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.
