Hey Space Placers!
This is one of the most AMAZING pics I have ever seen:

| NASA |
It shows multiple images of a quasar 6 billion light years away that we can see due to the gravitational lensing of a foreground galaxy. A quasar is a galaxy that has an active supermassive black hole at its center. The black hole has infalling matter - planets, comets, gas, etc - that heats up to millions of degrees as it gets consumed. It produces a great deal of light and energy that we can detect and study.
The gravitational lensing helps us to see this quasar and make measurements of the black hole.
See this video to help understand what you are seeing and

Really amazing - what a universe we live in.
