NASA’s Chandra Adds to Black Hole Birth Announcement.

On the left, an optical image from the Digitized Sky Survey shows Cygnus X-1, outlined in a red box. Cygnus X-1 is located near large active regions of star formation in the Milky Way, as seen in this image that spans some 700 light years across. An artist's illustration on the right depicts what astronomers think is happening within the Cygnus X-1 system. Cygnus X-1 is a so-called stellar-mass black hole, a class of black holes that comes from the collapse of a massive star. The black hole pulls material from a massive, blue companion star toward it. This material forms a disk (shown in red and orange) that rotates around the black hole before falling into it or being redirected away from the black hole in the form of powerful jets.

Dark matter even darker than once thought.

Released 26 March 2.015, link to publication. Astronomers using observations from the NASA/ESA Hubble Space Telescope and NASA’s Chandra X-ray Observatory have studied how dark matter in clusters of galaxies behaves when the clusters collide. The results, published in the journal Science on 27 March 2015, show that dark matter interacts with itself even less… Sigue leyendo Dark matter even darker than once thought.

International Team of Researchers Uses the Large Millimeter Telescope to Observe a Powerful Molecular Wind in an Active Spiral Galaxy.

An international team of astrophysicists using the Large Millimeter Telescope (LMT) in central Mexico has detected an unexpected and powerful outflow of molecular gas in a distant active galaxy similar to the Milky Way. The galaxy is 800 million light years from Earth. The findings are published in the current edition of Astrophysical Journal Letters, link to article. The research team includes Min S. Yun, a professor of astronomy at the University of Massachusetts Amherst, and colleagues from Mexico’s Instituto Nacional de Astrofísica, Óptica y Electrónica (INAOE), the National Autonomous University of Mexico (UNAM) and institutions in Italy, Belgium, Finland, the Netherlands, Germany and Spain.
