Learn how telescopes use mirrors and lenses to collect and focus light from different wavelengths of the electromagnetic spectrum. Find out how NASA designs and builds telescopes for visible, infrared, X-ray, and gamma ray astronomy.
Learn about the simple refracting telescope invented by Galileo in 1609, which he used to discover Jupiter's moons, Sunspots, Venus' phases, and Moon's features. Compare it with the Keplerian telescope, which has a different lens arrangement and produces an inverted image.
4 days ago · A telescope is a tool that astronomers use to see faraway objects. Most telescopes, and all large telescopes, work by using curved mirrors to gather and focus light from the night sky. The first telescopes focused light by using pieces of curved, clear glass, called lenses.
