Rare binary star, spotted for the first time, answers a long-standing question

This breakthrough could fill a gap in the stellar evolutionary timeline.

The universe is a star museum. Up close, we have our beloved sun in its middle age. Farther out, we’ll find white dwarfs nearing the end of their days. Peer deeper, and you’ll stumble upon hyper-dense neutron stars on the brink of turning into black holes. Now, for the first time, scientists have uncovered a star exhibit that, for years, has only been a hypothesis.

Technically, the team’s discovery is of a binary star system, or one star orbiting another. In this case, the smaller companion is eating the larger star, and very soon, the sparkly orb being chomped on will become a rare form of white dwarf, or late-stage star, called an extremely low mass, or ELM, white dwarf.

They’ve published a paper explaining their findings in this month’s issue of Monthly Notices of the Royal Astronomical Society.

Though fascinating in itself, the sighting of the deteriorating binary star could also fill an empty slot in a long-standing cosmic puzzle.

«This is exciting; it’s a missing evolutionary link in binary star formation models that we’ve been looking for,» Kareem El-Badry, lead author of the paper and a researcher from the Institute for Theory and Computation at the Harvard-Smithsonian Center for Astrophysics, said in a statement.

Zooming out from the binary star itself, El-Badry’s discovery fills a gap in our knowledge of how ELM white dwarfs are generated in the first place. We know ELM white dwarfs exist, as scientists have already pinpointed them, but these stellar bodies pose a conundrum.

According to astronomical calculations, experts say, for a star to naturally reach the mass of an ELM white dwarf, it would need to have been born over 13.8 billion years ago. The issue is, the universe itself is only 13.8 billion years old — so that doesn’t really make sense with what we know about the cosmos so far.

Therefore, the only way these stars could possibly be formed within the universe’s timeline is if an external force created them. That force, theorists say, could be the gravitational pull of a companion in a binary star system that’s pulling matter away from the other until the latter object becomes an ELM white dwarf. Seems intuitive, but for a long time, that was just a hypothesis.

Scientists have come upon binary star systems called cataclysmic variables where regular, massive stars are being consumed by a companion star. They’ve even recorded ELM white dwarfs with companions no longer consuming them. It’s easy to extrapolate that an intermediate step would involve an almost-ELM white dwarf with a companion star eating away at it, but no one had seen such a sight.

Thanks to El-Badry’s revelatory documentation, the transitional step appears to be proven at last.

Star hunting

El-Badry used a wide array of star data, several astronomical surveys and his own firsthand observations with the Shane Telescope at the Lick Observatory in California to locate the unique binary star. He’d come up with 50 potential candidates of transitional ELM white dwarfs and ultimately zeroed in on 21 options.

«100 percent of the candidates were these pre-ELMs we’d been looking for,» he explained in the statement. «They were more puffed up and bloated than ELMs. They also were egg-shaped because the gravitational pull of the other star distorts their spherical shape.»

Aptly, he compares the importance of this breakthrough to biological studies of organisms. «You go out into the jungle and find an organism. You describe how big it is, how much it weighs — and then you go on to some other organism,» he said. «You see all these different types of objects and need to piece together how they are all connected.»

Like the ever-advancing tree of life, El-Badry’s new evidence of ELM white dwarfs helps to unveil the entirety of our cosmic star gallery. «We found the evolutionary link between two classes of binary stars — cataclysmic variables and ELM white dwarfs — and we found a decent number of them,» he said.

Next, he hopes to delve into the other 29 pre-ELM white dwarf star candidates to enrich the universe’s star museum even further.

Stay Informed About Your Flights This Holiday Season With Your iPhone’s Tracker

Your iPhone is hiding a flight tracker. Here’s how it works.

Thanksgiving is only a few short weeks away and if you plan on flying during the holiday season, keeping up-to-date on changes to your flights is crucial. Airports can be hectic during any holiday, but with the government shutdown continuing, flights are liable to change or be cancelled more often.

Luckily, it’s never been easier to get up-to-date information about your flight. For starters, your airline probably has an app, and if not, you can check its website. If you’re in a hurry, you can Google the flight number. Or you can just use your iPhone’s built-in flight tracker that’s sneakily tucked away.

