James Webb Space Telescope

NASA/ESA/CSA · Launched 2021-12-25 · Sun-Earth L2

The largest telescope ever flown, parked at the Earth-Sun L2 point about 1.5 million kilometres out, permanently shaded by a tennis-court-sized sunshield. It sees in infrared, which means it sees the earliest galaxies and through the dust where stars are being made.
