'The sun's magnetic field is key to understanding the dynamic nature of our home star from the smallest to the largest scales,' scientist Daniel Müller said.
NASA and the European Space Agency's Solar Orbiter spacecraft has sent home the highest resolution images of our sun ever captured.ESA has shared four images of the sun's surface, revealing the detailed structure of the sun's photosphere, magnetic field, and corona.These images were snapped on March 22, 2023, when the Solar Orbiter was some 45 million miles from our star.
These granules are small, dynamic patterns of bright and dark areas caused by convection which play a crucial role in transporting energy from the sun's interior to its surface.The visible light image also reveals the sun's surface to be dotted with sunspots, which are dark patches on the photosphere caused by intense magnetic activity. Sunspots are cooler than their surroundings, with temperatures around 7,000 degrees Fahrenheit.
