Which layer features arching columns that blast material into space?

The layer that features arching columns that blast material into space is the corona, which is the outer atmosphere of the Sun. During solar events such as coronal mass ejections (CMEs), the corona releases large amounts of plasma and magnetic field into space. These arching columns are often seen in images taken during solar eclipses or by solar observatories, showcasing the dynamic nature of the Sun's outer layers.
