A new image from the NASA/ESA Hubble Space Telescope shows a distant galaxy as it begins to align with and pass behind a Sun-like star sitting nearer to...

Composite image of the Fomalhaut star system. The ALMA data, shown in orange, reveal the distant and eccentric debris disk in never-before-seen detail. The central dot is the unresolved emission from the star, which is about twice the mass of our Sun. Optical data from the NASA/ESA Hubble Space Telescope is in blue; the dark region is a coronagraphic mask, which filtered out the otherwise overwhelming light of the central star.
