an optical instrument for making distant objects appear larger and therefore nearer. One of the two principal forms (refracting telescope) consists essentially of an objective lens set into one end of a tube and an adjustable eyepiece or combination of lenses set into the other end of a tube that slides into the first and through which the enlarged object is viewed directly; the other form (reflecting telescope) has a concave mirror that gathers light from the object and focuses it into an adjustable eyepiece or combination of lenses through which the reflection of the object is enlarged and viewed. Compare radio telescope.

–adjective
3.

–verb (used with object)
4.
to force together, one into another, or force into something else, in the manner of the sliding tubes of a jointed telescope.
5.
to shorten or condense; compress: to telescope the events of five hundred years into one history lecture.
–verb (used without object)
6.
to slide together, or into something else, in the manner of the tubes of a jointed telescope.
7.
to be driven one into another, as railroad cars in a collision.
8.
to be or become shortened or condensed.
[Origin: 1610–20; tele-1+ -scope; r. telescopium (< NL; see -ium) and telescopio (< It)]
An arrangement of lenses or mirrors or both that gathers visible light, permitting direct observation or photographic recording of distant objects.
Any of various devices, such as a radio telescope, used to detect and observe distant objects by their emission, transmission, reflection, or other interaction with invisible radiation.
v.

v.
tr.

To make more compact or concise; condense.
v.

To slide inward or outward in or as if in overlapping cylindrical sections: a camp bucket that telescopes into a disk.
[New Latin telescopium or Italian telescopio, both from Greek tēleskopos, far-seeing : tēle-, tele- + skopos, watcher; see spek- in Indo-European roots.]
1648, from It. telescopio (used by Galileo, 1611), and Mod.L. telescopium (used by Kepler, 1613), both from Gk. teleskopos "far-seeing," from tele- "far" (see tele-) + -skopos "seeing," from skopein "to watch." Said to have been coined by Prince Cesi, founder and head of the Roman Academy of the Lincei (Galileo was a member). Used in Eng. in L. form from 1619. The verb meaning "to force together one inside the other" (like the sliding tubes of some telescopes) is first recorded 1867.
a kind of tube containing lenses through which distant objects appear closer Example: He looked at the ship through his telescope.

telescope[ˈteliskəup]verb
to push or be pushed together so that one part slides inside another, like the parts of a closing telescope Example: The crash telescoped the railway coaches.
An arrangement of lenses, mirrors, or both that collects visible light, allowing direct observation or photographic recording of distant objects. ◇ A refracting telescope uses lenses to focus light to produce a magnified image. Compound lenses are used to avoid distortions such as spherical and chromatic aberrations. ◇ A reflecting telescope uses mirrors to view celestial objects at high levels of magnification. Most large optical telescopes are reflecting telescopes because very large mirrors, which are necessary to maximize the amount of light received by the telescope, are easier to build than very large lenses.
Any of various devices, such as a radio telescope, used to detect and observe distant objects by collecting radiation other than visible light.
A device used by astronomers to magnify images or collect more light from distant objects by gathering and concentrating radiation. The most familiar kind of telescope is the optical telescope, which collects radiation in the form of visible light. It may work by reflection, with a bowl-shaped mirror at its base, or by refraction, with a system of lenses. Other kinds of telescopes collect other kinds of radiation; there are radio telescopes (which collect radio waves), x-ray telescopes, and infrared telescopes. Radio and optical telescopes may be situated on the Earth, since the Earth's atmosphere allows light and radio waves through but absorbs radiation from several other regions of the electromagnetic spectrum. X-ray telescopes are placed in space.
Gold"fish`\, n. (Zo["o]l.) (a) A small domesticated cyprinoid fish (Carassius auratus); -- so named from its color. It is native of China, and is said to have been introduced into Europe in 1691. It is often kept as an ornament, in small ponds or glass globes. Many varieties are known. Called also golden fish, and golden carp. See Telescope fish, under Telescope. (b) A California marine fish of an orange or red color; the garibaldi.
Tel"e*scope\ (t[e^]l"[-e]*sk[=o]p), a. Capable of being extended or compacted, like a telescope, by the sliding of joints or parts one within the other; telescopic; as, a telescope bag; telescope table, etc.
Re*flect"ing\, a. 1. Throwing back light, heat, etc., as a mirror or other surface. 2. Given to reflection or serious consideration; reflective; contemplative; as, a reflecting mind. Reflecting circle, an astronomical instrument for measuring angless, like the sextant or Hadley's quadrant, by the reflection of light from two plane mirrors which it carries, and differing from the sextant chiefly in having an entire circle. Reflecting galvanometer, a galvanometer in which the deflections of the needle are read by means of a mirror attached to it, which reflects a ray of light or the image of a scale; -- called also mirror galvanometer. Reflecting goniometer. See under Goniometer. Reflecting telescope. See under Telescope.
