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.

This key iPhone 17 Pro rumor didn’t come to fruition, but there’s a good reason for it

With iPhone 17 Pro, there was one major rumor that a lot of Apple fans were looking forward to this year: reverse wireless charging. After all, with the new glass window with a centered Apple logo – it looked like a perfect opportunity for this new feature. Our batteries are also larger than ever. Yet, the Apple Event came and went – and there was no reverse wireless charging. While this is certainly disappointing, there’s a good reason for it not arriving, and I’ll delve into that. Magnets ca

Our favorite budget wireless earbuds are back on sale for $45

The Anker Soundcore Space A40 wireless earbuds are back on sale for a record-low price of $45 a 44 percent discount. These earbuds remain our top pick for best budget wireless earbuds. The most significant feature on the A40 earbuds is the inclusion of active noise cancellation (ANC), which is almost unheard of at this price point. It's not the most sophisticated ANC, but it does sufficiently reduce constant rumbling background noise like on a plane. The built-in mic that's used for transparenc

The Value of Bringing a Telephoto Lens

They usually aren't light, and they certainly aren't small, but the unique perspective a telephoto lens brings makes it an indispensable part of your kit, even when traveling. Let's review some shots taken with a telephoto to see how we can justify its size and weight. Avoiding Distractions In some cases, distracting buildings or people may be unavoidable. However, a telephoto can help eliminate those distractions and bring your subject, in this case the clouds and mountains, front-and-center:

What Are Ebike ‘Classes’ and What Do They Mean?

Over the past few years, electric bikes have skyrocketed in popularity (conscious decision not to use the word exploded there), with some estimates saying that ebike sales in the US grew tenfold over the last decade. Whether you are in the market for your first ebike or are borrowing one from your local lending library, you might be wondering what an ebike’s class denotes. There are three designations of ebikes in America—Class 1, Class 2, and Class 3—that are defined by a small handful of char

Chinese EV players take fight to legacy European automakers on their home turf

Xpeng CEO He Xiaopeng speaks to reporters at the electric carmaker's stand at the IAA auto show in Munich, Germany on September 8, 2025. Arjun Kharpal | CNBC Germany this week played host to one of the world's biggest auto shows — but in the heartland of Europe's auto industry, it was buzzy Chinese electric car companies looking to outshine some of the region's biggest brands on their home turf. The IAA Mobility conference in Munich was packed full of companies with huge stands showing off thei

Close the loop: analytics that teach your chatbot to fix itself

Many chatbots stall for the same reason. Unanswered questions build up and nothing changes. Teams ship a release and move on. Users try again and give up. The way out is simple. Treat every miss as a signal. Capture it in a standard way. Decide whether it was noise or a real gap. Turn real gaps into small updates in guardrails or knowledge. Run that loop every week. Measure how fast it moves. Results improve without bigger models. Start with lean instrumentation Analytics only works if the tra

The Free Ride for EVs in the Carpool Lane Is Coming to an End

A rough year for electric vehicle adoption just got a little rougher for owners in some parts of the US. Starting next month, EVs will no longer be able to ride in the fast lane in California, after the US federal government and Congress failed to reauthorize a popular program that has given hybrid and electric vehicles access to state carpool lanes—and worked to promote the sale of electrics for more than 25 years. Under the program, California drivers with qualifying electric, plug-in hybrid,

Ram ends EV pickup truck plans

The all-electric Ram 1500 REV pickup truck is dead. Long live the extended-range Ram 1500 REV (once called the Ramcharger). Stellantis, the parent company of Ram, said Friday that it will no longer develop a battery-electric full-size pickup. The company cited low demand for full-size battery-electric trucks as the primary reason, according to a statement sent to TechCrunch and posted on its website. “As demand for full-size battery-electric trucks slows in North America, Stellantis is reasses

Man gets over 4 years in prison for selling unreleased movies

A Tennessee court has sentenced a Memphis man who worked for a DVD and Blu-ray manufacturing and distribution company to 57 months in prison for stealing and selling digital copies of unreleased movies. 37-year-old Steven R. Hale was charged in March with selling ripped DVD and Blu-ray discs of movies before their release. Prosecutors stated at the time that Hale had stolen numerous discs of movies that were being prepared for commercial distribution in the United States between February 2021 a

Full Moon: Seestar S50 vs. Samsung S25

The full moon is one of those sights that almost begs to be photographed, no matter what camera you’re using. Most of the time, that means a smartphone, and to be fair, modern phones are excellent at handling bright subjects like the moon. Of course, a telescope should reveal far more than a phone camera, but I wanted to see just how big that difference really is. So last night, under clear skies, I took two photos. Seestar S50 smart telescope : designed for astrophotography, with a larger ape

When Is the Earliest Day You Can Get an iPhone 17?

