Scientists have greater access to the [[solar corona]] than they do to other stellar coronae, since it is inside our solar system{{cite web |last1=Franzen |first1=Harald |title=Astronomers Find Optical Light from the Corona of a Star Other Than Our Sun |url=https://www.scientificamerican.com/article/astronomers-find-optical/ |website=Scientific American |access-date=January 30, 2026 |language=en}}. This means that the coronae of other stars are still relatively poorly understood. |
