NASA creates eye-popping 160-megapixel image of our two nearest galaxies (video)

DNP NASA creates surveys of our two nearest galaxies using ultraviolet light video

NASA is determined to bring the final frontier closer than ever -- or at least a small, photographic slice of it. Using NASA's Swift satellite, astrophysicists at Goddard Space Flight Center and Pennsylvania State University were able to create a stunningly detailed survey of the two galaxies closest to us: the Small and Large Magellanic Clouds. The 160-megapixel image was painstakingly stitched together using thousands of smaller photographs captured with Swift's Ultraviolet/Optical Telescope. Rendering the galaxies in UV wavelengths allows researchers to study details unseen in visible light images, like individual stars surrounding the Tarantula Nebula in the LMC (the large pink cluster in the photo above). This high-res mosaic provides ample opportunity to study the life cycles of stars, from birth to death, in detail astrophysicists could previously only dream about. Fancy a tour?

Fraunhofer develops extra-small 1Gbps infrared transceiver, recalls our PDA glory days

Fraunhofer develops extrasmall 1Gbps infrared transceiver, recalls our PDA glory days

Our 1997-era selves would die with envy right about now. Fraunhofer has developed a new generation of infrared transceiver that can transfer data at 1Gbps, or well above anything that our vintage PDAs could manage. While the speed is nothing new by itself -- we saw such rates in 2010 Penn State experiments -- it's the size that makes the difference. The laser diode and processing are efficient enough to fit into a small module whose transceiver is as large as a "child's fingernail." In theory, the advancement makes infrared once more viable for mobile device syncing, with room to grow: even the current technology can scale to 3Gbps, lead researcher Frank Deicke says, and it might jump to 10Gbps with enough work. Along with the usual refinements, most of the challenge in getting production hardware rests in persuading the Infrared Data Association to adopt Deicke's work as a standard. If that ever comes to pass, we may just break out our PalmPilot's infrared adapter to try it for old time's sake.

Alt-week 9.8.12: Moon farming, self powered health monitors and bringing a 50,000 year-old girl to life

Alt-week peels back the covers on some of the more curious sci-tech stories from the last seven days.

Altweek 9812 Moon farming, self powered health monitors and bringing a 50,000 yearold girl to life

Some weeks things get a little science heavy, sometimes it's a little on their weird side, and there's usually a bit of space travel involved, but these week's trend seems to be "mind-blowing." Want to grow carrots on the Moon? We got you covered. How about bringing a 50,000 year-old ancient human back to life? Sure, no biggie. Oh but what about a solar eruption that reaches some half a million miles in height. We've got the video. No, really we have. Mind blown? This is alt-week.
