Scorching exoplanet is a little like Earth in one key way, scientists say

Our planet has a few talking points to go over with its (very) distant cosmic relative.

Approximately 322 light-years from Earth, an extreme planet by the name of WASP-189b orbits one of the hottest stars in the universe, HD 133112.

Twenty times closer to its star than we are to the sun, WASP-189b absolutely blisters with a daytime temperature of 5,792 degrees Fahrenheit (3,200 degrees Celsius). The scorching exoplanet is also made of gas and about 1.5 times the size of Jupiter — something like 1,950 Earths could fit inside it.

Needless to say, since its discovery in 2018, scientists very understandably reasoned that WASP-189b isn’t anything like our home orb. But in a paper published Thursday in the journal Nature Astronomy, a team of researchers found a way for Earth to relate to its distant cosmic relative. The two could chitchat about their layered atmospheres, and Earth could gossip about its ozone holes and climate change.

Here on Earth, we have an atmospheric layer called the troposphere that starts at sea level and that holds a ton of water vapor. Clouds, and therefore weather such as rain and snow, originate there. Above that, we have the stratosphere, home to the ozone layer, which protects us from the sun’s ultraviolet radiation.

«In the past, astronomers often assumed that the atmospheres of exoplanets exist as a uniform layer and try to understand it as such,» Jens Hoeijmakers, an astrophysicist at Lund University and study co-author, said in a statement.

However, upon analyzing WASP-189b by measuring starlight passing through the atmosphere of the intensely heated exoplanet — with the HARPS spectrograph at the La Silla Observatory in Chile — Hoeijmakers and fellow researchers found a unique chemical signature to shake up our knowledge of planetary atmospheres. It indicated that the distant orb’s atmosphere may have layers like Earth’s.

«The gases in its atmosphere absorb some of the starlight, similar to ozone absorbing some of the sunlight in Earth’s atmosphere, and thereby leave their characteristic ‘fingerprint,'» Bibiana Prinoth, an astrophysicist at Lund University and lead author of the study, said in a statement.

Baking away, WASP-189b emitted signals of iron, chromium, vanadium, magnesium and manganese. But most importantly, Prinoth says, «in our analysis, we saw that the ‘fingerprints’ of the different gases were slightly altered compared to our expectation. We believe that strong winds and other processes could generate these alterations.»

Those adjustments varied across the range of elements detected, similarly to the way Earth’s water vapor and ozone are affected differently by natural processes due to atmospheric layering. Voila — that hints at the existence of layers on WASP-189b, too.

But wait, there’s more. The team also uncovered remnants of titanium oxide in WASP-189b’s atmospheric shield. «Titanium oxide absorbs shortwave radiation, such as ultraviolet radiation,» Kevin Heng, an astrophysicist at the University of Bern and study co-author, said in a statement. «Its detection could therefore indicate a layer in the atmosphere of WASP-189b that interacts with the stellar irradiation similarly to how the ozone layer does on Earth.»

So WASP-189b might have its own ozone layer.

«Our results demonstrate that even the atmospheres of intensely irradiated giant gas planets have complex three-dimensional structures,» Hoeijmakers said, addressing how the new paper’s outcomes could dictate the way exoplanet atmospheres are scrutinized in the future.

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.
