(Phys.org)—A group of astronomers has discovered a giant nebula of ionized gas extending over 300,000 light years. This nebula turns out to be associated with the quasar dubbed the "Teacup." The finding was presented November ...

Plasma from lasers can shed light on cosmic rays, solar eruptions

Lasers that generate plasma can provide insight into bursts of subatomic particles that occur in deep space, scientists have found. Such findings could help scientists understand cosmic rays, solar flares and solar eruptions—emissions ...

New model to research activity around quasars, black holes

A University of Wyoming researcher played a key role in a study that suggests a newly developed computer model can more accurately explain the diversity of quasar broad emission line regions, which are the clouds of hot, ...

Minor merger kicks supermassive black hole into high gear

The galaxy Messier 77 (M77) is famous for its super-active nucleus that releases enormous energy across the electromagnetic spectrum, ranging from x-ray to radio wavelengths. Yet, despite its highly active core, the galaxy ...
