Happy birthday to the Hubble Space Telescope, launched from the Kennedy Space Center #OTD in 1990. Here's to a remarkable 35 years of imaging the Cosmos. 🧪 🔭 ⚛️

Leave your favorite Hubble images in the replies!
False color image of the Bubble Nebula (NGC 7635) in Cassiopeia.A ghostly blue bubble sits among golden orange clouds of gas, punctuated by sharp violet pinpricks – young stars. Spiral galaxies NGC 4038 and NGC 4039 –– the Antennae Galaxies. White, blue, and red swirls of stars from two disrupted spiral galaxies captured mid-collision, with messy lanes of dark gas and dust stretching between their bright yellow cores. The globular cluster NGC 1866 in the Large Magellanic Cloud. A jewel box of tightly clustered white, blue, and red stars. False color image of the Lagoon Nebula captured by Hubble for its 28th anniversary in 2018. Red, purple, blue, green, yellow, and orange clouds surround a region of active star formation, with our view obscured by dark molecular clouds.

I know the universe is homogeneous and isotropic… but it annoys me that West, Texas, is not in West Texas.
