Dazzling Comet Nishimura Is Bright Enough to See With the Naked Eye
The space snowball is about to make its closest pass by the Earth as it speeds toward the sun.
The brightest comet of 2023 is making its close pass by our planet over the next couple of days and it is now shining as bright as many stars.
Under dark skies, the comet is easily visible with the naked eye. Unfortunately it’s best viewed from the Northern Hemisphere in the hour before dawn, when the rising sun can make it more challenging to spot.
Comet C/2023 P1 (Nishimura) was first spotted last month by Hideo Nishimura, an amateur astronomer in Japan, using only a digital camera setup and a lot of skill. It’s set to make a close pass by Earth on Sept. 12, and then whip around the sun on Sept. 17 before being flung back out to deep space.
A number of sky watchers and astrophotographers are reporting having luck imaging it using a digital camera on a tripod taking exposures that last at least a few seconds.
Nishimura is expected to grow brighter in the next few days, if it survives that long.
So far the comet has been meeting some serious resistance in the form of blasts of charged particles and plasma issuing forth from a tumultuous sun. Observers like astrophotographer Michael Jaeger (see above) watched Saturday as a solar storm engulfed the comet and appeared to blow a portion of its tail away for a moment.
Here’s a more dramatic example that was captured by NASA in 2007 of Comet Encke having its tail briefly stolen:
«Researchers call this a disconnection event; it’s caused by a CME (or fast solar wind stream) hitting the comet,» former NASA astronomer Tony Phillips wrote at Spaceweather.com. «Nishimura’s tail has since grown back — but it might not last for long. More CMEs are heading its way.»
CME stands for coronal mass ejection, which is an eruption from the outer layers of the sun that often accompanies a solar flare. Think of it as a very strong gust of energetic wind coursing through space and causing electromagnetic chaos. This is the same force that causes auroras to light up the skies when it collides with Earth’s magnetic field. It can also influence other things in space, like asteroids and comets.
The sun is currently building toward the peak of its roughly 11-year solar cycle, which means more frequent flares and CMEs. At least two more of the ejections Phillips mentioned issued forth from the sun’s corona on Tuesday, exploding in the direction of Comet Nishimura.

How to catch the comet
All this rough space weather can be a bit distressing for skywatchers hoping to see the comet with the naked eye. In the Northern Hemisphere it will appear near the horizon, making it a bit tougher to locate.
«It’s really best seen with binoculars or a telescope,» Alison Klesman, who holds a doctoratein astronomy, wrote for Astronomy.com. «But through those optics, it will dazzle.»
You can search for the comet in the constellation Leo an hour or two before sunrise. You can use apps like Stellarium, Star Walk or TheSkyLive to help locate it.

It’s very difficult to know what the future holds for a comet. They can travel for centuries from the edge of the solar system to make a single orbit around the sun. At the same time, they are fragile things with a tendency to disintegrate as they pass through the inner solar system. They’ve even been known to crash into Jupiter or the sun along the way. The dinosaurs may also have had a close encounter with one many millions of years ago.
So with all the turbulence the sun is sending out lately, it’s good to get up early to try to see Nishimura for yourself while it’s still holding itself together. Good luck!

