Something Bizarre Is Happening at the Sun's South Pole

Why was the Sun’s recent solar maximum twice as strong as predicted? In 2024-2025, the Sun entered a fiery active phase that completely defied expectations. But thanks to NASA's Parker Solar Probe, we now have observations taken from inside the Sun's atmosphere, which could help explain what’s powering the unusual eruptions. What’s really going on inside our star? And should we be worried here on Earth? ▀▀▀▀▀▀ 0:00 What’s Happening to the Sun? 1:59 Solar Cycle 25 4:34 Where Is the Tachocline? 6:06 Parker Solar Probe 9:13 Solar Switchbacks 12:38 The Sun’s South Pole 16:51 May 2024 Geomagnetic Storm 20:48 Plasma Storms 22:37 Risk to Earth 25:33 Future Solar Missions ▀▀▀▀▀▀ To stay on top of space news, sign up to the Astrum newsletter: https://astrumspace.kit.com A huge thanks to our Patreons who help make these videos possible.
