The Sun appears as a red-hued marble with black branching strips and few bright dots in white with small haloes of pale blue and electric green. All around the edge of the Sun is a glow, appearing like short fur in orange, yellow, and two bright spots of white on the right and left sides.

Flaring, active regions of our Sun are highlighted in this image combining observations from several telescopes. High-energy X-rays from NASA's Nuclear Spectroscopic Telescope Array (NuSTAR) are shown in blue; low-energy X-rays from Japan's Hinode spacecraft are green; and extreme ultraviolet light from NASA's Solar Dynamics Observatory (SDO) is yellow and red.

All three telescopes captured their solar images around the same time on April 29, 2015. The NuSTAR image is a mosaic made from combining smaller images.
