Why the Ghost Particles Crashing Into Antarctica Could Change Astronomy Forever

About 1.2 miles beneath Antarctica, an underground observatory is hunting for «ghost particles.» What it finds could reveal the unseen heart of a distant galaxy.

About 47 million light-years from where you’re sitting, the center of a black-hole-laden galaxy named NGC 1068 spits out streams of enigmatic particles. They’re neutrinos — otherwise known as the elusive «ghost particles» haunting our universe while leaving little trace of their existence.

Immediately after coming into being, bundles of these invisible bits plunge across the cosmic expanse. They whisk by bright stars we can see and zip past pockets of space teeming with marvels we’re yet to discover. They fly and fly and fly until, occasionally, they reach Earth’s South Pole and drill themselves underground. The neutrinos’ journey is seamless.

But scientists patiently wait for them to arrive.

Nestled into about 1 billion tons of ice, more than 2 kilometers (1.24 miles) beneath Antarctica, lies the IceCube Neutrino Observatory. A neutrino hunter, you might call it. And when any neutrinos transfer their party to the frigid continent, IceCube remains vigilant.

In a paper published Friday in the journal Science, the international team behind this ambitious experiment confirmed it has found evidence of 79 «high-energy neutrino emissions» coming from around where NGC 1068 is located, opening the door for novel — and endlessly fascinating — types of physics. «Neutrino astronomy,» scientists call it.

It’d be a branch of astronomy that can do what existing branches simply cannot.

Before today, physicists had only shown neutrinos coming from either the sun; our planet’s atmosphere; a chemical mechanism called radioactive decay; supernovas; and — thanks to IceCube’s first breakthrough in 2017 — a blazar, or voracious supermassive black hole pointed directly toward Earth. A void dubbed TXS 0506+056.

With this newfound neutrino source, we’re entering a new era of the particle’s story. In fact, according to the research team, it’s likely neutrinos stemming from NGC 1068 have up to millions, billions, maybe even trillions the amount of energy held by neutrinos rooted in the sun or supernovas. Those are jaw-dropping figures because, in general, such ghostly bits are so powerful, yet evasive, that every second, trillions upon trillions of neutrinos move right through your body. You just can’t tell.

And if you wanted to stop a neutrino in its tracks, you’d need to fight it with a block of lead one light-year-wide — though even then, there’d be a fractional chance of success. Thus, harnessing these particles, NCG 1068’s version or not, could allow us to penetrate areas of the cosmos that’d usually lie out of reach.

Now what?

Not only is this moment massive because it gives us more proof of a strange particle that wasn’t even announced to exist until 1956, but also because neutrinos are like keys to our universe’s backstage.

They hold the capacity to reveal phenomena and solve puzzles we’re unable to address by any other means, which is the primary reason scientists are trying to develop neutrino astronomy in the first place.

«The universe has multiple ways of communicating with us,» Denise Caldwell of the National Science Foundation and a member of the IceCube team, told reporters on Thursday. «Electromagnetic radiation, which we see as light from stars, gravitational waves that shake the fabric of space — and elementary particles, such as protons, neutrons and electrons spewed out by localized sources.

«One of these elementary particles has been neutrinos that permeate the universe, but unfortunately, neutrinos are very difficult to detect.»

In fact, even the galaxy NGC 1068 and its gargantuan black hole are typically obscured by a thick veil of dust and gas, making them hard to parse with standard optical telescopes and equipment — despite years of scientists trying to pierce its curtain. NASA’s James Webb Space Telescope could have a leg up in this case due to its infrared eyes, but neutrinos may be an even better way in.

Expected to be generated behind such opaque screens filtering our universe, these particles can carry cosmic information from behind those screens, zoom across great distances while interacting with essentially no other matter, and deliver pristine, untouched information to humanity about elusive corners of outer space.

«We are very lucky, in a sense, because we can access an amazing understanding of this object,» Elisa Resconi, of the Technical University of Munich and IceCube team member, said of NGC 1068.

It’s also notable that there are many (many) more galaxies similar to NGC 1068 — categorized as Seyfert galaxies — than there are blazars similar to TXS 0506+056. This means IceCube’s latest discovery is, arguably, a larger step forward for neutrino astronomers than the observatory’s seminal one.

Perhaps the bulk of neutrinos diffusing throughout the universe are rooted in NGC 1068 doppelgangers. But in the grand scheme of things, there’s far more to the merit of neutrinos than just their sources.

These ghosts, as Justin Vandenbroucke of the University of Wisconsin-Madison and an IceCube team member put it, are fit to solve two major mysteries in astronomy.

First off, a wealth of galaxies in our universe boast gravitationally monstrous voids at their centers, black holes reaching masses millions to billions of times greater than our sun’s. And these black holes, when active, blast jets of light from their guts — emitting enough illumination to outshine every single star in the galaxy itself. «We don’t understand how that happens,» Vandenbrouke said simply. Neutrinos could provide a way to study the regions around black holes.

Second is the general, yet persistent, conundrum of cosmic rays.

We don’t really know where cosmic rays come from either, but these strings of particles reach energies to and beyond millions of times higher than we can reach here on Earth with human-constructed particle accelerators like the one at CERN.

«We think neutrinos have some role to play,» Vandenbroucke said. «Something that can help us answer these two mysteries of black holes powering very bright galaxies and of the origins of cosmic rays.»

A decade to catch a handful

To be clear, IceCube doesn’t exactly trap neutrinos.

Basically, this observatory tells us every time a neutrino happens to interact with the ice shrouding it. «Neutrinos hardly interact with matter,» Vandenbrouke emphasized. «But they do interact sometimes.»

As millions of neutrinos shoot into the icy region where IceCube is set up, at least one tends to bump into a speck of ice, which then shatters and produces a flash of light. IceCube sensors capture that flash and send the signal up to the surface, notifications that are then analyzed by hundreds of scientists.

Ten years of light-flash-data allowed the team to pretty much map out where every neutrino seems to be coming from in the sky. It soon became clear there was a dense region of neutrino emissions located right where galaxy NGC 1068 is stationed.

But even with such evidence, Resconi said the team knew «it’s not the time to open the champagne, because we still have one fundamental question to answer. How many times did this alignment happen just by chance? How can we be sure neutrinos are actually coming from such an object?»

So, to make matters as concrete as possible, and really, truly prove this galaxy is spitting out ghosts, «we generated 500 million times the same experiment,» Resconi said.

Upon which, I can only imagine, a bottle of Veuve was popped at last. Though the hunt isn’t over.

«We are only beginning to scratch the surface as far as finding new sources of neutrinos,» Ignacio Taboada of the Georgia Institute of Technology and IceCube team member said. «There must be many other sources far deeper than NGC 1068, hiding somewhere to be found.»

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.

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

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.
