Nasa Blueshift

The makings of new planets lie in dusty, debris-filled disks rotating around stars, held in place and shaped by the influence of their host stars. But the dust, ice, and small bodies in these planet-forming disks also feel the effects of a system's motion through space - and interaction with interstellar gas can warp a dusty disk into a weird and unexpected shape. We spoke with Goddard astrophysicist John Debes about his team's research into these oddly-shaped disks. Using the Hubble Space Telescope, scientists are investigating these disks in hopes of finding clues about how other planetary systems are formed - and perhaps even discovering the origins of our own.
