This NASA/ESA Hubble Space Telescope image shows one of the smallest objects ever seen around a normal star. Astronomers believe the object is a brown dwarf about 12 times more massive than Jupiter. Dubbed CHXR 73 B, it is the bright spot at lower right and orbits a red dwarf star called CHXR 73. Credit: NASA, ESA, and K. Luhman (Penn State University, USA)
