- Messier 87 (Wikipedia)
Messier 87 (also known as Virgo A or NGC 4486, generally abbreviated to M87) is a supergiant elliptical galaxy in the constellation Virgo that contains several trillion stars. One of the largest and most massive galaxies in the local universe, it has a large population of globular clusters—about 15,000 compared with the 150–200 orbiting the Milky Way—and a jet of energetic plasma that originates at the core and extends at least 1,500 parsecs (4,900 light-years), traveling at a relativistic speed. It is one of the brightest radio sources in the sky and a popular target for both amateur and professional astronomers.

Missile Command is a 1980 shoot ’em up arcade video game developed and published by Atari, Inc. and later licensed to Sega for Japanese and European releases. It was designed by Dave Theurer, who also designed Atari’s vector graphics game Tempest from the same year. The game was released during the Cold War, and the player uses a trackball to defend six cities from intercontinental ballistic missiles by launching anti-ballistic missiles from three bases.
