The JWST, for example, is about 930,000 miles (1.5m kilometres) away -- approximately four times as far as the moon and far enough that radio signals sent from Earth, travelling at the speed of light, take about five seconds to reach it.
They're called space telescopes not just because they observe space, but because they're located in space.
