A ‘Messy’ Star Death: How an Early Muse of NASA’s Webb Telescope Came to Be

The Southern Ring Nebula, brought to you by a star’s explosive demise.

When NASA released the James Webb Space Telescope’s very first images this year, astronomers and space-lovers all over the world were met with a menagerie of blurred galaxies from near the beginning of time, coffee-hued dust clouds brimming with wonderful secrets and incandescent realms fit for Disney princess castles. It was a glorious moment for humankind, witnessing how stars can unite us beneath our layers of division.

But among this trailblazing telescope’s first five images, one especially stood out not only for its beauty but also for its mystery — a striking portrait of the Southern Ring Nebula hid an important history yet to be known. Simply, scientists wanted to learn what, exactly, caused this intricate, amoeba-shaped, ancient star explosion aftermath to exist?

Et, voila.

On Thursday, an international team of nearly 70 astronomers used the JWST’s stunning image to deduce the Southern Ring Nebula’s backstory.

Details are published in the journal Nature Astronomy, but basically, what they found is that some 2,500 years ago, a star nearly three times the size of our sun died at about 500 million years of age.

When it died, they say, the stellar body ejected most of its mass into surrounding space, forming shrouds of gas that slowly expanded with time until they turned into the complex folds we see today in the JWST’s Southern Ring Nebula structure.

Then, when all was said and done, the deceased star left behind a sort of corpse, or white dwarf star, with about half the mass of our sun but around the size of Earth. (That’s super dense, to be clear).

Plus, as an added surprise, the astronomers also found evidence of two or three companion stars they believe hastened the blown up star’s death — as well an «innocent bystander» star that might’ve just gotten caught up in the mix.

«When we first saw the images, we knew we had to do something, we must investigate!» Orsola De Marco, lead author of the paper and astrophysicist at Macquarie University, said in a statement. «The community came together, and from this one image of a randomly chosen nebula, we were able to discern much more precise structures than ever before. The promise of the James Webb Space Telescope is incredible.»

That Southern Ring Nebula image really is something

Even back in July, the JWST’s Southern Ring Nebula rendition had raised eyebrows during its reveal. I mean, at the top left of one version of the JWST’s view, taken with the Mid-Infrared instrument, a weird bluish line ended up literally being a galaxy photobomber.

«I made a bet that said, ‘It’s part of the nebula,'» NASA astronomer Karl Gordon recounted during the unveiling. «I lost the bet, because then we looked more carefully at both Nircam and MIRI images, and it’s very clearly an edge-on galaxy.»

We were also able to see not one but two stars dance around one another at the marvel’s center for the first time, stirring the pot of gas and dust to create the ornate patterns that make the image perfect as an iPhone background. (Yes, one of these is the white dwarf that De Marco and fellow scientists discuss in their latest paper.)

«This star is now small and hot but is surrounded by cool dust,» Joel Kastner, another team member from the Rochester Institute of Technology, said in a statement. «We think all that gas and dust we see thrown all over the place must have come from that one star, but it was tossed in very specific directions by the companion stars.»

The other star visible in the JWST’s photo, according to the team, is just one of the companion stars that orbits the central star while the latter loses mass over time.

However, as to why the team believes there aren’t just two stars at play here but rather three, four – maybe more – that’s because of how a series of spiral structures seem to be moving out from the center, generating arches, and how a 3D view of the nebula’s data points to irregular jets of matter shooting from the phenomenon’s center.

«We first inferred the presence of a close companion because of the dusty disk around the central star, the further partner that created the arches and the super far companion that you can see in the image,» De Marco said. «Once we saw the jets, we knew there had to be another star or even two involved at the center, so we believe there are one or two very close companions, an additional one at middle distance and one very far away.

«If this is the case, there are four or even five objects involved in this messy death.»

Speediance’s Compact Resistance Trainer and Wearable Make Wellness and Fitness More Connected

Speediance unveils a portable strength training device and a wearable at CES.

Speediance unveiled its new Gym Nano and Speediance Strap products this week at CES 2026. The smart fitness equipment manufacturer, which previously developed its own smart home gym, the Gym Monster 2, designed the Gym Nano and Speediance Strap to complement its current equipment ecosystem.

«Rather than developing products in isolation, we’re building a comprehensive training and health ecosystem that adapts to users’ real lives and empowers better decision-making over time,» Speediance founder and CEO Liu Tao said in a statement.

Speediance used the consumer tech expo in Las Vegas to demonstrate the Gym Nano, a portable, motor-driven cable resistance training system designed to occupy minimal space for those who prefer to work out at home. The strap is a prototype wearable device designed to read your health data and provide training recommendations based on this insight.

CNET previously tested Speediance’s VeloNix AI Smart Bike and named it the best AI-powered exercise bike.

Gym Nano

The Gym Nano is a compact digital cable resistance machine trainer that fits any space and delivers full-body workouts. It’s meant to make strength training at home easier if you have limited space and can’t commit to larger home gym equipment.

The Gym Nano offers up to 220 pounds of resistance through adjustable 1-pound increments. It also has five dynamic weight modes: Eccentric, Chain, Standard, Fixed Speed and Sled.

Speediance Strap

The strap can be used for both endurance and strength training activities and recognizes various types of exercises, movement patterns, training volume and other insights that can help you learn how well your body is responding to your training.

The Speediance Strap is a screen-free wearable that collects data related to your sleep, training and core body temperature. It then uploads and shares this data to the Speediance Wellness Plus app, where it makes suggestions for your daily training and recovery based on this information. Similar to other wearables, the Speediance Strap assesses your readiness each day and can detect stress factors to determine if you should focus more on recovery on that day.

«With Speediance Strap, we are exploring how wearable data can function as part of a decision-support layer within a connected fitness system, rather than existing as isolated metrics,» Tao said in a statement.

Additionally, everyday insights (like core and recovery data) will be free to you unless you want to upgrade to the Wellness Plus access, which will come at an additional cost to receive long-term insights and AI planning.

It’s unclear when the Gym Nano will be available for purchase, but the Speediance Strap is expected to launch through a Kickstarter campaign in spring 2026.
