We Sent a Probe Into the Sun's Atmosphere. It Found More Questions.
About this video
The coronal heating problem has puzzled scientists for decades: how can the Sun's corona be millions of degrees hotter than its surface? Discover what the Parker Solar Probe found as it journeyed through the Sun's atmosphere, uncovering magnetic switchbacks and crossing the Alfven surface. Despite these findings, the energy budget of the Sun remains unsolved, leaving scientists with more questions than answers.
