What is the name of NASA's most famous space telescope?

The story behind the answer

Hubble Space Telescope is correct because it’s NASA’s (with ESA) iconic orbiting observatory, launched in 1990 by the Space Shuttle Discovery. Circling Earth above the atmosphere, Hubble captures ultra-sharp images in visible and ultraviolet (and some infrared) light, leading to breakthroughs like measuring the universe’s expansion rate, evidence for dark energy, and the Hubble Deep Field—revealing thousands of galaxies in a tiny patch of sky.

The distractors are fictional (Millennium Falcon, Death Star) or not a NASA telescope (“Big Eye”). Named after astronomer Edwin Hubble, it once had a blurry mirror that astronauts famously fixed, making it even more legendary. Memory tip: Hubble hugs Earth (low orbit) and Hubble = history—Webb is newer and farther, but Hubble made the universe feel close.
