Get the next 6 issues of BBC Sky at Night Magazine for just £9.99A scorching, fiery Halloween pumpkin is revealed in an image highlighting the active regions of our Sun.
This fiery jack o’ lantern is actually an image of our Sun captured by NASA’s Solar Dynamics Observatory, which observes our host star as it orbits Earth.
The active regions in the image are brighter because those areas emit more light and energy. They are actually intense magnetic fields hovering in the Sun’s corona; the outermost part of the Sun’s atmosphere.
