Peering under galactic dust, study reveals radiation at center of Milky Way

Thanks to 20 years of homegrown galactic data, astronomers at the University of Wisconsin–Madison, UW–Whitewater and Embry-Riddle Aeronautical University have finally figured out just how much energy permeates the center of the Milky Way.
The researchers say it could one day help astronomers track down where all that energy comes from. Understanding the source of the radiation could help explain not only the nature of the Milky Way, but the countless others that resemble it.

ALMA Discovers Massive Rotating Disk in Early Universe

In our 13.8 billion-year-old universe, most galaxies like our Milky Way form gradually, reaching their large mass relatively late. But a new discovery made with the Atacama Large Millimeter/submillimeter Array (ALMA) of a massive rotating disk galaxy, seen when the universe was only ten percent of its current age, challenges the traditional models of galaxy formation. This research appears on 20 May 2020 in the journal Nature.

Discovery points to origin of mysterious ultraviolet radiation

Lyman-alpha blobs (LABs) are gigantic clouds of hydrogen gas that produce ultraviolet light known as Lyman-alpha emissions. A study of Lyman-alpha blob 6 (LAB-6) is the first LAB with infalling gas feature. The findings suggest that star-forming galaxies are likely the primary energy source of Lyman-alpha radiation emitted from LAB-6.
