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]

Incredible Number of Comet Collisions Explain Stellar Mystery

  Every six seconds, for millions of years, comets have been colliding with one another near a star in the constellation Cetus called 49 CETI, which is visible to the naked eye. An artsists concept of a “Kuiper Belt” with comets. Image Credit: NASA/JPL-Caltech Over the past three decades, astronomers have discovered hundreds of dusty [continue reading]
