The Eridanus Void. This area shows almost no signs of cosmic matter, meaning no stars, planets, solar systems or clouds of cosmic dust. Researchers couldn't even find dark matter, which is invisible but measurable by its gravitational pull. There were also no signs of black holes that might have gobbled up the matter once present in the region.
That electrical current was discovered near galaxy 3C303. It's not doing anything that cool ... it's just firing a massive jet of electrified matter 150,000 light-years into outer space. RTh 6 Most Mind-Blowing Things Ever Discovered in Space | Cracked.com
Hourglass Nebula Image courtesy IAC The hourglass-shaped nebula Sharpless 2-106 glows in a picture released by NASA on November 7 and taken by the Gran Telescopio CANARIAS in Spain's Canary Islands. Located about 2,000 light-years away, this star-forming region is illuminated by a very young star—about a hundred thousand years old—whose mass is equivalent to that of 15 suns.
See the "?" At top sits the emission nebula known as Cederblad 214, which is part of a larger star-forming complex called NGC 7822. The dot at bottom is a smaller nebula called Sharpless 170. The entire piece of punctuation spans about 40 light-years in the constellation Cepheus.
