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.
