Have You Ever Seen a Black Moon? Neither Have We, but One Is Coming This Weekend

You’ve no doubt heard of supermoons, blue moons, mini moons and blood moons, but have you ever heard of a black moon?

Late last year, we were treated to four consecutive supermoons, where the moon is the biggest and brightest that it can possibly be in the night sky. Have you ever wondered what it’s called when the opposite happens? There is a name for it, and it’s happening this weekend — the emergence of the black moon.

The term black moon isn’t an official term, but rather a nickname for when a new moon fulfills certain conditions. Typically, each season has three new moons just like it has three full moons. However, when the stars align — pun intended — there is an extra cycle squeezed in. When this happens to full moons, it’s referred to as a «seasonal blue moon,» and this happens to a new moon, it’s called a black moon.

The weekend of Aug. 22 is such an occurrence. The first new moon of the summer came relatively early, on June 25, followed by the next one on July 24. The final new moon of the season comes on Sept. 21, which is the day before summer officially ends. Since there’s an extra new moon, the third new moon in the set of four is referred to as the black moon, which means August’s moon gets the distinction.

Two types of black moons

According to Dr. Shannon Schmoll, manager of Michigan State University’s Abrams Planetarium, a black moon is essentially the same as a blue moon, but for new moons instead of full moons. Thus, the same rules apply to both.

«A black moon tends to have two common definitions,» Schmoll tells CNET. «The less cumbersome one is the second full moon in a month. Because thelunar cycle is a bit shorter than most months, every once in a while, there will be a full moon at the very beginning and very end of amonth.»

Since the solar cycle is 29.5 days, as Schmoll notes, this can happen, and it does soabout once every 29 months.

The next occurrence of that type of blackmoon is slated for August 2027, when new moons will appear on Aug. 2 and Aug. 31. The last time this happened was in the spring of 2023.

«The other definition is the third full moon in a season with four,» says Schmoll. «So, a season here is the time between an equinox and a solstice. Becausethat is three months, we typically get three moons in that time. Every once in a while, we get four, and the third one is the ‘extra’ one. «

This occurs once every 33 months and is the rarer of the two types of black moons, making August’s new moon a little extra special. The next time this type of black moon is slated to happen is in summer 2028, when June and September’s new moons will take place during the summer once again, like they did this year.

For reference, blue moons are also fairly rare. The next blue moon is coming in May 2026 on the 1st and 31st of the month.

In the grand scheme, though, Schmoll says that these instances are quirks of our calendar system and «there isn’t anything astronomically significant about it» aside from it being a fun little coincidence.

You can’t see it, and that’s OK

We see the moon because it reflects light from the sun. During a new moon, our closest celestial neighbor is hidden behind the Earth, so sunlight can’t reach it. That means you won’t be able to see this rare celestial phenomenon even if you try, so for once, we recommend not bothering to look for it.

Per Schmoll, the only way to see a new moon is if there’s a solar eclipse when it slips in front of the sun.

However, there are other ways to enjoy a new moon: the moon is often cited as one of the most common and unavoidable sources of light pollution, making it harder to find things in the night sky. The Perseids meteor shower had its peak during August’s full moon, which made the more dimly lit meteors more difficult to see, even if you left the city and suburbs to get a darker sky.

With this year’s black moon, stargazers will get one additional night this summer of serene, moonless darkness in the night sky. This will give enthusiasts another great chance to spot six planets in the sky for the last six-planet parade we’ll see for a few years, and for photographers in the northern hemisphere to get some outstanding shots of the Milky Way galaxy. Since Perseids ends on Aug. 23, there’s also a chance you may see one of the final shooting stars from that meteor shower.

So, if you’ve been waiting for the darkest possible night to see some stars, this weekend is a great opportunity thanks to this year’s black moon.

Considering Buying a $20K Home Robot? There’s Something You Need to Know First

This robot is designed to do your chores for you — but it might need some help from a remote operator.

The robot stands 5 feet 6 inches tall, weighs as much as a golden retriever and is nearly the price of a brand-new budget car. This is Neo, the humanoid robot.

Billed as a personal assistant you can talk to and eventually rely on to handle everyday tasks, Neo could load your dishwasher and fold your laundry.

But it doesn’t come cheap: It’ll cost you $20,000. And even then, you’ll still need to train this new home bot, and it possibly requires remote assistance as well.

If that still sounds enticing, preorders are now open (for $200 down). You’ll be signing up as an early adopter for what Neo’s maker, a California-based company called 1X, is calling a «consumer-ready humanoid.» That’s opposed to other humanoids under development from the likes of Tesla and Figure, which are, for the moment at least, more focused on factory environments.

Neo is a whole order of magnitude different from robot vacuums like those from Roomba, Eufy and Ecovacs, and embodies a long-running sci-fi fantasy of robot maids and butlers doing chores and picking up after us. If this is the future, read on for more of what’s in store.

What the Neo robot can do around the house

The pitch from 1X is that Neo can do all manner of household chores: fold laundry, run a vacuum, tidy shelves and bring in the groceries. It can open doors, climb stairs and even act as a home entertainment system.

Neo appears to move smoothly, with a soft, almost human-like gait, thanks to 1X’s tendon-driven motor system that gives it gentle motion and impressive strength. The company says it can lift up to 154 pounds and carry 55 pounds, but it is quieter than a refrigerator. It’s covered in soft materials and neutral colors, making it look less intimidating than metallic prototypes from other companies.

