Scientists propose destroying asteroids with sun-powered laser array

This past Friday was not a good day for asteroid-human relations with asteroid 2012 DA14 passing a mere 27,700 km (17,200 miles) from the Earth just a few hours after a meteor exploded over the Russian city of Chelyabinsk, damaging hundreds of buildi ngs and injuring thousands. Scientists have been quick to point out that both of these events – a meteor exploding over a populated area and a large asteroid passing through Earth's geosynchronous orbit – are quite rare, but when the worst case scenario is the complete annihilation of all life on Earth, it's probably best to be prepared.

Energy company to test floating solar islands

Hi Guys,
Can you imagine a power plant which floats in water and generate electricity for our daily life and imagine we are visiting that plant as tourist. Its a reality now.
Swiss energy company Viteos has announced that it is to build three floating solar arrays on Lake Neuchâtel. Viteos will work with tech company and "energy enabler" Nolaris to build the 25-m (82-ft) diameter islands, each with 100 photovoltaic panels.

Pioneering space tourist announces plans for first manned mission to Mars

Hi Guys,
 Their is a new program to mars are you all interested. It is true friends. Dennis Tito, the man who in 2001 became the first space tourist by shelling out a reported US$20 million to hitch a ride on the Russian Soyuz TM-32 spacecraft to the International Space Station, has now announced plans for a manned mission to Mars – and back. Tito won’t be going himself, but has established Inspiration Mars, a new nonprofit foundation that will oversee the mission in the hope of spurring “growth, national prosperity, knowledge and global leadership” through space exploration.

Russian meteor blast heard around the world

Email

When the Chelyabinsk meteor exploded high over Russia on February 15, it was a blast heard around the world. This isn't just a figure of speech. Though too low-frequency for human hearing, sound waves from the 500-kiloton detonation of the 17-meter (56-ft) rock were picked up in Antarctica – some 15,000 km (9,320 miles) away – by 17 Comprehensive Test Ban Treaty Organisation (CTBTO) infrasound stations dedicated to detecting nuclear explosions above or below ground.
The Chelyabinsk meteor was the largest space object to explode on Earth in over a century. It was captured on dramatic videos, knocked down walls, blew in windows and injured about a thousand people as it released as much energy as 30 Hiroshima atomic bombs. It also set off infrasonic waves – sub-audible sounds between 0.001 Hz and 20 Hz. These can travel around the world and are used by the CTBTO’s network of 45 infrasound stations to help enforce treaties against nuclear testing.

NASA confirms the origin of cosmic rays

Hi Friends,
The study of data collected by NASA's Fermi Gamma-ray Space Telescope has revealed that cosmic rays, some of the fastest traveling particles in the universe, are produced by supernovae. A separate study by the European Southern Observatory (ESO) has made similar findings, largely corroborating the Fermi results.
Cosmic rays are subatomic particles, made up of around ninety percent protons, that move through space at close to the speed of light. Magnetic fields deflect and distort the path of the particles, making it near impossible to determine their point of origin. However, the presence of cosmic rays
