NASA’s Solar Dynamics Observatory (SDO) captured this image of the Sun with sunspots in February 2013. The picture combines images from two SDO instruments: the Helioseismic and Magnetic Imager (HMI), which takes pictures in visible light that show sunspots, and the Advanced Imaging Assembly (AIA), which took an image in the 304 angstrom wavelength showing the lower atmosphere of the Sun, which is colorized in red.

The world’s first neutrino observation in a hydrogen bubble chamber. It was found November 13, 1970, on this photograph from the Zero Gradient Synchrotron’s 12-foot bubble chamber. The invisible neutrino strikes a proton where three particle tracks originate (lower right). The neutrino turns into a mu-meson, the long center track (extending up and left). The short track is the proton. The third track (extending down and left) is a pi-meson created by the collision. Image credit: Argonne National Laboratory.
