There are two main puzzles about the Sun which this advancement will help address. First is the coronal heating problem. Though the core of the Sun is at a temperature of about 15 million degrees, its outer layer, the photosphere is a mere 5700 degrees hot. However, its corona or outer atmosphere, which stretches up to several million kilometres beyond its surface, is much, much hotter than the surface. It is at a temperature of one million degrees or more. What causes the atmosphere of the Sun (corona) to heat up again, though the surface (photosphere) is cooler than the interior?

Unknown titles. The group has measured the global magnetic field of the Sun’s corona, or outer atmosphere, for the very first time. This research has been published in the journal Science.

It is at a temperature of one million degrees or more. What causes the atmosphere of the Sun (corona) to heat up again, though the surface (photosphere) is cooler than the interior? That is the question which has baffled solar physicists. Popular attempts to explain this puzzle invoke the magnetic field of the corona. Hence the present work will help understand and Summary
