Dust is everywhere — not just in your attic or under your bed, but also in outer space. To astronomers, dust can be a nuisance by blocking the light of distant stars, or it can be a tool to study the ...

A research team led by University of Minnesota School of Physics and Astronomy Professor Yong-Zhong Qian uses new models and evidence from meteorites to show that a low-mass supernova triggered the ...

WASHINGTON, April 12, 2022 – Molecular clouds are collections of gas and dust in space. When left alone, the clouds remain in their state of peaceful equilibrium. But when triggered by some external ...

Stars are thought to form within enormous filaments of molecular gas. Regions where one or more of these filaments meet, known as hubs, are where massive stars form. These massive stars, located ...

Supernova remnants serve as natural laboratories in which the interplay between high-temperature chemistry, rapid expansion and shock-driven processing gives rise to the condensation of dust grains.

When triggered by some external agent, shockwaves can propagate through molecular clouds of gas and dust to create pockets of dense material. At a certain limit, that dense gas and dust collapses and ...
