Webb telescope images an aging binary star system in the center of a four-layered cosmic dust shell

Posted on by

NASA’s James Webb Space Telescope has shown us images of space we’d never see otherwise, and one of the latest wonders it has captured is of an unusual star system in our galaxy with what the agency describes as “four serpentine spirals of dust.” Previous observations of the Apep system, named after the Egyptian god of chaos and located around 8,000 light-years away from Eath, showed only one shell. But as you can see in the mid-infrared image captured by Webb above, it actually has four shells, with the most outer one at the very edges of the image. These shells are made out of dense carbon dust emitted by the system’s two Wolf-Rayet stars over the last 700 years.

Wolf-Rayets are massive stars nearing the end of their lives. They’re very rare, and scientists believe there are only a thousand in our galaxy. Apep happens to have two of them. Yinuo Han from Caltech and Ryan White from the Macquarie University in Sydney, Australia have recently published their own papers about the system. They combined measurements from Webb’s observations with years of data from the European Southern Observatory’s Very Large Telescope (VLT) in Chile to determine that the two stars “swing by one another” once very 190 years. The stars then pass close to each other for 25 years, causing their strong stellar winds to collide and cast out huge amounts of carbon-rich dust within that timeframe.

Thanks to the Webb telescope’s observations, they were also able to confirm the presence of a third star in the system that’s gravitationally bound to the two Wolf-Rayets. The third star is a massive supergiant 40 to 50 times bigger than our sun, and it carved a cavity, which looks like a funnel, into the shells. You can see the cavity in the shells in the video below.

Apep’s Wolf-Rayet stars used to be bigger than the supergiant, but they’ve since shed most of their masses and are now only 10 to 20 times the mass of our sun. In time, the two stars will explode into a supernova and possibly turn into a black hole.

Spotify’s SongDNA feature will show you which songs are sampled on a track

Posted on by

Spotify has unveiled an upcoming interactive feature called SongDNA designed to show you the samples, collaborators and covers included in a given track, the company announced. As part of that update, Spotify also revealed that it has acquired WhoSampled, the company behind the SongDNA technology.

"Through our recent discussions with Spotify, it became clear that we share a strong belief in the power of musical context — and a vision for helping listeners go deeper into the songs they love," the WhoSampled team wrote in a blog post. 

Terms of the deal weren't disclosed, but Spotify is acquiring both the WhoSampled team and its database. WhoSampled's standalone platform and brand will continue to operate following the deal with improvements like faster moderation times, the elimination of display ads and free downloads and subscriptions for its mobile apps.

Spotify Premium users will see the SongDNA feature in the "Now Playing" view. It's described as a way to see connections between songs, "showing collaborators, samples and covers all in one place," Spotify wrote. 

In the song Kiss me More (feat. SZA), for example, SongDNA shows Carter Lang and two other composers, along with Doja Cat and SZA as the main artists. It reveals that a sample is used from Olivia Newton-John's Physical and that Kiss me More has been covered multiple times, most prominently in a Japanese version by the artist Rainych.   

Spotify is also working on a feature called "About the song," showing swipeable cards in the "Now Playing" view. Those will reveal information like the inspiration for a song, how the music was created and the cultural impact — all with links to the sources.

London-based WhoSampled tracks over 1.2 million songs and 622,000 samples in its database, along with covers, remixes and artists. Its mobile app offers a Shazam-style music recognition service that can tell you the song you're listening to and any samples it might contain. The two companies have partnered previously on a deal that allows WhoSampled users to access their Spotify playlists and tracks.

Apple Black Friday deals: Pick up the iPad A16 for its lowest price yet

Posted on by

The iPad A16 is now on sale for $274 for Black Friday, giving you a chance to pick up Apple’s newest entry-level tablet at a discount. It’s the most affordable iPad in the current lineup, offering quick performance, strong battery life and all the essentials for everyday use.

Apple’s latest 11-inch iPad uses the A16 chip, the same processor found in the iPhone 15, delivering fast and reliable performance for most tasks. Whether you’re watching videos, editing documents or using creative apps, it feels responsive and capable. The A16 chip also helps future-proof the device, ensuring it stays compatible with new iPadOS updates for years.

