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.

Wikipedia Says It’s Losing Traffic Due to AI Summaries, Social Media Videos
The popular online encyclopedia saw an 8% drop in pageviews over the last few months.

Wikipedia has seen a decline in users this year due to artificial intelligence summaries in search engine results and the growing popularity of social media, according to a blog post Friday from Marshall Miller of the Wikimedia Foundation, the organization that oversees the free online encyclopedia.
Don’t miss any of our unbiased tech content and lab-based reviews. Add CNET as a preferred Google source.
In the post, Miller describes an 8% drop in human pageviews over the last few months compared with the numbers Wikipedia saw in the same months in 2024.
«We believe that these declines reflect the impact of generative AI and social media on how people seek information, especially with search engines providing answers directly to searchers, often based on Wikipedia content,» Miller wrote.
Blame the bots
AI-generated summaries that pop up on search engines like Bing and Google often use bots called web crawlers to gather much of the information that users read at the top of the search results.
Websites do their best to restrict how these bots handle their data, but web crawlers have become pretty skilled at going undetected.
«Many bots that scrape websites like ours are continually getting more sophisticated and trying to appear human,» Miller wrote.
After reclassifying Wikipedia traffic data from earlier this year, Miller says the site «found that much of the unusually high traffic for the period of May and June was coming from bots built to evade detection.»
The Wikipedia blog post also noted that younger generations are turning to social-video platforms for their information rather than the open web and such sites as Wikipedia.
When people search with AI, they’re less likely to click through
There is now promising research on the impact of generative AI on the internet, especially concerning online publishers with business models that rely on users visiting their webpages.
(Disclosure: Ziff Davis, CNET’s parent company, in April filed a lawsuit against OpenAI, alleging it infringed Ziff Davis copyrights in training and operating its AI systems.)
In July, Pew Research examined browsing data from 900 US adults and found that the AI-generated summaries at the top of Google’s search results affected web traffic. When the summary appeared in a search, users were less likely to click on links compared to when the search results didn’t include the summaries.
Google search is especially important, because Google.com is the world’s most visited website — it’s how most of us find what we’re looking for on the internet.
«LLMs, AI chatbots, search engines and social platforms that use Wikipedia content must encourage more visitors to Wikipedia, so that the free knowledge that so many people and platforms depend on can continue to flow sustainably,» Miller wrote. «With fewer visits to Wikipedia, fewer volunteers may grow and enrich the content, and fewer individual donors may support this work.»
Last year, CNET published an extensive report on how changes in Google’s search algorithm decimated web traffic for online publishers.

OpenAI Says It’s Working With Actors to Crack Down on Celebrity Deepfakes in Sora
Bryan Cranston alerted SAG-AFTRA, the actors union, when he saw AI-generated videos of himself made with the AI video app.

OpenAI said Monday it would do more to stop users of its AI video generation app Sora from creating clips with the likenesses of actors and other celebrities after actor Bryan Cranston and the union representing film and TV actors raised concerns that deepfake videos were being made without the performers’ consent.
Actor Bryan Cranston, the Screen Actors Guild-American Federation of Television and Radio Artists (SAG-AFTRA) and several talent agencies said they struck a deal with the ChatGPT maker over the use of celebrities’ likenesses in Sora. The joint statement highlights the intense conflict between AI companies and rights holders like celebrities’ estates, movie studios and talent agencies — and how generative AI tech continues to erode reality for all of us.
Sora, a new sister app to ChatGPT, lets users create and share AI-generated videos. It launched to much fanfare three weeks ago, with AI enthusiasts searching for invite codes. But Sora is unique among AI video generators and social media apps; it lets you use other people’s recorded likenesses to place them in nearly any AI video. It has been, at best, weird and funny, and at worst, a never-ending scroll of deepfakes that are nearly indistinguishable from reality.
Cranston noticed his likeness was being used by Sora users when the app launched, and the Breaking Bad actor alerted his union. The new agreement with the actors’ union and talent agencies reiterates that celebrities will have to opt in to having their likenesses available to be placed into AI-generated video. OpenAI said in the statement that it has «strengthened the guardrails around replication of voice and likeness» and «expressed regret for these unintentional generations.»
OpenAI does have guardrails in place to prevent the creation of videos of well-known people: It rejected my prompt asking for a video of Taylor Swift on stage, for example. But these guardrails aren’t perfect, as we’ve saw last week with a growing trend of people creating videos featuring Rev. Martin Luther King Jr. They ranged from weird deepfakes of the civil rights leader rapping and wrestling in the WWE to overtly racist content.

The flood of «disrespectful depictions,» as OpenAI called them in a statement on Friday, is part of why the company paused the ability to create videos featuring King.
Statement from OpenAI and King Estate, Inc.
The Estate of Martin Luther King, Jr., Inc. (King, Inc.) and OpenAI have worked together to address how Dr. Martin Luther King Jr.’s likeness is represented in Sora generations. Some users generated disrespectful depictions of Dr.…— OpenAI Newsroom (@OpenAINewsroom) October 17, 2025
Bernice A. King, his daughter, last week publicly asked people to stop sending her AI-generated videos of her father. She was echoing comedian Robin Williams’ daughter, Zelda, who called these sorts of AI videos «gross.»
I concur concerning my father.
Please stop. #RobinWilliams #MLK #AI https://t.co/SImVIP30iN— Be A King (@BerniceKing) October 7, 2025
OpenAI said it «believes public figures and their families should ultimately have control over how their likeness is used» and that «authorized representatives» of public figures and their estates can request that their likeness not be included in Sora. In this case, King’s estate is the entity responsible for choosing how his likeness is used.
This isn’t the first time OpenAI has leaned on others to make those calls. Before Sora’s launch, the company reportedly told a number of Hollywood-adjacent talent agencies that they would have to opt out of having their intellectual property included in Sora. But that initial approach didn’t square with decades of copyright law — usually, companies need to license protected content before using it — and OpenAI reversed its stance a few days later. It’s one example of how AI companies and creators are clashing over copyright, including through high-profile lawsuits.
