Planet Without a Sun Discovered 100 Light Years Away
It's gone rogue
In images, it doesn't look like much: just a blue dot against the black of space. What's exciting about this little planet is that it has somehow manage to escape its star.
Even getting an image of the object, dubbed CFBDSIR2149, is a pretty good trick: CFBDSIR2149 is only visible in the infrared, and then, only just (it appears blue in the image because methane in its atmosphere absorbs much of its longer infrared wavelengths, the ESO says).
