Astronomers in the US have discovered a dust enshrouded star located 300 light years from the earth which looks like a sun. Unlike hundreds of other stars covered with dust, where the dust is far from the star -- equivalent to beyond the orbit of Pluto -- this dust is orbiting close to the star, says science portal www.eurekalert.org, quoting from Nature magazine. "What is so amazing is that the amount of dust around this star is approximately one million times greater than the dust around the sun," said Eric Becklin, a professor of physics and astronomy, a member of NASA's Astrobiology Institute, and co-author of the Nature paper.
