Earlier this month, scientists from NASA and the ESA took a massive photograph of the Andromeda galaxy. The picture contains over a billion pixels and takes up over 40GB of hard drive space. Watching the video provided in the source is absolutely mind boggling; it gets very up close and personal, yet each pixel of the image contains, on average, 667 stars. And we have to remember, the Andromeda galaxy is but one of many. There are billions of galaxies in our universe, each with a trillion stars. The vastness of space is truly mind-boggling.
It seems inevitable that we will some day explore this vastness, but what will we find out there? New elements? Systems and objects that break our current understanding of physics? Life? The possibilities are endless, and they are all out there waiting for us.