The tablet’s 11-inch Liquid Retina display (2360 x 1640) offers sharp detail and vivid color at up to 500 nits of brightness. While it doesn’t have the ultra-bright XDR panel of the iPad Pro, it’s more than crisp enough for streaming or sketching with the Apple Pencil. The design follows Apple’s familiar flat-edge style, with slim bezels and an aluminum build that keeps it light and durable.

The iPad includes a 12MP rear camera and a 12MP front-facing Center Stage camera, which automatically adjusts to keep you in frame during video calls. The front camera is positioned along the longer landscape edge, which gives a more natural angle for calls or recordings. You also get Wi-Fi 6, Bluetooth 5.3, USB-C for charging and data transfer, plus Touch ID built into the top button. Battery life runs up to 10 hours on Wi-Fi, which is consistent with Apple’s other models.

Accessory support covers the Apple Pencil (USB-C) and the first-generation Apple Pencil with the USB-C adapter, along with the Magic Keyboard Folio. It doesn’t work with the Apple Pencil Pro, but for casual drawing, note-taking or quick document markup, these accessories add plenty of flexibility.

The A16 iPad sits at the entry point of Apple’s lineup, but it shares a lot of what makes its pricier siblings appealing. You get a polished display, dependable performance and the familiarity of iPadOS without the premium cost. It’s an ideal choice for students, casual users or anyone who wants a reliable tablet for daily use.

If you’re still deciding which model fits you best, check out our guide to the best iPads to compare the A16 against the Air and Pro models. At $274, this iPad deal offers excellent value for Apple’s newest entry-level tablet. Also on sale for Black Friday is the 11-inch iPad Air M3, which is down to $449.

AirPods Pro 3 are $30 off and down to a record low for Black Friday

Posted on by

Apple’s new AirPods Pro 3 are already shaping up to be one of the most sought-after tech gifts this season, and now you can grab them at a lower price. They’re on sale for $220, down from the regular $249. Previously, the lowest we’ve seen the AirPods Pro 3 discounted to is $239. If you’ve been holding off on upgrading your earbuds, this is the deal worth grabbing.

Apple didn’t reinvent its flagship earbuds with the AirPods Pro 3, but it made smart refinements that elevate nearly every part of the listening experience. We praised these earbuds in our AirPods Pro 3 review for delivering noticeably richer audio and more effective active noise cancellation while keeping the same pocketable form factor that made earlier models so popular.

The standout upgrade here is Apple’s Live Translation feature, which was an unexpected but welcome surprise, announced at the iPhone 17 event. Leveraging Apple’s H2 chip, the AirPods Pro 3 combines Voice Isolation, ANC and beamforming mics to kick Live Translation into action. Siri’s translation filters seamlessly through the earbuds, but if environmental noise gets too intrusive, you can view a real-time transcription in the iOS Translate app, which is a useful feature for international travel and business calls.

Battery life has improved, too. You get up to eight hours on a single charge with ANC on, and the case adds another 24 hours of playback. The MagSafe charging case, with its new U2 chip, now supports an increased distance for Precision Find My, so it’s easier to locate if misplaced.

Since we’re talking about earbuds, audio quality plays a key role in deciding whether to purchase the AirPods Pro 3 or upgrade from a previous model. Although improvements have been made to sound quality through new drivers and transducers, Apple’s decision to increase air flow inside the earbuds has been the most noticeable update. You can expect the AirPods Pro 3 to deliver deeper bass, crisper highs, and an expanded soundstage that makes everything from podcasts to orchestral tracks feel more dynamic.

There’s not much to fault here beyond the familiar Apple premium price, but that’s why this AirPods Pro 3 deal is such good news. The AirPods Pro 3 remain the best wireless earbuds for iPhone users who want seamless connectivity, top-tier ANC and reliable comfort. But if you were hoping to spend a little less, the AirPods 4 with ANC are on sale for $139 right now as well, and the standard AirPods 4 are down to $69. If you prefer over-ear headphones, select colors of the AirPods Max are down to $400.

