You are looking at Puppis A, a supernova remnant that is 7,000 light years away and is 10 light years across (!) And yet it looks like microscopic view of a coral here on Earth. Amazingly beautiful.
Capture by NASA’s Chandra X-Ray Observatory and the European Space Agency’s XMM-Newton, “the image shows the remains of a supernova that would have been witnessed on Earth about 3,700 years ago. The remnant is called Puppis A, and is around 7,000 light years away and about 10 light years across. This image provides the most complete and detailed X-ray view of Puppis A ever obtained, made by combining a mosaic of different Chandra and XMM-Newton observations. Low-energy X-rays are shown in red, medium-energy X-rays are in green and high energy X-rays are colored blue.”
