Galaxies' Ancient Light: James Webb Telescope captures light emitted by galaxies a million years ago, revealing the universe's early stars.
Massive Folding Challenge: Due to its size, the telescope was folded for launch, unfolding in space over two weeks.
Long Road to Success: Proposed in 1996, faced delays, but finally launched successfully in 2021 after rigorous testing.
Reflecting Infrared: Its 21.3 feet gold-plated beryllium mirror optimally reflects infrared light, weighing 705 kilograms.
Remarkable Precision: Can spot a coin's 0.75-diameter from 64 kilometers away, equivalent to seeing a football pitch from 550 kilometers.
Remote Orbit: Unlike Hubble, it's 1.5 million kilometers away at the second sun-earth Lagrange point, making servicing impossible.
Tennis-Court Size: Boasting a diamond-shaped sunshield with a 69.5 feet diameter, it's as large as a tennis court.
