Astronomers at NASA have spotted the Sun beaming a remarkable, joyous grin, in a sunny spectacle destined to put a smile on your dial.

It seems the Sun was in a good mood. A photo of the Sun taken from a National Aeronautics and Space Administration (NASA) satellite on Thursday appeared to show a smile on the surface of our nearest star. "Say cheese! Today, NASA's Solar Dynamics Observatory caught the Sun 'smiling'. Seen in ultraviolet light, these dark patches on the Sun are known as coronal holes and are regions where fast solar wind gushes out into space," the American space agency wrote in the caption of the post.
