Astronomers and citizen scientists have found two would-be stars lacking heavy elements. They’re most likely ancient survivors of our galaxy’s earliest days.
This week, astronomers announce a newborn magnetar and a fast radio burst that's bursting to a beat.
One of the most luminous supernovae ever discovered provides evidence that such extremely bright explosions require exotic sources.
The shadow cast by a protoplanetary disk takes the shape of a bat — and over time, flaps like one, too. The eery shadow could help astronomers understand the planet-forming material inside the disk.
Recent observations have pinpointed the location of a fifth fast radio burst, shedding light on the environs that create these powerful sources.
According to Bradley Schaefer (Louisiana State University), the 11th-magnitude variable star, V Sagittae, will outshine Sirius and maybe even Venus — despite its distance of some 7,500 light-years.
