The International Year of Light continues with a beautiful gallery celebrating all aspects of light: multispectral astronomical, technological innovations, bioluminescence, eclipses, and even noctilucent clouds. I'll say this for it: this is the most visually interesting and diverse "Year of..." celebration!
Start the year off with something beautiful: this is Hercules A, a galaxy 1.9 billion light years away. This beauty hides a bite: its central black hole is a devouring monster 1,000 times the mass of our own Sagittarius A* with screaming jets nearly a million light years out.
Specifically, that bright dot in the center of this image is Hercules A, a galaxy located over two billion light-years from Earth. But what really dominates the scene are the two gargantuan jets of plasma shooting out of Hercules A.