Can Chemicals Turn My Orange iPhone 17 Pink? Here’s What I Found Out
There are reports that some cosmic orange iPhone 17 Pro handsets are turning pink. I threw chemicals at my iPhone to see what would happen.
A recent Reddit thread suggests that it’s possible for a cosmic orange iPhone 17 Pro to turn vibrant pink. As PCMag’s Eric Zeman noted, it’s likely that the phone has been discolored by cleaning substances that affected the finish, turning it from vibrant orange to a wild hot pink. Sure, this might technically be a fault, but in all honesty I love pink phones and the idea of a hot pink iPhone 17 Pro filled me with joy. So I wanted to see if I could test the theory and see just what color-changing effects various household cleaners might have on my phone.
It’s important to note here that the iPhone 17 Pro I used was bought by CNET for the purposes of testing. Had I paid over $1,000 of my own money I wouldn’t be so reckless in smearing it with chemicals that could potentially irreparably harm it. And you shouldn’t either. If you need to clean your phone, do it safely. Disclaimer aside, let’s dive in.
The chemicals
I bought two chemicals to test this out. Zeman explains that it may be oxidation that caused the color to change and that hydrogen peroxide could do this. I couldn’t find this over the counter in the UK, so I instead bought an «oxy-active» stain remover spray that, among other things, contains «oxygen-based bleaching agents» which sounded ideal. Apple also clearly states «don’t use products containing bleach or hydrogen peroxide» on its support page so, naturally, I bought some thick bleach too.
Oxy application
I started by spraying the oxy cleaner on a microfiber cloth until it was noticeably wet from the liquid and then liberally applied this all over the rear of the iPhone. The Reddit user with the affected phone showed that it only affected the metal parts, not the glass back panel, so I made sure to focus my attention on the sides and camera bar.
With the phone well and truly doused in chemicals that have no business being anywhere near a phone, I left it to sit and think about what it had done for 30 minutes — after which time I wiped it dry and took a close inspection. Disappointingly, my phone was still factory orange, rather than «what the hell have you done to your phone» pink. Time to move on.
Bleach blast
I opened the bleach and trying hard not to think about my days as a middle school cleaner, applied a liberal blob of the stuff to a cloth and smeared it over the defenceless phone, concentrating again on the metal areas. I definitely should have worn protective gloves for all of this so please make sure you take better care of yourself than I do if you do anything with bleach.
Again, I gave it a 30-minute settling in period before cleaning it off and inspecting the results.
The phone remained as orange as ever, looking as box fresh as it was the day before when it was, indeed, box fresh. The orange color hadn’t changed and now almost 24 hours later there’s still no sign of discoloration of any kind.
Is the pink iPhone 17 real?
I can’t say with any certainty whether the Reddit user’s images of a pink iPhone 17 Pro are real or not. The cuddly human side of me wants to take them at their word, while the journalist in me is sceptical. What I can say with certainty is that putting your orange iPhone into close contact with household cleaning products isn’t going to win you a funky, ultra-rare pink hue that you could sell on eBay for a small fortune.
It’s possible that using pure peroxide could be the thing that does it, but to be honest, if you’re going out of your way to throw industrial-grade chemicals at your phone then you may as well just directly try and dye it. My goal here was to see how susceptible the orange model is to everyday household cleaners such as kitchen cleaner or bathroom bleach — the sort of things it might naturally come into contact with in routine use. And what I’ve found is that, no, it won’t ruin the nice orange color. But it’s probably still not good for your phone.

Apple’s AirPods Pro 2 have everything you could want from a pair of wireless earbuds, plus a steep discount.
Black Friday deals: The Apple AirPods Pro 2 are some of the best personal audio gear on the market, even if they aren’t the latest model anymore. Sure, Apple’s AirPods Pro 3 are the newest earbuds in the lineup but the AirPods Pro 2 are still an excellent pick for most people.
They’re an even better buy this week during early Black Friday sales when you can get your hands on a pair of Apple AirPods Pro 2 at a discount. Right now, Walmart is shaving a massive $100 off the AirPods Pro 2, dropping the cost to $139. That’s one of the lowest prices we’ve seen — but we doubt this deal will stick around for long.

CNET’s key takeaways
- You can get these amazing earbuds for just $139 right now at Walmart.
- My teenager loves everything about them.
- The sound quality is exceptional.
- The noise cancellation can help give you some peace, even in a busy home.
My 13-year-old daughter loves her music and her privacy, and for years she has wanted a pair of AirPods. They’re not cheap so I’ve only been getting her more budget options, like the Amazon Echo Buds, as a result. These kept seemingly disappearing, though, so I finally ponied up for the AirPods Pro 2.
I picked them up during last year’s sales, and they were definitely well-received. She’s happy, she uses them every day, and she hasn’t lost them yet. The AirPods Pro 2 are currently on sale at Walmart for $139, a nice price for a high-quality pair like these, and one of the lowest we’ve seen.
What about the AirPods Pro 3?
The AirPods Pro 3 weren’t available at the time I bought the AirPods Pro 2, but they were rumored, and I didn’t wait to see what they offered. As CNET’s resident headphone expert, David Carnoy summarized in his AirPods Pro 3 and Pro 3 comparison, the newer model is «significantly improved in the four most important areas: fit, sound quality, noise cancellation and battery life.» They also have heart-rate monitoring, like the Beats Powerbeats Pro 2.

