A Huge Explosion in Space

[bison]

A huge explosion  in a neighboring galaxy has attracted a great deal of scientific interest. It seems to defy our understanding of how supernovas work. It is suspected that multiple objects in orbit of one another are responsible.

Please find a link, below, to an article with further information. Note: the article errs in connecting the Atlas survey, which discovered this object, with the Keck Telescope.

I've found mentioned in various articles, at least 6 ways in which this explosion differs from an ordinary supernova. 

1.)  10 to 100 times brighter than a supernova.

2.) A very rapid rise in brightness; a few days, as opposed to a few weeks in a supernova.

3. A smooth optical spectrum, with no lines, either of absorption or emission.

4.) Radioactive decay of nickel, which reportedly powers supernovas, is insufficient to explain such a bright explosion.

5.) An even distribution of energy at all wavelengths, radio to x-rays, unlike a supernova.

6.) A more rapid expansion into space than expected of a supernova.

All taken together, this certainly seems to be an extraordinary event. It's no wonder that dozens of professional astronomers are keeping an eye on it.
