What happens when the Sun runs out of fusion fuel?
Researchers who specialize in stellar evolution have long known that the inner planets are in danger. The trouble starts in the distant future when the Sun's core runs out of hydrogen fuel for nuclear fusion. To keep the fires burning, the sun will begin to fuse hydrogen outside the core, in a layer closer to the stellar surface. This will turn the Sun into a red giant, at least 200 times wider than it is today. Mercury, Venus, Earth and possibly even Mars could be engulfed.

KSTAR aims for longer plasmas
At the Korea Institute of Fusion Energy (KFE), the KSTAR tokamak recommenced operations in December after a major upgrade to replace the device's carbon divertor with a tungsten divertor.
According to an on the KFE website, the original carbon divertors could take a thermal load of 5MW/m², whereas the tungsten divertor can take 10MW/m². The upgrade is critical to the goal of sustaining a 100-million-degree plasma for 300 seconds by 2026. Data from the operational campaign will be directly relevant to °ÄÃÅÁùºÏ²Ê¸ßÊÖ, which will operate a tungsten divertor under similar plasma conditions in terms of shape and structure.
This testing campaign will continue through February 2024. Read more about the plans in this in English on the KFE website, or in Korean in the .
