“The space-based Hubble Space Telescope has looked farther into the cosmos than anything before it and has made great discoveries. Now it is about to be eclipsed by a telescope that will look even farther out — much farther. The long-awaited, $10 billion James Webb Space Telescope is scheduled for launch Dec. 18. In a series of hold-your-breath steps, it must travel to a stable position where Earth and the sun hold equal gravitational pull on it — about four times farther away from Earth than the moon. Then it must gingerly unfold its giant reflective mirror, much larger than Hubble’s and 100 times more powerful.” (11/22/21)
