NASA is celebrating the 36th anniversary of the Hubble Space Telescope in Earth’s orbit, sharing a new image of the Trifid Nebula, nicknamed the “Cosmic Sea Slug,” first revealed in 1997.

The school-bus-sized telescope has since made nearly 1.7 million observations, targeting about 55,000 astronomical objects.

Its discoveries have resulted in over 22,000 scientific papers and more than 1.3 million citations, making it one of the most influential scientific instruments ever built.

Hubble was launched on April 24, 1990.

NASA is celebrating the 36th anniversary of the Hubble Space Telescope with a stunning new look at the Trifid Nebula, a star-forming region about 5,000 light-years away. Powerful ultraviolet light from massive stars has carved out this glowing bubble, triggering new waves of star birth. First imaged in 1997, Hubble revisits this scene nearly 30 years later with sharper vision. The image reveals a structure nicknamed the “Cosmic Sea Slug,” including a jet from Herbig-Haro 399, showing how young stars actively shape their surroundings. NASA/ESA/STScI et al. / SWNS

Hubble trained on NGC 6302, known as the "Butterfly Nebula," to observe it across a more complete spectrum of light, from near-ultraviolet to near-infrared, helping researchers better understand the mechanics at work in its technicolor "wings" of gas.Hubble trained on NGC 6302, known as the “Butterfly Nebula,” to observe it across a more complete spectrum of light, from near-ultraviolet to near-infrared, helping researchers better understand the mechanics at work in its technicolor “wings” of gas.
