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.
Meet the white dwarf that defies all expectations.
Astronomers have narrowed down the location of a third "fast radio burst" to a galaxy very like the Milky Way.
What causes the bizarre, extragalactic fast radio bursts we’ve detected over the last decade? An unusually bright supernova may hold the answer.
New measurements from the European Space Agency’s Gaia satellite show that the young stars of the Hyades cluster are beginning to drift apart.
Scientists have caught a powerful flare of submillimeter-wavelength radiation from a young star in the Orion Nebula.
A vision from 70 years ago, the Zwicky Transient Facility has produced a wave of discoveries — but it’s only a hint of what’s to come.
Astronomers can't agree on what kind of strange stellar death created a brilliant source dubbed "the Cow."
Do star clusters form all at once or over several generations? A team of astronomers finds an answer among the spinning stars of an amateur favorite, the Wild Duck Cluster.
