How do space telescopes like Hubble and James Webb help us understand the universe?

Space telescopes like the Hubble and James Webb have revolutionized our understanding of the universe. These telescopes operate beyond the distorting effects of Earth's atmosphere and can see further into space and time than ground-based telescopes.

The Hubble Space Telescope, launched in 1990, has provided us with stunning images of distant galaxies and helped us understand the age and expansion of the universe. It has also observed the atmospheres of planets outside our solar system, and discovered new moons around Pluto. The James Webb Space Telescope, set to launch in 2021, will further our understanding of the universe by observing the formation of stars and galaxies, and studying the atmospheres of exoplanets in detail.

These telescopes have allowed us to see deeper into space and further back in time, giving us a glimpse of the early universe. By studying distant objects, we can learn about the evolution of galaxies, the nature of dark matter and dark energy, and the origins of the universe itself.
