Are you ready for fall? The official arrival of fall is the autumnal equinox, which occurs in the Northern Hemisphere on Monday.

After a hot summer, the September equinox marks a welcome shift in the seasons for many folks. But what exactly is an equinox? It’s all about Earth and its relationship with the sun. Here’s how to understand, visualize and celebrate the autumnal equinox.

When is the fall equinox?

This year, the autumnal equinox in the Northern Hemisphere falls on Monday, Sept. 22. If you want to be extra specific and mark it on your calendar, mark it for 11:19 a.m. PT.

Dates can shift slightly for equinoxes depending on the year, but it’s always around this time in September. The next vernal equinox in the Northern Hemisphere takes place on March 20, 2026, and will mark the start of spring.

What is the autumn equinox?

The meaning of equinox is right there in the name: a combination of the Latin words for equal and night. 

«There are only two times of the year when the Earth’s axis is tilted neither toward nor away from the sun, resulting in a ‘nearly’ equal amount of daylight and darkness at all latitudes,» the National Weather Service said in an explainer about the seasons. 

The Earth spins on an axis (imagine a line running from pole to pole) and the planet sports a jaunty 23.5-degree tilt. The tilt is what gives us seasons. As the Earth orbits the sun, the tilt means some areas of the planet get more direct sunlight than others. That’s how it can be summer in the Northern Hemisphere (tilted toward the sun) and winter in the Southern Hemisphere (tilted away from the sun) at the same time. During the equinox, the sun shines straight at the equator and gives equal love to the two hemispheres.

Other planets that are also tilted on their axes of rotation also experience equinoxes. The time scales can be very different, however. An equinox on Saturn only comes around about every 15 Earth years. That means each season lasts for over seven years on Saturn. It’s even wilder on Neptune, which has seasons that last decades. We can be grateful for the relatively short seasons on our planet.

What does an equinox look like?

Wherever you are on Earth on the day of the equinox (and whether it’s a spring or fall equinox, depending on which hemisphere you live in), the sun will rise as close to east and set as close to west as possible, making it a foolproof compass. Go outside and watch the sunset and sunrise, and make a note of the landmarks in front of the sun. That way, you’ll always know what exactly is west and east.

The two annual equinoxes also feature the fastest sunrise and sunset of the year, with the sun taking just a few seconds to appear and disappear. That’s because this is the steepest angle at which the sun rises and sets during the year.

How is an equinox different from a solstice?

As with equinoxes, solstices are associated with Earth’s tilt, but instead of daylight and nighttime being even, the days and nights are at their extremes. The winter solstice is the shortest day of the year, while the summer solstice is the longest. This year, the winter solstice for the Northern Hemisphere falls on Sunday, Dec. 21.

What does the equinox look like from space?

Earth-watching satellites up in orbit have a unique view of the equinox. A NASA Earth Observatory video shows Earth from space and how the positioning of the sun’s light shifts with the changing of the seasons. It’s a great way to visualize what’s happening during our planet’s orbit around the sun. 

Celebrating the autumn equinox

Equinoxes aren’t like eclipses or meteors. There isn’t a big wow moment when you see something spectacular. The fall equinox this year will look like any other day, but it’s a handy way to mark the changing of the astronomical seasons. You can go around and declare, «It’s officially the first day of autumn!» How you celebrate is up to you. Here’s a suggestion: Put on your favorite sweater, go for a scenic foliage drive, sip a pumpkin spice latte and keep an eye out for those giant Halloween skeletons.

Google Discover, Google’s personalized news feed, has largely remained the same since its introduction in 2018, but it’s now receiving some new and helpful features. 

On Wednesday, Google announced that Discover will soon expand the type of content found within the feed and allow you to follow publications and creators. You can find Google Discover in the Google app, and it will be built into the home screens of some Android phones.

