The Hubble length or Hubble distance is a unit of distance in cosmology, defined as cH −1 — the speed of light multiplied by the Hubble time. It is equivalent to 4,420 million parsecs or 14.4 billion light years. (The numerical value of the Hubble length in light years is, by definition, equal to that of the Hubble time in years.)
Hubble's latest image share is a good one for fans of cosmic razzle-dazzle.You're seeing NGC 6717, a globular cluster that forms a piece of the constellation Sagittarius. But where it appears to ...
The giant elliptical galaxy ESO 325-4. An elliptical galaxy is a type of galaxy with an approximately ellipsoidal shape and a smooth, nearly featureless image. They are one of the three main classes of galaxy described by Edwin Hubble in his Hubble sequence and 1936 work The Realm of the Nebulae, [1] along with spiral and lenticular galaxies.
Spiral galaxy UGC 12591 is classified as an S0/Sa galaxy. [1]The Hubble sequence is a morphological classification scheme for galaxies invented by Edwin Hubble in 1926. [2] [3] It is often known colloquially as the “Hubble tuning-fork” because of the shape in which it is traditionally represented.

NGC 1300, viewed nearly face-on; Hubble Space Telescope image. A barred spiral galaxy is a spiral galaxy with a central bar-shaped structure composed of stars. [1] Bars are found in about two thirds of all spiral galaxies in the local universe, [2] and generally affect both the motions of stars and interstellar gas within spiral galaxies and can affect spiral arms as well.
NASA's Hubble Space Telescope captured one such stunning scene in an image shared with the public on Saturday. NGC 7764A, as the galaxies are collectively known, is roughly 425 million light-years ...
