Crystals-2-PIA03048.jpgCrystals around a Brown Dwarf70 visiteThis artist's concept shows microscopic crystals in the dusty disk surrounding a Brown Dwarf, or "failed star." The crystals, made up of a green mineral found on Earth called olivine, are thought to help seed the formation of planets.
NASA's Spitzer Space Telescope detected the tiny crystals circling around five brown dwarfs, the cooler and smaller cousins of stars. Though crystallized minerals have been seen in space before - in comets and around other stars - the discovery represents the first time the little gem-like particles have been spotted around confirmed brown dwarfs.
Astronomers believe planets form out of disks of dust that circle young brown dwarfs and stars. Over time, the various minerals making up the disks crystallize and begin to clump together. Eventually, the clumps collide and stick, building up mass like snowmen until planets are born.

CygnusX1.jpgCygnus X-1 and Cygnus OB377 visiteDa "NASA - Picture of the Day" del 2 Aprile 2005:"The formation of a Black Hole from the collapsing core of a massive star is thought to be heralded by a spectacular supernova explosion. Such an extremely energetic collapse is also a leading explanation for the mysterious cosmic Gamma-Ray bursts. But Researchers now suggest that the Milky Way's most famous black hole, Cyg X-1, was born when a massive star collapsed without any supernova explosion at all. Their dynamical evidence is summarized in this color image of a region in Cygnus, showing Cyg X-1 and a cluster of massive stars (yellow circles) known as Cygnus OB3. Arrows compare the measured direction and speed of Cyg X-1 and the average direction and speed of the massive stars of Cyg OB3. The similar motions indicate that Cyg X-1's progenitor star was itself a cluster member and that its path was not altered at all when it became a Black Hole. In contrast, if Cyg X-1 were born in a violent supernova it would have likely received a fierce kick, changing its course. If not a supernova, could the formation of the Cyg X-1 black hole have produced a dark gamma-ray burst in the Milky Way? ".

D-RAD.jpgDeinococcus Radiodurans: the "Terra-Farmers"...74 visiteThese bacteria could survive on another planet. In an Earth lab, Deinococcus Radiodurans (D. Rad) survive extreme levels of radiation, extreme temperatures, dehydration, and exposure to genotoxic chemicals. Amazingly, they even have the ability to repair their own DNA, usually within 48 hours.
Known as an extremophile, bacteria such as D. Rad are of interest to NASA partly because they might be adaptable to help human astronauts survive on other worlds. A recent map of D. Rad's DNA might allow biologists to augment their survival skills with the ability to produce medicine, clean water and oxygen.
Already they have been genetically engineered to help clean up spills of toxic mercury. Likely one of the oldest surviving life forms, D. Rad was discovered by accident in the 1950s when scientists investigating food preservation techniques could not easily kill it.
In the picture above: Deinococcus radiodurans grow quietly in a dish.