Instead of just seeing a list of web pages to visit on your feed, you’ll soon see a mix of web articles, YouTube videos and social media posts from X and Instagram, effectively widening the net of content shown in Discover. 

Along with expanding content from more sources, Google Discover is allowing users to follow specific publishers and content creators using a «follow» button at the top right of each content card. 

Google says that tapping the publication’s or creator’s name will open a new page previewing the content that’s typically shared before you choose to follow the outlet. From our testing across multiple phones so far, it appears the feature is still rolling out. 

Your Google Discover feed should now allow you to follow content creators. A more diversified mix of content will roll out over the coming weeks. 

If you live in Michigan, you might not be able to legally use a VPN soon if a new bill is passed into law. On Sept. 11, Michigan Republican representatives proposed far-reaching legislation banning adult internet content. 

The bill, called the Anticorruption of Public Morals Act and advanced by six Republican representatives, would ban a wide variety of adult content online, ranging from ASMR and adult manga to AI content and any depiction of transgender people. It also seeks to ban all use of VPNs, foreign or US-produced.

VPNs, or virtual private networks, are software suites often used as workarounds to avoid similar content bans that have passed in states like Texas, Louisiana, Mississippi and the UK. VPNs can be purchased with subscriptions or downloaded and are also built into some browsers and Wi-Fi routers.

But Michigan’s bill would charge internet service providers with detecting and blocking VPN use, as well as banning the sale of VPNs in the state. Associated fines would be up to $500,000.

What the ban could mean for VPNs

Unlike some laws banning access to adult content, this Michigan bill is comprehensive. It applies to all residents of Michigan, adults or children, targets an extensive range of content and includes language that could ban not only VPNs but any method of bypassing internet filters or restrictions. 

That could spell trouble for VPN owners and other internet users who leverage these tools to improve their privacy, protect their identities online, prevent ISPs from gathering data about them or increase their device safety when browsing on public Wi-Fi.

Bills like these could have unintended side effects. John Perrino, Senior Policy and Advocacy Expert for the nonprofit Internet Society, mentioned to CNET that adult content laws like this could interfere with what kind of music people can stream, the sexual health forums and articles they can access and even important news involving sexual topics that they may want to read.

 «Additionally, state age verification laws are difficult for smaller services to comply with, hurting competition and an open internet,» Perrino said.

The Anticorruption of Public Morals Act has not passed the Michigan House of Representatives committee or been voted on by the Michigan Senate, and it’s not clear how much support the bill has beyond the six Republican representatives who have proposed it. As we’ve seen with state legislation in the past, sometimes bills like these can serve as templates for other representatives who may want to propose similar laws in their own states.

Could VPNs still get around bans like these?

Could VPNs still get around this type of ban? That’s a complex question that this bill doesn’t really address. 

«From a technical standpoint, ISPs can attempt to distinguish VPN traffic using deep packet inspection, or they can block known VPN IP addresses,» said NordVPN privacy advocate Laura Tyrylyte. «However, deploying them effectively requires big investments and ongoing maintenance, making large-scale VPN blocking both costly and complex.»

Also, VPNs have ways around deep packet inspection and other methods. 

«Some VPNs offer obfuscation — which tries to disguise VPN traffic as standard web traffic — using dedicated servers or custom VPN protocols, like NordVPN’s NordWhisper or Proton VPN’s Stealth,» said CNET senior editor Moe Long. «But note that obfuscation isn’t foolproof.»

There are also no-log features offered by many VPNs to guarantee they don’t keep a record of your activity, and no-log audits from third parties like Deloitte that — well, try to guarantee the guarantee. VPNs can even use server tricks, such as RAM-only servers that automatically reboot to erase data after every browsing session.

If you’re seriously concerned about your data privacy, you can look for features like these in a VPN and see if they are right for you. Changes like these, even on the state level, are one reason we pay close attention to how specific VPNs work during our testing, and recommend the right VPNs for the job, from speedy browsing to privacy while traveling.
