Optical Vortex Coronagraph Could Look Directly At Extrasolar Planets - SpaceDaily Left: These laboratory limages demonstrate how the optical vortex coronograph works. They were obtained with a green "star" and red "planet" (point light sources). (a) shows how the green light is "spun out," while the red light remains unaffected. Images of the point sources are shown when large (b) and small (c) apertures are used to limit the transmission of light from (a). Reported by: Foo et al. in Optics Letters for 1 December 2005. A new optical device might allow astronomers to view extrasolar planets directly without the annoying glare of the parent star. It would do this by "nulling" out the light of the parent star by exploiting its wave nature, leaving the reflected light from the nearby planet to be observed in space-based detectors About ten years ago the presence of planets around stars other than our sun was first deduced by the very tiny wobble in the star's spectrum of light imposed by the mutual tug between the star and its satellite. Since then more than 100 extrasolar planets have been detected in this way. Also, in a few cases the slight diminution in the star's radiation caused by the transit of the planet across in front of the star has been observed. Many astronomers would, however, like to view the planet directly - a difficult thing to do. Seeing the planet next to its bright star has been compared to trying to discern, from a hundred meters away, the light of a match held up next to the glare of an automobile's headlight. It could fully come into its own on a project like the Terrestrial Planet Finder, or TPF, a proposed orbiting telescope to be developed over the coming decade and designed to image exoplanets. |

Ancient Canals Reveal Underpinnings Of Early Andean Civilization - SpaceDaily Canals discovered in the Peruvian Andes dating back over 5,400 years offer long-sought proof that irrigation was at the heart of the development of one of the earth's first civilizations. The anthropologists discovered the canals in Peru's upper middle Zana Valley, approximately 60 kilometers east of the Pacific coast. Preliminary results indicate one of the canals is over 6,700 years old, while another has been confirmed to be over 5,400 years old. They are the oldest such canals yet discovered in South America. "Peru is one of the few places on the planet where there was independent development of civilization." |

India Successfully Test Fires Supersonic Cruise Missile - SpaceDaily India on Wednesday successfully test-fired an army version of its supersonic BrahMos cruise missile that was jointly developed with Russia, a defence officer said. The missile was tested from Indias Chandipur-on-sea site, 200 kilometres (125 miles) northeast of Bhubaneswar, the capital of the southeastern state of Orissa. "The missile has a range of 290 kilometers (181 miles) and can carry a 300-kilogram (660 pounds) conventional warhead and can be launched from land, ships, submarines and aircraft, the officer said. The eight-metre (26-foot) missile weighs about three metric tonnes. |
