Unraveling the Mysteries of the Sun's Atmosphere

The Sun, our nearest star, is more than just a blazing ball of fire. Its atmosphere, hotter than its already scorching surface, presents a puzzle that has intrigued scientists for years. How does the Sun's magnetic field heat its chromosphere to 10,000 degrees - and its corona to more than a million degrees? This enigma holds significant implications for Earth, as the Sun's corona hosts powerful explosions and eruptions that can trigger space weather events affecting our technology-dependent society. From mesmerizing auroras to disruptions in communication systems and satellite operations, the Sun's activity touches our daily lives in unexpected ways.

This talk will delve into the recent strides made in understanding the Sun's atmospheric dynamics. Thanks to breakthrough observations from space-based telescopes such as NASA's IRIS and SDO, coupled with advancements in supercomputing, we are gaining deeper insights into the mechanisms driving solar heating. Moreover, we will explore the upcoming frontier in solar research, with future observatories including NASA's MUlti-slit Solar Explorer (MUSE) mission poised to revolutionize our understanding of the Sun's behavior and its impact on our planet and beyond.
