This is amazing news folks!! Space zipping will no more remain a dream. We have news that a revolutionary Spacecraft by the name of Skylon, may one day, in a matter of just 15 minutes, carry the adventure lovers into Earth’s Stratosphere.

Asteroid 2012 DA14 asteroid may zip past Earth: NASA

Record breaking Asteroid flyby is expected on the 15th of February say the NASA astronomers. The astronomer termed small Asteroid 2012 DA14 approximately weighing 130,000 metric tons and measuring about 45 meters in diameter is expected to pass close our planet even nearer than our communication and weather satellites.

By century end, western evergreen forest could turn scrubland-- suggets study

A new research suggests that the western evergreen forests, which cover an area from southern Canada to northern Mexico, took up a lot less carbon from the atmosphere during the drought that lasted from 2000-2004.

Intensifying acid level in the sea is a stunning menace for the coral reefs and sea life

Acidification of the ocean has materialized as one of the prime hazards for the coral reefs spread worldwide. The superfluous carbon dioxide in the atmosphere has slipped into the recesses of the oceans universally and has lead to an alarming increase in the acid level of the deep-sea bodies that has the scientists stunned.

Colossal solar twisters raise the sun’s temperature to exhorbitant degrees

Enormous and gigantic 'solar twisters' that are nearly 1000 miles broad have been found to take the sun's atmosphere to very high temperatures, as high as millions of degrees centigrade. These magnetic tornadoes swirling around are found to heat the immediate layer above the sun to extremely high levels, channeling extreme temperatures from the sun on to the layer above it making it scorching hot. The heat is so high that it can lend enough power to make “clean” reactors on earth. The tornadoes that are seen on the Earth are thousands of times smaller, of lesser intensity than the solar tornadoes.

Venus clouds may yield climate clues

Paris -- European scientists say a mysterious, high-altitude layer of sulphur dioxide in the atmosphere of Venus has been explained, with possible earthly connections.

Sulphuric acid clouds blanket Venus at an altitude of between 30 and 45 miles, formed by sulfur dioxide from volcanoes combining with water to form sulfuric acid droplets.

Intense solar radiation above 45 miles should destroy any sulfur dioxide above that height, so scientists were puzzled when a European Space Agency probe found a layer of sulfur dioxide at about 55 miles, an ESA release said.

FAA issues private spacecraft permit

Washington -- The U.S. Federal Aviation Administration issued the first-ever license for a commercial spacecraft to re-enter Earth's atmosphere from orbit, officials say.

The license will allow the California-based company SpaceX to complete the first operational flight of the Dragon spacecraft during a NASA demonstration mission set for a Dec. 7 launch, Florida Today reported.

After its launch from Cape Canaveral atop a Falcon 9 rocket, the Dragon will orbit the planet twice before re-entering and splashing down in the Pacific Ocean off Southern California.

"The flight of Dragon will be an important step toward commercial cargo delivery to the International Space Station," NASA Administrator Charlie Bolden said in a statement.

Scientists: Asteroid could destroy ozone

Tucson -- An asteroid colliding with Earth could wipe out the ozone layer forcing humans into a vampire-like life of hiding indoors during daylight hours, scientists say.

Scientists at the Planetary Science Institute in Tucson, Ariz., say an asteroid a half-mile wide could create a worldwide hole in the ozone layer with a massive loss of protection against the sun's ultraviolet radiation, reported Tuesday.

Their computer models showed ozone destruction resulting from an asteroid impact in the world's oceans launching seawater vapor hundreds of miles into the atmosphere.

Students help end satellite mission

Boulder, Colo. -- Colorado students took part in an unusual decommissioning of a satellite, bringing the craft into Earth re-entry to burn up in the atmosphere, scientists say.

University of Colorado at Boulder undergraduates, who have been helping to control five NASA satellites from campus, guided the Ice, Cloud and Land Elevation Satellite, or ICESat, out of orbit into Earth's atmosphere Monday, a university release said.

After seven years of gathering valuable data on the polar regions and helping scientists develop a better understanding of ice sheets and sea ice dynamics, the science package on the satellite failed, leading to the decommissioning.

Warmer climate could release lake CO2

Uppsala, Sweden -- Carbon dioxide locked in the world's freshwater lakes could be released into the atmosphere as warmer climate conditions continue, scientists say.

Swedish researchers say organically bound carbon is held in temperature-sensitive sediments, sometimes for thousands of years, but warmer climate could result in much of it being released into the atmosphere as carbon dioxide, a study published in the journal Nature reported.

Researchers at Uppsala University have found a strong connection between the carbon dioxide production in lake sediment and bottom-water temperature, the study says.
