International study suggests a massive black hole exists in the Sword of Orion
(Phys.org)—An international team of astrophysicists, including UQ's Dr Holger Baumgardt, has shed light on the long-standing mystery of the binding force behind a cluster of unruly and rapidly swirling stars located in the famous Sword of Orion.
A 200Msol black hole only 1300 light years away.... COOL! And if a supernova happened 1.5-2 My ago, there might be ionization evidence in petrified tree rings or other fossils!
only if a star fell into it, and we were at perfect right angles to it's rotation where an xray jet would impact us directly.... and if that were the case, the initial supernova would've done quite a number on the atmosphere, if it survived at all.... presuming this is a supernova remnant and not the remnant of a dwarf galaxy
