Cool Star Fact


Pictoris Picture

This Hubble Space Telescope visible-light view of the edge-on disk of dust around the star Beta Pictoris yields telltale evidence for the existence of planets. The "false color" image shows gradations in the brightness of the disk, caused by the fact that the disk shines by reflected starlight, and so the farther the dust is from the central star, the fainter it is. The bright glare of the central star is blocked by a black circle which divides the disk into left (east) and right (west) components.
