Ultraviolet image of coronal loops on the Sun

Caption

This ultraviolet image of coronal loops on the Sun was taken using the 335 angström channel of the Atmospheric Imaging Assembly telescope on NASA’s Solar Dynamics Observatory. Earth is shown to scale. The image shows solar plasma at temperatures around 4.5 million degrees Fahrenheit (2.5 million degrees Celsius) colorized in blue. In this image, loops extend far from the solar surface without expanding much with height, which is counter to the expected physics according to the “garden hose” model of coronal loops.
