The Sun's So Bright, It's Spinning Slower

The video explores the mystery of the sun's surface layer spinning slower than the gas beneath it, a phenomenon studied using helioseismology and NASA's Solar Dynamics Observatory. It suggests that sunlight may act as a brake on the sun's rotation. The video also discusses the Martian meteorite NWA 7635, which indicates a volcano on Mars has been active for over two billion years, challenging our understanding of Martian geology and plate tectonics.