That’s right: Your iPhone has a flight tracker that you may have never known about. It’s there for when it’s needed. Below, we’ll show you have to access it in not one, but two places, so you never have to go hunting for your flight info elsewhere again.

Don’t miss any of our unbiased tech content and lab-based reviews. Add CNET as a preferred Google source on Chrome.

For more on the iPhone, check out everything Apple announced at WWDC 2025.

How to track your flight via iMessage

Before we start, there are a few prerequisites you must meet:

Make sure iMessage is enabled (it doesn’t work with SMS/MMS).
You’ll need your flight number somewhere in your text messages, whether you’ve sent that information to someone (even yourself) or it’s been sent to you.
The flight number must be sent in this format: [Airline] [Flight number], for example, American Airlines 9707.

Launch the native Messages app on your iPhone and open the text message thread that contains your flight information. You’ll know the flight tracker feature works when the text with the flight information appears underlined, which means it’s actionable and you can tap on it.

If your flight is still several months away or it’s already passed, you might see a message that says, «Flight information unavailable.» You might also see another flight that’s not yours because airlines recycle flight numbers.

You can check your flight status from Spotlight Search, too

If getting your flight information from Messages wasn’t easy enough, you can also grab the details right from your iPhone’s home screen by swiping down and adding your flight number into Spotlight Search. Even better, this works with Spotlight Search on your Mac computer, too.

How to access the hidden flight tracker

Although the airline name/flight number format highlighted above is the best way to go, there are other texting options that will lead you to the same result. So let’s say we stick with American Airlines 9707, other options that may bring up the flight tracker include:

AmericanAirlines9707 (no spaces)
AmericanAirlines 9707 (only one space)
AA9707 (airline name is abbreviated and no space)
AA 9707 (abbreviated and space)

I would suggest you keep the airline name spelled out completely and add a space between the two pieces of information — like in the previous section — because for some airlines, these alternative options may not work.

Real-time flight tracking

Once everything is set, tap on the flight information in your text messages. If the feature works correctly, you should see the following two options appear in a quick-action menu:

Preview Flight: View the flight’s details. Tap this to view more information about the flight.
Copy Flight Code: Copy the flight code to your clipboard (in case you want to send your flight details to someone else via text or email).

If you select Preview Flight, at the top of the window, you’ll see the best part of this feature: a real-time flight tracker map. A line will connect the two destinations, and a tiny airplane will move between them, indicating where the flight is at that exact moment.

Underneath the map, you’ll see important flight information:

Airline name and flight number
Flight status (arriving on time, delayed, canceled, etc.)
Terminal and gate numbers (for arrival and departure)
Arrival and departure time
Flight duration
Baggage claim (the number of the baggage carousel)

If you swipe left on the bottom half of the flight tracker, you can switch between flights, but only if there’s a return flight.

This $20K Humanoid Robot Promises to Tidy Your Home. But There Are Strings Attached

The new Neo robot from 1X is designed to do chores. It’ll need help from you — and from folks behind the curtain.

It stands 5 feet, 6 inches tall, weighs about as much as a golden retriever and costs near the price of a brand-new budget car.

This is Neo, the humanoid robot. It’s billed as a personal assistant you can talk to and eventually rely on to take care of everyday tasks, such as loading the dishwasher and folding laundry.

Neo doesn’t work cheap. It’ll cost you $20,000. And even then, you’ll still have to train this new home bot, and possibly need a remote assist as well.

If that sounds enticing, preorders are now open (for a mere $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, 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 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 in your home.

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 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 for any chore request Neo doesn’t know how to accomplish, «you can schedule a 1X Expert to guide it» 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 let Neo learn from their environment so that future versions can operate more independently.

That learning process raises privacy and trust questions. The robot uses a mix of visual, audio and contextual intelligence — meaning it can see, hear and remember interactions with users throughout their homes.

«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 (formerly Twitter) on Monday.

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 will ship to customers in the US in 2026. There is a $499 monthly subscription alternative to the $20,000 full-purchase price, though that 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.
