A pair of once-in-a-lifetime comets will rocket through our skies this October. It’s a rare treat for skywatchers, as they won’t be back again for hundreds of years. 

The comets — C/2025 A6 (Lemmon) and C/2025 R2 (SWAN) — look similar from our perspective. You can spot these green gaseous globes and their streaming tails now. But the comets will be even easier to see later this month.

SWAN will shine the brightest around Oct. 20, NBC News reports. Just a day later, on Oct. 21, Lemmon will make its peak showing in the dark sky.

If you want to witness these comets shooting past Earth, the coming weeks will be the best time. There won’t be another chance; the next time SWAN will come by again will be in 650 to 700 years, and Lemmon won’t return for another 1,300 years, CNN reports. 

Comets are known to buck even the most careful predictions, but wary observers might catch these rare spectacles in October from their backyards in the pre-dawn morning or night sky. 

New comets on the scene

Lemmon and SWAN were both discovered in 2025. Lemmon was discovered on Jan. 3 in Arizona by the Mount Lemmon Survey — using a 60-inch telescope installed on Mt. Lemmon to find celestial objects — which lent the comet its name. 

«Current models are showing the comet will likely peak between 3.5 and 4.5 magnitudes when it is nearest to Earth on October 21, which is dimmer than what they showed last week,» Saint Louis Science Center wrote in an October update. «This is still bright enough that it could become naked-eye visible from light-polluted locations.»

A Ukrainian amateur astronomer named Vladimir Bezugly discovered the SWAN comet on Sept. 11 while he was looking through images captured by SWAN, a science instrument called Solar Wind ANisotropies, which is installed on the Solar and Heliospheric Observatory in space. 

«It was an easy comet for detection due to sufficient brightness in the (ultraviolet) band and location in the SWAN images, exactly in its center,» Bezugly told Universe Today. He also noted it’s the 20th official SWAN comet so far.

How to see Lemmon and SWAN this October

The darker the night sky, the easier it will be to see comets, moons, planets and stars. If you live in a city, bundle up and take an evening skygazing trip to the country where there’s less light pollution, with blankets, chairs and something warm to drink.

It takes a while for your eyes to adjust to the darkness. Find a comfortable spot where you can stay still and gaze up. The comets might be bright enough to see without aid, but NASA recommends binoculars as a great entry-level stargazing tool.

Telescopes are one of the best ways to skygaze, and you might be able to find one to use or rent at your local library or university. But modern telescopes can also be fairly affordable. 

Smartphone apps can also be helpful when trying to identify celestial phenomena and where to find them. Check out our list of stargazing apps for a few recommendations. 

A sky full of wonders

Aside from the newly discovered comets, skywatchers have a few other cosmic treats to enjoy this month. 

The Orionids meteor shower — when Earth travels through the massive tail of Halley’s Comet — began earlier this month, but you’ll be able to see the meteors through the beginning of November. 

The next supermoon, known as the beaver moon, will take place on Nov. 5. 

I’d love to tell you all about Pokemon Legends: Z-A, arriving this week, and what it’s been like to play on the Nintendo Switch 2. I can mostly do that — but for most of the past five days, it hasn’t really been me playing. What started as co-playing together quickly turned into my kid taking over completely as he got hooked. And honestly, I’d say that’s a good sign.

Nintendo makes a lot of Pokemon games, too many for me to keep track of. But Legends Z-A is the first that’s Switch 2-optimized, although you can play on original Switches, too. I can’t tell you what that’s like, though — my early review access limited me to playing Pokemon Legends: Z-A on the Switch 2 only at home. I was doubtful about how much a city-based game would truly feel like a must-have experience, but so far it’s already become one of my favorite Pokemon games ever. 

I’ll let my son tell you. He’s gotten deep into the trading card game and has played most of the recent Pokemon titles over the past year, and he says this is his favorite so far. When I asked him why, he said it’s because the game completely rethinks how battles work. The quick, real-time system feels more immediate and far less sluggish than in past Pokemon games. Plus, he’s loving the story… and honestly, so am I.

A city full of surprises

My son loves the «peculiar» storyline, the fast-paced battles (which he now wants in every Pokemon game) and the constant sense of surprise while exploring Lumiose City.

All of Pokemon Legends: Z-A (at least from what I’ve seen in my 10-plus hours so far) takes place entirely within Lumiose City — a Paris-like metropolis where the CEO of a company called Quasartico Inc. is planning to rebuild everything into a new world where Pokemon and humans can better coexist. The setup reminded me of the Detective Pikachu movie during my demo a few weeks ago, and it turns out my instincts were right.

