What’s the mechanism behind millisecond-duration bursts of radio energy coming from outer space? A team searched for visible-light counterparts to constrain the origin of fast radio bursts — and found one.
Astronomers are starting to close in on the origins of fast radio bursts — powerful, fleeting flashes of radio waves seen at extragalactic distances.
A new study uses precise measurements of chemical elements to explore the formation history of one of the oldest globular clusters in the Milky Way.
The supermassive black hole at the center of the Milky Way released an unusual number of strong flares in 2019. Now, astronomers are trying to figure out why.
