A Beginners Guide To The Hubble Telescope

A beginners guide to Hubble Telescope

For centuries, man has been trying hard to explore the outer space and discover the undiscovered. Hubble is a revolutionary transformer in space technology after the Big Bang Theory.

Since Galileo times, people are trying to see deeper, farther, and more in space. Before space telescopes, people used to discover space from the earth. So, the layer of the earth’s atmosphere was a problem. The sky was not as transparent as it should be. But the Hubble Space Telescope (HST) changed the understanding of the universe. Let’s know more about it.

What Is Hubble?

If I need to describe Hubble in one simple sentence, I will say that the Hubble is just a large telescope in the space. You will wonder to know that its length is more than a large school bus and weight is more than two big and adult elephants.

It is solar-powered and travels about five miles in a second. So, it is able to picture larger areas and faster movements of the universe sharply.


The Hubble was launched on 24th April 1990 into Low Earth Orbit (LEO) and is in operation till the date. However, it is not the first space telescope. The first telescope in the space was Stargazer known as the Orbiting Astronomical Observatory 2 or OAO-2. This achievement was marked on December 7, 1968.

Hubble Space Telescope named after a great astronomer, Edwin Hubble. And it is built by the US and European Space Agency cumulatively. It resides 340 miles above the earth. So, there is no effect of the earth’s atmosphere while observing the sky through it.

Technical Achievements

HST has a long list of achievements because it deepened the understanding of the universe. Since its establishment, more than 4000 astronomers used this to produce thousands of scientific papers. The images captured from Hubble told that the universe is 13 to 14 billion years old and it has mysterious energy. A dark force, dark energy, and black holes that suck everything are the theories produced by HST only.

It also reads all stages of evolution and death of galaxies and stars. That’s why it is also known as a prominent research tool and a PR boon for astronomy. So, you can say that Hubble is not just a telescope, it is more than this.

Instrument of Hubble

It carries more features than a regular telescope in the space. Not only the space telescopes, but it also competes for ground-based much larger telescopes too irrespective of its modest size of 2.4 meters mirror.

The fine guidance sensors and pointing control system helps in moving Hubble in the right direction. On the other hand, the primary and secondary mirrors collect and interpret the light. Various kinds of Cameras and Spectrographs make it able to capture colorful and clear images in the space.

It is known for its incredible productivity using its instruments. Initially, it was expected to live for 15 years in the space. But thanks to its upgradeable system! It still works in an appropriate manner even with little damage.
