An international team of researchers studying dust samples retrieved by the Hayabusa-2 space probe, has found that some of its dust grains are older than the solar system. In their paper published in The Astrophysical Journal ...
(PhysOrg.com) -- A new theory on the source of terrestrial water has been validated by an international team led by Professor Nora de Leeuw (University College London) using computational research.

Planets are thought to form in the disks of dust and gas found around young stars. But astronomers have struggled to assemble a complete theory of their origin that explains how the initial dust develops into planetary systems. ...

(Phys.org) —Surprisingly low temperatures detected in the remnant of the supernova 1987A may explain the mystery of why space is so abundant with dust grains and molecules. The results will be presented by Dr Mikako Matsuura ...

We have a pretty good idea of how planets form around stars. We know that dust is formed from the remnants of supernovae, that protoplanetary disks of dust form around young stars, and that dust grains can clump together ...

A violent outburst by the young star V883 Orionis has given astronomers their first view of a water "snowline" in a protoplanetary disk - the transition point around the star where the temperature and pressure are low enough ...
