The evolution of the meteorite flux to the Earth can be studied by determining the terrestrial ages of meteorite collected in hot deserts.

An international study led by researchers from the Institute of Space Sciences, from the Spanish National Research Council (CSIC) and the Institut d'Estudis Espacials de Catalunya has discovered that carbonaceous chondrites, a class of meteorites, incorporated hydrated minerals along with organic material from the protoplanetary disk before the formation of planets.

A study of the Northwest Africa 869 (NWA869) meteorite has provided new information about the physical characteristics of asteroids. NW869 refers to a collection of samples from an L chondrite strewn field discovered in Morocco in 2000.

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.

A specific 4641Da amino acid polymer entity is present in two CV3 meteorites Acfer 086 and Allende, together with its breakdown polymer fragments of mass < 2000Da.

Melting Pots for Life on Earth

Geochemists from Trinity College Dublin's School of Natural Sciences may have found a solution to a long-debated problem as to where - and how - life first formed on Earth.

A new study shown that meteorite impacts on ancient oceans may have created nucleobases and amino acids.

Sugars of extraterrestrial origin have been observed in the interstellar medium (ISM), in at least one comet spectrum, and in several carbonaceous chondritic meteorites that have been recovered from the surface of the Earth.

The insoluble organic matter (IOM) of an unequilibrated enstatite chondrite Sahara (SAH) 97096 has been investigated using a battery of analytical techniques.

Tales from a Martian Rock

A new analysis of a Martian rock that meteorite hunters plucked from an Antarctic ice field 30 years ago this month reveals a record of the planet's climate billions of years ago, back when water likely washed across its surface and any life that ever formed there might have emerged.
