NASA posted a photo today of the Lighthouse nebula. The image shows the aftermath of a supernova, including a runaway pulsar and a spiraling jet that's 37 light-years long, which is the longest known object in the Milky Way. NASA even conveniently marked the radioactive debris field to identify some of its remarkable objects.

Thursday on Big Think, we featured a story about the new x-ray technology that's allowing NASA researchers to look inside a supernova--an exploding star that makes up the stuff of earth.
