Moon dust's astronomical price

NEW YORK - A bag used by US astronaut Neil Armstrong to bring the first samples of moon dust back to Earth was sold to an anonymous bidder for $1.8 million at an auction in New York on Thursday, marking the 48th anniversary of the first moon landing.

The bag, which for years sat unidentified in a box at the Johnson Space Center in Houston, was bought by a person who bid by telephone and did not wish to be named publicly, auctioneer Sotheby's said.

Auctioneers had expected the bag to fetch between $2 million and $4 million.
