Orbiting Rainbows: Using 'Glitter Clouds' to Search For and Image Exoplanets

The search for exoplanets may one day get a lot more glittery. It sounds a bit like science fiction, but a new NASA proposal called Orbiting Rainbows would use glitter-like materials to help image some of those far-away worlds, which could enable high-resolution imaging at a fraction of the cost.

Planet Directly Observed Orbiting Distant Star

This false-color near-infrared image has been processed to remove most of the scattered light from the star Kappa Andromedae (masked out at center).The “super-Jupiter” companion, Kappa Andromedae b (upper left), lies at a projected distance of about 55 times the average distance between Earth and the sun and about 1.8 times farther than Neptune, […]
