ALMA Found One of the Brightest and Massive Protostars

  Thanks to data detected with the ALMA radio telescope, the Atacama Large Millimeter/submillimeter Array, Chilean and foreign astronomers were able to detect a star in formation–a protostar–that appears to be one of the brightest and massive found in our Milky Way galaxy. The giant  molecular cloud known as G331.5-0.1, which is located in the [continue reading]

Signs of Star Formation Near Milky Way's Black Hole

  Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have discovered signs of star formation perilously close to the supermassive black hole at the center of our Milky Way Galaxy. If confirmed, this would be the first time that star formation was observed so close to the galactic center. A combined ALMA and Very Large [continue reading]

How To Build A Really, Really Big Star

  It takes a village, say researchers   Stars ten times as massive as the Sun, or more, should not exist: as they grow, they tend to push away the gas they feed on, starving their own growth. Westerhout 3 (W3) is a giant molecular cloud about 6200 light-years away in the Perseus Arm, one of the [continue reading]
