When Is a Nova Not a ‘Nova’? When a White Dwarf and a Brown Dwarf Collide

Using ALMA, an international team of astronomers found evidence that a white dwarf and a brown dwarf collided in a short-lived blaze of glory that was witnessed on Earth in 1670 as Nova sub Capite Cygni (a New Star below the Head of the Swan), which...

Fierce Winds Quench Wildfire-Like Starbirth in Far-Flung Galaxy

Astronomers using ALMA, with the aid of a gravitational lens, have detected the most-distant galactic “wind” of molecules ever observed, seen when the universe was only one billion years old. By tracing the outflow of hydroxyl (OH) molecules –...

Pair of Colliding Stars Spill Radioactive Molecules into Space

Astronomers have made the first definitive detection of a radioactive molecule in interstellar space: a form, or isotopologue of aluminum monofluoride (26AlF). The new data – made with ALMA and the NOEMA radio telescopes – reveal that this...

Enduring ‘Radio Rebound’ Powered by Jets From Gamma-Ray Burst:

Astronomers using ALMA studied a cataclysmic stellar explosion known as a gamma-ray burst, or GRB, and found its enduring “afterglow.” The rebound, or reverse shock, triggered by the GRB’s powerful jets slamming into surrounding debris, lasted...
