A growing body of research suggests that cosmic dust, originating from asteroid collisions and comet disintegration, may have played a crucial role in sparking the formation of life on Earth. This new ...

Cosmic dust does far more than float through space. It's the raw material from which stars, planets and possibly even life ...

Shells of cosmic dust appear like tree rings around the star Wolf-Rayet 140 in this JWST image. Wolf-Rayet stars are at an advanced stage of their lifecycles, releasing heavy elements into space ...

Most cosmic dust probably comes the Zodiacal cloud, an interplanetary dust cloud that orbits our Sun. Earth passes through this cloud, and the cosmic dust is swept up by our planet's atmosphere.

"The formation of cosmic dust is of critical importance in astronomy," team member and Texas A&M University astronomer, Lifan Wang, said in a statement.

To find out whether cosmic dust could possibly be the source that jump- started prebiotic chemistry (reactions), Walton developed a model together with colleagues from the University of Cambridge.

Astronomers have constructed the first detailed 3D map of the properties of cosmic dust in our home galaxy. For their map, the astronomers used 130 million spectra from ESA's Gaia mission, results ...

Astronomers spy cosmic dust, with a twist, from the very early universe. This baby powder from outer space is unexpectedly rich in carbon. By Jon Kelvey. Published Jul 19, 2023 11:30 AM EDT.

Cosmic dust may have helped to kick-start life on Earth, new research suggests. The findings challenge a widely held assumption that this was not a plausible explanation.
