Astronomy Picture of the Day publishes one astronomy picture a day. There are plenty of fabulous pictures in the archive, but this one is rally stunning. This picture contains around two million galaxies which is an unbelievable amount of those giants. Even though this picture does not contain all the galaxies in the universe (not even close to), it tells us a little bit of the huge size of the universe. Just imagine how far our nearest galaxy, Andromeda, is from the Earth. Andromeda is currently around 2.3 million light-years away from Earth, and it is just one of the millions of galaxies in the universe. Think about the size a little bit more. It takes 2.3 million years for light to travel from Earth to Andromeda, even though the speed of light is around 300 000 kilometers per hour.

So the universe is just huge. I keep on watching this image which is full of galaxies. Wow, our universe really is huge, so huge.