Now that we know all the details about the iPhone 17, iPhone 17 Pro and the new iPhone Air, it's time to ask the most important question: when can we get them into our hands? Preorders for all of this year's iPhone models begin Friday at 5 a.m. PT. Then begins what feels like an endless slog before the new phones finally arrive (which, every year, is punctuated by the arrival of iPhone cases several days beforehand, as if to taunt us). So when, exactly, can we expect to see our favorite deliver

Tonverk is Elektron’s new polyphonic sample mangler and groovebox

Elektron has built a cult-like following over the years with its unique and, at times, esoteric take on electronic musical instruments. On paper, Tonverk is a seemingly over-powered sampler that continues that tradition. It’s the rare piece of hardware capable of creating multisampled instruments on its own. It turns a single sample track into a nesting doll of multiple samples. And it’s loaded with an absolutely absurd amount of routing and audio processing features. Tonverk is certainly capabl

MotoE, the electric bike world championship, is going on hiatus due to lack of interest

The International Motorcycling Federation (FIM) and MotoGP are putting the MotoE electric bike world championship on hiatus following the 2025 season. The organizations cite a lack of viewership and an electric performance motorcycle market that "has not developed as expected." "Today we announce the suspension of the FIM MotoE World Championship," FIM President Jorge Viegas said in a statement. "Despite all the best efforts to promote this innovative category together with (MotoGP rights holde

Apple’s faster MagSafe Charger can now charge other phones at 25W

The new charger, which was first leaked last June through Taiwan’s National Communications Commission’s website, is now available through Apple’s online store with a 1-meter USB-C cable for $39, or a 2-meter cable for $49. Apple introduced 25W wireless charging with the iPhone 16 ahead of the Qi2.2 specification being officially introduced early this year, which is why the faster rate was only available when using Apple’s own wireless charger. Now that the iPhone 17 lineup is Qi 2.2 compatible

This small Android flagship could put the iPhone 17’s dual cameras to shame

Hadlee Simons / Android Authority TL;DR A Vivo representative has revealed details of the upcoming X300 series. The Vivo X300 is confirmed to be smaller than last year, with the same dimensions as the Vivo X200 Pro Mini.

Arc gets its first major order for electric tugboats worth $160M

If you’ve heard of Arc Boats, the Los Angeles startup founded in 2021 by former SpaceX employees, it’s likely because you’ve seen its sleek sport boats. But the company’s also been pushing into the far less glamorous world of tugboats, and now has its first big order worth $160 million. The company announced Wednesday it has signed a contract of that value with Curtin Maritime, a tug and barge operator. The new hybrid-electric tugs are expected to hit the waters around the Los Angeles port in 2

I swapped my favorite Linux desktop for System76's COSMIC alpha - and I have zero regrets

Jack Wallen / Elyse Betters Picaro / ZDNET Follow ZDNET: Add us as a preferred source on Google. ZDNET's key takeaways System76's COSMIC desktop will soon be in beta. Even as an alpha release, COSMIC is impressive. COSMIC is as fast as any Linux desktop I've experienced. Alpha releases aren't to be used for any reason other than testing. Right? That's the common opinion, and yet here I am, working on System76's COSMIC desktop as if it's in stable status. It's not... and it shows. Yes, I

The iPhone 17 camera looks completely outdated next to 2025’s Android phones

Apple has just launched the iPhone 17 series, and there are quite a few camera changes this time. We’ve got a square selfie camera sensor that enables portrait or landscape shots without rotating the phone, a 48MP 4x camera for the Pro phones, and a 48MP ultrawide camera for the standard model. Unfortunately, one thing you won’t find on the standard Phone 17 is a telephoto camera. Apple has decided to skip this option yet again, and this is a frankly embarrassing decision in 2025. What do you

Gasoline vs. Electric Cars: A Plug-In Hybrid Can Give You the Best of Both Worlds

Despite the growing popularity of traditional electric vehicles, not everyone is ready for one. There's another option that's a good first step for many drivers: plug-in hybrids. "A plug-in hybrid is the gateway drug for EVs," says Amelia Dalgaard, an automotive expert known online as the Motorhead Mama. That's because plug-in hybrids address the range anxiety that stops some car buyers from going full-EV at first. Plug-in hybrids let you drive on battery power for a limited distance, with a

It's taken three years to recover from China hack, election watchdog says
