For the first time, astronomers using ALMA have witnessed 3D motions of gas in a planet-forming disk. At three locations in the disk around a young star called HD 163296, gas is flowing like a waterfall into gaps that are most likely caused by planets in formation.
Atacama Large Millimeter/submillimeter Array

First Canadian ALMA Large Program to Investigate the Impact of Galaxy Environment on Star Formation
The first ever Canadian-led Atacama Large Millimeter/submillimeter Array (ALMA) Large Program has been approved for cycle 7. Dr. Brown and his colleagues will use the Atacama Compact Array (ACA) to study the influence of galaxy environment on star formation in the Virgo Cluster.
Dosvedanya and Farewell, RadioAstron
On May 30, 2019, the Russian RadioAstron satellite — the farthest element of an Earth-to-space radio-telescope system — ended its service.
From the Earth, a pulsar looks like a star that has a pulse, a rapid beat picked up only by radio telescopes.
As soon as it came online, ALMA began providing valuable information about extrasolar planetary systems at all stages of their evolution.
