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 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 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.)
Smile, Hubble! You turn 31 today. The Hubble Space Telescope launched into orbit on April 24, 1990, and it's been looking into the far reaches of space and beaming images back to us ever since. In ...
Distance measures are used in physical cosmology to give a natural notion of the distance between two objects or events in the universe.They are often used to tie some observable quantity (such as the luminosity of a distant quasar, the redshift of a distant galaxy, or the angular size of the acoustic peaks in the cosmic microwave background (CMB) power spectrum) to another quantity that is ...
