What is The Hubble Space Telescope? How does it work?

The Hubble Space Telescope: Everything you should know!

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 as both an important research tool and a public relations boon to astronomy.

The Hubble Telescope is named after astronomer Edwin Hubble and is one of NASA’s great observatories, along with the Compton Gamma Ray Observatory (1991–2000), the Chandra X-ray Observatory,

And Spitzer Space Telescope (2003- 2020). The Space Telescope Science Institute (STScI) selects Hubble’s targets and processes the resulting data, while the Goddard Space Flight Center (GSFC) controls the spacecraft.

The famous telescope was named after American astronomer Edwin Hubble, whose observations of variable stars in distant galaxies confirmed that the universe was expanding and gave support to the Big Bang theory.

After a long delay caused by the Challenger disaster in 1986, the Hubble Space Telescope entered orbit aboard the Discovery space shuttle on April 24, 1990.

Since its launch, Hubble has changed our view of space, with scientists basing the telescope’s clear-eyed findings on important items like the age of the universe, giant black holes, or stars in the throes of death.

But thousands of papers have been written. In this article, we’ll talk about how Hubble documented outer space and the instruments that allowed it to do so.

We will also talk about some of the problems that the venerable telescope or spacecraft has faced along the way.

The Hubble Space Telescope Working Explained!

Hubble’s six cameras and sensors see visible, infrared and ultraviolet light. At the center of Hubble is its 8-foot-diameter primary mirror.

The Hubble Telescope is named after the famous late astronomer Edwin Hubble, who has been lauded as the father of modern cosmology and determined the rate of expansion of the universe.

Incoming light hits the primary mirror and is reflected back onto the secondary mirror and through a hole in the primary mirror until it eventually reaches the focal point of the science instruments.

Complicated Path Extends Telescope’s Focal Length When Hubble was first trained on distant celestial targets, astronomers were aware that the images were out of focus.

The primary mirror was based on a wrong prescription. After the astronauts installed corrective optics in 1993, the view was clear.

How did The Hubble Space Telescope get the Name?

Hubble is named after Edwin P. Hubble, an American astronomer. He made important discoveries in the early 1900s. They showed that the Milky Way – the Milky Way – was one of many galaxies containing the Solar System.

His work helped show that the universe was expanding. This gave rise to the Big-Bang theory, which states that the universe began with a rapid burst of energy and has been expanding ever since.

Early instruments on Hubble included the Wide Field Planetary Camera, the Goddard High Resolution Spectrograph (GHRS), the Feint Object Camera (FOC), the Feint Object Spectrograph (FOS), and the High Speed ​​Photometer.

Hubble experienced equipment issues right off the bat. The telescope’s images came back so blurry that they were near useless. Hubble’s main mirror had a defect—a spherical aberration caused by a manufacturing error.

The defect was minute, just 1/50th the thickness of a sheet of paper, but it was large enough to cause major imaging problems.