While these are undoubtedly all important things, a lot of people aren’t going to notice the differences or make the most of the new features. With the AirPods Pro 3 being newer, they’re on a smaller sale and are currently available at Amazon for $220, which is $30 off the list price.
Why I didn’t get the AirPods 4 instead
Why did I choose AirPods Pro 2 instead of the AirPods 4 with ANC? First, as I mentioned in another article about a different pair of earbuds I bought, I think sealed, in-ear buds are better than open-design models like the AirPods 4. The seal creates another layer of noise isolation and contributes to superior sound quality, and if you want to pay attention to the world you can always engage ambient sound mode, which Apple calls transparency mode.
Also a factor was that, at the time, Carnoy considered the Pro 2 the best Apple noise-canceling wireless earbuds: «While we’re quite impressed with those new models — and with the AirPods 4 ANC in particular — the AirPods Pro 2 remain arguably the best Apple AirPods you can buy if you don’t mind having silicone ear tips jammed in your ears,» he said.
My daughter uses earplugs all the time to help her sleep, so she definitely qualifies as somebody who’s comfortable stuffing things in her ears. Like her fingers, when I start using words like «sigma,» «skibidi» and «relatable» to try to relate to her.
I asked Carnoy about the Pro 2s potentially not fitting in her kid-size ears and he reassured me that the range of eartips that come with the Pro 2s «now include XS, so they should fit.»
Do AirPods make a great gift?
It took me years to finally understand, but yes, for someone looking for wireless earbuds, AirPods — especially the Apple AirPods Pro 2 — make the perfect gift, regardless of whether you’re a teenage girl.

If You’re Flying for the Holidays, This Bluetooth Dongle Transforms In-Flight Movies, and It’s 35% Off for Black Friday
Watch airplane movies just like you would at home with this game-changing device.
Air travel for the holidays can be stressful, especially when winter weather or flight delays force a change of plans, but one perk of flying still remains — watching new-release movies. However, in-flight entertainment on most airlines usually requires a wired set of earbuds. (And the ones the airline hands out are so bad they may as well not even be connected.)
I’d far prefer to use my wireless, noise-canceling AirPods Pro, but they connect only via Bluetooth. There’s a simple tech solution that makes viewing movies on the plane feel more like watching them on your couch.
The AirFly is a simple Bluetooth dongle that allows me to connect my wireless earbuds directly to the airplane’s entertainment system, eliminating the need for adapters or wired workarounds.
It’s become a must-pack item in my travel bag. Since I started using it, I’ve stopped dreading in-flight audio and finally get to enjoy movies on the plane. If you fly often, this little gadget could completely change how you travel. And the base level AirFly SE is 35% off for Black Friday at Amazon.
The AirFly Pro lets me enjoy in-flight entertainment
The AirFly Pro from Twelve South is a minimally designed dongle that allows me to connect to the 3.5mm headphone jack in my airplane seat, enabling me to listen to in-flight entertainment on my noise-canceling earbuds.
All I have to do is pair the AirFly with the Bluetooth headphones I’m using, such as my AirPods Pro, plug the AirFly into the display in front of me, and I’m all set. I don’t even need to use my phone to connect the two devices.
There are several versions of the AirFly: the AirFly SE, which is currently on sale for $26 on Amazon and connects to just one set of headphones, the AirFly Pro at $55, the Pro V2 at $60 and the Pro 2 Deluxe at $70, which comes with an international headphone adapter and a suede travel case.
Hey, did you know? CNET Deals texts are free, easy and save you money.
I use the AirFly Pro, which has been a game-changer for me on flights. I’ve never had to worry about battery life since the AirFly Pro lasts for over 25 hours and can be fully charged in just three hours. I can also pair two separate pairs of headphones to a single AirFly Pro, in case I’m with someone else on a flight and want to watch the same movie or show.
And if that’s not enough, the AirFly Pro also doubles as an audio transmitter, allowing me to turn any speaker with a headphone jack, such as my old car stereo, into a Bluetooth speaker.
The AirFly Pro makes a great gift for any traveler
The AirFly Pro is the perfect present to give to someone who’s planning to travel this year. Besides my Anker MagSafe battery pack, the AirFly Pro has become my most treasured travel accessory when I fly, which is why I consider it one of those can’t-go-wrong gifts.
