Planck Mission Releases Images of Galactic Dust 40

davecl writes "The Planck satellite has released its first new science images, showing the large scale filamentary structure of cold dust in our own galaxy. This release coincides with the completion of its first survey of the entire sky a couple of weeks ago. There's lots more work to be done, and more observations to be made, before results are ready on the Big Bang, but these images demonstrate Planck's performance and capability. More information is available on the Planck mission blog (which I maintain)."

Gamma Ray Mystery Reestablished By Fermi Telescope 95

Posted by Soulskill
from the back-to-the-drawing-board dept.
eldavojohn writes "New observations from NASA's Fermi Gamma-ray Space Telescope reveal that our assumptions about the 'fog' of gamma rays in our universe are not entirely explained by black hole-powered jets emanating from active galaxies — as we previously hypothesized. For now, the researchers are representing the source of unaccounted gamma rays with a dragon (as in 'here be') symbol. A researcher explained that they are certain about this, given Fermi's observations: 'Active galaxies can explain less than 30 percent of the extragalactic gamma-ray background Fermi sees. That leaves a lot of room for scientific discovery as we puzzle out what else may be responsible.' And so we reopen the chapter on background gamma-rays in the science textbooks and hope this eventually sheds even more light on other mysteries of space — like star formation and dark matter."

HyperOgga writes "This year we decided to do something completely different. Instead of wasting electricity we devised a way to power our Christmas lights with people power! To do this we attached a handle to our front fence which, when wound, generates electricity through a dynamo. Not only is this environmentally friendly but it's interactive and lots of fun. Everyone in our street seems to like it — every evening we get a steady stream of visitors winding it up and watching the lights glow."

+ - Russian SU-30 Jet Stops in Mid-Air without Stalls->

Submitted by zygote
zygote (134175) writes "From BoingBoing.net
"The fighter can stall from high speed, stopping in less than a second. Then it demonstrates an ability to descend tail first without causing a compressor stall. It can also recover from a flat spin in less than a minute."

So, will the Russians sell it to the Chinese? Why don't we [the U.S.] have one? Or do we...?"
