Some of us are keen amateur cosmologists
I've been fascinated with the cosmos since a young lad. I don't claim to be an expert by any measure but I've read and studied enough to get a grasp of the basics. But everyday I learn a bit more and still get wowed by the details.
The universe is a massive and amazing place and we haven't even scratched the surface of discovery yet.
Just to give you an idea of the immensity, there are more stars in the observable universe than there are grains of sand on all the beaches combined, here on Earth. There is a good chance that the majority of those stars have planets orbiting them (hundreds have been detected so far) so imagine how many planets there could be!
