Stellar Rubble May Be Planetary Building Blocks
This artist's concept depicts a pulsar, which is a type of dead star, as well as the surrounding disk of rubble discovered by NASA's Spitzer Space Telescope. The pulsar, called 4U 0142+61, was once a massive star until about 100,000 years ago when it blew up in a supernova explosion and scattered dusty debris into space.
