Scientists have achieved a major milestone in fusion research: they sustained an artificial sun burning inside a machine for 102 seconds.
South Korea’s KSTAR fusion reactor (Korea Superconducting Tokamak Advanced Research) successfully maintained high-performance plasma at 100 million °C (180 million °F), roughly seven times hotter than the core of the Sun, for a record 102 seconds in high-confinement (H-mode) operation. This more than doubled the device’s previous performance in just a few years.
Fusion is the same process that powers the Sun and stars: it merges light atomic nuclei to release vast amounts of energy. If harnessed on Earth, it could provide nearly limitless clean electricity with no carbon emissions and minimal long-lived radioactive waste, often called the “holy grail” of energy.
The main challenge is controlling plasma, a superheated state of matter so energetic that no physical container can hold it. Scientists use powerful magnetic fields inside doughnut-shaped tokamaks to suspend and contain it.
KSTAR’s breakthrough came after upgrading its divertor (the component that handles the most intense heat) to tungsten. This new fully tungsten-lined interior allowed the reactor to sustain stable high-confinement plasma for 102 seconds, the first time it achieved this duration in the new configuration.
While KSTAR does not yet produce electricity, every extra second of stable operation yields critical data for future fusion power plants. The team’s next ambitious target is to maintain these extreme conditions for 300 seconds.

The victims are Lola and Ruby Moir who went viral in August 2025.
@CrimsonDesert_ 269hr in and can confirm in every aspect this game is beyond perfect, except 1, and it’s game breaking, SSD purging bs; stripped basically naked and still unarmed attacking when engaging the Kuku Gardening Pack. That fix had better be in the patch. Not a suggestion
@astro_reid@NASA@NASAArtemis Perfectly stunning. 10 month old me trying to toddle my excitement in 1969 then growing up through Apollo 17, this old soul is youthfully renewed. Damn fine job you all. Just so Proud.
@BridgetPhetasy Newsflash you irrelevant 18-34’s, you’re playing inside the box we built for you from 97-05. How does it feel to be the 8(a) result of our SocEng experiment for the Boomers? You jumped right in with them. You’re a 4.2σ aberration in the dataset
@palehorse24660@BlastingThrough Well, because they have an editing department. Literally anything Hollyweird or Netflix could do would never, ever be cool enough. They’d be better served sending their employees through a SGM Vining course on how to be moderately less soy or dumb.
@elonmusk can we make an x-Comic tab and auto populate it with peak shitty war AI slop? Then have @grok make original comic scoring for this glorious fiction?
@HLC_actual Yeah it is. But @gghamari and @ArminNavabi have been on a Ranger School 17 day insomnia marathon to keep this firmly in everyone’s brain. Get them some love HLC
