Meteor Shower Season Heats Up as Orionids and Taurids Activate

Earth is set to pass through a series of dusty clouds of space debris from Halley’s Comet and others that promise to light up night skies.

August’s Perseid meteor shower may be the most well known of the year, but it’s the last quarter of the year that brings the most shooting-star and fireball action to night skies.

As of this week, both the Orionid and Southern Taurid meteor showers are active. While the Orionids aren’t set to peak until around Oct. 20, they still add some shooting stars to each evening right away. The Taurids, on the other hand, don’t have a very defined peak and are forecast to be visible at a rate of around two per hour over the next several weeks.

Adding to the celestial drama is the Taurids’ reputation for delivering a number of bright fireballs streaking through the sky.

«In 2022, the Earth passed through a swarm of Taurid fireballs,» writes Bob Lunsford for the American Meteor Society. «This year we are further from this swarm but will still encounter some fireball activity.»

The Taurids can be traced to debris from the comet 2P/Encke, while the Orionids are connected to the leavings of the famed Halley’s Comet, which visits the inner solar system only about every 75 years. The celebrity snowball won’t be back until 2061.

Two distinct clouds from Halley’s Comet are responsible for both the Orionids each October and the Eta Aquariids meteor shower in May.

How to see the celestial show

When the Orionids peak between Oct 20 and 22, the conditions should be nearly perfect, especially with the moonless sky on the morning of the 22nd in the hours just before dawn. Most nights, the area near the constellation of Orion the Hunter where the Orionids appear to radiate from will be highest in the sky around 2 a.m. But it may be possible to see the meteors anytime between midnight and dawn.

The Orionids are known for zipping through the sky at relatively high speed and often leaving long trains that can linger for a second or two.

During those peak mornings, the number of Orionid meteors will suddenly increase to between 10 and 20 per hour, but sometimes Earth passes through a particularly dense pocket of debris and those rates shoot up to 50 to 70, rivaling the Perseids.

While it’s worth marking the Orionids’ peak on your calendar, you might be able to catch a handful of meteors and a fireball on any given night over the next several weeks.

If you have at least an hour free on a night with clear skies and a location away from light pollution, all you need to do is find an area with a broad view of the night sky. Allow at least 15 minutes for your eyes to adjust to the darkness and then just relax, lie back and watch.

You’ll hear seasoned skywatchers talking about orienting yourself to face the radiant of a particular meteor shower. The radiant is the section of the sky from which certain meteors will appear to radiate outward. Meteor showers are usually named for a constellation within that radiant, so the Orionids are named for Orion.

If you can locate Orion in the sky and orient yourself in that direction, it might boost your viewing experience slightly. But the reality is that most amateurs won’t notice a difference. It’s far more important to have dark skies away from light pollution and the widest view of the sky possible. While meteors might originate from a certain radiant, they go all over the sky from that point, so it really doesn’t matter much which way you face.

Plus, there are more than Orionids up there on most nights. There are also the aforementioned Taurids, smaller showers like the Anthelion and even sporadic meteors that aren’t part of defined showers.

So just plan for at least an hour outside, preferably between midnight and dawn, for the best chance to make it through lulls in activity and spotting a few meteors. Be sure to bring all you need to be comfortable that long: Blankets, snacks and drinks are a good idea. Good luck!

How Much Energy Do Your AI Prompts Consume? Google Just Shared Its Gemini Numbers

Current measurements of AI’s impact aren’t telling the full story. Google has offered a new method it hopes to standardize.

The explosion of AI tools worldwide is increasing exponentially, but the companies that make these tools often don’t express their environmental impact in detail.

Google has just released a technical paper detailing measurements for energy, emissions and water use of its Gemini AI prompts. The impact of a single prompt is, it says, minuscule. According to its methodology for measuring AI’s impact, a single prompt’s energy consumption is about the equivalent of watching TV for less than 9 seconds.

That’s quite in a single serving, except when you consider the variety of chatbots being used, with billions of prompts easily sent every day.

On the more positive side of progress, the technology behind these prompts has become more efficient. Over the past 12 months, the energy of a single Gemini text prompt has been reduced by 33x, and the total carbon footprint has been reduced by 44x, Google says. According to the tech giant, that’s not unsubstantial, and it’s a momentum that will need to be maintained going forward.

Google did not immediately respond to CNET’s request for further comment.

Google’s calculation method considers much more

The typical calculation for the energy cost of an AI prompt ends at the active machine it’s been run on, which shows a much smaller per-prompt footprint. But Google’s method for measuring the impact of a prompt purportedly spans a much wider range of factors that paint a clearer picture, including full-system dynamic power, idle machines, data center overhead, water consumption and more.

For comparison, it’s estimated that only using the active TPU and GPU consumption, a single Gemini prompt uses 0.10 watt-hours of energy, 0.12 milliliters of water and emits 0.02 grams of carbon dioxide equivalent. This is a promising number, but Google’s wider methodology tells a different story. With more considerations in place, a Gemini text prompt uses 0.24Wh of energy, 0.26mL of water and emits 0.03 gCO2e — around double across the board.

Will new efficiencies keep up with AI use?

Through a multilayered series of efficiencies, Google is continually working on ways to make AI’s impact less burdensome, from more efficient model architectures and data centers to custom hardware.

With smarter models, use cases and tools emerging daily, those efficiencies will be critical as we immerse ourselves deeper in this AI reality.

For more, you should stop using ChatGPT for these things.

Vivo Launches Mixed-Reality Headset, an Apple Vision Pro Competitor

Vivo Vision has many of the same design elements as Apple’s VR/AR, but is only available in China, for now.

Look-alikes of Apple products often pop up in China, and mixed-reality headsets have now joined the party. Chinese smartphone maker Vivo has introduced the Vivo Vision, a headset mixing both AR and VR, and it bears many similarities to the Apple Vision Pro.

The company announced the Vivo Vision Discovery Edition at its 30th anniversary celebration in Dongguan, China, saying it’s «the first MR product developed by a smartphone manufacturer in China, positioning Vivo as the first Chinese company to operate within both the smartphone and MR product sectors.»

The Vivo Vision, currently only an in-store experience in mainland China, has a curved glass visor, an aluminum external battery pack and downward-pointing cameras like the Vision Pro. But it also has some differences — an 180-degree panoramic field of view and a much lighter weight at 398 grams (versus the Vision Pro’s 650 grams).

CNET asked Vivo if it plans to sell the Vivo Vision to non-China markets, but the company did not immediately respond.

The Vivo Vision runs on OriginOS Vision, Vivo’s mixed-reality operating system. It supports 3D video recording, spatial photos and audio, and a 120-foot cinematic screen experience.

The starting cost in China will be $1,395 (converted to US dollars), compared to the Vision Pro at $3,500.

Even if the Vivo Vision came to the consumer market in the US, it might not matter much to Apple’s bottom line. The Vision Pro hasn’t been a big seller, likely because of the price tag. Still, the headset market is expected to grow quickly over the next several years, and Apple is already working on new versions of the Vision Pro, including one that’s more affordable than the original.

Jon Rettinger, a tech influencer with more than 1.65 million YouTube subscribers, says he’s not overly enthusiastic about VR/AR just yet. «It’s heavy, invasive and without a must-have use case,» Rettinger told CNET. «If the technology can go from goggles to glasses, I think we’ll see a significant rise. But if the current form factors stay, it will always be niche.

The YouTuber loves that the technology exists, but still doesn’t use it. «The honeymoon wore off. Aside from some gaming and content viewing, it’s still cumbersome, and I tend to go back to my laptop,» he said.
