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.)
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.
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 ...
Hubble had studied the nebula previously at Yerkes and Mt. Wilson. [4] Hubble had taken photographic plates with the Yerkes 24-inch (60.96 cm) reflecting telescope in 1916. [5] Plates were taken using the same telescope in 1908 by F.C. Jordan, allowing Hubble to use a blink comparator to search for any changes over time in the nebula. [5]
The team nicknamed the star system Mothra due to its extreme magnification and brightness. Surprisingly, Mothra has appeared before, detected in Hubble observations nine years ago.
When our sun dies about 5 billion years from now it might look something like this glowing celestial display which was captured from 4,600 light-years away. Hubble image of a star exploding may ...
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 ...
