Hot Topic Solar System Meteorites, Comets and Asteroids
 
Will Comet ISON Survive Its Brush with the Sun?
Topic: Meteorites, Comets and Asteroids
10/15/13
A new study examines comet ISON’s chances of surviving its close pass of the Sun. Studying how the Sun affects ISON can help astrobiologists learn about its physical properties.

Chelyabinsk Fireball Provides Insight into Space Collisions
Topic: Meteorites, Comets and Asteroids
10/14/13
Scientists have reported new findings on meteorites that were recovered after the Chelyabinsk fireball that exploded over Russia earlier this year.

Telescopes Team up to Study Triple Asteroid
Topic: Meteorites, Comets and Asteroids
10/09/13
By combining observations from amateur astronomers and large telescopes, astronomers have uncovered valuable data about the complex interior of the asteroid (87) Sylvia.

First Evidence of a Comet Striking Earth
Topic: Meteorites, Comets and Asteroids
10/09/13
For the first time ever, scientists have positively identified cometary material that fell to Earth long ago. The study is the first proof a comet striking Earth, and will help astrobiologists study these unique celestial bodies and their role in our solar system's formation.

A New Look at Creating the Seeds of Life in Asteroids
Topic: Meteorites, Comets and Asteroids
10/05/13
Scientists have introduced an new theory explaining how biomolecules could have been formed inside of asteroids in the early Solar System.

A Vesta Reality Check
Topic: Meteorites, Comets and Asteroids
10/02/13
Close-up views of Vesta from NASA's Dawn spacecraft are helping scientists better interpret Earth-based observations of the giant asteroid.

Comet Impacts Create Ingredients of Life
Topic: Meteorites, Comets and Asteroids
09/21/13
Scientists have created a number of amino acids by shock compressing an icy mixture similar to the materials found in comets. The study supports the idea that life's building blocks could have come to Earth from space.

Unexpected Organics in Sutter's Mill Meteorite
Topic: Meteorites, Comets and Asteroids
09/15/13
The Sutter's Mill meteorite, which exploded over California last year, is providing important information about the inventory of molecules that could have been delivered from space to the early Earth.

Two Asteroids Found to be Comets
Topic: Meteorites, Comets and Asteroids
09/14/13
Two different teams are reporting that what scientists long thought were asteroids are actually comets.

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.
