Forecasting a Supernova Explosion

  Type II supernovae are formed when massive stars collapse, initiating giant explosions. It is thought that stars emit a burst of mass as a precursor to the supernova explosion. If this process were better understood, it could be used to predict and study supernova events in their earliest stages. New observations from a team [continue reading]

The Power of Messier 82's Superwinds

  An international team of astronomers, led by Dr. Kazuya Matsubayshi (Kyoto University), has discovered that outflows of gas from starburst galaxy Messier 82 (see below) collide with a “cap” of gas clouds 40,000 light-years away from the galactic disk. Shockwaves (Note 1) from M82’s central starburst region are the most likely source of the [continue reading]

Black Widow Pulsar in Tango Mortale Vaporizes Partner

  Max Planck scientists discover record-breaking millisecond pulsar with new analysis method.   Pulsars are the compact remnants from supernova explosions of massive stars. Some of them spin around their own axis hundreds of times per second, emitting beams of radiation into space. Until now, they could only be found through their pulsed radio emissions.

‘Seeds’ of Supermassive Black Holes Found

  A research team at Keio University, led by Associate Professor Tomoharu Oka, has discovered intermediate-mass black hole (IMBH) candidates at the center of the Milky Way Galaxy. It is about 30,000 light-years from the solar system in the direction of Sagittarius. IMBH candidates are considered to be the “seeds” that form and grow supermassive [continue reading]
