Did You know? Moons & Andromeda Galaxy

All of Uranus’ moons (NASA image above taken by Voyager) are named after characters from Shakespeare and Alexander Pope plays. For example, the Juliet and Portia are the names of two of the moons.

Every year the Moon moves away from the Earth by 3.8 centimetres. In approximately 500 million years from now it will not be possible to have a total solar eclipse.

Even though the Andromeda Galaxy (M31/NGC 224) is one of the nearest major galaxies to the Milky Way, it still takes light 2.5 million years from the galaxy to reach us. When you look at the Andromeda galaxy you are seeing the galaxy as it was 2.5 million years ago.
