Interactive Planetarium Celestia serves as a planetarium – for an observer on any celestial object. You can easily navigate to any world and land on its surface. When used as a planetarium, Celestia shows accurate positions of solar system objects in the sky. You can switch labels and other supporting features on and off with hotkeys, or zoom in and out on an object of interest, for example Jupiter’s system of moons.
A new study from South Dakota State University reveals how grapevine canes can be converted into plastic-like material that is stronger than traditional plastic and will decompose in the environment in a relatively short amount of time. The need for biodegradable packaging material has never been higher. Currently, most packaging is "single use" and is made with plastic materials, derived from nonrenewable sources like crude oil that take hundreds of years to decompose in the environment. On t
The holidays are still months away, but if you want the best deals on a new laptop or smartphone, you should probably start shopping now. According to a new CNET survey, nearly half of shoppers aren't waiting until Black Friday and Cyber Monday to shop. Instead, they're shopping for tech for the holidays months early to beat potential rising prices and shortages. But is shopping early the best strategy? I spoke with CNET's resident tech and shopping experts to find out. Don't miss any of our u
Tomorrow, Apple is set to launch iPadOS 26: an incredible new overhaul for the iPad. It brings a Mac-like windowing system, a new Menu bar, the ability to pin folders to the dock, and much, much more. It makes the iPad feel like a computer for the very first time, making it a better time than ever to pick up a new iPad to pair with the new release. Luckily, unlike some previous iPad software releases – all iPads running iPadOS 26 will support the new windowing and multitasking systems. Obvious
The Apple iPhone 17 event last week delivered on all of the rumors we read ahead of the show. The company announced the iPhone 17 lineup, the all-new iPhone Air and several other devices. (Check out Engadget's liveblog of the event for full details.) In addition to finally seeing the new hardware, Apple confirmed after the event that we'll be able to download the final versions of iOS 26 and iPadOS 26 on Monday, September 15. (That's when all of Apple's other operating system updates hit, too.)
Doctors have developed special eye drops for people with longsightedness that could replace the need for reading glasses or surgery. Hundreds of millions of people worldwide have presbyopia, which is when the eyes find it difficult to focus on objects and text up close. Glasses or surgery can usually resolve the problem but many find wearing spectacles inconvenient and having an operation is not an option for everyone. Now experts say the solution could be as simple as using eye drops twice a
The Irrlicht Engine supports 5 rendering APIs, which are 4 more than most other 3D engines do: Direct3D 9.0 OpenGL 1.2-4.x The Irrlicht Engine software renderer . . The Burningsvideo Software Renderer A null device. When using the Irrlicht engine, the programmer needs not know, which API the engine is using, it is totally abstracted. He only needs to tell the engine which API the engine should prefer. There are three reasons why the engine not only focuses on one API: Performance . Some gra
Alicante Alicante's rapid transit system is called TRAM, which is a train-tram and is operated by FGV, owned by the Valencian regional government. This system has an underground line in the city center, with three stations on it. The layout consists with one or two mezzanines on level -1 and two side or one island platforms at level -2. Luceros and Mercado stations have direct connection with the underground parking lots, which are located above the TRAM tunnel. Amsterdam Metro services in Amst

SpaceX’s has been partnering with mobile carriers like T-Mobile to offer its satellite internet service Starlink to extend the reach of cell networks. But, according to a report from the Washington Post, the company has ambitions to be more than just a partner. Following a major purchase of wireless spectrum earlier this week, it appears everyone is expecting Elon Musk’s company to get into the wireless network business for itself. On Monday, it was reported that SpaceX was finalizing a deal wi
Apple unveiled the iPhone 17 at its "awe dropping" event along with the super skinny iPhone Air and the powerful iPhone 17 Pro/17 Pro Max. You may be wondering whether to get the new shiny standard iPhone 17 or buy last year's iPhone 16 which is $100 less. To help with that decision, here's a breakdown of how the two handsets compare. The iPhone 17 starts at $829 (or $799 if you activate with a carrier), the same as the iPhone 16 when it came out -- with the caveat that the iPhone 17 starts wit