Sonos Black Friday deals: Get the Era 300 speaker on sale for $100 off

Posted on by

Black Friday is as good a time as any to upgrade your home audio setup. You can get the Sonos Era 300, the company's only standalone speaker with spatial audio, for $379. That's $100 off what Engadget's Nathan Ingraham called "a great speaker, whether or not it is playing songs in Dolby Atmos."

That Dolby reference points to the Era 300's core novelty. It produces spatial audio without requiring additional speakers. (You can use Apple Music or Amazon Music to stream compatible tracks.) Expect those Dolby Atmos tracks to sound better with newer music than older songs remixed for Dolby's tech.

Even if you don't bother with its spatial tricks, the Era 300 is a terrific-sounding speaker. It delivers rich, detailed and balanced audio that can hang with just about anything else Sonos offers.

The speaker supports voice control via Alexa or Sonos Voice Control. It also offers Trueplay tuning, which listens to how your room shapes the sound and adjusts accordingly. In this model, you don't need to use your phone: Its built-in mics scan your room for you. That's especially handy for Android users, since phone-based Trueplay (from other models) is iOS-only.

If the Era 300 is a bit out of your budget, Sonos has loads of other products on sale for Black Friday. You can get the smaller — but still mighty — Era 100 for $169 (23 percent off). The portable Move 2 is down to $399 (20 percent off). Even the company's headphones, Sonos Ace, are on sale for $279 (30 percent off).

Sonos home theater products are discounted, too. You can get the Arc Ultra soundbar for $879 (20 percent off), or the Sub 4 subwoofer for $719 (also 20 percent off). Or, if you're in the market for both and have the budget, save even more on a bundle: Get the Arc Ultra and Sub 4 for $1,499 (25 percent off).

Get $50 off the Xreal One Pro smart glasses for Black Friday

Posted on by

Some Xreal smart glasses have been discounted as part of a Black Friday promotion. This includes the recently-released Xreal One Pro glasses. The smart specs are down to $599, which is $50 off. The sale applies to both sizes.

These glasses are the real deal. We praised them in our official review, saying they offer similar functionality to the Apple Vision Pro, but at a much friendlier price point. Wearing these glasses allows access to a massive 222-inch virtual display that can be used for just about anything. The glasses connect to laptops, gaming consoles and smartphones, among other gadgets.

The 1080p Micro-OLED screens are surprisingly bright and sharp, which makes this device great for both work and consuming content. The frames even darken to give the illusion of wearing sunglasses.

The glasses are light and comfortable, especially when compared to the Vision Pro. However, the comfort does come at a price. These oversized glasses are not as immersive as Apple's product, because they don't completely block out light and cover the entire face. They offer a 57-degree field of view. This is squarely an augmented reality product and not a virtual reality product.

The company has also discounted its Xreal One AR glasses to $399, which is a discount of around $100. These offer smaller virtual screens than the Pro, with a 50-degree field of view. Elsewhere in the smart glasses space, the Meta Ray Ban Gen 1 glasses are 20 percent off for Black Friday as well.

Amazon’s Kindle Colorsoft is 32 percent off in this Black Friday deal

Posted on by

Amazon is hosting a Black Friday sale that covers many of its ereaders. This includes the Kindle Colorsoft, which has been discounted to $170. This thing usually costs $250, so this is one heck of a deal and a record low price.

The model came out earlier this year and we gave it a glowing review, calling it "the missing link in Amazon's ereader lineup." It's the first Kindle ereader in color, which makes this thing one of the best ways to read comic books and graphic novels. The pinch-to-zoom feature lets you get closer to details, to make each panel really pop.

This is also a high-end ereader, color or not. We found the load times to be exceptionally fast and the same goes for turning pages. There's an auto-adjusting front light, which comes in handy. There are also no lock screen ads by default and a single charge lasts eight full weeks of regular use.

The major downside here is the price. It's tough to truly recommend any ereader at $250, or the original launch price of $280. It's a lot easier to recommend at $170.

Amazon is also selling similar products at a discount, some of which made our list of the best ereaders. The base Kindle is down to $80, which is another record low. The Paperwhite is on sale for $125, yet another record low price. And keeping with the theme, the current-gen Kindle Scribe is on sale for as low as $280, the cheapest we've seen it.

