Eerie NASA audio lets you hear what Jupiter moon Ganymede sounds like

Is that a dial-up modem or a celestial body?

What does a moon sound like? NASA has an answer thanks to the Juno spacecraft. Juno took a swing by Jupiter’s big moon Ganymede in June. It sent back some stunning visuals, and its Waves instrument also collected data on electric and magnetic radio waves.

NASA took the Waves data and shifted it into an audio range that humans can hear. The result is eerily like something you’d hear from an old-fashioned dial-up modem, or perhaps the soundtrack to some spooky ’80s sci-fi alien movie.

Waves is focused on studying Jupiter’s magnetosphere, the area around the gas giant controlled by its magnetic field. NASA says Jupiter’s magnetosphere «is the largest object in the solar system. If it glowed in wavelengths visible to the eye, it would appear two to three times the size of the sun or moon to viewers on Earth.»

Ganymede — the largest of Jupiter’s 79 known moons — has its own magnetosphere. We might not be able to see these magnetic fields directly, but the audio version of Juno’s experience brings the concept closer to home.

«This soundtrack is just wild enough to make you feel as if you were riding along as Juno sails past Ganymede for the first time in more than two decades,» Juno principal investigator Scott Bolton said in a NASA statement on Friday. «If you listen closely, you can hear the abrupt change to higher frequencies around the midpoint of the recording, which represents entry into a different region in Ganymede’s magnetosphere.»

NASA has a knack for translating data into sound — a process called data sonification — to give us new ways of engaging with space missions. Hear the haunting sounds of black holes and galaxies or listen in on Juno’s approach to Jupiter in 2016.

The not-so-dulcet tones of Ganymede won’t lull you gently to sleep, but they might trigger memories of the internet’s earlier days, when your greatest annoyance was mom picking up the phone while you updated your GeoCities Buffy the Vampire Slayer fansite.

This Two-Faced Watch Band Lets You Hide an Apple Watch Under Your Rolex

The $418 Smartlet literally bridges the gap between your elegant analogy and your nerdy smartwatch.

The Consumer Electronics Show is never short on ambitious ideas, but Smartlet may be one of the more unusual ones this year: a modular watch strap that lets you wear a traditional mechanical watch and a smartwatch on the same wrist, simultaneously. One on top of the other.

The Paris-based startup announced Smartlet at the 2026 CES in Las Vegas, pitching it as a solution for people who love the look of an analog watch but also want the practicality of a smartwatch for notifications, fitness tracking and mobile payments. Instead of choosing between the two, Smartlet’s system lets you mount an old-school timepiece on the front of your wrist while hiding a smartwatch or fitness tracker on the underside.

The stainless steel strap starts at $418 and doesn’t include a smartwatch or a mechanical watch. What you’re really buying is the strap system, which is compatible with most major smartwatches and fitness trackers, including Apple Watch, Samsung Galaxy Watch, Google Pixel Watch, Garmin models, Fitbit Charge devices and Whoop. On the analog side, it supports watches with lug widths from 18 to 24 mm, which includes high-end models from brands such as Omega, Tudor, TAG Heuer and Rolex.

The idea comes from founder David Ohayon, who says he was tired of having to play favorites every morning, choosing between his analog and Apple Watch. Smartlet, in theory, offers the best of both worlds, letting you toggle from fitness nerd to polished executive with the flick of a wrist.

In practice, it raises some serious questions, the biggest one being bulk. Smartlet says the system adds between 9 and 12 mm of height to the underside of the wrist once a connected device is attached. As someone who already manages to scratch watches without trying, the idea of strapping a second device to the underside of my wrist, where it regularly comes in contact with desks, armrests and tabletops, sounds like a walking nightmare.

There’s also the aesthetic. Smartlet is clearly aimed at what it calls the «modern gentleman,» with marketing language that leans heavily into luxury watch culture and phrases like «from the boardroom to the weekend.» Translation: This is a watch for wealthy men who want to show off their investment piece without sacrificing their gym gain tracking.

And while it may not be the most practical, or budget-friendly solution for most people, Smartlet is one of those highly niche, standout products that had us doing a double take at this year’s CES.

LORDS, MAIDS, SWANS, LADIES, PIPERS, DRUMMERS

Today’s Strands spangram

Today’s Strands spangram is CHRISTMASDAYS. To find it, look for the C that’s three letters down on the far-left row, and wind across.
