The principle remains the same, the shape of the lens or mirror in a telescope concentrates light, and that is what we see when we look into a telescope. These elements are called optics. The most powerful telescopes today can see very …

NettetThis estimate is called the Hubble Constant, and scientists have been fine-tuning it ever since. The Hubble Space Telescope was launched in 1990, one of its major goals being to pin down the Hubble Constant. In 2001, a team studying supernovae with Hubble, along with ground-based optical telescopes, established a rate of 72 ± 8 km/sec/Mpc.

NettetHow Hubble works Hubble orbits Earth at an altitude of roughly 570 kilometers (350 miles). At its core, Hubble is a 13-meter-long tube (43 feet) opened to space on one end. Light travels through the tube to a bowl-shaped, 2.4-meter-wide (94.5-inch) main mirror and bounces up to a secondary mirror.
