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.»

My CES 2026 Secret Weapon? This New Wearable AI Note-Taking Pin From Plaud

During a week of information overload, I’m outsourcing my memory to the Plaud NotePin S.

CES is always one of the most hectic weeks of the year for CNET journalists — myself included. I’ll be jumping between booths, often speaking to multiple different companies within the span of an hour, having interesting and intense conversations about different products as I go.

Sometimes these conversations begin before I’ve even had a chance to pull my recorder from my bag, never mind switch it on. Often I end up scribbling down extra details or quotes in my notepad — a fun challenge for my memory and eyes when the time comes to sit down and write and I’m forced to decipher my own handwriting.

Not this year, though. At CES 2026, AI note-taking company Plaud is launching its new NotePin S, an AI wearable that can clip to your collar, strap onto your wrist, hang around your neck or cling to your shirt with a magnet and record your conversations as you go about your day.

Plaud sent me this updated version of the NotePin ahead of CES, so I’ll be able to test it out as I wander the show floors. Just as with the previous version of the pin and the Plaud Note Pro, which the company announced back in August, the NotePin S connects to your phone via Bluetooth, and transcriptions of your conversations will appear in the Plaud app.

I already expect the NotePin S, which is a sleek pill-shaped device that’s smaller than a USB stick, to be a game changer for me as I roam the halls of CES. In a briefing ahead of the show, Plaud said that the pin had been successfully tested out at the Dreamforce conference earlier this year, so I know the dual microphones, which have a range of around 9.8 feet, are capable of working well in a noisy convention center.

To activate the recording, all I’ll need to do is long press on the front of the pin. But the feature I’m most looking forward to testing out is the press to highlight button on the pin, which will allow me to mark key moments in conversations so they’ll be easy to find when I come to look through my transcriptions later.

I’m also glad that, thanks to the range of the wearable accessories bundled with the NotePin S, the device will work with a variety of different outfits. In such a busy environment, I might be tempted to use the lanyard to carry it around my neck, but on the days I’m wearing a jacket, the lapel clip might be more suitable. For sit-down interviews, I’m tempted to switch to wristband so that I can press to highlight with the least amount of intrusion into the conversation.

For when I’m back home, conducting interviews from the comfort of my office, Plaud has another new toy for me to play with. At CES the company also announced Plaud Desktop — an AI notetaker designed to bridge in-person and online meetings by capturing your conversations natively.

This means no intrusive meeting bots joining your call. (If you know, you know.) Instead, it will sit on your computer and detect when a meeting is taking place, record that meeting discreetly and then provide a context-rich summary within your Plaud account.

The most appealing part of this for me is the idea that all of my notes, meetings and conversations — whether captured by my wearable or my computer — will be accessible and organized in one place.

Both the NotePin S and Plaud Desktop will be available immediately, with the pin costing $179 (£159).
