Happy Birthday #Hubble! It was launched #OTD April 24, 1990 on the Space Shuttle Discovery.
This year's anniversary image is of the Little Dumbbell Nebula, or M76.
M76 is a planetary nebula, a glowing cloud of gas ejected by a sun-like star at the end of its lifetime. The central bar structure is actually a ring seen edge-on. This was likely sculpted by a binary companion star. Two lobes extend from the bar to the left and right of the ring.
