Research says alien life could exist but chances of contact are slim
It's incredibly likely that we aren't alone in the universe, but the chances of us making contact with extra-terrestrials aren't nearly as high. Astrobiologist Amri Wandel seeks to expand on the Drake equation (a formula used to encapsulate the variables scientists looking for E.T.s should consider) by factoring in some of the recent Kepler data. According to Wandel's research (PDF), there are possibly billions of life-sustaining planets in the galaxy, but planets where organisms could exist and planets where life does exist are two different things. These findings come from an advance-release of the International Journal of Astrobiology that should see publication next year.
NASA uses three space telescopes to detect water vapor on Neptune-sized exoplanet
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.
NASA finds Earth-sized planet that could support life
NASA's Kepler telescope has discovered a veritable bounty of alien planets, but none of them have been quite like Earth -- until now. Today, the agency announced that Kepler-186f is the first confirmed Earth-sized planet in the habitable zone of another star. In other words, it's the right size and distance from its sun to have properties similar to our planet -- namely, a rocky composition and liquid water on its surface.
NASA discovers 715 alien planets by looking for them in groups
We know that it's no longer rare to discover alien worlds, but NASA just made it downright commonplace. The space agency has confirmed the existence of 715 exoplanets discovered using the Kepler space telescope, ballooning the number of verified planets to nearly 1,700. Scientists validated the huge number of celestial bodies by looking for targets in batches -- the more objects were clustered together, the more likely it was that there would be multiple exoplanet candidates. The bonanza helps illustrate the frequency of planets among the stars, and it has also uncovered four more potentially habitable worlds. Researchers might not be much closer to finding the Holy Grail of a life-bearing planet, but they'll at least know where to focus their attention.
NVIDIA Titan Black cards bring much improved specs, even crazier prices
That's right, a thousand dollars is just the starting price for the new Titan Black, which surpasses and replaces the original $999 GTX Titan that came out last year. Thanks to a more overclock-friendly version of NVIDIA's "Big Kepler" silicon, card vendors are offering custom-cooled versions of the Titan Black that go way beyond the 889MHz reference design, with monetary premiums to match. EVGA looks to be bringing out a 1GHz "HydroCopper" variant, for example, which will likely fetch in the region of $1,100 -- just reasonable enough, in a twisted sort of way, to make you question whether buying a base card might be selling yourself short. But the Titan Black is about more than just clock speeds. It adopts the gaming-focused features of the $699 GTX 780 Ti, including a full quota of 2,880 stream processors and 240 texture units, and it combines them with the 6GB of GDDR5 and double precision floating point performance that made the first Titan so good at semi-professional GPU compute tasks (just below the level of a Tesla). We haven't seen many reviews yet, aside from one saucy piece of literature that looked at four Titan Blacks side-by-side in SLI mode, but it looks like NVIDA might have finally hit on a solid product for those of us who want to mix business with pleasure.
Early benchmarks suggest NVIDIA's new Tegra chip outperforms Apple and Qualcomm
The graph above comes courtesy of Tom's Hardware and, whichever way you look it, it suggests NVIDIA is onto a good thing. The company's recently announced Tegra K1 processor combines a handful of ARM Cortex-A15 CPUs with a GPU based on the same successful Kepler graphics architecture found in desktops and laptops. The result seems to be a minimum 25 percent lead over the current generation of flagship chips, including Qualcomm's Snapdragon 800 and Apple's 64-bit A7, as measured with 3DMark -- although this may not be an especially fair comparison since we don't know the precise wattage of the Thinkvision's processor (if it's more than a few watts, it shouldn't really be compared to the chip in a smartphone). You'll find a roughly similar pattern in other tests over at the source link, but before you disappear into a new tab here's a couple more disclaimers: Firstly, these scores are based on a Lenovo Thinkvision 28 Android all-in-one (with a lovely 4K panel), which Tom's Hardware was led to believe (but not officially told) contains a K1. Secondly, assuming this is a K1, it's definitely not the 64-bit version; it's not running at NVIDIA's claimed max clock speed of 2.3GHz, and it's almost certainly not using market-ready drivers -- all of which suggests that 2014's crop of Tegra K1-powered tablets could be even more powerful than what we're seeing right now. Update: More benchmark scores are spilling out. They still only relate to graphics, and they rely on a pre-release version of GFXBench, but these numbers would suggest that a Tegra K1 reference tablet can match or even beat the 3D performance of an Intel Haswell laptop with integrated graphics, despite the latter presumably burning many more watts.
