Fast radio bursts (FRBs) are notoriously difficult to study. They are flashes of radio light that can outshine a galaxy but often last for only a fraction of a second. For years, all we could do was observe them by random chance and wonder about their origins.

Astronomers have detected thousands of these bursts, but how they are born has been a hotly debated topic. Some theories suggest they originate from powerful shockwaves, while oth

Astronomers finally discovered the origin of fast radio bursts (FRBs)–mysterious and powerful bursts from outer space first seen in 2007.

Fast radio bursts are brief and brilliant explosions of radio waves emitted by extremely compact objects such as neutron stars and possibly black holes. These fleeting fireworks last for just a thousandth of a second and can carry an enormous amount of energy—enough to briefly outshine entire galaxies.

Deep beneath Yellowstone National Park is an enormous volcanic crater hundreds of thousands of years old. Researchers have found a new way to track changes in the crater by studying electromagnetic fields instead of seismic activity. Watch this video to learn what they discovered about the likelihood of another volcanic eruption there.

Innew research, we have for the first time tracked a fast radio burst back to its source: a common kind of lightweight star called a red dwarf.
