Violent solar storm produces dazzling, swirling aurora captured on camera

The sun delivered an ethereal aurora to the planet after a solar outburst earlier this month.

Earlier this month, the sun spit out what the European Space Agency described as a «violent mass of fast-moving plasma» known as a coronal mass ejection. These CMEs can disrupt communications and GPS systems but can also deliver outstanding auroras on Earth. ESA has released an eye-catching video of one of the glowing lightshows that followed the Oct. 9 coronal mass ejection.

«What I love about this video is the chance to see this beautiful, purple aurora, more clearly visible during intense geomagnetic storms,» space weather applications scientistHannah Laurens said in an ESA statement last week.

The video is from the fish-eye point of view of an all-sky camera in Kiruna, Sweden, that faces up to see the sky from horizon to horizon. The camera, part of ESA’s Space Weather Service Network, observed the aurora on Oct. 12. The video feels like watching a magic crystal ball as the aurora swishes from green to purple.

The green colors are «created when energetic particles in the solar wind collide with oxygen in Earth’s atmosphere,» ESA said. The rarer purple colors come from the charged particles interacting with nitrogen. It’s a fantastical lab experiment in the sky — with real-life implications.

«While humans on Earth are protected by Earth’s magnetic field,» ESA said, «space weather can have an extreme and disruptive impact on satellites in orbit and infrastructure on Earth, and ultimately our society.»

Laurens noted that studying the swirling movement of the aurora helps scientists monitor space weather conditions.

The all-sky camera’s video is for serious scientific study, but it’s also worth a few moments of marveling at the connections between the moods of the sun and life on this planet.

WeTransfer Backtracks on AI File Training After Backlash: What You Need to Know

The company has updated the changes to its policies after some users objected to new terms.

WeTransfer, the service that allows users to send large files to others, is explaining itself to clients and updating its terms of service after a backlash related to training AI models.

The company published a blog post, «WeTransfer Terms of Service — What’s Really Changing,» that details more updates the company made to its policies, after users noticed that recent changes seemed to suggest WeTransfer was training AI models on the files users are transferring.

In the blog post, the company says: «First things first. Your content is always your content.»

The post goes on to say, «We don’t use machine learning or any form of AI to process content shared via WeTransfer.» WeTransfer explains that its use of AI would be to improve content moderation and enhance its ability to prevent the distribution of harmful content across its platform.

The company adds that those AI tools aren’t being used and haven’t been built yet. «To avoid confusion,» it says, «we’ve removed this reference.» 

A representative for WeTransfer did not immediately return an email seeking further comment.

The backlash over the terms prompted users such as political correspondent Ava Santina to write on X, «Time to stop using WeTransfer who from 8th August have decided they’ll own anything you transfer to power AI.» 

What this means for users

Anxieties are high about what information users share or store in services such as social media accounts is accessed by companies to train AI models. WeTransfer may be used for highly sensitive file transfers, raising fears that private information might be accessed by AI. According to the company, this isn’t the case.

To further explain, the company said in its post:

  • «YES — Your content is always your content. In fact, section 6.2 of our Terms of Service clearly states that you ‘own and retain all right, title, and interest, including all intellectual property rights, in and to the Content’.»
  • «YES — You’re granting us permission to ensure we can run and improve the WeTransfer service properly.»
  • «YES — Our terms are compliant with applicable privacy laws, including the GDPR.»
  • «NO — We are not using your content to train AI models.»
  • «NO — We do not sell your content to third parties.»

When the Terms of Service change

While eagle-eyed experts understood the potential implications of what WeTransfer’s new terms could mean for people using the service, it’s unlikely that most people would be able to spot such changes.

«Expecting users to fully understand Terms of Service is unrealistic. These documents are often too complex to navigate,» says Haibing Lu, associate professor at the Leavey School of Business at Santa Clara University. 

Lu told CNET that companies would do well to clearly highlight any changes they make to AI-related terms and explain them clearly to give people a real choice. «That’s what true transparency looks like,» Lu says. «Companies are increasingly risking backlash when they update Terms of Service to include AI, especially when users’ data is involved.»

Companies including Adobe, Slack and Zoom have had similar issues with terms changes related to AI, but it’s not just AI that’s the problem, Lu says — rather, it’s the lack of transparent communication.

In the case of WeTransfer, Lu says the company’s response, including revising the terms and blogging about them, «was a smart move and helped rebuild trust. It showed they were listening and willing to act fast.»

WeTransfer could include more understandable language in its terms, or communicate the changes better or sooner, Lu says, adding: «Transparency shouldn’t start after a backlash.»
