All You Need To Know About Hubble Space Telescope


Hubble Space Telescope is quite a recent discovery but around 200 years ago, humans used to predict facts about the space and the universe by all that was visible through the naked eye. This pattern changed only when Galileo invented the first powerful space telescope in 1610. This was the beginning of a new revolution in astronomical discoveries.

It was later revealed that Saturn from the solar system has rings of gas and Jupiter had more than one moon. Many interesting scientific discoveries took place after the invention of telescopes. It was earlier believed that the Milky patch in the sky was a cloud of gas. But later, it was discovered that it was our galaxy containing billions of stars.

After the invention of the first telescope, scientists kept on inventing newer and more powerful ones. These telescopes were placed in areas that did not have the hustle and bustle of city life.

Who Discovered Hubble Space Telescope?

Edwin Hubble, after which the telescope is named discovered it. But before he invented the Hubble Space Telescope, he used the telescope present in the Mt. Wilson Observatory next to the Pasadena, California in the 1920s. He used those old telescopes in those days to discover other galaxies apart from our own.

What Is So Special About The Hubble Space Telescope?

Hubble is the first-of-its-kind huge telescope kept in space. This optical telescope is not affected by atmospheric distortion, pollution or rain clouds. The Hubble Space Telescope gives one an unobstructed view of the space. Until now, it has been used to get images of distant stars and other galaxies.

It was deployed into space in April 1990. It was the first major advancement in telescopes after Galileo’s invention. Moreover, this tool has been in operation for 25 years and has been through 5 servicing missions. Owing to this giant tool, humans have got a better view, idea, and understanding of the space and universe.

Interesting Tidbits On The Hubble Space Telescope

  • Since 1990, the telescope has made more than 1.3 million observations.
  • The data given by the telescope has helped in publishing more than 15,000 papers on space studies. These findings have been used further in researches and other findings of space.
  • The Hubble telescope does not travel into space like other satellites but takes pictures of the galaxies, planets, and stars while orbiting around our Earth. Its current speed is 17,000 mph.
  • Interestingly, the telescope has no thrusters to change its angles, instead, it works on Newton’s third law and changes its course by spinning in the opposite direction.
  • Out in the space, it can view celestial bodies and other astronomical objects with an angular size of 0.05 arcseconds.
  • Furthermore, it has an amazing combination of detectors and optics that can help it to spot a night light on our Earth right from the moon.
  • Its size from its launch date to now has considerably increased by 3,000 pounds. It weighed 24,000 pounds when it was launched.
  • It is 43.5 ft long.
