Meteorites,Comets and Asteroids

Comets made up of two lobes, such as Chury, visited by the Rosetta spacecraft, are produced when the debris resulting from a destructive collision between two comets clumps together again.

Earth began to receive water from space even before our planet had fully formed.

Two wayward space rocks, which separately crashed to Earth in 1998 after circulating in our solar system’s asteroid belt for billions of years, share something else in common: the ingredients for life.

For the first time, researchers from the COSIMA team present a quantitative analysis of which chemical elements make up comet 67P/Churyumov-Gerasimenko.

Interplanetary dust colliding with our atmosphere could provide the energy to eject microbes into space.

New data reveal first detected interstellar object to be a rocky, and up to one-quarter mile (400 meters) long and highly-elongated-perhaps 10 times as long as it is wide.

Asteroids key to understanding our Solar System's formation.

Surface features on Ceres -- the largest world between Mars and Jupiter -- and its interior evolution have a closer relationship than one might think.

Hydrogen in comets explains how water moves around Solar System.

The Chicxulub asteroid impact that wiped out the dinosaurs likely released far more climate-altering sulfur gas into the atmosphere than originally thought, according to new research.