Get the Roku Streaming Stick Plus for only $19 this Black Friday

Posted on by

For anyone looking to get a great deal on a streaming device, Roku's Black Friday deals are here. The Roku Streaming Stick Plus, which just happens to be one of our favorite streaming devices, is 50 percent off, on sale for just $19. The regular Streaming Stick and Streaming Stick 4K are also on sale for 47 percent and 50 percent off, coming in at $15 and $25 respectively.

Roku makes some of the best streaming devices you can get, and any of the ones on sale would be great picks to upgrade an old TV you already have. The Streaming Stick Plus is our favorite of the bunch since it supports 4K HDR content and gives you access to a bunch of free content thanks to Roku's streaming OS. We also appreciate its accurate universal search and the fact that it draws power from your TV, so it doesn't need to be plugged into a wall outlet to get power.

The standard Streaming Stick is a good alternative to Amazon's most basic Fire TV Stick, and if you already prefer Roku's streaming OS, it's arguably the better choice. The Streaming Stick 4K adds Dolby Vision into the mix, if that's a must-have for you. Also, if you're looking for a more powerful set-top streaming box, the Roku Ultra is 30 percent off, marked down to $69 from $100.

The best robot vacuum for 2026

Posted on by

Looking to keep your home clean without having to vacuum and mop every day, pick up dirt, the dinner your child threw on the floor or your furry friend’s endless pet hair? Join the club. Smart home gadgets have come a long way over the years, and that includes robot vacuums. With newer technology including voice controls, object detection and more automation features, investing in a robot vacuum cleaner makes more sense now than ever before. Some of the best robot vacuum cleaners even have mopping capabilities, roller brush options and self-emptying bases, too, and there are plenty that don't cost a fortune either. If you’re ready to adopt a less hands-on approach and let a robot vacuum cleaner do the hard work for you, consider our recommendations below.

CES is typically a time for robovac manufacturers to unveil new innovations and this year was no different. Companies like Eufy announced new models, many of which are on the higher end of the price spectrum. Those flagship announcements are often paired with more minor ones that usher in mildly upgraded versions of midrange and entry-level machines.

Now that robot vacuums are ubiquitous, the new models that make headlines tend to have some sort of gimmick like a built-in arm for picking up clothes, or offer (supposedly) top-tier suction power and a slew of extras. They also tend to be super expensive. However, most people will be served just fine with a robot vacuum that doesn’t choke at the first sign of dust bunnies or pet hair, and maybe has mopping capabilities if you want a machine that can tackle hard floors in addition to carpet. Those other innovations are nice-to-haves, not necessities.

Arguably even bigger than CES announcements is the fact that iRobot, a name synonymous with smart cleaning robots, filed for Chapter 11 bankruptcy at the end of 2025. What does that mean for Roomba owners? Not too much immediately, as the company stated that it will continue to operate with “no anticipated disruption to its app functionality, customer programs, global partners, supply chain relationships or ongoing product support." However, this also means that buying a new Roomba in 2026 is a questionable decision.

Despite companies coming out with gimmicky extras and new software perks in their robot vacuum lineups, the core competency of these devices have remained the same for years: sucking up dirt without needing your attention. You want a robot vacuum with the strongest suction power you can afford. Those with tile and hardwood floors can consider robovacs with mopping capabilities, and those who want peak convenience should opt for a model with a self-emptying base. However, both of those extra features will cost extra.

First and foremost, we recommend considering the floors in your home: Do you have carpet throughout, or tile and hardwood floors, or a mix? Robots with stronger suction power will do a better job picking up dirt on carpets as they can get into high piles more easily. Some machines have “max” modes as well, which ups suction power, but also typically eats battery life faster than the “normal” floor cleaning mode.

Suction power is an important factor to consider. Unfortunately, there isn’t a standard power scale that all robovacs adhere to, so it’s difficult to compare among a bunch of devices. Some companies provide Pascal (Pa) levels and generally the higher the Pa, the stronger the vacuum cleaner will be. But other companies don’t rely on Pa and simply say their robots have X-times more suction than other robots. If you’re looking for the best vacuum for your needs, it’s helpful to pay attention to real-world testing and how well the machine can pick up fine dust, crumbs and pet hair in an environment similar to that of your home.