The company says Neo has a 4-hour runtime. Its hands are IP68-rated, meaning they’re submersible in water. It can connect via Wi-Fi, Bluetooth and 5G. For conversation, it has a built-in large language model (LLM), the same sort of AI technology that powers ChatGPT and Gemini.

The primary way to control the Neo robot will be by speaking to it, just as if it were a person.

Still, Neo’s usefulness today depends heavily on how you define useful. The Wall Street Journal’s Joanna Stern got an up-close look at Neo at 1X’s headquarters and found that, at least for now, it’s largely teleoperated, meaning a human often operates it remotely using a virtual-reality headset and controllers.

«I didn’t see Neo do anything autonomously, although the company did share a video of Neo opening a door on its own,» Stern wrote last week. 1X CEO Bernt Børnich reportedly told her that Neo will do most things autonomously in 2026, though he also acknowledged that the quality «may lag at first.»

The company’s FAQ says that if there’s a chore request Neo doesn’t know how to accomplish, you can schedule an expert from 1X to help the robot «learn while getting the job done.»

What you need to know about Neo and privacy

Part of what early adopters are signing up for is to allow Neo to learn from their environment, so that future versions can operate more independently.

That learning process raises questions about privacy and trust. The robot uses a mix of visual, audio and contextual intelligence — meaning it can see, hear and remember interactions with you in your home.

«If you buy this product, it is because you’re OK with that social contract,» Børnich told the Journal. «It’s less about Neo instantly doing your chores and more about you helping Neo learn to do them safely and effectively.»

Neo’s reliance on human operation behind the scenes prompted a response from John Carmack, a computer industry luminary known for his work with VR systems and the lead programmer of classic video games, including Doom and Quake.

«Companies selling the dream of autonomous household humanoid robots today would be better off embracing reality and selling ‘remote operated household help’,» he wrote in a post on the X social network.

1X says it’s taking steps to protect your privacy: Neo listens only when it recognizes it’s being addressed, and its cameras will blur out humans. You can restrict Neo from entering or viewing specific areas of your home, and the robot will never be teleoperated without owner approval, the company says.

But inviting an AI-equipped humanoid to observe your home life isn’t a small step.

The first units are expected to ship to customers in the US in 2026. There is a $499 monthly subscription alternative to the $20,000 full purchase price, although it will be available at an unspecified later date. A broader international rollout is promised for 2027.

Neo’s got a long road ahead of it to live up to the expectations set by Rosie the Robot in The Jetsons way back when. But this is no Hanna-Barbera cartoon. What we’re seeing now is a much more tangible harbinger of change.

Here’s How to Relive Your Gaming History Spanning Decades Across Nintendo Consoles

Nintendo’s new store app includes a list of the games you’ve played and how long you played them.

Nintendo’s new iOS and Android app for its storefront makes it easier to browse and purchase games for the Nintendo Switch and Switch 2, but its most compelling feature is one that lays out your Nintendo gaming history by year.

Buried at the very bottom of your Profile page on the Nintendo Store app (you can get to it by tapping the icon with your Mii at the bottom right) is an option called Play Activity. At the top, your Recent Activity will display games you played recently and for how long. But scroll down through All Activity and you’ll find games and console apps stretching back years and years.

For me, it was a shock to see Wii U and Nintendo 3DS titles I’d forgotten all about, such as a game my daughters enjoyed — Art Academy: Home Studio — and Chibi-Robo! Zip Lash, which I played in 2015 for 10 days. I have no recollection of playing Steel Diver for Nintendo 3DS, but there’s evidence to prove that happened on March 28, 2011.

Why Play Activity matters

If the feature were just nostalgia for nostalgia’s sake, that would be one thing, but for anyone who has a long history across multiple Nintendo console generations, this is good information to have. In an era of remakes and re-releases, it’s helpful to know what games you actually have played before, what console you played them on and whether you spent much time on them. My Play Activity history is littered with games I only played for less than an hour, such as Ridge Racer 3D, and abandoned for others.

It reminds me that I played Nintendogs, the cute dog simulator, for a full four years, from 2011 to 2015. Why hasn’t Nintendo rebooted that franchise?

It’s useful that you can sort the play history by most recently played, date first played, total time played and by game system. I was surprised by how many titles I played on the Wii U, but it probably paled in comparison to the number of games I played on the GameCube or the original Wii. The Play Activity doesn’t appear to go back that far; for me, it stops at 2011 with the Wii U and 3DS. Games on the Switch appear to show more detail, showing you how much you played for each gaming session.

But most of all, it’s nice to have a document that charts your relationship with Nintendo’s systems and software, whether it’s to see how much time you spent watching Netflix on your Switch or to see how many hours you’ve logged in Super Smash Bros. Ultimate.

What else is in the Nintendo Store app?

If Play Activity were the only feature in the Nintendo Store app, it would still be worth a download for longtime gamers. However, that’s just a nice-to-have feature, not the main attraction.

The best reason to download the Nintendo Store app is the store itself, which becomes much easier to navigate and search through than the version on the Switch, which can be slow and cumbersome. You can make purchases for your Switch or Switch 2 directly in the app, use Nintendo Points, do GPS check-ins and view events, promotions and game news from the company.

There’s also merchandise available, including game soundtracks, clothing and toys. Being able to quickly navigate which games have demo versions and being able to send a digital download to your Switch from your phone is handy.

An Ask the Developer tab is a nice area to browse in the News section of the app; recent stories discuss the making of Mario Kart World and Donkey Kong Bananza.

Using the Nintendo Store app requires linking your Nintendo account.
