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.

What is the significance of the age of NWA 7635 in understanding Martian volcanic activity?

In what ways does the geological history of Mars differ from that of Earth, based on the findings related to NWA 7635?
