When exoplanet scientists first spotted patterns in disks of dust and gas around young stars, they thought newly formed planets might be the cause. But a recent NASA study cautions that there may be another explanation—one ...

(PhysOrg.com) -- A new study from scientists in the US has reported that organic compounds could be formed in proto-planetary disks, and could have seeded the development of life in our own and other planetary systems.
(PhysOrg.com) -- The traditional picture of comets as cold, icy, unchanging bodies throughout their history is being reappraised in the light of analyses of dust grains from Comet Wild2. A team led by the University of Leicester ...

The space between stars is not empty—it contains a vast reservoir of diffuse material with about 5-10% of the total mass of our Milky Way galaxy. Most of the material is gas, but about 1% of this mass (quite a lot in astronomical ...
