Surprise! There's an enormous dying star right near by.

The most studied star in the sky--with the obvious exception of the sun--has suddenly started to die a violent death trailing material over 13 lightyears.

It is thought that a hot bow-wave of compressed plasma/gas is the cause of the tail; the bow-wave is a result of the interaction of the stellar wind from Mira A with gas in the interstellar space, through which Mira is moving at an extremely high speed of 130 kilometres/second.

Also pretty picture on wiki.

I LOVE how flukes, blind chance and telescope mis-alignment regularly yield amazing discoveries from deep space. Like they said, the chance for this picture to actually be taken was, pardon the pun, astronomical. Just imagine then, how many fantastic discoveries we would make if only we could "cover" even as much as a hundredth of a percent of the sky with telescopes. That's why I really think it's about frakking time we started substantially increasing investements in astronomy and related sciences.

The predator could see this! Lucky guys.
