Galaxy's gigantic star discovered

Canadian scientists have discovered the hugest star so far in the Galaxy. Researchers from Montreal University in alliance with an international team of astrophysicists; have found that the super-large star has a weight 116 times that of the sun.The researchers has discovered the super-massive star in the company of yet another massive star whose mass is also 89 times that of the sun.These two massive stars form a binary system, with the lighter star waltzing around its heavier companion. They have a rotation period of 3.77 days.

Located in the massive star cluster NGC 3603 of the Milky Way, the super-massive two-star binary system has been named A1, a university statement said. NGC 3603 (entry number 3603 of the New General Catalogue) is a giant cloud of gas and plasma which is several hundred light years across and lies in the Constellation Carina in the Milky Way. It is about 20,000 light years from the sun.

The statement said the masses of these massive stars were calculated by a combination of observations made with the SINFONI (spectrometer for infra-red faint field imaging) instrument on the Very Large Telescope at the European Organization for Astronomical Research centre in Chile, and infrared images coming from the Hubble Space Telescope. The two stars are so massive and bright that the light they transmit shows characteristics that only Wolf-Rayet stars possess.

Flying saucer (or) unidentified flying object

Flying saucer is a type of unidentified flying object (UFO) with a disc- or saucer shaped body. It is described as silver or metallic covered with running lights or surrounded with a glowing light, moving rapidly either alone or in tight formations with other similar craft.

The first highly publicized sighting was seen by Kenneth Arnold on June 24, 1947. He never specifically used the term "flying saucer" and he was quoted the shape of the objects as a "saucer", "disc", or "pie-plate", and several years later added he had also said "the objects moved like saucers skipping across the water."

Flying objects sighting was followed by thousands of similar sightings across the world. Such sightings were once very common, to such an extent that "flying saucer" was turn a synonym for UFO.

On 56th indepence day, August 15 2003, India's Prime Minister Atal Bihari Vajpayee announced. "Our country is now ready to fly high in the field of science. I am pleased to announce that India will send her own spacecraft to the moon by 2008. It is being named Chandrayaan-1". In Sanskrit (language of Ancient India) "Chandrayaan" means "Moon Craft".
Moon has always fascinated Indians from ancient days and now 21st century india is ready to land on moon! Chandrayaan-1 is the first mission towords the dream. In Chandrayaan-1, the lunar craft would be launched using Polar Satellite Launch Vehicle (PSLV) weighing 1304 kg at launch and 590 kg at lunar orbit. Lunar craft would orbit around moon 100 km from moon surface.
