Description
Three views of our galaxy. Looking south in the left panels, the moon glows a vibrant orange during a solar eclipse as the Milky Way and the planet Mars compete for attention above the shore of Lake Huron as the village of Sauble Beach glows on an autumn night. Looking north, the Milky Way and Andromeda galaxies soar above the shore Most people are familiar with the "milky" swath of millions of stars that we see looking across our 100,000 light year-wide Milky Way Galaxy, but few have seen the Andromeda galaxy. It is the frisbee-shaped disc in the upper right of frame and the scale and distance to it are nearly incomprehensible.
Think about what we are seeing: It is a whole other galaxy! The Andromeda Galaxy is 2.5 million light-years away and is about 200,000 light-years across. It is believed to contain about 400 billion stars. In terms of the universe, it is a nearby neighbor to our galaxy, yet the light we are looking at began coming to us 2.5 million years ago! Whew!
