What is Hubble's space binoculars?

Hubble Space Binoculars (HST) is one of the most important instruments in the history of astronomy. Hubble, which was launched in 1990, orbits the country at an altitude of approximately 589 km. Although the idea of ​​a cosmic telescope was originally conceived in 1946, it took 44 years of technical struggles and budget problems before it was actually put into operation. Hubble is part of the Great Observatory NASA program, which includes the Chandra X -ray Observatory, Spitzer Space Telescope and Compton Gamma Ray Observatory.

The Hubble Space Telescope is probably the most famous for its image known as Hubble Ultra Deep Field, which shows an extremely weak galaxy billions of light years. It is the farthest and most sensitive optical image ever taken. Hubble Ultra Deep Field is considered comparable to blue marble, because among the most famous space photographs ever taken. F or one, the atmospheric effect of Twinkle is gone. Secondly, there is noNo background light that would be reflected from the air particles where it disrupts optical images.

Hubble, weighing at 11110 kg (24,250 lb), circles the Earth every 96-97 minutes, orbiting at 7,500 m/s (16,800 mph). The widths of the light bands you can imagine are optical, ultraviolet and almost infrared. For ultraviolet it is a unique telescope, because the UV rays are almost completely blocked by our ozone layer. Although they can cause cancer to human beings, UV rays provide important information about various astronomical objects. Hubble images of the relevant part of the sky and sends information to control centers on the ground through a radio communication with a high bandwidth.

The benefits of space telescopes over ground telescopes were first advanced by Lyman Spitzer in 1946, which is considered a "Father" space telescope.
