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]

Remnant of Swallowed Galaxy Detected?

    Peering deep into the vast stellar halo that envelops our Milky Way galaxy, astronomers using NASA’s Hubble Space Telescope have uncovered tantalizing evidence for the possible existence of a shell of stars that are a relic of cannibalism by our Milky Way. This illustration shows the disk of our Milky Way galaxy surrounded [continue reading]

Gaia will Reveal the Secrets of Ultracool Dwarfs

  Among the hundred billion stars which can be observed in the Milky Way, there is a group of stars, the so-named ultracool dwarfs, defined as stars with a temperature below 2500 K, which includes ultracool dwarfs and brown dwarfs. It is a really interesting group: they are the most ancient objects in our Galaxy [continue reading]