Wi-Fi connectivity is a key feature for most robot vacuums. Some of the affordable devices aren’t Wi-Fi connected, so it’s best to double check before you buy something on the low end of affordable. Wi-Fi lets a robot vacuum cleaner do things like communicate with a mobile app, which then allows you to control the device from your phone.

Past a certain price threshold, you’ll find advanced perks like home mapping features and improved object detection. Home mapping is exactly what it sounds like: The vacuum uses sensors to map your home’s layout as it cleans, allowing you to send it to particular rooms or avoid no-go zones where you don’t want it to roam.

Most robo-vacs have object detection, but some will be better than others at actually avoiding things like chair legs and children’s toys. High-end models even go so far as to promise obstacle avoidance to steer clear of things like pet poop that can potentially ruin your machine.

Mopping features are much more common now in robot vacuums than they were just five years ago. Machines that support this will have a water tank either built into the robot’s chassis, the auto-empty bin or as a separate piece that you swap in for the dustbin when you want to mop your floors. It makes the robo-vac more useful if you have hard floors in your home that you like to keep squeaky clean, but it does require more work on your part.

Filling and emptying the reservoir remains a human’s job for the most part (except on the most expensive machines), as does adding cleaning solutions if the mopping robot comes with this feature to ensure it uses clean water for every cycle.

Finally, for peak convenience, consider a robot vacuum that comes with a self-empty station. These are basically garbage bins attached to the machine’s docking station. At the end of each job, the robo-vac automatically empties its small dustbin into the large clean base – that means you won’t have to empty the dustbin yourself and you’ll only have to tend to the base once every few weeks.

Just keep in mind that many self-emptying bins require proprietary garbage bags – another long-term expense you’ll have to factor in (look for mentions of “bagless” to avoid this all together). Also, any vac-and-mop robot with a water tank will not dump its dirty water into the clean base, so you’ll still have to clean up that yourself.

First and foremost, always empty your robot vacuum’s dustbin after every cleaning job. If you have a model with a self-emptying base, there’s less work for you to do yourself. If not, simply detach and empty the dustbin as soon as the robot is done cleaning. It’s also a good idea to take a dry cloth to the inside of the dustbin every once in a while to remove any small dust and dirt particles clinging to the insides.

In addition, you’ll want to regularly examine the machine’s brush roll to see if any hair has wrapped around them, or if any large debris is preventing them from working properly. Some brushes are better than others at not succumbing to tangled hair, but it’s a good idea to check your robot’s brushes regardless — both their main brush and any smaller roller brushes or corner brushes they have. These parts are often easy to pop off of the machine (because they do require replacements eventually) so we recommend removing each brush entirely, getting rid of any tangled hair or other debris attached to them and reinstalling them afterwards.

Robot vacuums also have filters that need replacing every couple of months. Check your machine’s user manual or the manufacturer’s website to see how long they recommend going in between filter replacements. Most of the time, these filters cannot be washed, so you will need to buy new ones either directly from the manufacturer or from other retailers like Amazon or Walmart.

We primarily test robot vacuums by using them as they are intended to be used: in a home, across different types of flooring and in the face of all sorts of messes including pet hair, spilt coffee grounds and other food debris, dust bunnies, stairs (gasp) and more. We set up all robot vacuums according to their provided instructions and run multiple cleaning jobs during a testing period of at least one to two weeks per machine.

If the robot has mopping capabilities, we also test those as well on hardwood and tile flooring. For models with self-emptying bases, we rely on those built-in trash cans for all post-job cleaning, and we make sure to test the robot vacuum's mobile app for usability and convenience. As we're testing, we make note of things like how loud the robot and its components are, how much human attention the robot needs on a regular basis, how the robot handles large messes and big dust bunnies, if the robot gets stuck on rugs, doormats or other furniture and more.

