New explanation for Moon’s half-century magnetic mystery

Posted: 13 Jan 2022 08:14 AM PST

A new study reveals how the diminutive Moon could have been an occasional magnetic powerhouse early in its history, a question that has confounded researchers since NASA's Apollo program began in the 1960s.

ALMA catches 'intruder' redhanded in rarely detected stellar flyby event

Posted: 13 Jan 2022 08:14 AM PST

Scientists made a rare detection of a likely stellar flyby event in the Z Canis Majoris (Z CMa) star system. An intruder -- not bound to the system -- object came in close proximity to and interacted with the environment surrounding the binary protostar, causing the formation of chaotic, stretched-out streams of dust and gas in the disk surrounding it.

'Slushy' magma ocean led to formation of the Moon’s crust
