(n) United States astronomer who discovered that (as the universe expands) the speed with which nebulae recede increases with their distance from the observer (1889-1953), Syn.Edwin Hubble, Edwin Powell Hubble
(n) (cosmology) the ratio of the speed of recession of a galaxy (due to the expansion of the universe) to its distance from the observer; the Hubble constant is not actually a constant, but is regarded as measuring the expansion rate today, Syn.Hubble's parameter, Hubble constant, Hubble parameter
(n) (astronomy) the generalization that the speed of recession of distant galaxies (the red shift) is proportional to their distance from the observer, Syn.Hubble law

n. A tobacco pipe, so arranged that the smoke passes through water, making a bubbling noise, whence its name. In India, the bulb containing the water is often a cocoanut shell. It is a simple type of hookah. [ 1913 Webster ]
n. A large astromical optical telescope placed into orbit around the earth, from which, in the absence of absorption and distortion by the earth's atmosphere, clear high-resolution images of astronomical objects can be obtained in the visible, infrared, and ultraviolet wavelengths. The telescope was launched into orbit on April 24, 1990. Since then the telescope has taken thousands of images, many of them unique, recording never before seen astronomical phenomena. Service missions were performed in 1993 and 1997, during which astronauts upgraded or replaced equipment on the telescope. Link to Hubble Telescope Information. [ PJC ]
