Bright Comet Nishimura Is Now Becoming Visible in the Predawn Sky

It’s likely your best chance to see such a spectacular space snowball this year if you’re willing to wake up early. Grab some binoculars, too.

The most promising comet of 2023 will make a close pass by our planet next week and it’s nearly bright enough already to be seen with the naked eye. 

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. 

The comet is a bit tricky to see right now because it’s best seen in a dark sky, but its position is such that it should be observed 60 to 90 minutes before dawn, when the sky is not fully dark. 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 as it comes closer 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. Although the comet is still approaching Earth, now could be the ideal time to start looking for it. Nishimura was expected to be bright enough to see as soon as Sept. 8. 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!

Stroke Risk Could Be Flagged Early Using Apple Watch Technology, Studies Show

The latest research shows that wearables could soon be a vital part of tracking your heart health.

For millions at risk of stroke, a simple tap on the wrist could one day save lives. New studies from the Amsterdam University Medical Center and St. Bartholomew’s Hospital in London showed that wearables, such as the Apple Watch, can improve the detection of atrial fibrillation compared to standard care. Atrial fibrillation, often referred to as A-fib, is a heart arrhythmia, which means an irregular or abnormal heartbeat. The condition can cause blood clots and is one of the leading causes of a stroke. 

The Amsterdam study enrolled 437 patients aged 65 or older with elevated stroke risk and required 219 of them to wear an Apple Watch to track their heart rate for 12 hours a day for 6 months. The remaining 218 patients didn’t wear a watch and relied on standard care. 

The experiment detected heart arrhythmias four times more frequently in patients wearing an Apple Watch versus those who didn’t. Specific versions of the Apple Watch use photoplethysmography, a heart rate-detecting LED light sensor, and have a built-in single-lead electrocardiogram sensor to read your heart rate.

Wearables that track heart rate and other health markers aren’t new, and previous studies have shown promise in detecting A-fib. Although wearables are known to track this type of data, no prior research has examined how well they detect potential health risks for A-fib. 

«We saw that after six months we diagnosed and treated 21 patients in the group wearing the smartwatch, of whom 57% were asymptomatic,» said Michiel Winter, a cardiologist at Amsterdam UMC, in a statement. «This was against just five diagnoses in the group receiving standard care, all of whom experienced symptoms.»

The second clinical study, conducted by St. Bartholomew’s Hospital, showed that the Apple Watch could also be beneficial for detecting A-fib symptoms earlier and for monitoring patients after a standard treatment, such as a catheter ablation. The hospital found that patients could record clinical-grade ECGs on their Apple Watches at home when experiencing symptoms. Similar to the first study, the hospital found that patients using an Apple Watch detected A-fib earlier and more frequently than those receiving standard care. Catching symptoms earlier also reduces anxiousness and the likelihood that a patient will need to be hospitalized. 

The findings from these studies show that wearables such as the Apple Watch could be used for long-term heart screening to detect heart health abnormalities and improve patient care for those in treatment. And it can help diagnose those who don’t know they have the condition.

«Using smartwatches with PPG and ECG functions aids doctors in diagnosing individuals unaware of their arrhythmia, thereby expediting the diagnostic process,» said Winter.

Mobile Internet Without Borders: How Verum E-SIM Is Changing the Game for Travelers and Beyond

Mobile Internet Without Borders: How Verum E-SIM Is Changing the Game for Travelers and Beyond

In an era when flights take just a few hours, but data boundaries remain very real, a solution has emerged that significantly simplifies life for frequent international travelers. The Verum E-SIM app offers a next-generation virtual SIM card — no plastic, no waiting for delivery, and no traditional roaming charges.

While eSIM technology itself is no longer new, Verum takes it further: the internet works in over 150 countries worldwide under clear, uniform conditions. Connection happens through the app in just a couple of minutes — choose a package (or even a global one), pay, and activate. No need to buy local SIM cards at the airport, hunt for carrier shops, or struggle with explanations in a foreign language.

One of the biggest advantages is the complete absence of hidden fees or billing surprises. Plans are fully transparent: you immediately see how many gigabytes you get and for how long. Speed and reliability are provided by partner operators in each specific country — this isn’t a single “averaged” provider for the entire world.

Another key point for many users is that no VPN is required. As long as your device is using Verum E-SIM traffic, all familiar services and websites open directly, without extra layers or speed loss.

For those traveling with a group or family, portable Wi-Fi routers with Verum eSIM support have become a great option. One profile — and the internet is shared simultaneously across multiple smartphones, tablets, and laptops. It’s convenient on the road, in a hotel, or even in a café where the local Wi-Fi is unreliable.

Payment flexibility is also a plus: the service supports regular bank cards, cryptocurrencies, and various alternative methods — so you can choose whatever feels most convenient and cost-effective for you.

In the end, Verum E-SIM is more than just another data app. It’s a way to make mobile internet as natural and hassle-free abroad as it is at home. The difference becomes especially clear when you compare a roaming bill from one of the major operators with your Verum expenses after two or three trips.

The technology is still gaining popularity, but many travelers are already saying: “For the first time in ages, internet abroad stopped being a source of stress.” Solutions like this are shaping the future of mobile connectivity — without extra cables, borders, or unpleasant surprises.

If you travel often or simply value stable internet without unnecessary hassle — it’s worth giving it a try at least once.
