(Phys.org)—A team of scientists from six European countries reported today they have finalized a thirty years long investigation of a hypergiant star that crossed the Yellow Evolutionary Void. In that period the star's surface temperature quickly rose from five to eight thousand degrees. With this discovery a crucial 'missing link' in the evolution of hypergiant stars has been found.  http://phys.org/news271324284.html Space & Earth Mon, 05 Nov 2012 07:53:25 EST news271324284 (PhysOrg.com) -- The center of our Milky Way galaxy is about 27,000 light-years away in the direction of the constellation of Sagittarius. At the very center of the galaxy lies a black hole whose mass is about four million solar masses. Around it is a donut-shaped structure about eight light-years across that rings the inner volume of neutral gas and an estimated thousands of individual stars. Around that, stretching out to 700 light-years, is a dense molecular zone of activity, unique to the galaxy, with massive star forming clusters of luminous stars, giant molecular clouds, and many more, poorly understood regions as well. http://phys.org/news232617066.html Space & Earth Mon, 15 Aug 2011 08:51:24 EST news232617066 (PhysOrg.com) -- Using the Canadian MOST microsatellite, a team of researchers from the Universite de Montreal and the Centre de Recherche en Astrophysique du Quebec has made a stunning observation. As they'll report at this week's CASCA 2011 meeting in Ontario, Canada, the team has observed significant changes in the depth of the atmospheric eclipses in the 30-day binary WR+O system CV Serpentis, suggesting a never before seen change of mass-loss rate of the WR component by 70%. http://phys.org/news226049984.html Space & Earth Tue, 31 May 2011 09:30:02 EST news226049984 (PhysOrg.com) -- Betelgeuse -- the second brightest star in the constellation of Orion (the Hunter) -- is a red supergiant, one of the biggest stars known, and almost 1000 times larger than our Sun. It is also one of the most luminous stars known, emitting more light than 100 000 Suns. Such extreme properties foretell the demise of a short-lived stellar king. With an age of only a few million years, Betelgeuse is already nearing the end of its life and is soon doomed to explode as a supernova. When it does, the supernova should be seen easily from Earth, even in broad daylight. http://phys.org/news168073732.html Space & Earth Wed, 29 Jul 2009 08:10:17 EST news168073732
