What occur to the very first stars in the universe?


Most distant and bright supernova, known to scientists today, probably happens in the explosions when the universe was much younger - just after the Big Bang.

What both these unusually bright and slowly fading. These properties are consistent with what is known as a supernova with the pair instability, a rare explosion mechanism, which is expected to occur with massive stars, is substantially free of metals. 

Three star charts on exoplanets


In these three celestial star charts grouped all available information about exoplanets currently available. Each of them should be extended to enlarge:

1. This letter highlights the sky where the stars have been detected potentially habitable exoplanet. Each is represented by corresponding brightness.

The presence of massive extrasolar planets around star Fomalhaut


Nearest star Fomalhaut has a massive exoplanet, reported NASA scientists after the second study using space telescope "Hubble".

Back in 2008, astronomers announced that they had discovered a planet called Fomalhaut B and shrouded in dust orbiting star Fomalhaut at a distance of 25 light years from Earth.

The orbit of the ISS has been raised by about 1 kilometer



The rectification of the orbit of the International Space Station to avoid a impact with debris U.S. satellite saints held on November 1.

The experts at NASA and the Russian Mission Control Center said they used to contrive the engine docked cargo ship.

Earlier in the Mission Control Center said that the threat of a collision with debris ISS no American satellite. 

Ghost Nebula


This ghostly image was obtained in August 2009 with the vision of wide-field Mosaic Camera on the Mayall 4-meter telescope at Kitt Peak National Observatory. This cloud of cosmic dust, called vdB 141, is a reflection nebula located in the constellation Cepheus, approximately 1,200 light-years away. 

Chasing clouds on Venus


Often spotted clouds blue sky of Earth, but Venus is never clear. This planet is permanently surrounded by a solid covering of carbon dioxide and sulfur dioxide, about 20 kilometers thick.

This image, taken by the European spacecraft Venus Express on December 8, 2011 when it was at about 30,000 miles from Earth, shows the top of the clouds of Venus in ultraviolet wavelengths.

NASA Release: Suomi NPP Captures Night View of U.S. Before Hurricane Sandy's Landfall


Axis Hurricane Sandy made a historic landfall on the New Jersey coast during the night of October 29, the Visible Infrared Imaging Radiometer Suite (VIIRS) on NASA / NOAA’s Suomi National Polar-orbiting Partnership (Suomi NPP) satellite captured this nighttime view of the storm. This image provided by University of Wisconsin-Madison, is a composite or verschillende satellite passes over North America jobs 18 hours before Sandy's landfall.
