After long years of crisis, the breakthrough in understanding the inner structure of our home star has now been achieved. And two space probes allow deep insights into the sun's atmosphere.
There are around 100 billion stars in the Milky Way, but only one is so close that we can study it in detail: the sun. If we don't understand them, we won't understand the other stars either. And that causes big problems for solar researchers: 15 years ago, a mystery about the chemistry of the sun emerged after two measurement methods had led to contradictory models for its inner structure.
The classic method
