网页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 Telescope - HubbleSite
网页The telescope has beamed hundreds of thousands of celestial images back to Earth during its time in space. Hubble is a Cassegrain reflector telescope. Light from celestial objects travels down a tube, is collected by a bowl-like, inwardly curved primary mirror and reflected toward a smaller, dome-shaped, outwardly curved secondary mirror.

Reflecting Telescope: Definition, Optics, Design and Diagram
网页2023年2月2日 · Reflecting telescope, also called a reflector, is a telescope that uses a combination of curved mirrors that reflect light and form an image of a distant object. In astronomy, it is used to examine the visible region of the electromagnetic spectrum as well as the shorter (ultraviolet) and longer (infrared) wavelength regions adjacent to it.
Telescopes 101 - NASA Science
网页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 […]
6.1: Telescopes - Physics LibreTexts
网页2022年4月11日 · The most important functions of a telescope are (1) to collect the faint light from an astronomical source and (2) to focus all the light into a point or an image. Most objects of interest to astronomers are extremely faint: the more light we can collect, the better we can study such objects.
