- an optical instrument for making distant objects appear larger and therefore nearer. One of the two principal forms (refracting telescope, or refractor ) 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, or reflector ) 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.
- the constellation Telescopium.
- consisting of parts that fit and slide one within another.
- to force together, one into another, or force into something else, in the manner of the sliding tubes of a jointed telescope.
- to shorten or condense; compress: to telescope the events of five hundred years into one history lecture.
- to slide together, or into something else, in the manner of the tubes of a jointed telescope.
- to be driven one into another, as railroad cars in a collision.
- to be or become shortened or condensed.
- an optical instrument for making distant objects appear larger and brighter by use of a combination of lenses (refracting telescope) or lenses and curved mirrors (reflecting telescope)
- any instrument, such as a radio telescope, for collecting, focusing, and detecting electromagnetic radiation from space
- to crush together or be crushed together, as in a collision
- to fit together like a set of cylinders that slide into one another, thus allowing extension and shortening
- to make or become smaller or shorter
