How to Actually See the September Equinox This Weekend
It’s an important annual milestone: autumn equinox north of the equator and spring equinox to the south.
The September equinox arrives on Saturday morning (late Friday PT), signaling a shift in seasons.
The fact that the September and March equinoxes, along with December and June solstices, happen at the same time each year suggests the milestones have something to do with Earth’s year-long journey around the sun. And, of course, they do, but there’s more going on.
On the equinox the sun appears directly over the equator, which means that daylight and nighttime hours are roughly equal around the globe, hence the word equinox.
But if you picture a diagram of the solar system with all the planets in the same plane orbiting the sun endlessly, you might ask why it isn’t equinox every day instead of just two days a year? This is because of a weird quirk of our world, which is that Earth doesn’t rotate on its axis straight up and down; instead the planet is tilted by 23.5 degrees.
This is actually what gives us our seasons. When Earth is at the point in its orbit where the north pole is tilted toward the sun, that’s summer in the northern hemisphere and also the time of year when the sun is higher in the sky. The moment when the sun is highest in the sky in the north is the June solstice. When it’s lowest in the sky in the north and highest in the south, that’s the December solstice.
The equinoxes are the midway points between the two solstices, the moment Earth crosses the point in its orbit when one hemisphere begins to receive more sun than the other. Or, astronomically speaking, the moment one of Earth’s poles transitions to be closer to the sun than the other. This happens next at 11:50 p.m. PT Friday, which will be Saturday morning or afternoon for much of the rest of the world.
How do I see it?
An equinox is really just a milestone along our 365.25-day journey around the sun, but there are a few ways to see it, kind of.
No matter where you are on Earth on equinox day, the sun will rise as close to due east and set as close to due west as it ever will. It’s the one day the sun is a pretty foolproof compass. This makes the equinox a handy day for wayfinding. If you go outside at sunrise Saturday, take note of any landmarks directly in front of the sun as it rises. Now you’ll know with confidence that those landmarks are due east from your location. Same goes for anything in front of the setting sun in the west.
Pay close attention and you’ll notice something else about an equinox sunrise and sunset — they go by more quickly than on any other day of the year. Because the sun is rising due east and setting almost perfectly west, it’s also coming up and going down at the steepest angle of the year. This means it takes fewer seconds for the full disc of the sun to emerge above the horizon and then disappear below it again in the evening.
The actual difference between the fastest sunset and the slowest sunset, which is — you guessed it — on the solstice, is only about 30 seconds at middle latitudes. In other words, an equinox sunrise is faster by about one-sixth compared to a solstice sunrise. Try timing it and marking it on your calendar and then doing the same in three months at the next solstice.

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.
