The Hubble Space Telescope (often referred to as 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 both as a vital research tool and as a public relations boon for astronomy.The Hubble telescope is named after astronomer …

The James Webb Space Telescope has a mass that is about half of Hubble Space Telescope's mass. The JWST has a 6.5-meter (21 ft)-diameter gold-coated beryllium primary mirror made up of 18 separate hexagonal mirrors. The mirror has a polished area of 26.3 m 2 (283 sq ft), of which 0.9 m 2 (9.7 sq ft) is obscured by the secondary support struts, giving a total collecting area of …

Hubble (en anglais : Hubble Space Telescope, en abrégé HST ou, rarement en français, TSH [2]) est un télescope spatial conçu par la NASA avec une participation de l'Agence spatiale européenne, opérationnel depuis 1990.Son miroir de grande taille (2,4 m de diamètre), qui lui permet de restituer des images avec une résolution angulaire inférieure à 0,1 seconde d'arc, …

O Telescópio Espacial Hubble (em inglês Hubble Space Telescope, HST) é um satélite artificial não tripulado que transporta um grande telescópio para luz visível e infravermelha.Foi lançado pela NASA, agência espacial estadunidense, em 24 de abril de 1990, a bordo do ônibus espacial (em Portugal, vaivém espacial) Discovery (missão STS-31).O Hubble já recebeu várias visitas …

The reciprocal of H 0 is the Hubble time. A recent 2011 estimate of the Hubble constant, which used a new infrared camera on the Hubble Space Telescope (HST) to measure the distance and redshift for a collection of astronomical objects, gives a value of H 0 = 73.8 ± 2.4 (km/s)/Mpc.
