May 26, 2024 · telescope, device used to form magnified images of distant objects. The telescope is undoubtedly the most important investigative tool in astronomy. It provides a means of collecting and analyzing radiation from celestial objects, even those in the far reaches of the universe.
Apr 24, 1990 · Throughout the history of science, revolutionary instruments propel our understanding with their landmark discoveries. The Hubble Space Telescope is a testament to that concept. Its design, technology and serviceability have made it one of NASA's most transformative observatories.
Telescopes Astronomers observe distant cosmic objects using telescopes that employ mirrors and lenses to gather and focus light. The size of the main mirror or lens determines how well a telescope can collect light. The larger a mirror or lens, the more light it collects, and the better its ability to detect fainter objects. Refracting […]
Dec 25, 2021 · The James Webb Space Telescope is a giant leap forward in our quest to understand the Universe and our origins. Webb is examining every phase of cosmic history: from the first luminous glows after the Big Bang to the formation of galaxies, stars, and planets to the evolution of our own solar system.
