ALMA Cycle 10 will start in October 2023….

  • New Method to Weigh Protoplanetary Disks

    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…

  • New Method to Weigh Protoplanetary Disks

  • Scientists studying masers— naturally occurring lasers that amplify microwave radio emissions— around the massive star MWC 349A discovered a 500 km/s jet of material launching out of the star’s gas disk from within the winds that are flowing away from the star. The bigger surprise is that the jet may be caused by magnetic forces. This artist’s conception shows a zoomed in view of MWC 349A and its surrounding disk of gas and dust that are being shaped by the winds and high-speed jet. Credit: ALMA (ESO/NAOJ/NRAO), M.
