An international team of scientists has observed six stars similar to the sun with extraordinary dust belts. "We were surprised that such cold debris disks exist at all," Alexander Krivov, the lead author of the new study, said. By way of comparison, the Kuiper belt is about 70 C degree warmer, and some of the disks even reach room temperature. The six debris disks are mysterious for yet another reason. According to this, the cold debris disks only consist of bigger but at the same time not-too-big rocks. The calculations of the scientists suggest that the radius of the particles lies between several millimeters and several kilometers maximum. via Science - Google News http://news.google.com/news/url?sa=t&fd=R&usg=AFQjCNFUCwGZLb8UzdyhGZSm3Km44YHc4g&url=http://www.hindustantimes.com/world-news/Americas/Herschel-Observatory-discovers-6-Sun-like-stars/Article1-1090032.aspx | |||
