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 Hubble Space Telescope (HST or Hubble) is a space telescope that was launched into low Earth orbit in 1990 and remains in operation. It was not the first space telescope, but it is one of the largest and most versatile, renowned as a vital research tool and as a public relations boon for astronomy.
Zooming In on the Andromeda Galaxy, also known as Gigapixels of Andromeda, is a 2015 composite photograph of the Andromeda Galaxy produced by the Hubble Space Telescope. It is 1.5 billion pixels in size, and is the largest image ever taken by the telescope. [1] At the time of its release to the public, the image was one of the largest ever ...
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 ...
Us Earthlings inhabit a solar system on one of the great spiral arms of the Milky Way galaxy.The legendary Hubble Space Telescope, orbiting Earth, peered inward and captured a vivid image of stars ...
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.
