Three planets in a row

Currently seen the planets Mercury, Venus and Saturn in the morning sky before sunrise the third December is the three planets in a row.

Currently performing the three planets Mercury, Venus and Saturn a cosmic dance in the morning sky before sunrise. Thus stood Venus and Saturn very close together on 27th November, but clouds blocked unfortunately, the view of the planet parade.

If it is clear weather on Monday, the 3rd December, it will be possible to see Mercury, Venus and Saturn in a row with Mercury at the bottom, Venus and Saturn in the middle at the top.

Titan glows in the dark

Picture of the largest of Saturn's Titan, made ​​by NASA's Cassini spacecraft in the dark, showed a mysterious glow of Titan's atmosphere.

If you were standing on the surface of Titan, you would not notice this glow, as his power is only a few millionths of a watt. The scientists were able to fix this weak light with a camera apparatus Cassini, allowing you to take pictures with a long exposure.

Cassini sees giant energy flow on Saturn

NASA's Cassini spacecraft recorded the effects of an ancient giant storm on Saturn. New data pointed to record conflict in the upper atmosphere of the planet, which existed for a long time after the in evidence signs of the storm had disappeared, and that the storm was actually much stronger than previously thought.

In the analysis of data obtained from the composite infrared spectrometer apparatus Cassini, discovered that a powerful electrical discharges that occurred during the storm, Saturn's stratosphere warmed to 83 Kelvin above its normal temperature. 

A type of natural gas in Titan's poles in Saturn

Scientists had already spotted lakes of methane, a type of natural gas in Titan's poles, but so far none had been found in its equatorial regions, which are mostly arid and vast expanses of dunes.

"It was totally unexpected, because the lakes are not stable in tropical latitudes," said Caitlin Griffith of the University of Arizona, director of the team responsible for the finding.

Evidence points to existence moon of Saturn ring

The second largest moon of Saturn, Rhea, could have a small ring around him, reported Thursday a team of international researchers. This was the first time you find rings in a satellite instead of a planet. The findings of the Cassini spacecraft, published in the journal Science, will help scientists better understand how planets form, said Geraint Jones, who worked on the study while at the Max Planck Institute in Germany.

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.

The Saturn

This is the second biggest in our solar system and the only planet whose average mass does not exceed that of water so if there is a sea that surround Saturn could soar.

At Saturn from a modern telescope in 1610, Galileo draw it as a globe bounded by two smaller ones as a head with large ears (the first one who came up with the Mickey Mouse logo). Galileo thought it was moons but when two years later reviewed the planet had disappeared. Later in 1655 the Dutch astronomer Christian Huygens discovered Saturn having had a satellite orbiting Titan, announced that the planet should be surrounded by an equatorial ring.

MARS AND SATURN

The planet Saturn, with details could hardly see our eyes. You can see the Cassini Division separating the rings as well as details of its turbulent surface. Date: April 6, 2012. (Credit: Fernando Silva.)

The red planet is revealed in detail for the CCD camera Fernando Silva. The polluted skies over the city of Santiago de Chile are not an obstacle for the astrophotography captures the details of the Martian surface.

Using a telescope Celestron Nexstar 127 SLT, a Maksutov-Cassegrain with focal radius of 12, ideal for capturing planets and planetary camera of the same brand Reimage, Silva took videos of these objects with little exposure to then add several frames in register.
