NASA Shares Image of a Luminous Blue Star for Hubble Space Telescope’s 31st Birthday

NASA has shared a beautiful picture of a blue star to mark the 31st birthday of its Hubble Space Telescope. Called AG Carinae, it is located approximately 20,000 light-years away and is not just a luminous dot in the sky, but a glowing gas-and-dust nebula waging a battle within itself to avoid self-destruction.
