Space is one area which is always positive (unless you are a dying star!). There are so many great images of star fields now being taken and I guess within our lifetimes there will be some great discoveries. A time of wonders!
Here is a great image from Terry Hancock of www.downunderobservatory.com of the Heart Nebula.
(According to Terry) IC1805 most commonly known as The Heart Nebula lies some 7500 light years away from us and is located in the constellation Cassiopeia. This is an emission nebula showing glowing gas and dark dust lanes. This nebula is formed by the plasma of ionized hydrogen and free electrons.
