The astronomer Edwin Powell Hubble

An English surname derived from the Norman French given name Hubald

The Hubble Space Telescope

Hubble Space Telescope Hubble's constant Hubble Edwin Powell

An English surname derived from the Norman French name Hubald

{i} family name; Edwin P. Hubble (1889-1953), United States astronomer that observed distant galaxies, namesake for Hubble's Law; Hubble space telescope (launched by the USA in 1990 and transmits photos of galaxies and objects in space)

United States astronomer who discovered that (as the universe expands) the speed with which nebulae recede increases with their distance (1889-1953)

{i} ruckus, uproar; humps (on ice or a road); pile, heap; water pipe (for smoking)

Hubble constant

a number the expresses the rate of expansion of the universe; the velocity at which a distant object is receding from the Earth divided by its distance; its reciprocal gives the age of the universe

Hubble law

states that the velocity at which a distant object is receding from the Earth (as measured by its redshift) is proportional to its distance; observational evidence for an expanding universe

Hubble's constant

alternative spelling of Hubble constant

Hubble's law

alternative spelling of Hubble law

Hubble Space Telescope

powerful telescope that was launched into space by the United States in 1990 and transmits magnified photographs of galaxies and objects in space

Hubble Space Telescope

Most sophisticated optical observatory ever placed into orbit around Earth. Because it is above Earth's obscuring atmosphere, it can obtain images much brighter, clearer, and more detailed than ground-based telescopes can. Named for Edwin Hubble, it was built under NASA supervision and deployed on a 1990 space-shuttle mission. The reflector telescope's mirror optics gather light from celestial objects and direct it to an array of cameras and spectrographs (see spectroscopy). A defect in the primary mirror initially caused it to produce fuzzy images; in 1993 another shuttle mission corrected this and other problems. Subsequent missions to the HST have been for maintenance, repairs, and instrument upgrades

Hubble Telescope

a very powerful telescope (=a piece of equipment for making distant objects look larger and closer) which is attached to a satellite in space, going around the Earth, and can see much further into space than telescopes on Earth

Hubble's Law

{i} (Astronomy) scientific law that states that the speed at which distant galaxies move away from Earth is proportional to their distance from the observer

Hubble's constant

Constant used to relate the velocities of remote galaxies to their distances from Earth. Denoted H and named in honour of Edwin Hubble, it expresses the rate of expansion of the universe. Its actual value has been debated for decades; improved measurements have narrowed the range in which it falls to about 10.5-14 mi/second (17-23 km/second) per million light-years. The reciprocal of H gives the time, in seconds, since the galaxies began to separate from each other i.e., the approximate age of the universe. Hubble used the redshifts of distant galaxies measured by Vesto Slipher (1875-1969) and his own distance estimates of those galaxies to establish the cosmological velocity-distance law (Hubble law): velocity = H distance, according to which the greater a galaxy's distance, the faster it is receding. Derived from theoretical considerations and confirmed by observations, the Hubble law has made secure the concept of an expanding universe

hubble's constant

(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 reciprocal of the Hubble constant is the age of the universe

hubble's law

(astronomy) the generalization that the speed of recession of distant galaxies (the red shift) is proportional to their distance from the observer

hubble-bubble

{i} narghile, huka, hooka, smoking pipe that uses water to filter smoke; riot, panic

hubble-bubble

an oriental tobacco pipe with a long flexible tube connected to a container where the smoke is cooled by passing through water; "a bipolar world with the hookah and Turkish coffee versus hamburgers and Coca Cola"

Edwin P Hubble

born Nov. 20, 1889, Marshfield, Mo., U.S. died Sept. 28, 1953, San Marino, Calif. U.S. astronomer. He earned a degree in mathematics and astronomy at the University of Chicago, then made a brief foray into law before returning to astronomy. After earning his Ph.D., he began working at Mount Wilson Observatory. In 1922-24 he discovered that certain nebulae contained Cepheid variable stars; he determined that these were several hundred thousand light-years away (outside the Milky Way Galaxy) and that the nebulae they were in were actually other galaxies. In studying those galaxies, he made his second remarkable discovery (1927): that the galaxies were receding from the Milky Way at rates that increased with distance. This implied that the universe, long considered unchanging, was expanding (see expanding universe); even more remarkable, the ratio of the galaxies' speed to their distance was a constant (see Hubble's constant). Hubble's original calculation of the constant was incorrect; it made the Milky Way larger than all other galaxies and the entire universe younger than the surmised age of Earth. Later astronomers determined that galaxies were systematically more distant, resolving the discrepancy
