Versailles, France: 1939 Execution of the German criminal Eugčne Weidmann (born 1908) which was the last one performed in public. Several hundred additional spectators were apparently gathered behind a second cordon, not visible in this photograph. Roger-Viollet / The Image Works. LINK
The Yellow + is a location called Sagittarius A*. These images were observed between 1992 and 2002. They show stars orbiting Sagittarius A*, sometimes at phenomenal speeds (up to 1,000 kilometers per second.)
Zooming in, you can see the incredible velocity of the orbiting stars as they get closer to Sagittarius A*.
The evidence can only point to one natural phenomenon we know about, a black hole. This black hole is what's known as a "supermassive block hole", packing about 4 million times the mass of the sun into an incredibly dense region of space. Astronomers have found ample evidence that a similar monster (often times much larger than Sagittarius A*) reside near the center of almost every galaxy.
