New Pulsar Reveals Feeding Habits of Milky Way’s Black Hole

  A team of astronomers, including Heino Falcke (Radboud University Nijmegen/ ASTRON) and Adam Deller (ASTRON), has discovered radio pulses from a neutron star practically next door to the supermassive black hole which resides at the center of the Milky Way. Radio ‘pulsars’ are rapidly spinning neutron stars, ubiquitous in the rest of the Milky [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]

Has Galactic Black Hole Swallowed its Counterpart?

  These days the core of the Milky Way galaxy is a pretty tame place…cosmically speaking. The galactic supermassive black hole at the center is a sleeping giant. Existing stars are peacefully circling. Although conditions are favorable, there doesn’t even seem to be much new star formation going on. Artist’s conception of satellite galaxy being pulled into [continue reading]

Giant, Magnetized Outflows from our Galactic Center

  Two years ago, CfA astronomers reported the discovery of giant, twin lobes of gamma-ray emission protruding about 50,000 light-years above and below the plane of our Milky Way galaxy, and centered on the supermassive black hole at our galaxy’s core. The scientists argued then that the bubbles were produced either by an eruption from [continue reading]

A Mysterious Galactic Cloud in the Center of our Milky Way

  A puzzling cloud near our galaxy’s center may hold clues to how stars are born   It’s the mystery of the curiously dense cloud. And astronomers at the California Institute of Technology are on the case. This image, taken with NASA’s Spitzer infrared space telescope, shows the mysterious galactic cloud, seen as the black [continue reading]

Our Galaxy is Bigger and has More Dark Matter than Thought

  A research team, led by Associate Professor Mareki Honma from the National Astronomical Observatory of Japan (NAOJ), has succeeded in precisely determining the astronomical yardstick for the Milky Way galaxy based upon the precise distance measurements with VERA from NAOJ and other advanced radio telescopes. The new findings are that the distance from the [continue reading]
