MWC 922: The Red Square Nebula

What could cause a nebula to appear square? No one is quite sure. The hot star system known as MWC 922, however, appears to be embedded in a nebula with just such a shape. The featured image combines infrared exposures from the Hale Telescope on Mt. Palomar in California, and the Keck-2 Telescope on Mauna Kea in Hawaii. A leading progenitor hypothesis for the square nebula is that the central star or stars somehow expelled cones of gas during a late developmental stage. For MWC 922, these cones happen to incorporate nearly right angles and be visible from the sides. Supporting evidence for the cone hypothesis includes radial spokes in the image that might run along the cone walls. Researchers speculate that the cones viewed from another angle would appear similar to the gigantic rings of supernova 1987A, possibly indicating that a star in MWC 922 might one day itself explode in a similar supernova. via NASA http://go.nasa.gov/1nyAe5S

Sacred Swim

A quiet morning at Dashashwamedh Ghat, the main ghat in Varanasi, India, on the banks of the Ganges River, afforded Your Shot member Raja Subramaniyan an image that could project the feel of the moment: a lone visitor “taking the holy bath.” The ghats, especially this one, are often full of pilgrims and tourists alike, but of this photo the photographer writes, “I loved the atmosphere of the Dashashwamedh Ghat on that day—beautiful sunrise with warm light, the mist effect, the arrangement of boats.”

Subramaniyan’s shot was recently featured in the Daily Dozen.

Cycling Has Moved From Actual Doping to ‘Mechanical Doping’

After a century of pumping themselves full of all sorts of performance-enhancing (and other!) drugs, it appears that at least one pro cyclist has found an easier way to cheat: hiding a motor inside the bicycle frame.

FCC Allows Limited Testing of Controversial Unlicensed LTE Technology

Depending on who you talk to, LTE-U
—the term given to using cellular LTE technology to transmit in unlicensed airwaves—is either the future of communications, or a terrible idea that will wreck Wi-Fi. The FCC is studiously not taking sides in the argument, but is allowing further testing.

Watch The Navy’s 11th Littoral Combat Ship Plunge Sideways Into The Frigid Menominee River 

Ships launches are sometimes wild affairs, and depending on the method used, making a big splash can be part of the drill. The Freedom Class of Littoral Combat Ships do just that, being slid off the pier where they were built sideways. On Jan. 30, the soon-to-be USS Sioux City was the sixth LCS to take this grand plunge.
