Composite image of the core region of Messier 87 taken at radio wavelengths showing glowing gas surrounding a supermassive black hole.
Simulated view of a Schwarzschild black hole in front of the Large Magellanic Cloud. Note the gravitational lensing effect, which produces two enlarged but highly distorted views of the Cloud. Across the top, the Milky Way disk appears distorted into an arc. From Wikipedia
