NASA warns of a major solar storm for 2013 suggest

Launching the Solar Dynamics Observatory NASA last February, researchers at the Rutherford Appleton Laboratory, Oxfordshire (England) had warned about the effects of solar winds during the Olympic Games in 2012. NASA experts back to warn of potential danger to Earth the explosion of a single large space storm generated over 150 million miles away, on the surface of the Sun, published by English daily ABC.

"An extremely intense solar activity, in the coming years are expected, increasing levels would cause an unprecedented disaster. Our energy and communication systems would be seriously damaged by the scope of solar plasma and our comfortable Western lifestyle system, which relies more than ever on technology, would collapse like a house of cards, "the newspaper published the portal.

launch new satellites to study the Sun

Picard The satellite dedicated to studying changes in the Earth caused by the sun and the sun's influence on climatic variations was launched into space Tuesday at 14:42 hours from the Russian space base Yasny, reported in National Center of Space Studies of France (CNES).

The Picard was sent into space on a Russian-Ukrainian Dnepr rocket, along with satellites MANGO TANGO and the Franco-Swedish scientific mission PRISMA, designed to study the formation flying satellites, including .

The Picard will measure the speed of rotation of the Sun, the intensity of its rays, the presence of spots on its surface, its shape and diameter to analyze the relationship between these parameters and provide the star storm.

This will serve to assess the influence that the star developments in global temperatures and their contribution to climate change phenomenon, said the CNES. The satellite will serve to "reconstruct" the climatic history of the Sun and thus shed light on past observations about its diameter, were made in the seventeenth century.

was when there was a decrease in average temperature, the phenomenon known as the "Maunder Minimum" (1645-1715) and experts seeking to find confirmation that this event caused in the Sun cooling on Earth.

From that time only have data for measuring the solar diameter made by the French astronomer Jean Picard and now seeks to demonstrate that there was a relationship between them and the solar activity

existence of alien life on a moon of Saturn

Two new studies published in journals suggest the possibility that extraterrestrial life exists on Titan , a moon of Saturn.

The first magazine published in the online edition of Icarus, explains how hydrogen (gas abundant in the atmosphere of the star), disappears when it reaches the surface, so experts believe that some kind of living creature it would absorb, the agency reported today Prensa Latina.

For its part, the NASA Astrobiologist, Chris McKay, said in the Journal of Geophysical Research, that "something is consuming the hydrogen of Titan."

the same way that earthlings absorb oxygen, a way of life consume hydrogen on Titan, said the specialist.

"If confirmed, it will be doubly exciting as it would be a new way of life, independent of water based on Earth," said the scientist.

This planetary scientist at Ames Research Center (NASA) had responded to an interview in 2006: "I think one of the key goals for astrobiology should be the search for life on other planets and in particular the search for a second genesis. "

McKay is working "in the return to the moon with both the Lunar Precursor and Robotic Program, as the Constellation. As co-investigator on the Phoenix Lander and Mars Science Laboratory, is heavily involved in future Mars exploration, "according to the website Planets.

Also, Darrell Strobel, Johns Hopkins University in Baltimore, Maryland, who studies the upper atmosphere of Saturn and Titan emphasized that molecular hydrogen is "chemically very inert in atmosphere very light and very buoyant. " Should "float" into the upper atmosphere and escape, he said.

The studies are based on information obtained from the Cassini spacecraft a cooperative project of NASA, the European Space Agency and the Italian Space Agency, says the report PL.
