I wasn't sure about this one until I looked at the full-res version.
The star colour variations are really quite engaging. Picking out the occasional red star is like spotting "Wally" in the crowd.
Indeed... so many stars reminded me of one of Sagan's quotes:
“The nitrogen in our DNA, the calcium in our teeth, the iron in our blood, the carbon in our apple pies were made in the interiors of collapsing stars. We are made of starstuff.”
― Carl Sagan, Cosmos
Nice one
