Orion Nebula

Closer Than Thought

The widely photographed and heavily studied Orion Nebula is nearly 300 light-years closer to Earth than previously thought, according to a new study. 


The finding, detailed in the Oct. 10 issue of Astrophysical Journal, also hikes up the age of the nebula's stellar inhabitants. "These stars are nearly twice as old as previously thought," said study team member Geoff Bower, an astronomer at the University of California, Berkeley.


The new measurements were made using the National Science Foundation's Very Long Baseline Array (VLBA). The scientists determined the distance to a star called GMR A, one of a cluster of stars in the Orion Nebula, by measuring the slight shift in the star's apparent position while the Earth was on opposite sides of its annual orbit around the sun.

Joke of the Day

Little Tim was in the garden filling in a hole when his neighbor peered over the fence. Interested in what the youngster was up to, he politely asked, "What are you up to there, Tim?" "My goldfish died," replied Tim tearfully, without looking up, "and I've just buried him." The neighbor was concerned, "That's an awfully big hole for a goldfish, isn't it?" Tim patted down the last heap of earth then replied, "That's because he's inside your cat."

Divers Chart Old Shipwreck in Alaska

A private dive team exploring the waters of south-central Alaska has discovered the oldest American shipwreck ever found in the state, officials said Monday. 

The Torrent sank 139 years ago in
Cook Inlet after tidal currents, among the world's most powerful, rammed it into a reef south of the Kenai Peninsula. Documents from the period show that all 155 people on board survived.
