New Method to Weigh Protoplanetary Disks

Astronomers have found a way to directly measure the amount of gas in protoplanetary disks without making assumptions about the relative amounts of different types of gas, making this method more accurate and robust than previous methods. Planets form in protoplanetary disks of gas and dust around young stars. Scientists study protoplanetary disks by looking…

Hydrogen Masers Reveal New Secrets of a Massive Star to ALMA Scientists

Scientists used the unique hydrogen radio recombination lines on MWC 349A to reveal hidden collimated jets. While using the Atacama Large Millimeter/submillimeter Array (ALMA) to study the masers around oddball star MWC 349A scientists discovered something unexpected: a previously unseen jet of material launching from the star’s gas disk at impossibly high speeds. What’s more,…

ALMA Scientists Find Pair of Black Holes Dining Together in Nearby Galaxy Merger

While studying a nearby pair of merging galaxies using the Atacama Large Millimeter/submillimeter Array (ALMA) scientists discovered two supermassive black holes growing simultaneously near the center of the newly coalescing galaxy. These super-hungry giants are the closest together that scientists have ever observed in multiple wavelengths. What’s more, the new research reveals that binary black holes…

ALMA and JWST Reveal Galactic Shock is Shaping Stephan’s Quintet in Mysterious Ways

ALMA and JWST Reveal Galactic Shock is Shaping Stephan’s Quintet in Mysterious Ways Shockwaves resulting from the violent collision between an intruder galaxy and Stephan’s Quintet are helping astronomers to understand how turbulence influences gas in the intergalactic medium. New observations with the Atacama Large Millimeter/submillimeter Array (ALMA) and the James Webb Space Telescope (JWST)…

Hotspots found around young binary stars

This Picture shows the very early stages of a binary star system with some intriguing features. It’s a radio image taken with the Atacama Large Millimeter/submillimeter Array (ALMA). The two young stars, or protostars –– marked with star symbols –– are surrounded by a dusty disc. The colour represents the temperature distribution of the protostars…

Four Telescopes for the Price of One

The ALMA observatory is pleased to announce that it has entered into Joint Proposal agreements with the Space Telescope Science Institute (STScI) for the James Web Space Telescope (JWST), the European Southern Observatory (ESO) for the Very Large Telescope (VLT), and the National Radio Astronomy Observatory (NRAO) for the Karl G. Jansky Very Large Array…

ALMA Successfully Restarted Observations

Forty-eight days after suspending observations due to a cyberattack, the Atacama Large Millimeter/submillimeter Array (ALMA) is observing the sky again. The computing staff has worked diligently to rebuild the affected observatory’s computer system servers and services. This is a crucial milestone in the recovery process. On 29 October, ALMA suffered a cyberattack. The computing staff…

Astronomers Observed the Innermost Structure of a Quasar Jet

At the heart of nearly every galaxy lurks a supermassive black hole. But not all supermassive black holes are alike: there are many types. Quasars, quasi-stellar objects, are one of the brightest and most active types of supermassive black holes. An international group of scientists has published new observations of the first quasar ever identified —…

ALMA Update on the Recovery from Cyberattack

On October 29, 2022, the Atacama Large Millimeter/submillimeter Array (ALMA) suffered a cyberattack on its computer systems, forcing the suspension of astronomical observations and the public website. This event is under investigation by local authorities. The Computing team quickly isolated the Antennas and Correlator systems and the Science Archive data systems. However, communication and other…
