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.»

Nintendo Switch 2: Every Reveal About the Console, New Games, Price, Release Date
The $450 console launches June 5, with Mario Kart World the highlight of its launch day game lineup.

The Nintendo Switch 2 console’s biggest reveal yet arrived Wednesday as part of the company’s latest Nintendo Direct event. This teed up a day of Switch 2 reveals that include its June 5 release date, a $450 price, its specs and its initial game lineup that extends from launch into 2026.
The console will be further buoyed by having Mario Kart World as a launch title, which will go on sale in either a $500 bundle with the Switch 2 or on its own for $80 — making the open-world racing game one of Nintendo’s most expensive yet. Other games announced, such as Donkey Kong Bananza, are being priced around $70, which matches the cost of 2023’s The Legend of Zelda: Tears of the Kingdom. That Zelda game and Breath of the Wild are among the original Switch titles that will get enhanced Nintendo Switch 2 Edition upgrades, a premium upgrade allowing players to get new features, modes and graphical enhancements that take advantage of the newer system’s capabilities.
Here are the top highlights from Nintendo’s console event, all of the games we’ve heard about so far (including new titles, Nintendo Switch 2 Editions and GameCube games coming to Nintendo Switch Online) and all of our coverage so far. You can also check out our Nintendo Switch 2 live blog for even more updates about the Switch 2 as we learn them.

Nintendo Switch 2 console
The Nintendo Switch 2’s specs saw a noticeable technical bump over the Switch. The Nintendo Switch 2 has a 7.9-inch, 1080p resolution LCD that supports a 120Hz refresh rate — matching what we now see on most Android phones. When the Switch 2 is docked, compatible games can run in 4K resolution. The new dock also includes a cooling fan.
The Switch 2 comes with 256GB of internal storage, and the new Switch 2 Game Cards will load games faster. For digital libraries, however, the Switch 2 will only work with microSD Express cards, which are different from the microSD cards that are compatible with the prior Nintendo Switch. Nintendo will have a Software Transfer feature available to help move games and data from the original Switch to the Switch 2.
The new Joy-Con for the controllers will support mouse controls, and a new C button will be part of a new GameChat communication feature that allows both voice and video chat. There’s also a Nintendo Switch 2 Camera, allowing players to see each other.
The Switch 2 also adds a second USB-C port to the top of the system, which Nintendo says can help connect its new camera accessory or charge the console when playing in tabletop mode. Nintendo also revealed a new Switch 2 Pro Controller with the C button and customizable GL and GR buttons on the back.
Following the presentation, Nintendo unveiled the system’s price of $450 in the US. It will also sell the Switch 2 bundled with a digital version of Mario Kart World for $500.
Mario Kart World
Mario Kart World removes its traditional boundaries and lets drivers roam freely across an entire world of race courses. The game will get its own Nintendo Direct later this month, where we’ll see additional details, but we already know it’ll include traditional races and a Free Roam mode, much like in the Forza Horizon series.
Getting the game bundled for an extra $50 on the cost of the Switch 2 might be the move if you are interested in the game, because Nintendo announced on its website that standalone copies of Mario Kart World will cost $80.
Joy-Con 2 C button and GameChat
Nintendo’s rolling out its new C button across several new Switch 2 controllers. The button will be used for the new GameChat communication features without a headset. The button will be used alongside a microphone on the console itself, which Nintendo says can be used whether it’s docked to a TV or in handheld mode.
In its teaser video, Nintendo promises the microphone will be able to cancel out loud background noises. GameChat will also work with a Nintendo Switch 2 Camera, allowing video chat and various camera-based game modes in supported titles. GameChat will be free at launch through March 31, 2026.
Nintendo Switch 2 Edition games upgrade titles
The Nintendo Switch 2 will play three types of games: original Switch games, Switch 2 games and Switch 2 Edition games that will receive substantial enhancements. For many of these Switch 2 Edition games, you’ll need to buy an upgrade pack if you own the original for Switch. Many of them will get more than just enhanced graphics in the upgrade; for example, Super Mario Party Jamboree will get new games that support the new Joy-Cons’ mouse controls, audio recognition and video camera gameplay options through the Switch 2 Camera.
Other Nintendo Switch games that are getting Switch 2 Edition options include The Legend of Zelda Breath of the Wild, The Legend of Zelda Tears of the Kingdom, Kirby and the Forgotten Land, Metroid Prime 4 Beyond and Pokemon Legends: Z-A. Enhancements vary: The Zelda games will start working with a companion phone app for maps and sending schematics to friends, while Kirby will get a new story that’s exclusive to the Switch 2 Edition. On the third-party side, Civilization 7 will get mouse controls.
Nintendo did not announce what upgrade packs will cost. However, some Switch games will get free updates that will improve performance or enhance features when playing them on the Switch 2. The Switch games getting these updates include:
- Arms
- Captain Toad: Treasure Tracker
- Super Mario Odyssey
- Super Mario 3D World + Bowser’s Fury
- Clubhouse Games: 51 Worldwide Classics
- The Legend of Zelda: Link’s Awakening
- The Legend of Zelda: Echoes of Wisdom
- Game Builder Garage
- New Super Mario Bros. U Deluxe
- Pokemon Scarlet
- Pokemon Violet
- Big Brain Academy: Brain vs. Brain
Hyrule Warriors: Age of Imprisonment
Hyrule Warriors: Age of Imprisonment is a new game set in the world of Zelda that tells the story that leads into The Legend of Zelda: Tears of the Kingdom. This appears to be similar to how Hyrule Warriors: Age of Calamity told the story of a war that led to the events of Breath of the Wild. The teaser shows Zelda discovering that she’s arrived in the past of Hyrule, and the game will expand on how she gets involved in the corresponding Imprisonment War.
Nintendo Switch 2 games
Several other first- and third-party games were spotlighted during the Switch 2 Direct. These include Donkey Bananza, one of the first 3D platforming games featuring DK since 1999’s Donkey Kong 64. Kirby will also return to the racing genre in Kirby Air Riders, which comes more than 20 years after the GameCube racer Kirby’s Air Ride. DragXDrive will use mouse controls to control a futuristic wheelchair basketball game in which players will simulate push and pull motions to control their character.
An onslaught of Switch 2 third-party games were quickly shuffled through during the Direct, which I list below. An unnamed James Bond game is in development at Hitman studio IO Interactive, as is a darker title from Elden Ring creator FromSoftware called The Duskbloods, which will be exclusive to the Switch 2.
The full list of announced Nintendo Switch 2 games includes:
