Hot Topic Solar System Meteorites, Comets and Asteroids
 
Rosetta Spacecraft Waking Up for Final Leg of Comet Landing
Topic: Meteorites, Comets and Asteroids
01/20/14
Rosetta will be the first to orbit and land a probe on a comet.

Organics Preserved in Ancient Meteorite-Formed Glass
Topic: Meteorites, Comets and Asteroids
12/16/13
Scientists have found organics from Earth's swamp trapped inside glass that had been created by a meteor impact almost a million years ago.

Ice on Ceres: 'An Interesting Paradox'
Topic: Meteorites, Comets and Asteroids
12/05/13
Indications that ice makes up a third of the mass of Ceres may make the dwarf planet the most easily explored icy body -- and NASA's Dawn mission is on its way there now.

A Crater as an Abode for Life
Topic: Meteorites, Comets and Asteroids
11/01/13
A new study shows how the heat generated from an asteroid impact could lead to a crater becoming a refuge for life, or even a potential birthplace for life’s origin.

Defending the Earth From Asteroids
Topic: Meteorites, Comets and Asteroids
10/26/13
In a recent event at the American Museum of Natural History in New York City, astronauts and cosmonauts who have flown for three different space agencies (United States, Russia, and Japan) discussed asteroid detection and deflection.

Meteorite Minerals Hint at Earth Extinctions, Climate Change
Topic: Meteorites, Comets and Asteroids
09/12/13
Tiny minerals leftover from many small meteorites could provide the geological evidence needed to show how rocks falling from the sky often changed the course of life’s evolution on Earth.

Dwarf Planet Ceres – 'A Game Changer in the Solar System'
Topic: Meteorites, Comets and Asteroids
08/28/13
When NASA's Dawn mission investigates the potentially icy dwarf planet Ceres, it may find more than originally expected. The closest frozen body to Earth, Ceres may be as promising when it comes to hosting life than the more distant moons of the gas giants.

Impacts Could be Boon for Subterranean Life
Topic: Meteorites, Comets and Asteroids
04/16/12
A drilling project into the Chesapeake Bay impact crater has found evidence that the subsurface may become more habitable after a large impact.

Close Encounter with Comet Hartley 2
Topic: Meteorites, Comets and Asteroids
11/05/10
NASA's EPOXI spacecraft flew by comet Hartley 2, and the images it captured show a peanut-shaped nucleus with many jets of gas spewing from its surface. Studying comets like Hartley 2 can help astrobiologists determine if comets played a role in the origin of life on Earth.

The Impact that Shattered Santa Fe
Topic: Meteorites, Comets and Asteroids
08/09/10
A large meteorite impact can have a profound effect on life. The explosive force is often compared to a nuclear detonation, and the debris tossed high into the atmosphere can alter our planet´s climate. In the mountains of New Mexico, scientists have found evidence for an ancient meteorite strike -- even though the impact crater is long gone.
