Approximately 200 years ago, according to an international team of researchers, Sagittarius A* (Sgr A*)1, the supermassive black hole at the center of the Milky Way, emerged out of a protracted period of dormancy. The team, led by CNRS researcher Frédéric Marin at the Astronomical Strasbourg Observatory (CNRS/University of Strasbourg),…

Physicists knew black holes eventually disappear particle by particle. Now they think everything else does, too Credit: kyoshino/Getty Images Stars, planets, people and petunias: everything emits a special kind of radiation and will, if it sticks around long enough, evaporate into nothing. That’s the claim in a new study of…

Space The stars that orbit close to the Milky Way's supermassive black hole are already tough to explain – but there also seems to be some stars missing By Leah Crane There seem to be some stars missing near the centre of the Milky Way Shutterstock/structuresxx There is a strange…

The supermassive black hole at the center of our Milky Way galaxy woke up and unleashed a fierce outburst of X-rays around the turn of the 19th century, according to new observations of the 'echoes' of the event. Astronomers have noticed that immense clouds of star-forming molecular gas that inhabit…

Home News Science & Astronomy (Image credit: ESA/Hubble & NASA and N. Grogin (STScI), Acknowledgement: Judy Schmidt) Supermassive black holes at the centers of galaxies in cosmic deserts of the universe, where neighbors are rare and stellar nourishment is scarce, still manage to munch on material more often than their…

A black hole is so compact that nothing can escape its gravitational pull, not even light. (Image credit: Mark Garlick/Science Photo Library via Getty Images) To Earthlings gazing into space, our solar system appears to be surrounded by billions of stars in the Milky Way. But if we look even…

Due to Hawking radiation, black holes will eventually evaporate, but the event horizon is not as crucial as had been believed. Gravity and the curvature of spacetime cause this radiation too. This means that all large objects in the universe, like the remnants of stars, will eventually evaporate. Using a…

Astronomers have confirmed the presence of a second supermassive black hole in the turbulent heart of a distant galaxy.  The scientists also found that both of these cosmic monsters are feeding on gas and dust and that one has a peculiar oblong orbit that sends it plunging through a massive…
