Its story

Some 312 light-years away, within Canis Major, shines this white type A star. Its light set out around 1714, the year Daniel Fahrenheit invented the mercury thermometer and temperature ceased to be a sensation and became a number. Hotter and more luminous than the Sun, it is a sharp flare stitched into the celestial dog's coat as it follows Orion's steps each night.
