Stellar Winds Scatter Star-Forming Material

  A University of Alberta astrophysicist’s 3-D computer animation is helping an international research team get an unprecedented look at star-forming gases escaping from the nearby starburst galaxy NGC 253 (The Sculptor Galaxy).    UAlberta astrophysicist Erik Rosolowsky created this 3-D rendering of carbon monoxide in the starburst galaxy NGC 253 (The Sculptor Galaxy).    Since 2011, [continue reading]

Supernova Remnant is Creating New Molecules

  Astronomers using ALMA, the Atacama Large Millimeter/submillimeter Array, have detected, for the first time, the formation of new molecules in the remains of a star that went supernova. By detecting and mapping the distribution of these molecules, the researchers also have caught a glimpse of the final internal structure of the star, which became [continue reading]

Snow in an Infant Planetary System

  The sight of a snowfall can thrill children, but the first-ever snow line seen around a distant star gives astronomers an even greater thrill because of what it reveals about the formation of planets and our Solar System’s history. Artist concept of snow line in TW Hydrae showing water covered ice grains in the [continue reading]

Witnessing the Birth of a Monster Star

  New observations using the Atacama Large Millimeter/submillimeter array (ALMA) have given astronomers the best view yet of a monster star in the process of forming within a dark cloud. A stellar womb with over 500 times the mass of the Sun has been found — the largest ever seen in the Milky Way — [continue reading]

Large Population of 'Invisible' Galaxies Discovered

  A research team led by Bunyo Hatsukade, a postdoc researcher, and Kouji Ohta, a professor, both from the Graduate School of Science, Kyoto University, revealed that approximately 80% of the unidentifiable millimeter wave signals from the Universe is actually emitted from galaxies, based on the observations with ALMA (Atacama Large Millimeter/submillimeter Array). ALMA’s high [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]
