The Moon and Sun from space

NASA’s Solar Dynamics Observatory, two or three times a year, observes the moon traveling across the sun, blocking its view. While this obscures solar observations for a short while, it offers the chance for an interesting view of the shadow of the moon.    Image © NASA/SDO/LRO/GSFC

Blue Sun

Our Sun can be made to appear similar to a blueberry, by imaging it in a specific color of extreme violet light called CaK that is emitted by the very slight abundance of ionized Calcium in the Sun’s atmosphere, and then false color-inverting the image.    Image © Alan Friedman (Averted Imagination)
