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.

Trio of Infant Planets Discovered around Newborn Star
June 7, 2018 at 2:59 pm | News Release

Two independent teams of astronomers have uncovered convincing evidence that three young planets are in orbit around an infant star known as HD 163296. Using a new planet-finding strategy, the astronomers identified three discrete disturbances in a young star’s gas-filled disk: the strongest evidence yet that newly formed planets are in orbit there.

Zoom into galaxies that are evolving into a galaxy cluster
Astronomers Witness Galaxy Megamerger
April 25, 2018 at 1:00 pm | News Release

ALMA has uncovered 14 distant galaxies that are poised to merge, forming the core of what will eventually become a colossal galaxy cluster.

Image Release: ALMA Reveals Inner Web of Stellar Nursery
March 7, 2018 at 6:00 am | News Feature

New data from ALMA and other telescopes reveal stunning web of filaments in the Orion Nebula.

Powerful Flare from Star Proxima Centauri Detected with ALMA
February 26, 2018 at 8:50 am | News Release

ALMA data reveal that a powerful stellar flare erupted from Proxima Centauri last March. This space weather may make that system rather inhospitable to life after all.

Stellar Embryos in Nearby Dwarf Galaxy Contain Surprisingly Complex Organic Molecules
January 30, 2018 at 2:00 pm | News Release

Astronomers using ALMA have conclusively detected the largest, most complex molecules ever observed outside the Milky Way.
