The barycenter is the point in space around which two objects orbit. For the Moon and Earth, that point is about 1000 miles (1700 km) beneath your feet, or about three-quarters of the way from the Earth’s center to its surface. That means the Earth actually wobbles around a point deep in its interior, pulled around by the Moon.

On April 24, 1990, the Hubble Space Telescope was launched into orbit.

“No matter what Hubble reveals — planets, dense star fields, colorful interstellar nebulae, deadly black holes, graceful colliding galaxies, the large-scale structure of the Universe — each image establishes your own private vista on the cosmos.” - Neil deGrasse Tyson
