Watch the Video: Hydrogen Hot Spots on Vesta Lee Rannals for redOrbit.com - Your Universe Online According to findings reported in the journal Science, NASA's Dawn spacecraft has revealed signs of hydrated minerals on the giant asteroid Vesta. Dawn did not find actual water ice at Vesta, but it did reveal signs of hydrated minerals delivered by meteorites and dust to the asteroid. "The source of the hydrogen within Vesta's surface appears to be hydrated minerals delivered by...

Supernova Shock Wave And Its Role In Solar System Formation
2012-08-03 09:04:16

April Flowers for redOrbit.com - Your Universe Online It has long been thought that our Solar System was formed by the shockwave from a supernova explosion. According to this theory, the shockwave also injected material from the exploding star into a cloud of gas and dust. The newly polluted cloud formed the Sun and its surrounding planets. A new study by Alan Boss and Sandra Keiser of the Carnegie Institution for Science, published in The Astrophysical Journal Letters, provides the...

Tagish Lake Meteorites Help Solve Amino Acid Mysteries
2012-07-26 14:48:28

Lee Rannals for redOrbit.com - Your Universe Online New clues have been unveiled that shed light on why living things use only molecules with specific orientations. Research analyzing meteorite fragments that fell on a frozen lake in Canada is providing strong evidence that liquid water inside an asteroid leads to a preference of left-handed over right-handed forms of common protein amino acids in meteorites. "Our analysis of the amino acids in meteorite fragments from Tagish Lake...

Puzzling Science: Answering Questions About Comets And Asteroids

Lee Rannals for redOrbit.com - Your Universe Online Astronomers have started to answer questions about two unsolved puzzles about the building blocks of our Solar System. Two questions that have puzzled scientists about comets and asteroids are: How did icy comets obtain particles that formed at high temperatures? And, how did these refractory particles acquire rims with different compositions? Researchers from Carnegie Institution for Science have modeled the trajectories of these...

Meteorites Hold Secrets Of Earth's Formation

Crater -- A crater is a circular depression on the surface of a planet, moon, asteroid, or other celestial body. Craters are typically caused by meteorite impacts, although some are caused by volcanic activity. In the center of craters on Earth a crater lake often accumulates, and in craters formed by meteorites a central island (caused by rebounding crustal rock after the impact) is usually a prominent feature in the lake. Ancient craters whose relief has disappeared leaving only a...
