Meteorites,Comets and Asteroids

New data provided by the Dawn spacecraft suggests that some of the olivine on Vesta was delivered by asteroid impacts rather than being the product of internal geologic activity.

A software application based on an algorithm created by a NASA challenge has the potential to increase the number of new asteroid discoveries by amateur astronomers.

In an unlikely scenario, the craters that formed the Clearwater Lakes occurred almost 200 million years apart.

NASA's Dawn spacecraft has become the first mission to achieve orbit around a dwarf planet.

Dawn will be the first mission to successfully visit a dwarf planet when it enters orbit around Ceres on Friday, March 6.

The latest images from Dawn, taken nearly 29,000 miles from Ceres, reveal that a bright spot that stands out in previous images lies close to yet another bright area.

Astronomers tinkering with ice and organics in the lab may have discovered why comets are encased in a hard, outer crust.

ESA’s Rosetta probe is preparing to make a close encounter with its comet on 14 February, passing just 6 km from the surface.

Scientists working with NASA's Deep Space Network antenna at Goldstone, California, have released the first radar images of asteroid 2004 BL86.

ESA’s Rosetta mission is providing unique insight into the life cycle of a comet’s dusty surface, watching 67P/C-G as it sheds the dusty coat it has accumulated over the past four years.
