Stellar Monsters Do Not Collide...

  No hope for a spectacular stellar catastrophe   One might expect that collisions between the remains of monstrous stars, with masses reaching 200-300 times that of our Sun, would be among the most spectacular phenomena in the Universe. Perhaps they are, but we will unfortunately probably never have the chance to find out. Astrophysicists [continue reading]

The Birth of a Black Hole Not as Boring as Thought

  A new kind of cosmic flash may reveal something never seen before: the birth of a black hole.   When a massive star exhausts its fuel, it collapses under its own gravity and produces a black hole, an object so dense that not even light can escape its gravitational grip. According to a new [continue reading]

How a Middleweight Black Hole is Created

  A new model co-developed by BMCC Science Professors Saavik Ford and Barry McKernan shows how an elusive type of black hole can be formed in the gas surrounding their supermassive counterparts. This simulated image shows the interaction between a massive gas giant planet (comparable in mass to Jupiter) and a surrounding protoplanetary disk of [continue reading]

NASA's Chandra Sees Remarkable Outburst From Old Black Hole

  An extraordinary outburst produced by a black hole in a nearby galaxy has provided direct evidence for a population of old, volatile stellar black holes. The discovery, made by astronomers using NASA’s Chandra X-ray Observatory, provides new insight into the nature of a mysterious class of black holes that can produce as much energy [continue reading]
