In newer times great achievements have been made and at present we know very much about our universe. the overwhelming fast achievements in techonology in the last century and the possibilities of modern personal computers have made astronomy accesible for everyone.
There is much knowledge now about the universe and space and it's objects (for example Supernovae).
Imagine – it has become a lot easier to get to know the science of astronomy for everyone. You don't need to be a scientist yourself to see into the universe. There are a lot of very good software projects and relatively cheap beginners telescopes that enable everyone to deepen the knowledge about our universe (e.g. Which telescope is best for beginners. Many of tose resources are very affordable and quite a lot software products are even available for free.
But even if you are not interested in the science behind it, there is so much beauty in some of those pictures. The structures and colors seen on those pictures fascinate almost anyone who has the chance to take a look at them. Some of the best pictures can be found here: New Site for NASA Pictures
Discover the the versatility of astronomy, which is both – a science and a hobby. It can give you the joy of watching pictures almost like art or you can use it to train your brain with the math behind it.
