Although there have been about 800 extra-solar planets discovered so far in our galaxy, the precise masses of the majority of them are still unknown, as the most-common planet-finding technique provides only a general idea of an object's mass. Previously, the only way to determine a planet's exact mass was if it transitshas an orbit that periodically eclipses that of its host star. Former Carnegie scientist Mercedes López-Morales has, for the first time, determined the mass of a non-transiting planet. The work is published by Astrophysical Journal Letters.

Michigan native Susan Brennan was crowned the winner of the eighth annual Toilet Paper Wedding Dress Contest Wednesday (June 27) in New York City.

In the sandy desert grasslands of Namibia in southern Africa, mysterious bare spots known as "fairy circles" will form and then disappear years later for no reason anyone can determine. A new look at these strange patterns doesn't solve the wistful mystery but at least reveals that the largest of the circles can linger for a lifetime.

Sprint will launch its first high-speed 4G LTE networks in Atlanta, Dallas, Houston, Kansas City and San Antonio beginning July 15. Sprint customers in those five metropolitan markets will be able to use Sprint's lineup of 4G LTE smartphones to access the Web at superfast speeds.
"Sprint expects average download speeds of 6 to 8 megabits per second, with peak speeds of 25 Mbps," a company spokesperson said Wednesday. "Upload speeds are expected to be 2 to 3 Mbps."
Sprint also said Wednesday that the addition of Network Vision in U.S. metropolitan markets will bring significant enhancements to the carrier's existing 3G service coverage.
Sprint CEO Dan Hesse said subscribers could expect to experience better signal strength, fewer dropped/blocked calls, faster data speeds, expanded coverage and better overall performance as the improvements rolled out.
"The performance of both the 4G LTE and improved 3G networks are exceeding our expectations and we are pleased with the progress of the entire Network Vision program," Hesse said.
Compatible Handsets Available Now Sprint already sells four smartphone models that will be compatible with the carrier's 4G LTE network. The low-cost LG Viper 4G LTE is priced at $100, while the HTC EVO 4G LTE, the Samsung Galaxy Nexus and Samsung's new Galaxy S III are all priced at $200.
A Sprint spokesperson said Wednesday that the wireless carrier does not plan to introduce any smartphones that include both 4G LTE and WiMAX connectivity options -- though all of the company's 4G LTE handsets will also include 3G. However, Sprint has introduced a tri-mode hotspot accessory from Sierra Wireless that does support 4G WiMAX, 4G LTE and 3G network connections.
Sprint is currently the only top-tier U.S. carrier with no data service throttling, metering or overage fees. On Sprint's new 4G LTE network, also known as the carrier's Network Vision program,...

For all those who can't wait until augmented reality arrives, here's the good news: Google's augmented-reality glasses, the company's visionary headset that overlays endless data on top of what you see in plain old reality, is now available in a special "Explorer's Edition."
The bad news: it will cost $1,500, and will only be available early next year to those U.S. developers who attended this year's Google I/O developers conference.
Sky Divers, Bicyclists But don't despair. The fact that the heads-up display is available at all, even at a high price and to a very limited group, signals that the company believes it has a product that could be, well, looking good.
On Wednesday, Google Chief Executive Sergey Brin showed the prototype headset to attendees of the Google I/O conference, taking place in San Francisco's Moscone West conference center. The limitation on U.S.-only developers is apparently because of various countries' rules about radio-frequency devices.
In addition to layering data on reality, the glasses also offer a built-in video camera. To illustrate the possibilities, Brin introduced a stunt in which four sky divers, wearing the headsets, proceeded to jump from a blimp over San Francisco and land on the roof of the convention center where the conference was being held. The conference goers watched the jump through the parachuters' eyes via the glasses' video transmissions.
As if that wasn't enough to get your "I want one" juices going, video streams were also being transmitted from climbers who rappelled down the side of the conference center, all of whom were similarly fashionable in the new eyewear.
'500 Different Ways' To Go Wrong "This could go wrong in about 500 different ways," Brin cautioned before the stunt took place, but there were no perceived hitches in the demonstration.
For those concerned about how to match such a headset with their outfit, Brin...
