Watch a colossal loop of glowing red plasma shoot out from the sun
The sun unleashed a monster eruption of super-hot plasma Friday in back-to-back solar storms captured on camera by a NASA spacecraft.
The giant sun eruption, called a solar prominence, occurred on 16 November at 1 a.m. EST (0600 GMT), with another event flaring up four hours later. The prominence was so large, it expanded beyond the camera view of NASA's Solar Dynamics Observatory (SDO), which captured high-definition video of the solar eruption.
In the video, a colossal loop of glowing red plasma erupts from the lower left of the sun, arcing up and out of frame as it blasts away from the star.

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 article 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 ITER, 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 article in English on the KFE website, or in Korean in the Chosun Biz.