Pokemon roam in wild zones within the city, occasionally spilling into urban areas, while mysterious rogue «Mega Evolution» Pokemon have begun appearing and threatening the city’s calm. There’s clearly a deeper mystery at play, and while I’m still uncovering it, I won’t spoil anything here.

The game seems to mostly involve a journey to level up in rank from Z to A by battling various Pokemon trainers, but that’s not the whole story. There’s a group of friends you hang out with at a local hotel, along with research missions you have to carry out. Side quests are everywhere. The city, though it can feel a bit sparse at times, stretches all the way up to its rooftops, where all sorts of hidden spots are waiting to be discovered. It feels like a living maze, and one I’m still navigating.

And the city’s always changing, too. Wild zones keep multiplying, and from day to night the city’s dynamics shift. Battles take place at night, with trainers gathering in new pop-up spots each time. It’s not as lively as I’d hoped — this isn’t Grand Theft Pokemon — but the cozy, vibrant world still makes me daydream about what a real-life Universal Pokemon theme park could someday look like.

The Pokemon shine

I keep reminding myself to take extra time to discover and level up my Pokemon. At least that’s what my son’s telling me to do. He loves how many Pokemon can become Mega Evolved in this game, and how much fun the battle moves are to pull off. I’m happy he’s happy. I thought I’d get lost in the RPG aspects of the game, but I think the real-time Pokemon battles put me in a looser state of mind, more able to explore and not feel locked down into systems and rulesets. Swapping Pokemon battle moves and reassigning them to buttons is easy, too.

The stronger focus on trainer battles — and the sheer variety of Pokemon capable of mega evolving — gives the game more of that classic, Pokemon-centered energy than Pokemon Legends: Arceus ever did. I found myself more excited to see how different Pokemon looked and behaved than to uncover new realms to explore. After all, for all of Lumiose City’s secrets, you’re spending a lot more time roaming one massive location than in any other Pokemon game I can remember. Thankfully, the visual upgrades on the Switch 2 make those Pokemon look fantastic in battle.

I do want to spend more time in Lumiose City, though, and can’t help but wonder if this is a glimpse of how all Pokemon games will keep evolving. It’s hard to say, since Legends games like Z-A and Arceus have been more experimental than the rest of the series. But, like Arceus, Z-A is now one of my favorite Pokemon games on Switch. And on Switch 2, it plays smoother and feels better than any Pokemon game ever has before.

Despite tariffs and market uncertainty, global smartphone shipments increased 2.6% in the third quarter of 2025, compared to the same time last year, according to the International Data Corporation. Additionally, preorders for the iPhone 17, which launched last month, outpaced last year’s iPhone 16.

These increased sales include premium phones like the latest iPhones and Samsung foldables, suggesting yet again that pricier phones still sell in periods of economic strain. It’s a remarkable achievement, says IDC senior research director Nabila Popal, citing shrewd financing options as the reason people keep buying these high-end phones, which cost anywhere from $800 to nearly $2,000.

«[Phone makers] have mastered the art of innovation not only in hardware and software to entice upgrades but also in removing purchase friction. They have flawlessly combined cutting-edge devices with innovative financing models and aggressive trade-in programs that make the upgrading decision a ‘no-brainer’ for consumers,» Popal said in an IDC press release.

Apple sold 58.6 million iPhones this quarter, an increase of 2.9% over the same period in 2024, with more preorders for the iPhone 17 series than its predecessor. But Samsung wasn’t far behind, with its Galaxy Z Fold 7 and Galaxy Z Flip 7 selling better than all of the company’s prior foldables. The company still reigns atop the phone market with 61.4 million phones sold, representing 19% of the market in the third quarter of this year — an increase of 6.3% from the same period last year. Meanwhile, Apple lands slightly behind Samsung with 18.2% market share this quarter. 

The other phone makers trailing Apple and Samsung are, in order: Xiaomi, with 13.5% of the market; Transsion, with 9%; and Vivo with 8.9%. The remaining companies in the phones industry, from Chinese stalwarts like Oppo and Honor to Motorola and Google, make up the remaining 31.4% of the market for the quarter. All told, 322.7 million phones were sold, up from 314.6 million in the third quarter of 2024, according to IDC.

IDC’s findings for the third quarter continue the small but steady growth of phone sales over the year, including a modest 1% increase in the preceding three months — which includes the April deadline when President Donald Trump unveiled sweeping tariffs. In the second quarter, IDC cited midrange devices like Samsung’s Galaxy A36 and other phones that started incorporating AI. But even persistent tariffs haven’t slowed down people’s appetites for pricier phones in the third quarter.
