The wonder of the Universe

It never ceases to amaze me that when you look up at the sky at night, it looks something like this:



when in actual fact it looks something more like this (but we can't see it):




Note, these are not actual images, merely artistic mock-ups I have doodled - you won't see the sky looking like either of these images (probably).

Once you've decided to look into the Universe there are many amazing thoughts to be had. You could start off with the mind boggling thoughts: there are zillions of galaxies out there, and within each galaxy there are zillions of stars, and new stars are still being formed all the time. We could also ponder upon the strange fact that the expansion of the Universe appears to be accelerating which contravenes the theory that you can't simply conjure energy from nothing. We might also realise that there is no such thing as outside the Universe because it just isn't there. Then there is the more common place idea that we are all made from the material from exploded stars - we are star dust. You might also like to just sit there and imagine infinite space in your mind - how vast can your mind get?

Anyway, you get the gist. If you want to get an idea of what the sky actually looks like at night, then the "Sky Survey" app gives a brilliant view of it.