GeForce Experience update brings Twitch game streaming
NVIDIA's GeForce Experience may not be tremendously popular with PC gamers, but it's about to get more traction now that its Twitch streaming is finally available in beta. An updated app lets any player with a Kepler-based GeForce card both livestream their sessions and record clips through ShadowPlay. If you're worried about missing special moments, there's a PlayStation 4-like Shadow Mode to automatically capture the last 20 minutes of game time; performance shouldn't be an issue, since dedicated hardware handles all the video encoding. NVIDIA can't promise that everything will be smooth in the beta, but it's already planning to add both a desktop capture mode and new microphone controls. Head to the source links if you're eager to share your virtual escapades with the world.
NVIDIA unveils Tesla K40 accelerator, teams with IBM on GPU-based supercomputing
NVIDIA's Tesla GPUs are already mainstays in supercomputers that need specialized processing power, and they're becoming even more important now that the company is launching its first Tesla built for large-scale projects. The new K40 accelerator only has 192 more processing cores than its K20x ancestor (2,880, like the GeForce GTX 780 Ti), but it crunches analytics and science numbers up to 40 percent faster. A jump to 12GB of RAM, meanwhile, helps it handle data sets that are twice as big as before. The K40 is already available in servers from NVIDIA's partners, and the University of Texas at Austin plans to use it in Maverick, a remote visualization supercomputer that should be up and running by January. As part of the K40 rollout, NVIDIA has also revealed a partnership with IBM that should bring GPU-boosted supercomputing to enterprise-grade data centers. The two plan on bringing Tesla GPU support to IBM's Power8-based servers, including both apps and development tools. It's not clear when the deal will bear fruit, but don't be surprised if it turbocharges a corporate mainframe near you.
NASA halts efforts to repair Kepler space telescope
It's had a good run, but it seems like NASA's Kepler telescope is down for the count -- the space agency says it has stopped repair efforts. The 0.95 meter diameter space telescope launched four years ago, tasked with seeking out Earth-sized planets suitable for habitation. All was going well until the rig's gyroscopic reaction wheels began to fail, robbing it of the precision aim needed to continue its task. After months of testing, NASA has concluded that it won't be able to restore the telescope to full working order. That doesn't mean the mission is at an end, however -- NASA still has to sort troves of previously collected data, thumbing through over 3,500 exoplanet candidates to add to the 135 celestial bodies Kepler has already identified. The hardware may one day see a second life too, as engineers attempt to assess what can be done with the remaining two reaction wheels and the telescope's attitude control thrusters. Without significant (and now abandoned) repair efforts, Kepler will never be precise enough to continue its primary mission, but NASA is hopeful it will eventually find a new purpose.
Nvidia Kepler mobile GPU 'Project Logan' supports Unreal Engine 4
Nvidia has unveiled its new mobile graphics processor, built on the same Kepler architecture found in its latest PC graphics cards. Dubbed Project Logan, this new chip supports Unreal Engine 4 and, according to comments from Epic Games CEO Tim Sweeney, will empower mobile devices with "the same high-end graphics hardware capabilities exposed via DirectX 11 on PC games and on next-generation consoles." Right, it's not just Unreal Engine 4 – Nvidia says Project Logan supports popular graphics standards Open GL 4.4 and Direct X 11, and uses one-third the power consumption of GPUs found in "leading tablets, like the iPad 4." Project Logan runs at 2.2 teraflops, with more raw processing power than can be found in the PS3's GPU. Above, you can see a video demo of Nvidia's faux-face "Ira" rendered on Project Logan in real-time, and embedded past the break you'll find Nvidia's "Island" demo running on the mobile chip. Project Logan is still in the prototyping phase, so don't expect to see it in the wild anytime soon.
