On another April 12th, in 1961, Soviet cosmonaut Yuri Alexseyevich Gagarin became the first human to see planet Earth from space. Commenting on his view from orbit he reported, "The sky is very dark; the Earth is bluish. Everything is seen very clearly". To celebrate, consider this recent image from the orbiting International Space Station.
These are called the Pillars of Creation. Apparently they're already gone, since a supernova can be seen moving towards them. However, since they're so far away from us, we seem them in the past, and the super nova waves have already reached them. We'll see this in the next 1000 years or so, IIRC. Too bad we won't be here to see it :D
