Dazzling Milky Way panorama reveals nearly 1,000 mysterious galactic threads

An astrophysicist behind the beauty compares the image with modern art.

In the early 1980s, scientists imaged the center of our galaxy 25,000 light-years from Earth. To their surprise, they stumbled upon a cluster of «strands» 150 light-years long hanging out in an oddly organized pattern. For years, they scrutinized the stringy forces, trying to understand what they are and why they’re there.

No, these galactic noodles (probably) aren’t the work of aliens. But they later revealed themselves to be some sort of magnetic wiring, catching space-borne cosmic ray electrons and forcing the particles to gyrate around their fields at nearly the speed of light. If anything, the enigma escalated.

Fast-forward to today. The same researcher who led the first imaging endeavor decided to create an updated version. In a paper published online Wednesday and accepted to The Astrophysical Journal Letters, he presents his results: an absolutely spectacular panorama of radio emission data stemming from the Milky Way’s center.

Cosmic phenomena such as star bursts, stellar nurseries and supernova graveyards stained the picture with brilliant streaks, but most strikingly, the image unveiled 10 times more perplexing strands than before. «It’s like modern art,» Farhad Yusef-Zadeh, an astrophysicist at Northwestern University and lead author of the paper, said in a statement. «These images are so beautiful and rich, and the mystery of it all makes it even more interesting.»

He calls the newer picture a «watershed in furthering our understanding of these structures,» because the initial, relatively sparser collection of filaments was too small to draw any real conclusions about their origin and purpose.

Photographing a massive galaxy

It took three years of surveying the sky and 200 hours using the Meerkat telescope at the South African Radio Astronomy Observatory for Yusef-Zadeh’s team to generate precise observations of 20 separate sections.

Then, the researchers pieced the cutouts together and isolated the magnetic filaments by removing the background. That led to the mesmerizing mosaic photograph that resembles a Jackson Pollock.

«I’ve spent a lot of time looking at this image in the process of working on it, and I never get tired of it,» Ian Heywood, an astrophysicist at Oxford University and study co-author, said in a statement. «When I show this image to people who might be new to radio astronomy, or otherwise unfamiliar with it, I always try to emphasize that radio imaging hasn’t always been this way, and what a leap forward Meerkat really is in terms of its capabilities.»

Leads on the filaments

Now blessed with an ocean of inexplicable Milky Way filaments to analyze, Yusef-Zadeh and team are carrying out a sort of population analysis to understand what the cosmic spaghetti strands have in common, and where they differ.

«If you were from another planet, for example, and you encountered one very tall person on Earth, you might assume all people are tall. But if you do statistics across a population of people, you can find the average height,» he said. «That’s exactly what we’re doing. We can find the strength of magnetic fields, their lengths, their orientations and the spectrum of radiation.»

So far, the team concludes the strands’ magnetic fields are amplified as you travel across them and exhibit variation in their radio emissions. Due to the latter, they say the pieces could’ve originated from a black hole that once lurked in the center of our galaxy or a giant radio-emitting bubble, like one discovered in 2019.

Still, huge question marks remain, such as why are these filaments so structured? And why are there so many? Perhaps the biggest confusion lies within the fact that particles on the strands’ field are moving at nearly the speed of light. Any faster, and they’d fit a time-travel requirement.

«How do you accelerate electrons at close to the speed of light?» Yusef-Zadeh wonders. «One idea is there are some sources at the end of these filaments that are accelerating these particles.»

Going forward, the team says they’ll continue searching for answers.

«We’re certainly one step closer to a fuller understanding,» Yusef-Zadeh said. «But science is a series of progress on different levels. We’re hoping to get to the bottom of it, but more observations and theoretical analyses are needed. A full understanding of complex objects takes time.»

Major Amazon Prime Benefit Faces Crackdown Next Month

Amazon plans to end its Prime Invitee program soon. Here’s how this could affect your deliveries.

If you’re using a friend or family member’s free Prime shipping and you don’t live in the same household, you might need to pay another monthly cost. According to Amazon’s updated customer service page, first reported by The Verge, the retail giant is ending its Prime Invitee benefit-sharing program on Oct. 1.

