The top 3

James Webb Space Telescope: Infrared Giant: Launched in December 2021, JWST is the largest space-based telescope ever built with a 6.5-meter primary mirror, optimized for infrared astronomy to observe the early universe and exoplanet atmospheres.
Hubble Space Telescope: Iconic Visible-Light Visionary: Deployed in 1990, Hubble is renowned for its clear views of deep space across ultraviolet, visible, and infrared light, with a 2.4-meter primary mirror, and has made over 1.5 million observations.
Nancy Grace Roman Space Telescope: Wide-Field Infrared Surveyor: Launched on August 30, 2026, the Roman Space Telescope features a 2.4-meter primary mirror like Hubble's but with a field of view over 100 times greater, designed for large surveys of dark energy, exoplanets, and infrared astrophysics.
