According to new observations from the Spritzer Space
Telescope for NASA, a group of comets is disgraceful collide and kicking up
dust around a dead star. The star is at the center of the much-photographed
Helix nebula (Helix), a bright cloud of gas with an uncanny resemblance to a
giant eye.
"We were surprised to see so much dust around this
star," said Dr. Kate Su of the University of Arizona in Tucson, lead
author of the article written about the results. The work will appear in
the March 1 issue of Astrophysical Journal Letters."The dust must be
coming from comets that survived the death of their sun."
