselves in Comets
Topic: Meteorites, Comets and Asteroids
08/04/06
Evidence of atomic nitrogen in interstellar gas clouds suggests that pre-life molecules may be present in comets, a discovery that gives a clue about the early conditions that gave rise to life, according to researchers from the University of Michigan and the Harvard-Smithsonian Center for Astrophysics.

Seeing Comets Clearly
Topic: Meteorites, Comets and Asteroids
07/17/06
Scientists are getting their best understanding yet of the makeup of comets - not only of the materials inside these planetary building blocks, but also of the way they could have formed around the Sun in the solar system's earliest years.

Arctic, Antarctic, Mars
Topic: Meteorites, Comets and Asteroids
06/19/06
When scientists examined a meteorite from Mars under a microscope, they discovered tiny mineral spheres that, some argued, were produced by living organisms. Now, researchers working in the high Arctic have found similar mineral features, produced not by microbes, but by a volcano.

Finding a Rock that Knocked
Topic: Meteorites, Comets and Asteroids
06/18/06
Scientists have found a chunk of a meteorite that made an enormous impact crater in South Africa 146 million years ago. Found half a mile down, the chrondritic meteorite somehow survived the shock pressures and temperatures of the immense impact. Fossil meteorites have previously been found in craters.

Itokawa Rubble Pile
Topic: Meteorites, Comets and Asteroids
06/06/06
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 that was part of the Japanese space mission Hayabusa.
