Mensa (constellation): A faint constellation in the Southern Celestial Hemisphere, named after Table Mountain in South Africa, and created by French astronomer Nicolas-Louis de Lacaille in the 18th century.
Stars: Mensa contains no bright stars, but several dim stars with interesting properties, such as exoplanets, circumstellar disks, eclipsing binaries, and variable stars.
Galaxies and quasars: Mensa partly covers the Large Magellanic Cloud, a satellite galaxy of the Milky Way, which contains many star clusters and nebulae. Mensa also hosts a distant quasar with a long gas jet, visible in multiple wavelengths.