NVIDIA puts Project Logan on display at SIGGRAPH: Kepler gets cozy on a mobile chip (video)
We've known about NVIDIA's plans to bring Kepler to mobile for a few months now, but the component maker offered up an early glimpse of the SoC at SIGGRAPH this week. In terms of power usage, Logan's use of Kepler architecture translates to one-third the consumption of GPUs currently running in devices like the Retina iPad while wrangling the same renders. Of course, it does have a healthy amount of room to scale up from there for much beefier tasks. The silicon also supports the just announced OpenGL 4.4, OpenGL ES 3.0 and Microsoft's DirectX11. So, what does all of that translate to in terms of graphics? Project Logan enables the use of advanced rendering and simulation techniques to construct imagery -- things like tessellation, advanced lighting and physical simulation, just to name a few. In other words, this allows for PC and console-quality graphics to get cozy on mobile devices. For a look at chip in action, venture on past the break where the Ira demo that was unveiled earlier this year on GeForce GTX Titan GPU-packing desktop is now running on a Logan-equipped mobile device. %Gallery-194493%
NVIDIA unveils GeForce GTX 760, brings modern Kepler down to $249 (video)
NVIDIA has been gradually lowering the base pricing for its desktop GeForce 700 series, but few outside of the hardcore gamer set would say the $399 GTX 770 was affordable. Enter the GeForce GTX 760: the Kepler-based chipset supports all the visual effects of its faster cousins, but at a more palatable $249 target price. Although it won't rival the 770 in performance, it offers more bang for the buck than the GTX 660 it's built to replace: the GTX 760 carries more processing cores (1,152 versus 960) and more memory bandwidth (192GB/s versus 144GB/s) while maintaining similar clock speeds. It can even punch above its weight class, as it's reportedly up to 12 percent faster than the $299 GTX 660 Ti. Should that balance of price and performance sound especially sweet, you can pick up a GTX 760 board today from the likes of ASUS, EVGA, Gigabyte and others. Several PC builders, such as Falcon Northwest, Maingear and Origin PC, are also equipping their machines with the new mid-tier graphics from day one.
NVIDIA to license graphics tech to other companies, starting with Kepler
To use NVIDIA's graphics technology, you've typically had to buy gadgets using NVIDIA chips -- good for the company's bottom line, but not for influencing the industry as a whole. The firm is expanding its ambition today with plans to license some of that technology on a broader scale. Beginning with the Kepler architecture, other firms can use NVIDIA's GPU cores and graphics-related patents for their own processors and chipsets. The deal could affect a wide range of hardware, but it mostly pits NVIDIA against the likes of Imagination Technologies: a system-on-chip designer could integrate a Logan-based GPU instead of the PowerVR series, for example. While it will be some time before third-party silicon ships with NVIDIA inside, it's already clear that the company's in-house design is now just one part of a larger strategy.
NVIDIA reveals GeForce GTX 700M series GPUs for notebooks, we go eyes-on
We've already seen a couple of new desktop GTX cards from NVIDIA this month, and if the mysterious spec sheet for MSI's GT70 Dragon Edition 2 laptop wasn't enough of a hint, the company's got some notebook variants to let loose, too. The GeForce GTX 700M series, officially announced today, is a quartet of chips built on the Kepler architecture. At the top of the stack is the GTX 780M, which NVIDIA claims is the "world's fastest notebook GPU," taking the title from AMD's Radeon HD 8970M. For fans of the hard numbers, the 780M has 1,536 CUDA cores, an 823MHz base clock speed and memory configs of up to 4GB of 256-bit GDDR5 -- in other words, not a world apart from a desktop card. Whereas the 780M's clear focus is performance, trade-offs for portability and affordability are made as you go down through the 770M, 765M and 760M. Nevertheless, the 760M is said to be 30 percent faster than its predecessor, and the 770M 55 percent faster. All of the chips feature NVIDIA's GPU Boost 2.0 and Optimus technologies, and work with the GeForce Experience game auto-settings utility. The 700M series should start showing up in a host of laptops soon, and a bunch of OEMs have already pledged their allegiance. Check out a video with NVIDIA's Mark Avermann after the break, where he shows off a range of laptops packing 700M GPUs, and helps us answer the most important question of all: can it run Crysis? (Or, in this case, Crysis 3.) %Gallery-189806%
Plex releases 3.0 overhaul for Android, 3.2 update for iOS
Plex's Android app revamp has been brewing for awhile, but it's at last ready: the 3.0 app is out of beta and available for everyone. The remake provides a much more polished interface, PlexSync support and speedier access to large libraries. It's facing a rocky start, however. The initial 3.0 release required a myPlex account and didn't include a remote control widget, and those have only just been fixed with a quick follow-up patch. We wouldn't lean on earlier versions of Android, regardless of what features you like -- the interface rewrite cuts off support for OS releases before Android 3.2. iOS users aren't left out of the upgrades. Version 3.2 isn't as dramatic a makeover, but it does offer tangible improvements over 3.1 that include the Android version's faster media access and fixes for conspicuous PlexSync bugs. Quick updaters even get a reward for their trouble: the 3.2 client lets the iOS app serve as a remote playback target for other Plex-equipped devices. Whichever platform you prefer, the app update (or a fresh $5 copy) is waiting at one of the source links.
