MAGNETISM UNVEILED Hot gas in the sun’s atmosphere flows along magnetic field lines (pale streaks) that puncture the surface. Sunspots with opposing magnetic polarity are blue and yellow in this false-color image.
A dust cloud, navigating the orbits of dozens of stars (blue), gets torn apart by the supermassive black hole in the center of the galaxy in this artist’s illustration.

BULL’S-EYE A blast of X-rays from a neutron star (center) illuminate dust clouds between the star and Earth (colored rings), as seen in this composite image. Red, green and blue correspond to low-, medium- and high-energy X-rays.
