Most Distant Galaxy is Forming Stars Extremely Fast

  University of Texas at Austin astronomer Steven Finkelstein has led a team that has discovered and measured the distance to the most distant galaxy ever found. The galaxy is seen as it was at a time just 700 million years after the Big Bang. An artist’s rendition of the newly discovered most distant galaxy [continue reading]

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]

11.5 Billion Years Ago Galaxies Had Already Mature Shapes

  Studying the evolution and anatomy of galaxies using the Hubble Space Telescope, an international team of astronomers led by doctoral candidate BoMee Lee and her advisor Mauro Giavalisco at the University of Massachusetts Amherst have established that mature-looking galaxies existed much earlier than previously known, when the Universe was only about 2.5 billion years [continue reading]

The Sculptor Galaxy and the Limits to Galactic Growth

  Astronomers have long assumed that when a galaxy produces too many stars too quickly, it greatly reduces its capacity for producing stars in the future. Now, a group of astronomers that includes Fabian Walter from the Max Planck Institute for Astronomy were able to obtain the first detailed images of this type of self-limiting [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]

Distant Starburst Galaxy Challenges Galaxy Evolution Theory

  ESA’s Herschel space observatory has discovered an extremely distant galaxy making stars more than 2000 times faster than our own Milky Way. Seen at a time when the Universe was less than a billion years old, its mere existence challenges our theories of galaxy evolution. Artist’s impression of starburst galaxy HFLS3. The galaxy appears [continue reading]
