NASA captures violent flash from sun’s mini eruption

Check out this beautiful image of our very own star’s minor tantrum.

On Thursday, our sun released its pent-up energy in the form of a little magnetic bomb. It’s called a solar flare, and NASA caught the whole thing on camera.

Solar flares, which are sudden explosions on the sun’s surface caused by strong magnetic forces, are of concern to astronomers because these events can impact electrical power grids on Earth, causing regional blackouts. They also risk interference with radio communications.

«This event, in particular, disrupted radio communications over the Indian and Pacific oceans — so its likely biggest impact was a disruption of maritime communications,» said Jesse Woodroffe, a program scientist and expert in space weather at NASA.

Even more jarring is if astronauts are in the flares’ line of fire, such detonations may greatly threaten space traveler and spacecraft safety. The good news, though, is NASA categorized the recent flare as a category M5.5 midlevel eruption, which corresponds to both a moderate severity and radio blackout threat for the side of the planet facing the burst.

«It’s not exceptionally strong in the grand scheme of things,» Woodroffe said, «but it nevertheless can have significant effects depending on what portion of the Earth is sunlit at the time of the flare.»

For now we can just sit back and admire the spectacular image captured by the agency in «extreme ultraviolet light,» colorized in an absolutely mesmerizing teal blue.

Around 300 M-class flares occur during each solar cycle, and they’re most likely to occur near solar maximum, a point we’re steadily approaching, according to Woodroffe. «Right now this is shaping up to be a much more active and interesting solar cycle than the last one. That means that we could be in store for solar activity the likes of which we haven’t seen in nearly 20 years.»

What causes a solar flare?

Instead of a glowing orb, think of the sun as a giant, flaming, spherical ocean. This ocean is so ridiculously hot, at 5,778 Kelvin (9940.73 Fahrenheit), that would-be atoms on the star are completely blasted apart into a gaseous mixture of ions and electrons called a plasma.

These particles, with varying positive and negative charges, work together to form the sun’s magnetic field lines, thereby deciding how the boiling ocean moves around. Think of it as a sort of immensely strong, magnetic soup — more precisely, picture a chicken noodle soup. The noodles are the sun’s magnetic fields.

However, just as stirring your soup in search of a baby carrot can tangle your noodles, these charged-up, magnetic lines can grow tangled, most often near sunspots. Eventually, as regions of the spaghetti-like magnetic fields form complex knots and push and pull on each other, they experience an energy overload.

That forces them to explode into space, revealing a fiery loop on the side of our enormous star, called a solar flare.

«There is also a potential for solar flares to cluster, meaning the occurrence of one could presage the appearance of more, potentially stronger flares,» Woodroffe said. «Thus, monitoring for events such as this is important because it could be the precursor of something more serious.»

And sometimes, the fiery loop stretches out until it becomes taut enough to sort of snap off, resulting in a coronal mass ejection. «A coronal mass ejection is, in essence, a little bit of the sun that gets blown off and sent flying into space towards Earth,» Woodroffe said.

Once it snaps off, the ejected portion heads directly toward our planet, picking up space-borne particles along the way and causing what’s called a solar storm. Thankfully, Earth’s atmosphere protects us from the brunt of the charged particles, with only relatively few getting caught in our planet’s shield. When that happens, though, we look up at these trapped, zippy particles in awe.

They appear to us as the Northern Lights.

«I don’t know if there was a coronal mass ejection associated with this flare, but we are expecting the possible arrival of a coronal mass ejection associated with a flare that occurred on Jan. 18,» Woodroffe said. «So, even if it’s not because of this flare, we could very well see some nice auroras this weekend.»

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.
