This is one of the most bizarre photos ever taken by the Hubble telescope. It shows a mysterious "ghostly green blob of gas" looming over a spiral galaxy like an evil ghost. The 300,000-light-year-long gas stream is called Hanny's Voorwerp.
Hanny's Voorwerp—which probably means The Galactic Empire of the Nefarious Ones or Hanny's Object in Dutch—is as large as our entire home galaxy, the Milky Way. We only can see part of it in this image because it's illuminated by a searchlight beam from a quasar, located inside the spiral galaxy core—I know, this is getting quite unbelievable—called IC 2947 and located 650 million light-years from Earth. There's an apparent hole in the middle of it, but it's all an optical illusion: NASA scientists think that this is the 20,000 light-year wide shadow from an object between the quasar and the cloud stream, which makes it a shadow projector of galactic proportions. Are we really supposed to believe that?
Astronomers also say that the green cloud—captured using the Advanced Camera for Surveys (ACS) and the Wide Field Camera 3 (WFC3)—glows in green because of the oxygen in it.
Hookay. If you want to believe all that, it's fine by me, but I know that his is no gas stream. This is an alien world fleet illuminated by the green glow of millions of artificial stars with kryptonite cores. Yes, an empire of millions of fully robotized and armed planets populated by evil silicon-based lifeforms. And they are getting ready to invade that spiral galaxy.
Or they were, 650 million light-years ago. Now they are probably headed to Earth. You fools. [NASA]
