Saturn’s Pulling a Stunt This Weekend That Hasn’t Happened Since 2009: How to Watch
As Saturn and Earth line up, Saturn’s iconic rings will appear to vanish.
It’s not every day that a prominent feature of our solar system disappears, but that’s precisely what will happen with Saturn. Over the weekend, Saturn’s gorgeous rings will nearly vanish from sight. No worries, they’ll be back in a couple of weeks.
This phenomenon is caused by an optical illusion that occurs when the stars line up. Saturn is tilted at 26.73 degrees on its orbit, while Earth is very close to that at a 23.5-degree tilt. When the two planets line up just right, the rings of Saturn are almost entirely horizontal from the perspective of Earth, causing them to mostly vanish.

«As Saturn and the Earth travel around the sun, we will periodically be in a position where those rings are seen edge on,» explains Dr. Shannon Schmoll, director of the Abrams Planetarium at Michigan State University. «Because the rings are so thin, if we look at it edge-on, we can’t see (the rings).»
So, anyone looking up at the sky this weekend will likely note that the planet won’t look very Saturn-like without its trademark rings. However, if you’re using a powerful telescope, the rings will still be visible. It’ll appear as though a thin line is running through the middle of Saturn, as shown in the graphic above.
How do Saturn’s rings disappear?
The tilt of Saturn and Earth is the main thing. It’s like looking at a piece of paper. If you hold it horizontally up to eye level, it’ll be practically invisible. Paper is an apt analogy here because Saturn’s rings are thinner than many think.
«The rings of Saturn are incredibly thin,» Schmoll says. «Even the thickest estimates put the rings at 1 kilometer (about half a mile). Saturn’s diameter is over 116,000 km, so comparatively that is VERY thin.»
According to NASA, Saturn’s rings average about 30 feet in height across the entire length of the ring. That means when viewed from the side at a distance of about 1.5 million kilometers (983,000 miles), you might as well be looking at a sheet of paper from the side.
The rings are still technically visible. Folks with higher-powered telescopes may be able to see the line jutting across Saturn. However, those with low-power telescopes may not see it, making Saturn look naked.
When will the rings return?
The peak of this little celestial dance will occur over the weekend. So, technically, the rings have already been like this for a week or two and will continue to be difficult to see going into April. By then, Saturn’s orbit will begin to tilt the rings again, and they will slowly come back into view over the next month or two.
«Technically, the ring plane crossing is only for a moment when it’s fully edge on,» said Schmoll. «For powerful telescopes, we can see the rings again quickly. For most backyard telescopes, though, you have to wait a few months before you can see them again»
How rare is this event?
According to NASA, this happens about every 13 to 15 years on average. It’s not an exact science, though, as prior events occurred in 1980, 1995 and 2009.
«Saturn’s orbit is just under 30 years, so there are two times in a Saturn orbit when that angle is just right,» Dr. Schmoll says. «Sometimes it happens when Saturn is on the opposite side of the sun from us, which makes it hard to see because the sun gets in the way.»
The next one is predicted to come in 2038 or 2039, Schmoll says, and it should be «a lot easier to spot» as well.

