New York, March 21 : A rare dinosaur skeleton as much as 150-million years old is expected to fetch 500,000 million dollars at the Natural History Auction in Manhattan.

The Jurassic Dryosaurus carcass has been put under the hammer by I. M. Chait Gallery at 267 Fifth Avenue.

London, March 21: Using images from the Mars Odyssey spacecraft, NASA scientists have discovered what could be mud volcanoes on the planet, in which life might be bubbling in muddy squirts.

According to a report in New Scientist, Dorothy Oehler and Carlton Allen of NASA’s Johnson Space Center in Houston, Texas, identified dozens of mounds at a site in the northern plains of Mars that bear a striking resemblance to mud volcanoes on Earth.

These form a distinctive large hill of sediment with a central crater.

Washington  - The final solar panel at the space station began unfurling, as planned, on Friday, the final event in the years- long expansion of the energy capacity of the orbiter.

The panel, installed Thursday during a spacewalk by astronauts from the Discovery shuttle, started unfolding at 1506 GMT.

"Everything looking good so far," said a NASA official in Houston in the live webcast on NASA TV. She said the process would take some time, and be halted midway to allow the device to "warm in the sun" - necessary to avoid sticking.
