Comet Nishimura Survives Brush With the Sun and Enters Evening Sky

The space snowball is now heading back out to deep space for the next four hundred years, but it might be possible to catch it as it goes.

The brightest comet of 2023 is still intact after making a hairpin turn around the sun over the weekend.

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 made its close pass by the sun on Sept. 17 before being flung back out to deep space.

Under dark skies, the comet is easily visible with the naked eye. Unfortunately, as it recedes to the outer limits of the solar system, it is best viewed low on the horizon just after sunset, when it can be washed out by fading daylight.

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.

However, it’s encouraging that Nishimura survived its encounter with the sun and there is always a chance it could brighten as it passes by Earth’s orbit.

How to catch the comet

This comet is trickier to see than other bright comets of the recent pass due to its low angle to the horizon, which is really a reflection of how close it passed by the sun. This is why it’s been most visible before sunrise on its way toward the sun and now after sunset as it recedes into space.

«It’s really best seen with binoculars or a telescope,» Alison Klesman, who holds a doctorate in 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.

The comet has met some serious resistance during its journey in the form of blasts of charged particles and plasma issuing forth from a tumultuous sun. Observers like astrophotographer Michael Jaeger (see above) watched earlier this month 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.

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.

Ring’s Latest Feature Lets You Verify Shared Security Videos

With so many fake videos out there, the home-security company is adding a level of protection.

Popular home security brand Ring announced that videos shared from its devices can now be verified, so customers know they’re watching an authentic, unaltered video. Ring says the new verification process is similar to a security seal on a package or medicine bottle, indicating that no one has tampered with it.

The new feature is available starting Thursday, and it doesn’t matter which Ring device recorded the video. All videos downloaded directly from the Ring app are automatically verified and include a security seal for authenticity.

Don’t miss any of our unbiased tech content and lab-based reviews. Add CNET as a preferred Google source.

When someone sends you a Ring video, you can now visit Ring’s verification page, paste the video link, and determine immediately whether the video is verified. The website doesn’t send your video anywhere. It stays locally on your device, and all verification checks happen within your browser. The verification website only accepts MP4 files, the format Ring videos are saved.

Videos downloaded before December 2025 or edited videos cannot be verified. Ring says that even minor adjustments, such as shaving a couple of seconds off the beginning or end of a video, or even adjusting brightness levels, will render it unverifiable.
