NASA uses three space telescopes to detect water vapor on Neptune-sized exoplanet

byMariella Moon|@mariella_moon| 7 hours ago

NASA has been discovering one exoplanet after another these days, but its scientists have to look a lot closer if they want to see more details, such as the planets' color or whether they have water. That's exactly what the agency did while observing HAT-P-11b -- by combining the power of three space telescopes, scientists have found clear skies and water vapor on the atmosphere of the Neptune-sized exoplanet. NASA observed the distant world while it was crossing its solar system's sun using one of Hubble's wide field cameras. Water vapor typically absorbs starlight during that process, and it's that light that reaches our telescopes. In order to confirm whether it's actually water vapor (mixed with hydrogen gas and other molecules), the scientists compared Hubble's data to visible-light data collected by Kepler and Spitzer light data taken at infrared wavelengths.

To note, this isn't the first time scientists found water vapor on exoplanets. But, they were all more akin to the size of Jupiter, since it's tough observing smaller ones like this from afar, especially since most of them seem to have cloudy atmospheres. This particular discovery gives NASA hope that it can work its way down to even smaller planets, until it can effectively observe Earth-sized rocky worlds in other solar systems.

Record-breaking processed three tonnes of force in magnet the size of a golf ball

BYSteve Dent @Stevetdent1 hours ago

University of Cambridge scientists have a ten year old superconducting broken record by packing a 17.6 Tesla magnetic field in a golf ball-sized lump of Crystal--equal to about three tons of force. The team uses high temperature superconductors that work at-320 degrees F or so--not exactly balmy, but less than the-460 degrees F required for regular superconductors frigid. With zero resistance, superconducting materials can be up to 100 times more power than copper wires, but the resulting magnetic fields create massive internal forces. Since the cuprate materials used for the record so fragile as dried pasta, they can actually explode under the strain. To get around it, the team modified the material microstructure and ' shrink-wrapped ' in stainless steel. That the largest magnetic field ever caught in a standalone material at any temperature, produced according to the team. The research may eventually lead to more secure and efficient transfer of power, better scanners and Yes, suspended monorails.

Three reminds Vodafone patrons they can still cancel their contracts for free

BYJamie Rigg @jmerigg5 hours ago

Vodafone decided in May to tell everyone it was committed to never increasing prices mid-contract, and Three was quick to highlight its identical policy -- one that's shared across the industry thanks to Ofcom regulations that state any customer can ditch their contract without penalty should pricing go up during the term. Vodafone then announced that same month it would be upping the cost of charges incurred when going above your monthly allowance of calls, texts and data. While the increases don't technically affect monthly contract pricing, they still meet the Ofcom criteria thats allows customers to exit their contract scot-free. And, with the new overage charges coming into effect on June 28th, anyone that wants to take advantage of the easy out needs to tell Vodafone they're leaving within the next few days.

Ever the opportunist, Three has taken to its blog to remind Vodafone customers they still have time to "break up" with their current carrier. Employing the comedic talents of Rufus Hound, Three has even commissioned an emotional parting letter you can use as a template to terminate your contract. Sure, it's try-hard, please-go-viral PR complete with a recommended Twitter hashtag, but you'd be forgiven for getting a kick out it anyway. And, to be fair, the template will save you a bit of time if you're too lazy to write a break-up letter of your own.

The three faces of Android Wear, compared

BYJon Fingas @jonfingas4 hours ago

Google made much ado about the debut of Android Wear at its I/O conference keynote, and few would doubt that this is a potentially sea-changing move in the wearable space. However, the company didn't do much to address the differences between the first smartwatches using its brand-new platform. How are you supposed to know which wearable suits you? That's where we can help out. We've taken a good look at this first batch -- LG's G Watch, Motorola's Moto 360 and Samsung's Gear Live -- to see how they compete. And it's a closer fight than you'd think. While all three have their charms, you'll be making some sacrifices no matter which model you choose.

LG G Watch

In many ways, LG's G Watch is the template for Android Wear, the basic design that everyone will try to equal or beat. It has an unassuming steel chassis, a square display and a distinct lack of party tricks. Those aren't necessarily knocks against it -- if you'd rather not be flashy, this is the smartwatch for you. It also has a bigger battery than the Gear Live (400mAh versus 300mAh), so you could be looking at a longevity champ.

Having said all that, there are some worrisome points. Besides the fairly plain looks, it has a lower resolution (280 x 280), a thicker body (10mm) and a higher price ($229) than the Gear Live; if you only care about the raw numbers, you're paying more to get less. And since LG's rivals haven't provided firm battery life estimates, we won't know if the G Watch's claimed 36-hour runtime is above-average for some time to come.

Samsung Gear Live

Design-wise, Samsung's Gear Live strikes a balance between the plain G Watch and the posh Moto 360. It's slimmer (8.9mm), sharper-looking (320 x 320) and more stylish than LG's model, but not nearly the conversation starter that Motorola's timepiece promises to be. It's the only game in town if you're a fitness maven, though; like its Gear 2 siblings, there's a heart rate sensor that will let you know if your exercise is on track. At $200, the Gear Live may also be the cheapest of the lot.

You may want to see how the battery life works out in real life before you pull the trigger. Samsung is touting "all-day" usefulness, but it's not saying how many hours you'll get in practice. There's a distinct possibility that LG or Motorola could come out ahead.

The Moto 360 has been the most buzzed-about Android Wear watch to date, and for good reason. In terms of style, there's no contest -- the round display and luxurious materials make this not only the best-looking Android Wear device so far, but also the only one that could pass as a conventional watch at first glance. Motorola has also been far more eager to embrace third-party watch faces, some of which already use the circular layout to good effect. So long as you don't mind a huge frame that would make Flavor Flav proud, it could easily be the frontrunner.

That is, so long as the specs pan out. Most everything about the Moto 360's hardware is currently a mystery -- Motorola still isn't willing to divulge the battery life, performance, price or storage. There are hints that the exotic form factor could lead to a price tag around $249 or higher, and that big screen may be power-hungry. If you're reluctant to risk making any major compromises in the name of fashion, we'd recommend waiting until more details emerge this summer.

Titanfall nears 1 million sold in three weeks

Many looked at Titanfall
as being the first tentpole game for the Xbox One, but how many people actually bought it? It turns out 925,000 units were sold through for the quarter, according to publisher Electronic Arts' latest earnings call. Unfortunately, Chief Operating Officer Peter Moore was citing NPD numbers and those don't include digital or world-wide sales, and thus copies bought via EA's Origin PC service or from the Xbox One's dashboard don't factor into that tally. The Xbox 360 version? It's "off to a great start," but Moore didn't go into specifics. Back in April, the NPD reported that the mech game was a top-seller for March and the second-best performing game for the Xbox One -- seeing hard numbers gives a better picture for how well gaming is doing on the new consoles. While Titanfall's numbers are impressive, it's worth remembering that Infamous: Second Son sold more than that on a single platform globally (Titanfall's numbers combined the PC and Xbox One sales) in nine days both physically and via digitally distributed copies. 0 Comments Share _when_.eng("eng.perm.init")
