| The Mysterious Rings of Supernova 1987A (February 26, 2012) |
In 1987, the largest supernova in recent history was seen in the Large Magellanic Cloud. In the photograph, the object in the center is the remnants of a violent stellar explosion. The rings surrounding it are unknown but are speculated to have been caused by beamed jets emanating from an otherwise hidden neutron star left over from the supernova, or the interaction of the wind from the progenitor star with gas released before the explosion. Whatever they are, it make for a pretty nifty picture.