Google races to put Gemini at the center of Android before Apple’s AI reboot
Google is using its latest Android rollout to position Gemini as the AI layer across phones, Chrome, laptops and cars.
Google is using its latest Android rollout to make Gemini less of a chatbot and more of an operating layer across the phone, browser, car and laptop, just weeks before Apple is expected to show its own Gemini-powered Apple Intelligence reboot at WWDC.
Ahead of its Google I/O developer conference next week, the company previewed a number of Android updates, including AI-powered app automation, a smarter version of Chrome on Android, new tools for creators, a redesigned Android Auto experience, and a sweeping set of new security features.
Alphabet is counting on Gemini to help Google compete directly with OpenAI and Anthropic in the market for artificial intelligence models and services, while also serving as the AI backbone across its expansive portfolio of products, including Android. Meanwhile, Gemini is powering part of Apple’s new AI strategy, giving Google a role in the iPhone maker’s reset even as it races to prove its own version of personal AI on the phone is further along.
Sameer Samat, who oversees Google’s Android ecosystem, told CNBC that Google is rebuilding parts of Android around Gemini Intelligence to help users complete everyday tasks more easily.
“We’re transitioning from an operating system to an intelligence system,” he said.
As part of Tuesday’s announcements. Google said Gemini Intelligence will be able to move across apps, understand what’s on the screen and complete tasks that would normally require a user to jump between multiple services. That means Android is moving beyond the traditional assistant model, where users ask a question and get an answer, and acting more like an agent.
For instance, Google says Gemini can pull relevant information from Gmail, build shopping carts and book reservations. Samat gave the example of asking Gemini to look at the guest list for a barbecue, build a menu, add ingredients to an Instacart list and return for approval before checkout.
A big concern surrounding agentic AI involves software taking action on a user’s behalf without permissions. Samat said Gemini will come back to the user before completing a transaction, adding, “the human is always in the loop.”
Four months after announcing its Gemini deal with Google, Apple is under pressure to show a more capable version of Apple Intelligence, which has been a relative laggard on the market. Apple has long framed privacy, hardware integration and control of the user experience as its advantages.
Google’s Android push is designed to show it can bring AI deeper into the device experience while still giving users control over what Gemini can see, where it can act and when it needs confirmation.
The app automation features will roll out in waves, starting with the latest Samsung Galaxy and Google Pixel phones this summer, before expanding across more Android devices, including watches, cars, glasses and laptops later this year.
The company is also redesigning Android Auto around Gemini, turning the car into another major surface for its assistant. Android Auto is in more than 250 million cars, and Google says the new release includes its biggest maps update in a decade and Gemini-powered help with tasks like ordering dinner while driving.
Alphabet’s AI strategy has been embraced by Wall Street, which has pushed the company’s stock price up more than 140% in the past year, compared to Apple’s roughly 40% gain. Investors now want to see how Gemini can become more central to the products people use every day.

Waymo recalls 3,800 robotaxis after glitch allowed some vehicles to ‘drive into standing water’
Waymo issued a voluntary recall of about 3,800 of its robotaxis to fix software issues that could allow them to drive into flooded roadways.
Waymo is recalling about 3,800 robotaxis in the U.S. to fix software issues that could allow them to “drive onto a flooded roadway,” according to a letter on the National Highway Traffic Safety Administration’s website.
The voluntary recall is for Waymo vehicles that use the company’s fifth and sixth generation automated driving systems (or ADS), the U.S. auto safety regulator said in the letter posted Tuesday.
Waymo autonomous vehicles in Austin, Texas, were seen on camera driving onto a flooded street and stalling, requiring other drivers to navigate around them. It’s the latest example of a safety-related issue for the Alphabet-owned AV unit that’s rapidly bolstering its fleet of vehicles and entering new U.S. markets.
Waymo has drawn criticism for its vehicles failing to yield to school buses in Austin, and for the performance of its vehicles during widespread power outages in San Francisco in December, when robotaxis halted in traffic, causing gridlock.
The company said in a statement on Tuesday that it’s “identified an area of improvement regarding untraversable flooded lanes specific to higher-speed roadways,” and opted to file a “voluntary software recall” with the NHTSA.
“Waymo provides over half a million trips every week in some of the most challenging driving environments across the U.S., and safety is our primary priority,” the company said.
Waymo added that it’s working on “additional software safeguards” and has put “mitigations” in place, limiting where its robotaxis operate during extreme weather, so that they avoid “areas where flash flooding might occur” in periods of intense rain.

Qualcomm tumbles 13% as semiconductor stocks retreat from historic AI-fueled surge
Semiconductor equities reversed sharply after a broad AI-driven advance, with Qualcomm suffering its worst day since 2020 amid inflation concerns and rising oil prices.
Semiconductor stocks fell sharply on Tuesday, reversing course after an extensive rally that had expanded the artificial intelligence investment theme well past Nvidia and driven the industry to unprecedented levels.
Qualcomm plunged 13% and was on track for its steepest single-day decline since 2020. Intel shed 8%, while On Semiconductor and Skyworks Solutions each lost more than 6%. The iShares Semiconductor ETF, which benchmarks the overall sector, fell 5%.
The sell-off came after a key gauge of consumer prices came in above forecasts, and as conflict in Iran pushed crude oil higher—prompting investors to shift away from riskier assets.
The preceding advance had widened the AI opportunity set beyond longtime industry leader Nvidia, which for much of the past several years had largely carried the market to new peaks on its own.
Explosive appetite for central processing units, along with the graphics processing units that power large language models, has sent chipmakers to all-time highs.
Market participants are wagering that the shift from AI model training to autonomous agents will lift demand for additional AI hardware. Among the beneficiaries are memory chip producers, which are raising prices as supply remains tight.
Micron Technology slid 6%, and Sandisk cratered 8%. Sandisk’s stock has surged more than six times over since January.
