A graph of the velocity of recession or approach of the stars in a spectroscopic binary.
Radiation Pressure ...
Hubble constant (NASA Thesaurus) The rate at which the velocity of recession of the galaxies increases with distance.
Definition: Hubble constant; (E.P. Hubble; 1925): The constant which determines the relationship between the distance to a galaxy and its velocity of recession due to the expansion of the Universe.
The constant which determines the relationship between the distance to a galaxy and its velocity of recession due to the expansion of the Universe.
Hubble's Law Law that relates the observed velocity of recession of a galaxy to its distance from us. The velocity of recession of a galaxy is proportional to its distance. [More Info: Photo Album] ...
Unless Earth is the center of the universe--which astronomers ceased to believe long ago--this meant that galaxies everywhere were receding from each other, and that an observer anywhere would observe the same effect, a velocity of recession ...
The linear relation between the velocity of recession of a distant object and its distance from us, v = H0d.
human genome project - (n.)
An international protect to map the entire genome of Homo sapiens.
He showed, from spectra of the galaxies, that there was an increase in the velocity of recession with distance.
always expanding but maintaining a constant average density, matter being continuously created to form new stars and galaxies at the same rate that old ones become unobservable as a consequence of their increasing distance and velocity of recession.
By Hubble's law it is thought that the velocity of recession of an object is proportional to its distance from us. The exact speed is determined by Hubble's constant, H0.
If Einstein's cosmological constant is zero, then a flat Universe will go on expanding forever, but the velocity of recession between any two objects would approach zero at large times. [G97] ...
Hubble constant (H): A measure of the rate of expansion of the universe; the average value of velocity of recession divided by distance; about 70 km/s/megaparsec.

329. Radial Velocity Curve
A graph of the velocity of recession or approach of the stars in a spectroscopic binary.
In terms of the net velocity of recession between source and observer (that is, the radial component of their relative velocity, with a positive value meaning that the two are moving apart, a negative value that they are approaching), ...
