 NASA recently tested a new rocket-powered turbine for methane, which could become the key technology for future exploration of the outer solar system.
The main turbine, built and tested by the team of NASA contractors, Alliant Techsystems and XCOR Aerospace, is still under development and, therefore, is not ready yet to be carried into space. But if you can show that this technology is viable, the turbines like this one powered by natural gas could eventually be key to deep space exploration.

The largest planetary ring found so far in the solar system is circling Saturn, about 13 million miles from Earth, as revealed in the infrared images from Spitzer Space Telescope from NASA. This is a huge ring of dust particles, but so dim that it is not evident at first glance.
A team of astronomers from the Universities of Virginia and Maryland in the USA has encountered a huge ring around Saturn thanks to images provided by the infrared Spitzer Space Telescope for NASA. “It’s a super ring and if visible (from Earth) appears to be twice the size of the moon,” says Anne Verbiscer, University of Virginia. The researcher has reported the finding at the congress of the Division for Planetary Sciences of the American Astronomical Association, which this week celebrated in Puerto Rico.

 It was thought that the coldest place in the solar system could be Pluto, since it is the one farthest from the sun, however, LRO lunar reconnaissance spacecraft, launched last June by NASA, has provided a surprising fact: the coldest place in the Solar System on the Moon, just inside the dark craters near its south pole.
By measuring the temperature of different parts of the satellite, its great variability was found like: if during the day much of its surface can reach 104 º C at night the temperature plummets. As the interior of these craters never gets sunlight, stay in eternal darkness and never climb of -240 º C.

 A possible scenario for the formation of the solar system: a cloud of interstellar gas and dust contracted on itself under the action of its own gravity, can be helped in this by the shockwave of a supernova near the explosion giant star (see eg the article by Claude Bertout in the latest issue of “For Science” from July to September 2009).

 The Hubble Space Telescope is back in business, close to discover new worlds, scan deeper into space, and even map the invisible backbone of the universe. The first shots have restored Hubble’s new vision of the telescope 19 years old. The colorful multi-wavelength of large galaxies, a star cluster very crowded, the mysterious “pillar by creating” and a nebulous “butterfly” complete the list of exciting new views.
The Butterfly Nebula, NGC 6302
With his new camera for imaging, Hubble can see galaxies, star clusters and other objects across a wide band of the electromagnetic spectrum from ultraviolet to light NIR. A new spectrograph cutting across billions of light years to map the filamentary structure of the universe and to trace the distribution of elements that are essential to life.
