ALMA finds well-developed protoplanetary discs around young suns

12 December 2018 Astronomy Now

The Atacama Large Millimeter/submillimeter Array has captured stunning views of 20 protoplanetary discs around young, nearby stars, all of them suggesting planets are forming faster than expected

ALMA helps solve an astronomical cold case

10 October 2018 Astronomy Now

Astronomers say an apparent nova that appeared in the constellation Cygnus 348 years ago likely was caused by a collision between a compact white dwarf and a ‘failed star’ known as a brown dwarf.