NVIDIA releases GeForce GTX 780 for $649, claims more power with less fan noise
It's well over a year since the GTX 680 came out, but given how that card was a strong contender it may feel too early for an upgrade. NVIDIA knows the score, which is why it's made a particular point of pitching this year's card at owners of the GTX 580 instead. Upgraders from that GPU are pledged a 70 percent lift in performance, which is about double the gain a GTX 680 owner would see. On the other hand, something more people might notice -- if NVIDIA's slides prove to be accurate -- is a 5dBA drop in noise pollution, as well a new approach to fan control that attracts less attention by varying revs less wildly in response to load. This is surprising given that most of the extra performance in this card stems from more transistors and greater power consumption, but that's what we're told. Feel free to hold out for our round-up of independent reviews or read past the break for further details.%Gallery-189136%
NASA's Kepler discovers three potentially habitable planets
NASA's Kepler telescope has discovered three "super-Earth-size" exoplanets that are close enough to their stars to make them possibly suitable for water. Two of the planets (Kepler-62e and Kepler-62f) orbit a K2 dwarf estimated to be around 7 billion years old. Measuring at two-thirds the size of our sun, this cosmic lantern is orbited by a total of five planets, three of which are too close to be habitable for life. Kepler-69c, the biggest of this newly discovered trio is estimated to be 70 percent larger than Earth and takes 242 days to revolve around its sun-like star Kepler-69. While there's great excitement surrounding these new findings, this isn't the first time we've spotted a potentially habitable planet. A little over a year ago Kepler discovered Kepler-22b, an exoplanet about 600 light-years away from Earth believed to be covered in liquid. Like their predecessor, NASA has yet to determine if these newfound planets actually have water or a rocky composition. Until then, Ridley Scott might want to hold off on naming them as locations for his sequel to Prometheus.
Next-gen NVIDIA graphics will make today's tablet games look like 'vintage 1999' (video)
Jen-Hsun Huang took to the stage during NVIDIA's recent investor day to show off an interesting video, which VentureBeat fortunately managed to capture. It's embedded after the break and consists of two contrasting parts: footage of a current "state of the art" iPad game that we don't immediately recognize, and then footage of Battlefield 3 running on unknown tablet hardware containing a next-gen Kepler mobile GPU -- possibly Logan. We're not sure Huang picked the strongest iPad example for comparison, but it's fair to say the difference is immediately obvious, with the Kepler section bearing dynamic lighting, particle effects, shadows and HDR lighting that appear to deliver a more console-level experience. All in all, it potentially looks like an NVIDIA chip to rival the coming breed of AMD Temash tablets, which we've already seen running Dirt Showdown at low wattages.
NVIDIA details how its Jetson development kit creates smart, seeing cars
Developing a high-end in-car infotainment system can present challenges that don't exist in other platforms -- you're juggling core car systems, a myriad of sensors and media playback in a testbed on wheels. NVIDIA has just explained how it's uniting those elements with its new, lengthily-titled Jetson Automotive Development Platform. While it looks like a single-DIN car stereo laid bare, the configurable kit incorporates a Tegra processor (for usual infotainment functions), multiple car-friendly interfaces and a Kepler-based graphics chipset that can power car detection, lane departure and other computer vision systems by using CUDA or OpenCV code. The net effect should be a much simpler development process: automakers can consolidate some of their test hardware in one Jetson unit that they can upgrade or swap out if newer technology comes along. NVIDIA isn't naming the handful of designers and suppliers that are already building car electronics using Jetson, although history offers a few possible candidates.
NVIDIA updates its mobile roadmap: Logan and Parker, mobile SoCs packing Kepler and Maxwell GPUs
Thought the new Tegra 4i was the bees knees when it we saw it last month? Well, NVIDIA gave us a bit more info on the next steps in the Tegra roadmap, Logan and Stark Parker. It turns out that these next two mobile platforms will both utilize NVIDIA's CUDA technology, with Logan packing a Kepler GPU and Parker running a Project Denver 64-bit ARM CPU and a next-gen Maxwell GPU. Logan arrives early next year, while Parker won't be in devices until sometime in 2015.
