It is a rare treat in astronomy when we can actually watch something occur in “real time” as opposed to trying to piece together objects at different stages in their evolution to form a coherent physical picture. This is one reason astronomers were so excited about the unusual transient Swift 1644+57 (Sw 1644+57) , which went off in March of 2011. This object was discussed in several astrobites at the time (see here and here) but as a brief review: Sw 1644+57 was first detected with the Swift Gamma-Ray telescope on March 28th 2011, and ...
