Fragmenting Disk Gives Birth to Binary Star ‘Odd Couple’
Fragmenting Disk Gives Birth to Binary Star ‘Odd Couple’
December 13, 2018 at 10:57 am | News Release

ALMA has detected a star in a binary system that may have formed like a planet.

The Epoch of Planet Formation, Times Twenty
December 12, 2018 at 9:00 am | News Release

ALMA has conducted a survey of protoplanetary disks, the planet-forming dust belts around young stars.

Trans-galactic Streamers Feeding Most Luminous Galaxy in the Universe
November 15, 2018 at 2:00 pm | News Release

New ALMA data reveal distinct streamers of material being pulled from three smaller galaxies into the larger galaxy W2246-0526, the most luminous known galaxy in the universe.

When Is a Nova Not a ‘Nova’? When a White Dwarf and a Brown Dwarf Collide
October 8, 2018 at 12:00 am | News Release

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.

Fierce Winds Quench Wildfire-like Starbirth in Far-flung Galaxy
September 6, 2018 at 1:10 pm | News Release

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 – which herald the presence of star-forming gas in galaxies – the researchers show how some galaxies in the early universe quenched an ongoing wildfire of starbirth.

First Science with ALMA’s Highest-Frequency Capabilities
August 17, 2018 at 11:00 am | News Release

Band 10, ALMA’s highest frequency vision, has given scientists a new view of jets of warm water vapor streaming away from a newly forming star and uncovered an astonishing assortment of molecules.

Pair of Colliding Stars Spill Radioactive Molecules into Space
July 30, 2018 at 11:00 am | News Release

Astronomers have made the first definitive detection of a radioactive molecule in interstellar space: a form, or isotopologue of aluminum monofluoride. The new data reveal that this radioactive isotopologue was created by the collision of two stars, a tremendously rare cosmic event that was witnessed on Earth as a “new star,” or nova, in the year 1670.

Enduring ‘Radio Rebound’ Powered by Jets from Gamma-Ray Burst
July 26, 2018 at 11:00 am | News Release

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 thousands of times longer than expected.
