Enormous image of the center of the Milky Way


An international team of astronomers has created a directory enclose more than 84 million stars in the Milky Way. The basis for this proposal is a huge picture of the size of nine gigapixel, which amounted to an infrared VISTA telescope data Chilean observatory.

Image of stars the size is nine meters long and seven meters wide.

Roberto Saito, the lead researcher of the Pontifical Catholic University of Chile considers that this work will help to better understand the formation and evolution of spiral galaxies.

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. 

The giant exoplanet zombie rises from the dead


Huge extrasolar planet, which many astronomers thought the "dead and buried", came back to life, researchers say.

A new study of the results of observations made ​​space telescope "Hubble", found lying around nearby star Fomalhaut us really exists giant exoplanet, which scientists dubbed exoplanets, "zombies." These findings oppose the results of other recent studies claiming that the so-called "planet" - known as Fomalhaut b - is actually a huge cloud of dust.
