By imaging this cool disk of gas rotate around the supermassive black hole, astronomers can watch how the accretion process unfolds
The Atacama Large Millimeter/submillimeter Array (ALMA) has discovered that two young stars forming from the same swirling protoplanetary disc could in fact be twins
W Hydrae had the same starting mass as our nearest star, but it’s billions of years more evolved
Astronomers have used ALMA to capture a strikingly beautiful view of a delicate bubble of expelled material around the exotic red star U Antliae
The stellar formation area has a peculiar section of compounds
“Now we can do real astrophysical analysis on the burst source and the galaxy that harbours it,” says James Cordes of Cornell University
