If you want to see two comets, your best chance will be early this week. After a year without any comets bright enough to be seen without specialist equipment, two — Comet C/2025 A6 (Lemmon) and Comet C/2025 R2 (SWAN) — have come along at once.Comet Lemmon may look more like a lime than its name suggests, but on Tuesday (Oct. 21), the dusty snowball from the outer solar system will reach its closest point to Earth and most likely shine at its brightest. It’s now reached magnitude 4.5, according to SpaceWeather.com — about the same brightness as spring’s Beehive…
Top 4 360 Cameras ComparedOther OptionsPhotograph: Scott GilbertsonInsta360 X3 for $300: You’ll have to settle for 5.7K footage here, and that’s on a 1/2-inch sensor, which is only 1080p when you crop to a rectangular video format. Still, you get nearly the same form factor as the X4, and you can use it as a 4K, single-lens action cam. At this price the X3 remains a viable option for those wanting to dabble in 360 video without spending a fortune.Insta360 One RS for $300: The company’s interchangeable-lens action-camera/360-camera hybrid is another option. The video footage isn’t as good as the…
QUICK FACTSName: Chestnut Ridge Falls, or “Eternal Flame Falls”Location: Chestnut Ridge Park, Erie County, New YorkCoordinates: 42.70158, -78.75113Why it’s incredible: The falls house a natural gas seep that can burn uninterrupted.Eternal Flame Falls is a waterfall in New York State that houses one of the world’s few natural “eternal” flames.The waterfall is about 30 feet (9 meters) tall and consists of two tiers; one at the top measuring 8 feet (2.5 m) high and the other at the base making up the remaining height. The cascade flows over an outcrop of shale, a type of sedimentary rock made of compacted…
Compare Top 7 Best WebcamsBefore You Buy, Try Using Your SmartphoneAccordionItemContainerButtonYou may not need a dedicated webcam at all. It’s actually really easy to use your smartphone’s cameras as a webcam instead, and they’re usually far superior. Recent iPhones, for example, have a feature called Continuity Camera—this works with certain MacBooks and allows you to wirelessly use the iPhone’s camera as a webcam. Apple even sells a Belkin mount that lets you hang your iPhone off the top of your MacBook or external monitor for the full effect.Photograph: Julian ChokkattuBelkiniPhone Mount With MagSafe for MacBooksGoogle Pixel phones also now feature…
Looking for an ultra-advanced adventure smartwatch, but do not want to spend a small fortune on the Garmin Fenix 8? Consider the Garmin Enduro 2 instead. It is just as durable, advanced and rich in features as its more widely known counterpart. The Enduro 2 used to be just as expensive, too, but since it has been discontinued to make space for the newer Enduro 3, its price has been steadily dropping over the last few months. Now, this ultra-premium watch is the cheapest it has ever been.The Garmin Enduro 2 has just been discounted by $81.95 at Walmart, bringing…
While open-source crusaders and techno-libertarians are applauding Universal Audio’s recent efforts to move away from its “walled garden” approach to plug-ins, the truth is that most of the good ones still require the presence of an interface or a processor core to load up and run in your DAW of choice. As we mentioned in the write-up of the Apollo Twin, above: “good” is a massive understatement when describing UAD’s most popular plug-ins.Its digital re-creations of optical mix bus compressors, legendary reverbs, and warm, vibey tape machines are unmatched by any other prosumer-level manufacturer, and the fact that its hardware…
In a universe where change usually unfolds over eons, astronomers have gotten a rare front-row seat to watch a small, icy world beyond Saturn build a brand-new set of rings in real time.A team of Brazil-based astronomers found that the bands of material orbiting around (2060) Chiron, a 125-mile-wide (200 kilometers wide) object that circles the sun between Saturn and Uranus, are new and still taking shape. The findings suggest that Chiron’s surroundings are in a transitional state somewhere between a chaotic cloud of debris and a fully formed ring system, offering scientists a rare snapshot of ring formation in…
Both also serve as reminders to current team members of what’s possible if they continue pursuing STEM fields. Ismail is in his third year studying computer engineering at Queen’s, while Shanti is a freshman studying business intelligence (a combination of business and tech applications) at Al-Najah National University in the West Bank.Dalia Nasr, 2025 Team Palestine student: The alumni, I can learn from them. There are not a lot of robotics courses in Palestine. It’s not really common for us to have these kinds of things. So it’s a really, really big opportunity for me.Ismail: At some point, I was…
Researchers have developed a lightweight computer mouse that you wear on your finger like a ring and works for more than a month on a single charge.Called picoRing, the device weighs just 0.18 ounces (5 grams) and is designed as a discreet, low-power alternative to traditional mice.Its inventors see it initially as a contender for controlling augmented reality (AR) and virtual reality (VR) systems, where compact, hands-free control offers a practical advantage over standard input devices. Users can scroll and interact with virtual interfaces using small hand gestures, making picoRing ideal for setups that lack desk space.Because the ring sits…
European roboticists today released a powerful open-source artificial intelligence model that acts as a brain for industrial robots—helping them grasp and manipulate things with new dexterity.The new model, SPEAR-1, was developed by researchers at the Institute for Computer Science, Artificial Intelligence and Technology (INSAIT) in Bulgaria. It may help other researchers and startups build and experiment with smarter hardware for factories and warehouses.Just as open source language models have made it possible for researchers and companies to experiment with generative AI, Martin Vechev, a computer scientist at INSIAT and ETH Zurich, says SPEAR-1 should help roboticists to experiment and iterate…
