Trillions of comets collide around Fomalhaut


Dust ring around the star Fomalhaut is created in the collision of comets thousands every day.

Located only at a distance of 25 light years from Earth, Fomalhaut is a fairly young star, twice as massive as our sun, and discovered in 1980 in a large amount of dust.

Now, astronomers using a telescope Herschel discovered a dense strip of dusty materials, about half of which is water ice at the edges of the system.
