The image shows the faintest red dwarf star spied by Hubble in globular cluster NGC 6397 (right above the very bright star in the centre of the image). The Advanced Camera found the faintest red dwarf stars (26th magnitude), which are cooler and much lower in mass than our Sun, and the dimmest white dwarfs (28th magnitude), the burned-out relics of normal stars. The light from the dimmest white dwarfs is equal to the light produced by a birthday candle on the Moon as seen from Earth.
