The signal, marked FRB 20191221A, is currently the longest lasting FRB, with the clearest periodic pattern detected to date.

Strong energy outbursts that are repeated like a heartbeat are detected billions of light-years from Earth

A mysterious object billions of light-years from Earth emits strong bursts of energy in a pattern resembling a heartbeat. A team of astronomers, led by Massachusetts The Institute of Technology (MIT), picked up what is formally known as fast radio bursts (FRB), which are intense radio waves that usually last a few milliseconds. However, the …

Hubble attaches the mass of a potentially free-floating black hole 5,000 light-years away

Earlier this year, astronomers used microlenses and the Hubble Space Telescope to discover, for the first time, a rogue black hole about 5,000 light-years from Earth. Now, with more accurate measurements, they have been able to determine an approximate mass of this difficult-to-detect object. However, the surprisingly low mass means that there is a chance …
