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.
Scientists with the Laser Interferometer Gravitational-wave Observatory (LIGO) and Virgo collaborations have announced the detection of a second pair of neutron stars that went bump in the night.
Astronomers have detected a long-sought signal from gamma-ray bursts — the highest-energy photons ever seen from these events.
Remember KIC 8462852, better known as Boyajian’s star (or you may have seen it referred to as the “alien megastructure” star)? We still don’t have a definitive explanation for this source’s odd behavior — in part because we thought that Boyajian’s star was one-of-a-kind.
The amateurs of the AAVSO monitored the star T Ursae Minoris for a century. Now, astronomers think they can explain the star's recent change in behavior.
Astronomers announce another planet around Beta Pictoris, simulations explain Jupiter's large and fuzzy core, and observations reveal an ancient star.
