This graph of data from NASA Spitzer Space Telescope demonstrates that the dust around a nearby star called HD 69830 upper line has a very similar composition to that of Comet Hale-Bopp.

Super-Comet or Big Asteroid Belt?

This graph of data from NASA Spitzer Space Telescope demonstrates that the dust around a nearby star called HD 69830 upper line has a very similar composition to that of Comet Hale-Bopp.

Evidence for this possible belt was discovered by NASA Spitzer Space Telescope when it spotted warm dust around the star, presumably from asteroids smashing together. This is an artist concept.

Band of Rubble Artist Concept

This artist concept shows what the night sky might look like from a hypothetical alien planet in a star system with an asteroid belt 25 times as massive as the one in our own solar system.