Right-wing internet personality and Turning Point USA cofounder Charlie Kirk was shot and killed on Wednesday during a speaking engagement at Utah Valley University in Orem, Utah. After a chaotic 24-hour manhunt, the FBI named 22-year-old Utah resident Tyler Robinson as a suspect in the murder. As polarization and political violence continues to increase in the US, a new platform from the Public Service Alliance is offering tools like data-removal services and threat monitoring to public servan
As generative AI slop is threatening to turn Hollywood on its head, not everybody in the industry is enthusiastic about the tech. In a hilarious counter to a fan's AI-generated image of actor Brandon Sklenar dressed as the DC Comics' Batman, DC Studios filmmaker and "Superman" director James Gunn quipped in a Threads post that "it would be weird to cast an AI Batman with a 14 inch arm." Gunn was alluding to the AI-generated Batman's unnaturally short appendages, pointing out the AI's failure t
Rita El Khoury / Android Authority TL;DR An Android Authority teardown has uncovered just how Quick Share will work for iPhones. Android owners can share a QR code with iPhone users to let them download files. However, files shared with iPhone users via Quick Share will first be uploaded to the cloud and retained for 24 hours. We’ve known since last year that Google is working on bringing Quick Share to iOS and MacOS. We recently discovered more evidence of the feature coming to iPhones, as
Ryan Haines / Android Authority When Nothing first switched from its original Glyph Interface to the new Glyph Matrix on the Phone 3, I have to say I was underwhelmed. Sure, the LED-filled circle looks cool and promises a new way to interact with your phone, but I couldn’t shake the fact that it felt more like a gimmick than the light-up strips. It packed more toys than tools, and I couldn’t make myself use it enough. But now, I’ve found an app that changes things. It’s called Glyphify, and it
Apple just wrapped up its iPhone 17 launch event last week. While that was a jam-packed (and incredibly fast-paced) keynote, the company still has another 10 product launches in the short term, with half of them launching by the end of the year. Remaining 2025 launches There were a number of product launches anticipated at this year’s September keynote that didn’t quite come to fruition. Those products should still launch by the end of the year though, according to Bloomberg’s Mark Gurman – wi
Apple is reportedly working on a new MacBook Pro refresh, as they tend to do almost every year. This refresh is quite minor, but if you’re in the market for a new laptop, we’ll be breaking down everything you need to know about the next MacBook Pro update. What’s new As always, these new MacBook Pro models will come with a new generation of Apple Silicon. That means we’ll see the introduction of M5, M5 Pro, and M5 Max. These chips will still be based on TSMC’s 3nm process, specifically N3P, t
Jason Hiner and Nina Raemont/ZDNET Follow ZDNET: Add us as a preferred source on Google. Apple just announced the new iPhone 17 Pro at its Awe Dropping live event, and it comes with some pretty substantial upgrades both in terms of design and capabilities. We're talking longer battery life, more onboard memory, a bigger and brighter screen, and an improved camera system. If you've got an iPhone 15 Pro, your device is already two years old. It may look like a good time to spring for the new

Sabrina Ortiz/ZDNET Follow ZDNET: Add us as a preferred source on Google. ZDNET's key takeaways Apple just launched its iPhone 17 Pro. The new model includes some enticing upgrades. I have had the 16 Pro for one year, and might trade it in. While most people choose to wait several years before upgrading their iPhones, that's a bit more challenging for tech aficionados like myself. I really wanted to hold out on upgrading my daily driver, the iPhone 16 Pro, but after watching the launch e
The IBM Personal Computer was launched on 12 August 1981. Designed by an IBM team in Boca Raton, Florida led by Philip Don Estridge and William C. Lowe. That first PC, given the less than charismatic designation as the ‘Model 5150’, and its successors quickly set the standard for personal computing, first in business and then in homes. So much so that they became known as just ‘PCs’. But the PC was never an true ‘IBMer’, the colloquial term used for IBM employees. Wait a moment! The IBM PC. D

Posted on: September 13, 2025 | at 09:30 AM Follow @popovicu94 I recently implemented a minimal proof of concept time-sharing operating system kernel on RISC-V. In this post, I’ll share the details of how this prototype works. The target audience is anyone looking to understand low-level system software, drivers, system calls, etc., and I hope this will be especially useful to students of system software and computer architecture. This is a redo of an exercise I did for my undergraduate cours
Engineers from Ohio State University are developing a new way to power rocket engines, using liquid uranium for a faster, more efficient form of nuclear propulsion that could deliver round trips to Mars within a single year. NASA and its private partners have their eyes set on the Moon and Mars, aiming to establish a regular human presence on distant celestial bodies. The future of space travel depends on building rocket engines that can propel vehicles farther into space and do it faster. Nucl
At long last, we have a release date for The Witcher season four: October 30. On Saturday night, Netflix released a first look at the new season, which sees Liam Hemsworth as the new Geralt of Rivia after Henry Cavill bowed out. We see Geralt’s still doing his monster-slaying thing, and the clip goes out of its way to assure Hemsworth’s got the look and action chops to carry the show for its final two seasons. Like the Cavill-led era, this new adventure for Geralt will span eight episodes, and

It’s been a few years since Netflix confirmed that Liam Hemsworth would be taking over as Geralt of Rivia in the live-action Witcher series. And while we caught a brief glimpse of him in action last year, the first proper clip from season 4 of the show reveals just how Hemsworth will be inhabiting the role — including his take on Geralt’s signature growling voice.
