“That’s what the ISS means to me: a permanent human presence in space. The orbital perspective open to all of us, through the eyes, the words, the hearts of fellow men and women… it’s all of us turning step-by-step into a space-faring civilization.”
— Samantha Cristoforetti, ESA Astronaut [x]

The Canadian astronaut achieved Internet stardom with his rendition of David Bowie’s “Space Oddity.”
A really great interview of Chris Hadfield was featured on NPR today. If you’re a fan of his (or space in general), you should really check it out.

warp factor nine: a mix for pushing as hard as you can against the laws of physics; for the combustion of energy into immense power; for the speed that makes you dizzy with solar sickness.
With deference to the genius of David Bowie, here’s Space Oddity, recorded on Station. A last glimpse of the World.
Huge thanks in the making of the video to the talented trio of Emm Gryner, Joe Corcoran and Andrew Tidby, plus Evan Hadfield and all at the CSA.

Violent Birth of Supernovae |
A team of astronomers led by the University of Leicester has uncovered new evidence that suggests that X-ray detectors in space could be the first to witness new supernovae that signal the death of massive stars.
Astronomers have measured an excess of X-ray radiation in the first few minutes of collapsing massive stars, which may be the signature of the supernova shock wave first escaping from the star.
The findings have come as a surprise to Dr Rhaana Starling, of the University of Leicester Department of Physics and Astronomy whose research is published in the Monthly Notices of the Royal Astronomical Society.
Dr Starling said: “The most massive stars can be tens to a hundred times larger than the Sun. When one of these giants runs out of hydrogen gas it collapses catastrophically and explodes as a supernova, blowing off its outer layers which enrich the Universe. But this is no ordinary supernova; in the explosion narrowly confined streams of material are forced out of the poles of the star at almost the speed of light. These so-called relativistic jets give rise to brief flashes of energetic gamma-radiation called gamma-ray bursts, which are picked up by monitoring instruments in Space, that in turn alert astronomers.”
Gamma-ray bursts are known to arise in stellar deaths because coincident supernovae are seen with ground-based optical telescopes about ten to twenty days after the high energy flash. The true moment of birth of a supernova, when the star’s surface reacts to the core collapse, often termed the supernova shock breakout, is missed. Only the most energetic supernovae go hand-in-hand with gamma-ray bursts, but for this sub-class it may be possible to identify X-ray emission signatures of the supernova in its infancy. If the supernova could be detected earlier, by using the X-ray early warning system, astronomers could monitor the event as it happens and pinpoint the drivers behind one of the most violent events in our Universe. continue reading
