A massive triple plasma burst from the sun is heading towards comet C204 UN271, the largest ever observed at 140km in diameter. This comet, exhibiting unusual activity far from the sun, will make its closest approach in 2031 during solar minimum. The solar energy from the recent explosions will likely energise the comet, potentially increasing its jet activity.

Comet UN271, the largest comet ever observed at 140 km across, is currently interacting with the sun’s energy. This interaction, characterised by solar flares and eruptions directed towards the comet, could potentially cause it to fragment, releasing a swarm of icy material into the solar system. The comet’s unique orbit, spending most of its time in interstellar space, makes it more susceptible to cosmic radiation, potentially making it more brittle and prone to ou ...