Amazon isn’t the first company to prevent membership sharing between family and friends. The e-commerce giant is just the latest to follow Netflix’s account-sharing crackdown. We also saw it done with Disney-Plus last year. While it’s unclear whether this change will work for Amazon, Netflix gained over 200,000 subscribers following its policy change.

Amazon’s Prime Invitee program is being replaced by Amazon Family, which includes many of the same benefits. However, Amazon Family only works for up to two adults and four children living in the same «primary residential address» — a shared home. While you’ll still be able to use free shipping to send gifts elsewhere, your Prime Invitees will no longer be able to use the perk.

What this means for you

If you’re the beneficiary of someone else’s Prime Invitee benefits, you have one more month to take advantage of the current program before the changes take effect.

Starting in October, you’ll have to get your own Amazon Prime subscription in order to benefit from the company’s free shipping program. First-time subscribers get a year of Prime membership for $15, but you’ll be stuck shelling out $15 a month to maintain your subscription thereafter.

Why is Amazon ending the Prime Invitee program?

This move follows shortly after Reuters reported that Amazon’s Prime account signups slowed down recently despite an extended July Prime Day event. While the company reported blowout sales numbers, new Prime subscriptions didn’t meet internal expectations. In the US, they fell short of last year’s signup metrics.

According to Reuters, Amazon registered 5.4 million US signups over the 21-day run-up to the Prime Day event, around 116,000 fewer than during the same period in 2024, and 106,000 below the company’s own goal, a roughly 2% decline in both metrics.

By forcing separate households to have their own subscriptions, Amazon could be looking to attract more Prime accounts after previously failing to do so.

The new Amazon Family program (previously known as Amazon Household) offers Prime benefits to up to two adults and four children in a single home, including free shipping, Prime Video, Prime Reading, Amazon Music and more. The subscription also includes benefits for certain third-party companies, such as GrubHub.

Premiere Pro for Free: How Adobe’s New iPhone App Will Let You Edit Videos at No Cost

Adobe Premiere users will only have to pay for extra AI credits and cloud storage.

Thanks to social media apps like TikTok and Instagram, everyone is an video editor these days. And soon you won’t have to sit down at a laptop to use one of the most popular video editors on the market.

Adobe announced on Thursday that it is releasing a new video editing iPhone app named Premiere on Sept. 30. You can preorder the app now in the Apple App Store, with an Android app currently in development.

The iOS app should feel familiar to Premiere users, with its multitrack timeline and preview screen. The app can be used for all your usual video editing: trimming clips, overlaying audio and adding synchronized captions. You can also use Adobe’s new voice-to-sound effects tool and record voiceovers.

Premiere should be a big upgrade for Adobe users who have only used Premiere Rush, a barebones version of its video editor. As more content creators become mobile-first, Adobe is hoping to draw them in with revamped mobile apps.

You should be able to use the Premiere iOS app for free. Adobe says you may need to pay for generative AI credits and additional storage, like through Adobe Creative Cloud, though more pricing info is expected closer to the Sept. 30 launch. This is very different from the desktop app, which starts at $23 per month.

A truly free Premiere mobile app would be a win for content creators, especially for anyone who wants to explore editing in Premiere but doesn’t want to pay for another subscription.

In an era of mobile-first content creators, tech companies have raced to introduce user-friendly mobile editing apps. TikTok creators use the ever-popular CapCut, with Meta adding its own contribution, a new app called Edits. Adobe has long been the industry standard for professional content creation and editing, but its mobile offerings were usually less feature-packed versions of its flagship programs under different names.

That changed this year as Adobe released true mobile versions of Photoshop and Firefly AI. The new Premiere app helps Adobe make a competitive entrance in a crowded market, in addition to giving loyal Adobe users a new way to access their tools on the go.

Adobe has also been focused on integrating generative AI into its software. Premiere Pro got its first-ever AI tool, generative extend, which uses AI to add a few extra seconds to clips you upload. It’s meant to help smooth transitions between clips, particularly when you might have turned off the recording a smidge too early and need a few extra seconds of film.

AI is a contentious issue among creators, with some voicing concerns over the training and deployment of AI models. Adobe’s Firefly AI has been fully integrated into the new Premiere iOS app, though the company’s AI guidelines state that it never trains on customer data and that its AI-generated content is commercially safe.
