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.»

Google Could Revive Last Year’s Bright Pink Color for the Pixel 10a

Google’s upcoming Pixel 10a is expected to launch in February with some new colors, including one popular ask.

The Google Pixel 9a is one of Google’s most affordable Pixel phones, and it includes one of the most frequently requested colors — bright pink. With the Google Pixel 10a rumored to launch in February, we’re already getting a hint at the colors the new model will come in.

According to Roland Quandt, a regular mobile leaker on Bluesky, the Google Pixel is expected to be offered in obsidian (black), berry (pink), fog (light gray), and lavender colors. However, it’s the berry hue that is intriguing customers.

A representative for Google did not immediately respond to a request for comment.

«I always love to see phones come in vibrant colors, and it’s especially welcome in more budget-friendly options,» said Abrar Al-Heeti, senior technology reporter at CNET. «Yes, we tend to slap a case on our phones anyway, but just knowing your phone touts a bold color can make it feel like more of a statement piece, rather than a bland piece of tech.»

Pink is one of the most requested color options for the Pixel phones. CNET sister site Mashable loved the color when it debuted on the Pixel 9. Phone rivals like Apple and Samsung are usually expected to offer a pink color option in their flagship and midrange phone lineups, so it’s not surprising to see the berry color on the Pixel 10a.

«I’ll say that Google loves having Pixel phones in pink,» said Patrick Holland, CNET managing editor. «The Pixel 9 and 9a come in peony (a bright, bold pink) and the 9 Pro in rose quartz (a more muted pink). The Pixel 10 series lacks any pinkish hues.»

Quandt also says that the Pixel 10a will have 128GB and 256GB storage models, and will launch in mid-February. That’s earlier than expected compared with the Pixel 9a, which was revealed in mid-March 2025 for a launch on April 10. In terms of specifications, we expect the Pixel 10a to be a modest upgrade compared with previous generations. According to leaks, the Pixel 10 is unlikely to feature a newer Tensor G5 chip, and it’s likely to retain the same overall design as the Pixel 9a.

One leaker, Mystic Leaks on Telegram, expressed disappointment and revealed additional specs, including the absence of a telephoto lens, UFS 3.1 storage, a Tensor G4 chip, a 2,000-nit display and no Magic Cue, which is Google’s AI feature for the Pixel 10.
