Planet forming disk distortion. Computer illustration of a lump of material in a swirling, planet-forming disk around the star LRLL 31, located about 1,000 light-years away in the IC 348 region of the constellation Perseus. Planets are born out of spinning disks of gas and dust and can carve out lanes or gaps in the disks as they grow bigger and bigger. Astronomers using NASA's Spitzer Space Telescope found evidence that a companion to the star - either another star or a planet - could be pushing planetary material together, as shown here.
