Six seconds comet collision


The 192 light years distant star 49 Cetin is surrounded by a huge ring of comets, which occurs about every six seconds in a collision. With these circumstances, two American astronomers solve an unsolved problem for 17 years: the star is surrounded by a cloud of unusual carbon monoxide. The comet collisions release the gas, the researchers said in the journal "Astrophysical Journal."
