Astronomers Discover Magnetic Loops Around Supermassive Black Hole

For the first time, astronomers using the High Sensitivity Array — a multi-facility network supported by the U.S. National Science Foundation National Radio Astronomy Observatory — have observed evidence of magnetic filaments in the accretion disk surrounding a nearby galaxy’s supermassive black hole.

ALMA Reveals Planets Can Form Under Harsh Radiation

An international team of astronomers used ALMA to capture high-resolution images of eight protoplanetary disks in the Sigma Orionis cluster, which is irradiated by intense ultraviolet light from a massive nearby star. To their surprise, they found evidence of gaps and rings in most of the disks—structures commonly associated with the formation of giant planets, like Jupiter.
