A NASA satellite captured this view of volcanic fissures in Hawaii.

NASA's Terra satellite took a look at the hot fissures on May 6. The satellite's ASTER camera sees in thermal infrared, which is why vegetation appears red in this image. Older lava flows are black and gray and the bright yellow spots superimposed on the satellite view show fresh cracks and flowing lava.
