NASA Publishes Unprecedented X-Ray Image Of Supernova Remnant
Once again, the Universe amazes me with a never-before-seen display of colour and shapes that defies belief. You are looking at Puppis A, a supernova remnant that is 7000 light years away and is 10 light years across (!) And yet it looks like microscopic view of a coral here on Earth. Amazingly beautiful.
