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.

Adaptive Power in iOS 26 Is Boosting Your iPhone Battery in the Background

We all want more battery life in our phones, and a semi-hidden AI setting in the latest iPhone system is helping to achieve that.

Other Apple Intelligence features get all the attention, but in iOS 26 one of my favorite tools does its thing quietly in the background. On iPhone models that are capable of running Apple’s AI tech, the Adaptive Power setting is at work behind the scenes to extend battery power, even on many older iPhones.

Currently, the iPhone uses as much power as it needs to perform its tasks. You can extend battery life by taking a few simple steps, such as reducing screen brightness and disabling the always-on display. Or, if your battery is running low, you can turn on Low Power Mode, which limits background activity, like fetching mail and downloading data, and dims the screen to help extend battery life. Low Power Mode also kicks in automatically when the battery level reaches 20%.

If Low Power Mode is the hammer that knocks down power consumption, Adaptive Power is the scalpel that intelligently trims energy savings here and there as needed. Based on Apple’s description that accompanies the control, the savings will be felt mostly in power-hungry situations such as recording videos, editing photos or even playing games.

Apple says Adaptive Power takes about a week to analyze your usage behavior before it begins actively working. And it works in the background without needing any management on your part.

Here’s how Apple describes it in the iPhone user guide: «It uses on-device intelligence to predict when you’ll need extra battery power based on your recent usage patterns, then makes performance adjustments to help your battery last longer.»

Which iPhone models can use Adaptive Power?

The feature uses AI to monitor and choose when its power-saving measures should be activated, which means only phones compatible with Apple Intelligence get the feature. These are the models that have the option:

• iPhone 17
• iPhone 17 Pro and iPhone 17 Pro Max
• iPhone Air
• iPhone 16 and iPhone 16 Plus
• iPhone 16 Pro and iPhone 16 Pro Max
• iPhone 16e
• iPhone 15 Pro and iPhone 15 Pro Max

Although some iPad and Mac models support Apple Intelligence, the feature is only available on iPhones.

How to turn Adaptive Power on

Adaptive Power is on by default on the iPhone 17, iPhone 17 Pro, iPhone 17 Pro Max and iPhone Air. For other models, you must opt in to use it. In iOS 26, you’ll find the Adaptive Power toggle in Settings > Battery > Power Mode. To be alerted when the feature is active, turn on the Adaptive Power Notifications option.

Adaptive Power sounds like an outgrowth of Gaming Mode, introduced in iOS 18, which routes all available processing and graphics power to the frontmost app and pauses other processes in order to deliver the best experience possible — at the notable expense of battery life.

What does this mean for your charging habits?

Although we all want as much battery life as possible all the time, judging by the description, it sounds as if Adaptive Power’s optimizations will not always be active, even if you leave the feature on. «When your battery usage is higher than usual» could include a limited number of situations. Still, considering that according to a CNET survey, 61% of people upgrade their phones because of battery life, a feature such as Adaptive Power could extend the longevity of their phones just by updating to iOS 26.

I also wonder whether slightly adjusting display brightness could be disruptive, but in my experience so far, it hasn’t been noticeable. Because the feature also selectively de-prioritizes processing tasks, the outward effects seem minimal. When it’s activated on my iPhone 16 Pro, the only indication was the Adaptive Power alert that appeared.

We’ll get a better idea about how well Adaptive Power works as more people adopt iOS 26 and start buying new iPhone models. Also, remember that shortly after installing a major software update, it’s common to experience worse battery life as the system optimizes data in the background; Apple went so far as to remind customers that it’s a temporary side effect.

Black Ops 7 Double XP Weekend and Free Trial Are Live Now

Whether you already own Black Ops 7 or you’re taking advantage of the free weekend, level up your account twice as fast during this double XP weekend.

Call of Duty: Black Ops 7 developer Treyarch is letting new players try the game for free this weekend with a new multiplayer free trial. Even if you haven’t bought Black Ops 7, you can try out the game’s Zombies and Multiplayer modes during this time. If you’re already knee-deep in the latest Call of Duty game, there’s still something to get excited over — a double XP weekend is running in tandem with the free weekend, letting you level up twice as fast as you cut down new and returning players.

The latest double XP weekend is live now, featuring a sole double account level XP boost this time around. This double XP weekend runs from Thursday, Feb. 5, to Monday, Feb. 9. Anyone playing Black Ops 7 during the event period has a universal double account XP earn rate applied to their account. If you log in now, you can hop into battle and reap the rewards of this double XP weekend right away.

Unlike other double XP weekends, this event doesn’t feature the Quad Feed boost. That means players won’t be able to benefit from all four customary double XP weekend boosts at the same time. Your double XP tokens will also be locked for the duration of the event.

Here’s everything you need to know about this double XP weekend. If you’re looking for something else to play, see our recommendations for the best game subscription services.

When does the double XP weekend start in Call of Duty: Black Ops 7?

This double XP weekend kicked off Thursday at 1 p.m. ET and is live now.

ET: Feb. 5 at 1 p.m.
CT: Feb. 5 at noon.
MT: Feb. 5 at 11 a.m.
PT: Feb. 5 at 10 a.m.

It’s always worth starting your game before your gaming session, if possible. As with every Black Ops 7 patch, the update will require you to download new content and restart the application.

When does the double XP weekend end in Call of Duty: Black Ops 7?

Some double XP «weekends» are much longer events, lasting five to seven days. The current double XP weekend isn’t nearly that long. This double XP weekend will end on Monday. Your double XP tokens will once again unlock after this time.

Here’s when the double XP weekend will end in your time zone:

ET: Feb. 9 at 1 p.m.

PT: Feb. 9 at 10 a.m.

Does Call of Duty Warzone have double XP this weekend?

New players have a chance to level up the weapons they unlock from the new and improved Warzone Armory, and returning players can continue unlocking new attachments for the suite of Black Ops 7 weaponry added to Warzone.
