BANG. Astronomers serendipitously found the supernova SN 2008d, located in the galaxy NGC 2770, through X-ray observations (labeled as XRF080109). This observation marks the first finding of signs of a stellar explosion emitted so soon after a star's demise. The two other supernovas labeled here were found in this galaxy last year and in 1999.

The thought of gamma ray bursts scares me.

Are they sure it wasn’t due to the “Hillary Effect” because of the Wyoming results?

...using wide-angle X-ray telescopes could routinely witness the very beginnings of hundreds of supernova explosions each year... Wow, fantastic! Just when you think astronomers will never have an opportunity to observe a supernova from the moment it blows, unless they get luckier than the luckiest lottery player who ever lived, along comes a serendipitous find that says that they're probably going to be able to observe hundreds of them each year from a few moments before they blow, right on through all the fireworks. Too amazing. Bound to lead to a much, much richer understanding of the inner workings of stars!

I thought X-rays and visibile light both traveled at the same speed. Why would the X-rays arrive first?
