Ultra-Bright X-Ray Source Awakens Near a Galaxy Not So Far Away

A new ultra-bright source of X-rays has awakened in between our galactic neighbors the Magellanic Clouds, after a 26-year slumber. This is the second-closest such object known to date, with a ...

Large Simulation Finds New Origin of Supermassive Black Holes

Computer simulations conducted by astrophysicists have revealed a new theory for the origin of supermassive black holes. In this theory, the precursors of supermassive black holes grow by swallowing ...

Under Pressure, Black Holes Feast

A new study shows that some supermassive black holes actually thrive under pressure. It has been known for some time that when distant galaxies -- and the supermassive black holes within their cores ...

ALMA Spots Twinkling Heart of the Milky Way

Astronomers have found quasi-periodic flickers in millimeter-waves from the center of the Milky Way, Sagittarius (Sgr) A*. The team interpreted these blinks to be due to the rotation of radio spots ...

Like Thunder Without Lightning

Mergers between black holes and neutron stars in dense star clusters are quite unlike those that form in isolated regions where stars are few. Their associated features could be crucial to the study ...

ESO Instrument Finds Closest Black Hole to Earth

Astronomers have discovered a black hole lying just 1,000 light-years from Earth. The black hole is closer to our solar system than any other found to date and forms part of a triple system that can ...
