Amazing Andromeda Galaxy

The Andromeda is the largest galaxy neighbouring our Milky Way System. The Milky Way which encompasses our solar system made up of stars, space dust, gases and all that other wonderful stuff, is where our harmless little world is. The width of the Milky Way disk is 100,000 light years accross.

When I started out reading about the universe, the word disk, sort of stuck out. Disk includes everything in a galaxies system, right down to the space dust. Some Stars also have disks with floating debris and space dust orbiting around them, which were once planets.

The Andromeda disk is 260,000 lightyears accross, which means that not only would it take 260,000 earth years for a light beam to travel from one end to another, but it is about three times bigger than our own milky way galaxy. Theres very definitely intelligent life out there! Imagine what they could be getting up to. For the full article click on the link below.
