In an experiment to collide lead nuclei together at CERN’s Large Hadron Collider physicists from the ALICE detector team including researchers from the University of Birmingham have discovered that the very early Universe was not only very hot and dense but behaved like a hot liquid.

The origin of the rivers in India comprises three prime watersheds:
The Indian rivers can be classified into the
Himalayan Rivers,
Deccan Rivers ,
Coastal Rivers,
Rivers of the inland Drainage basin .
Talking about the Indian Rivers, the rivers that one thinks of are Ganga and Yamuna . However, India is home to several other rivers like Brahmaputra, Krishna, Cauvery, Narmada and many more. Besides rendering a pleasing beauty to the country, the Indian Rivers also happens to be an important source of transportation, hydro-electricity and most importantly irrigation. The lives of the boatmen, farmers, fishermen and others depend on these water bodies. A large number of crops depend on the water from the rivers. Further the rivers in India are indispensably connected to Indian culture. Wrapped in religious ethos and mythology, these rivers also draw numerous tourists from all corners of the world. Various dams and multipurpose projects on Indian Rivers have been undertaken at various times thus making the rivers in India a source of economy as well. With change in time the function of the Indian rivers have underwent major sea changes. The rivers like Alaknanda etc are being made use of for various purposes like adventure sports, river rafting etc. The Indian rivers bear the evidences of the oldest civilization. Hence these are significant religiously, historically, and culturally. Twisting through the valleys the rivers come down to nurture the lands, in the same way as it did hundreds of years ago.

UC Berkeley astronomers Andrew Howard and Geoffrey Marcy chose 166 G and K stars within 80 light years of Earth and observed them with the powerful Keck telescope for five years in order to determine the number, mass and orbital distance of any of the stars’ planets. The sun is the best known of the G stars, which are yellow, while K-type dwarfs are slightly smaller, orange-red stars.
According to them nearly one in four stars like the sun could have Earth-size planets, according to a University of California, Berkeley, study of nearby solar-mass stars…..

Astronomers using NASA’s Chandra X-ray Observatory have found evidence of the youngest black hole known to exist in our cosmic neighborhood. The 30-year-old black hole provides a unique opportunity to watch this type of object develop from infancy.The 30-year-old object is a remnant of SN 1979C, a supernova in the galaxy M100 approximately 50 million light years from Earth. Data from Chandra, NASA’s Swift satellite, the European Space Agency’s XMM-Newton and the German ROSAT observatory revealed a bright source of X-rays that has remained steady during observation from 1995 to 2007. This suggests the object is a black hole being fed either by material falling into it from the supernova or a binary companion.
