Is This Gamma-Ray Burst a Shredded Star in Disguise?

Is GRB 191019A a typical burst of gamma rays from a dying star, an anomalously long burst from colliding objects, or something else entirely?

Is Betelgeuse Fading Again?

Betelgeuse has dipped nearly half a magnitude since late January. Could it be headed for another Great Dimming Event? We also take a look at this spring's "other" eclipse.

Radio Burst Breaks Distance Record, Challenges Theories

A highly energetic fast radio burst, which broke the distance record, provides a crucial test for theories of these events' origins.

An illustration of one of brightest explosions ever seen in space. Called a Luminous Fast Blue Optical Transient (LBOT), it shines intensely in blue light. It appears as a bright white blob left of centre where blue-white and red rays sprout out from it. Toward the right of the image there is a white spiral galaxy. To the upper left is another whitish galaxy shaped like a cigar. The LFBOT doesn’t seem to be associated with either galaxy.
