Question

The Hubble space telescope is designed with ------hyperbolic mirrors known for good imaging performance over a wide field of view.
A) Two
B) Four
C) Three
D) Many

Answer 1

Hint: Hubble telescopes are the most professional telescopes. The Hubble telescope was designed with two hyperbolic mirrors. These mirrors must be polished to an accuracy of 10 nanometres for covering a wide range of areas for better imaging. Let’s discuss the design of the telescope to determine the number of mirrors used.

Complete step by step solution:
Let’s discuss about the Hubble Telescope in great detail:
The Hubble Telescope is the largest telescope in space Hubble revolves around earth at about 5 miles per second. The Hubble Telescope faces towards space and takes pictures of planets, stars and galaxies. Hubble used to capture the image of a star being born and dying. It has made us see galaxies that are trillion of miles far away from us.

Hubble is unlike other telescopes which we used on earth to see objects through our eyes but it flies around orbits high above the earth and its atmosphere and takes pictures of the galaxies and solar system like our mobile phones.

Till now Hubble has made scientists discover and learn about new galaxies which are far away from our galaxy, solar system, moon and Pluto which was never done before. Hubble has spotted black holes also. This is the reason Hubble Telescope uses Two Hyperbolic mirrors. A curved mirror used is the primary mirror for taking pictures and the second one modifies the optical characteristics for visual observation.

Thus option (A) is correct.

Note: Name of the Hubble Telescope was made after Edwin P. Hubble, who was an astronomer. In 2009 scientists went into the space to put new cameras in the Telescope for its better working; which helps Telescope to continue taking beautiful pictures. At present Hubble Telescope is 30 years old.
