Images from ESA’s Solar Orbiter offer the best look yet at a source region of the solar wind - and challenge our view of the continuous particle stream from the Sun.
Deciphering the magnetic origins of the Sun's hot corona: developing a framework for coronal heating by probing the elusive photosphere-corona connection
Using unique observational data and computer simulations, the MPS scientist is striving to understand the incredibly hot temperatures in the solar corona.
For the first time, images of the Sun have been taken from a distance of only 77 million kilometres enabling a completely new view of our star possible.
In his doctoral thesis, Sudip Mandal investigated how special pressure waves help maintain temperatures of several million degrees in the outermost solar atmosphere.
