Mysterious Repeating Fast Radio Burst Traced to Nearby Galaxy

Astronomers have traced the signal of an enigmatic repeating fast radio burst for only the second time -- and it's in a spiral galaxy similar to our own, not so far away.

Fast radio bursts, or FRBs, are millisecond-long bursts of radio waves in space. Individual radio bursts emit once and don't repeat. Repeating fast radio bursts are known to send out short energetic radio waves multiple times.

ALMA spots supernova dust factory

Aerospace & Defense

Striking new observations with the Atacama Large Millimeter/ submillimeter Array (ALMA) telescope capture, for the first time, the remains of a recent supernova brimming with freshly formed dust. If enough of this dust makes the perilous transition into interstellar space, it could explain how many galaxies acquired their dusty, dusky appearance.

ALMA pinpoints early galaxies at record speed

A team of astronomers has used the new ALMA (Atacama Large Millimeter/submillimeter Array) telescope to pinpoint the locations of over 100 of the most fertile star-forming galaxies in the early Universe. ALMA is so powerful that, in just a few hours, it captured as many observations of these galaxies as have been made by all similar telescopes worldwide over a span of more than a decade.
