The telescope was first conceived all the way back in 1946 by Yale University astrophysicist Lyman Spitzer, Jr., who published a paper about the possible advantages of having what he called a “large space telescope” in orbit to help astronomers study the galaxies. The project finally got off the ground in the 1970s, and the telescope was designed so that astronauts could periodically upgrade it while still in orbit. Since it first broke through the atmosphere in 1990, the Hubble—named after astronomer Edwin Hubble, who proved the existence of other galaxies beyond the Milky Way—has taught us that the universe is 14 billion years old, that its expansion is speeding up, and so much more.
