For a special SpaceTime listener offer, visit store.insta360.com and use the promo code SPACETIME at checkout. Help support SpaceTime and get a great deal. Win/win! In this episode of SpaceTime, we delve into some astounding revelations in solar physics and planetary science, including the extreme temperatures of solar flares, new insights into the formation of Jupiter's core, and the tantalising possibility of life evolving on nearby exoplanets. Solar Flares Hotter Than Ever Imagined Recent research has revealed that solar flares can reach temperatures exceeding 60 million degrees Celsius, a staggering six and a half times hotter than previously believed. This groundbreaking finding, published in the Astrophysical Journal Letters, may provide answers to a long-standing mystery regarding solar flare spectral lines. The study suggests that positively charged particles, or ions, are heated more intensely than electrons during these explosive events, leading to a significant revision of our understanding of solar flare dynamics. New Insights into Jupiter's Core Formation A new study challenges previous theories regarding the formation of Jupiter's core, suggesting that a giant impact may not be responsible for the planet's dilute core structure. Instead, it appears that Jupiter's core formed gradually through the absorption of heavy and light materials during its evolution. This revelation, supported by advanced computer simulations, indicates that the core does not have a distinct boundary but rather blends smoothly into the surrounding hydrogen layers, reshaping our understanding of gas giant formation. Could Life Thrive on Nearby Exoplanets? Exciting new research posits that life may be evolving right now on some of Earth's nearest exoplanets, despite the high levels of radiation they receive. Scientists have drawn parallels between the harsh conditions on these exoplanets and early Earth, where life first emerged amidst extreme ultraviolet radiation.
