Using ALMA’s exceptionally sharp vision, astronomers have uncovered rings, gaps, and cavities in extremely compact disks ...

A remarkably detailed image obtained with the Atacama Large Millimeter/submillimeter Array (ALMA) reveals the uneven surface of Betelgeuse, the famous red supergiant in the constellation Orion. The ...

Ever since ALMA captured the striking image of HL Tau in 2014, revealing intricate rings and gaps in a disk around a newborn star, astronomers have sought to understand how such complex structures ...

At simultaneous press conferences around the world, including at the ALMA observatory offices in Santiago, Chile, astronomers have unveiled the first image of the supermassive black hole at the center ...

Astronomers have used the Atacama Large Millimeter/submillimeter Array (ALMA) to map, for the first time, the mass distribution of the gas and dust clumps from which new stars are born—the so-called ...

A major ALMA survey of young stars has uncovered widespread methanol masers and the first detection in space of fully deuterated methanol An international team of astronomers using the Atacama Large ...

Using the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers have detected the magnetic field of a galaxy so far away that its light has taken more than 11 billion years to reach us. We ...

Unusual shape of Fomalhaut’s debris ring shows evidence of sculpting by ancient planets, rewriting story of planetary system evolution The bright star in the center, Fomalhaut, is surrounded by an ...

The James Webb Space Telescope (JWST) has captured unprecedented details of the Butterfly Nebula (NGC 6302), a planetary nebula located about 3,400 light-years away in the constellation Scorpius. To ...

Using the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers have captured one of the most detailed three-dimensional views yet of a massive binary star system while it is still being ...

For the first time, astronomers have captured images of a star other than the Sun in enough detail to track the motion of bubbling gas on its surface. The images of the star, R Doradus, were obtained ...

ALMA has mapped a roughly one-trillion-mile gas streamer feeding GW Orionis, linking late-stage infall from the surrounding cloud to the triple-star system’s strikingly misaligned planet-forming rings ...
