The second largest moon Rhea against Saturn transit

The second largest moon of Saturn might have its own ring system, which has not been found in any other known satellite, according to a study by the Max Planck Institute for Solar System Research in Lindau Katllenburg-(Germany) published in the journal Science.

The researchers, led by Geraint Jones, analyzed data from the spacecraft Cassini, "which recently flew over Rhea, and report on a surprising lack of electrons around the moon. This phenomenon is interesting because Rhea lies within Saturn's magnetosphere, a vast magnetic bubble that surrounds the planet and kept inside a trapped ions and electrons.

A galaxy settled by traveling planets

The endurance of planets lonely worlds turn around a star, but float alone traveling in space. Far from being an exception, these planets, which may have been expelled from their systems, are very numerous. Researchers from the Kavli Institute for Particle Astrophysics and Cosmology (KIPAC), an independent laboratory of Stanford University in Palo Alto, California, believe that, in fact, there are 100,000 for every star that exists in our galaxy. The Milky Way is full.

‘Danielson and Kalocsa’ the craters on Mars shows how the global climate change

A crater of image on Mars could hold evidence of how temperature evolves on the planet, variable considerably due to changes in the orientation of its axis of rotation. On June 19, 2011, Mars Express said its high-resolution stereo camera to the Arabia Terra region of Mars, photographed the craters Danielson and Kalocsa. The first is called the George E. Danielson, a key player in the development of several satellite cameras shipped in exploring the Red Planet. In this image from Mars Express, Danielson is the crater of the right (north), about 60 km in diameter.

A class 1 hurricane ‘Carlotta’ become in the Pacific

"Carlotta" a Category hurricane becomes in the Pacific and affecting northwest parallel to the Mexican west coast, said the National Meteorological Service (SMN) of Mexico. Meteorologist Bandala Erendira said at 10:00 local time (15:00 GMT) "Carlotta" became a hurricane and its danger rating went from "moderate" to "strong." The hurricane, the second this season in the Pacific, is located 195 kilometers south-southeast of Puerto Angel, Oaxaca state (southern Mexico), and 530 miles south of Acapulco, Guerrero. The sources of SMN, an agency of National Water Commission (Conagua), added that maintaining an alert for the coastal strip running from Tonala Bar, in the state of Chiapas, to Tecpan de Galeana, in Guerrero, southern Mexico.

Civilization is predictable to come into contact with outer space being in 20 years

A famous astronomer said that mankind will have contact with outer space bright being within 20 years (as reported on 4 "Daily Mail" Britain). The current discovery of Earth-like planets outside our solar system and an important job American NASA space by 2009 civilization will make a big step toward contact with outer space beings. In a BBC documentary screened in England tomorrow night, the American astrophysicist Frank Delaroix says: "It makes us more optimistic." Delaroix began in 1961 with a plan to seek extraterrestrial intelligent life. He said: "We are confident that within 20 years we know about the situation in extraterrestrial life.

A dying star points its gun gamma rays Sun

A star located 7,000 light years from Earth will generate a flow of poisonous gamma rays and is aim it seems that to our solar system, according to a team of physicists and astronomers. Within a few hundred thousand years, in short, as the clocks of cosmologists-Rayet star Wolf 104 (WR104), actually more of a binary system of two stars that revolve around a common center of gravity, will explode violently in a supernova

except it will not do since most huge stars, according to Peter Tut hill, a researcher at the School of Physics, University of Sydney (Australia), published this month in the important Astrophysical Journal work of several years leading a team of researchers.

European scientists experienced the plant increase in space

During the European Columbus laboratory has begin the first research, which aim to examine whether plants might produce in outer space. The research, called WAICO ("Waving and coiling of Arabidopsis Roots at Different g-levels' or ripple and roll roots of Arabidopsis at different levels-g), study the effects of weightlessness on the growth of plant roots. Toward this purpose has selected a variety of wild and genetically modified plant Arabidopsis.