We tackled this question when we reviewed budget robot vacuums and the answer is yes, especially if vacuuming is one of your least favorite chores. Robots take the hard work out of cleaning your floors – just turn the thing on and watch it go. Any robot vacuum cleaner worth buying is semi-autonomous in that it will suck up dirt around your home until its battery is low and then make its way back to its charging dock. Unlike a regular vacuum, you should only have to interact with it to turn it on, empty its dustbin and untangle it if it were to get stuck somewhere.

That’s not to say robot vacuums are perfect. They’re almost always less powerful and less flexible than traditional vacuums. Since most robo-vacs are much smaller than traditional models, they often don’t have the same level of suction you’ll get in an upright machine. Plus, their dustbins are smaller, so they will need to be emptied more frequently. While Wi-Fi-connected robot vacuums give you the flexibility to start a cleaning job from anywhere using an app, targeting a small area of your home can be more complicated. Some robo-vacs have spot-cleaning features that focus the machine’s attention on a specific area, which almost – but not quite – mimics the spot-cleaning you’d be able to do yourself with a regular or cordless vacuum.

Robot vacuums can last many years, if you take care of them properly. Check out our recommendations for robot vacuum maintenance above, but in a nutshell, you should make sure that you're emptying the machine's bin after every job and periodically cleaning the interior of the bin and the brushes. It's also a good idea to check the user manual to see how often your robot vacuum's filter needs changing.

There's no straight answer to this question. Robot vacuums offer more convenience than handheld vacuums, so for those who are looking to automate a chore, that could mean one of these devices works better for them than a standard vacuum. However, handheld vacuum cleaners often have stronger suction power, and they give the user a bit more control. It ultimately depends on how you intend to use your main vacuum cleaner and what you want to prioritize most.

Cleaning a robot vacuum isn’t too much of a chore, but you’ll want to give it a little TLC every few weeks or so, depending on how often you’re running it and how much dirt it’s picking up. The dustbin usually needs to be emptied after each cleaning run, especially if you have pets or lots of carpet where dirt can hide. Many newer models have self-emptying docks, which means you won’t have to empty the dustbin yourself after every use, but the main bin will still need a good clean once a month or so. Also, it’s a good idea to check the side brushes and main brush for any hair tangles or debris every couple of weeks to keep things running smoothly.

Robot vacuums won’t work for everyone. One of the biggest drawbacks is that they usually don’t have the same suction power as a full-sized upright vacuum or even a cordless stick vacuum, so they might struggle with deep-cleaning thick carpets. They’re also designed for floors only, so if you’re looking to clean furniture, stairs or other tricky spots, you’ll still need a traditional vacuum to do that. Plus, they can sometimes get stuck or miss spots, especially if you’ve got a lot of furniture or obstacles in the way. While their sensors help, they might still bump into things or need a little help getting out of tight spots. And while most have decent dirt detection features, they’re best for keeping things tidy rather than doing heavy-duty cleaning.

One of our favorite Shark robot vacuums is 58 percent off right now for Black Friday

Posted on by

Our pick for the best robot vacuum (or at least one of its many variants) is on sale. Amazon's Black Friday deals include the Shark AI Ultra robot vacuum. This model has a list price of $599, but you can snag one for $250. That's 58 percent off — and a record low.

One of this model's standout features is its bagless design. Like many robovacs, it has an auto-empty station. But here, you can remove part of the base, dump its contents in the garbage, and lock it back in place. The base holds up to 60 days of dirt and debris, and you'll never need to order bag refills.

The Shark AI Ultra has strong suction and decent obstacle avoidance (via LiDAR). The robovac cleans in a matrix grid. It auto-maps your home and supports Google Assistant and Alexa for voice control.

The vacuum has a runtime of about 120 minutes. (If it needs to stop and charge, it will auto-resume afterward.) Also note that this is a vacuum-only model: no mopping here.

But Shark has other Black Friday deals if you're interested in a robovac that also mops, or even a cordless stick vacuum instead. The Shark Stratos 2-in-1 robot vacuum and mop is 60 percent off and down to $400 right now, while the Power Detect Pet Plus cordless vacuum with self-emptying base is down to $380.
