An international collaboration of astronomers, including researchers from the University of Toronto, have detected the brightest Fast Radio Burst (FRB) to date—and have been able to pinpoint its ...

An international team of astronomers reports the discovery of a new "spider" millisecond pulsar, which received designation PSR J1544−2555. The finding was presented in a research paper published ...

With help from amateur astronomers, scientists tracked how an asteroid travelled from space, broke up in Earth's atmosphere and sent fiery fragments shooting to the ground, gathering new information ...

Astronomers have uncovered a massive new trans-Neptunian object, 2017 OF201, lurking at the edge of our solar system. With an orbit stretching 25,000 years and a size that may qualify it as a dwarf ...

Right now a comet is hurtling through our solar system at more than 137,000 miles per hour. But it is not just this interstellar object’s speed that has earthly astronomers glued to their telescopes.

"If this is a massive star, it is a collapse unlike anything we have ever witnessed before." Astronomers have spotted a cosmic explosion of high-energy gamma-rays unlike any ever seen before. The ...

Astronomers are trying to understand what caused a series of gamma ray bursts, or GRBs — the most powerful explosions in the universe. These energetic bursts are typically unleashed by the incendiary ...

Astronomers might be close to confirming the presence of an Earth-like atmosphere on an exoplanet for the first time, if more detailed analyses verify preliminary observations from the James Webb ...

Astronomers have spotted a quasi-moon near Earth — and the small space rock has likely been hanging out near our planet unseen by telescopes for about 60 years, according to new research. The newly ...
