Powerful Gamma-Ray Flares from the Crab Nebula
Scientists Rolf Buehler and Stefan Funk discovered two short duration but powerful gamma-ray flares in the Crab Nebula. These flares only lasted a few days but they were shockingly energetic and occurred extremely rapidly. According to the report, "the pulses were fueled by the most energetic particles ever traced to a discrete astronomical object." These flares are single-handedly challenging current theories about the way cosmic particles are accelerated and will hopefully lead to new discoveries. Read this article for more information.

This is really interesting! I think it's amazing that this nebula has been catalogued for so long, yet nothing close to these events have yet been observed. I know we haven't learned much of anything about nebulas yet but I got a little confused. There's other nebulas visible from Earth, so why is this one so special? Is it the first of its kind to emit such flares or is this just a case unique to the nebula itself?
