(CBS News) An observatory in the mountains of southern New Mexico that is dedicated to unlocking the mysteries of the sun has found itself at the center of a mystery that is creating a buzz here on earth. Authorities remain tightlipped Friday, saying only that an undisclosed security concern was behind the decision to abruptly vacate and lock up the remote facility on Sept 6.
The Sunspot Solar Observatory has been closed for more than a week.
The FBI referred all questions to the group that manages the site, the Association of Universities for Research in Astronomy. Officials there say they're working with authorities.
