As someone who has always had an interest in space and the mysteries beyond our planet, the Hubble Space Telescope has always been a fascinating subject to me. The Hubble Telescope is one of the most important tools that humanity has ever developed for exploring the universe. In this article, we will explore the history of the Hubble, how it works, its major discoveries, and its impact on astronomy and the public's understanding of the cosmos.
Introduction to the Hubble Space Telescope
The Hubble Space Telescope is a sophisticated piece of technology that has been orbiting Earth since 1990. It was named after Edwin Hubble, a famous astronomer, and was launched into space by NASA and the European Space Agency. The telescope is 347 miles above Earth's surface and travels around the planet every 97 minutes. Its mirror is 2.4 meters (7.9 feet) in diameter, which allows it to capture high-resolution images of distant galaxies, stars, and planets. The telescope is also equipped with various instruments that allow scientists to study celestial objects' composition, temperature, and other important characteristics.
History of the Hubble Space Telescope
The idea of a space telescope was first proposed in the 1940s, but it was in the 1970s that the project gained momentum. NASA began developing the Hubble Space Telescope in the late 1970s, and it was finally launched into space in 1990 after several delays.
The launch of the Hubble Space Telescope was a historic moment for astronomy. The telescope allowed scientists to study the universe in previously impossible ways. It has been used to discover new planets, study the formation of galaxies, and explore the mysteries of dark matter and energy.
How the Hubble Space Telescope Works
The Hubble Telescope works by capturing light from distant objects in the universe. The light enters the telescope through its mirror and is focused onto a camera or other instruments. The telescope's instruments then analyse the light to determine its composition, temperature, and other properties.
It is also equipped with a system that allows it to adjust its focus and position. This is important because it allows scientists to take clear images of objects millions of miles away. The telescope's ability to adjust its position allows it to observe objects at different angles, providing valuable information about their structure and composition.
Hubble's Major Discoveries
The Hubble Space Telescope has made many important discoveries since its launch into space. Some of its most significant discoveries include:
The Age of the Universe
One of the Hubble Telescope's most important discoveries was the age of the universe. By studying the light from distant galaxies, astronomers were able to determine that the universe is approximately 13.8 billion years old.
Dark Matter and Dark Energy
The Hubble Telescope has also been used to study dark matter and dark energy, two of the most mysterious substances in the universe. These substances cannot be directly observed, but their effects can be detected through their gravitational influence on other objects in the universe.
Exoplanets
The Hubble Telescope has also been used to discover exoplanets, planets that orbit other stars. By studying the light from these planets, scientists have been able to determine their composition and other important characteristics.

The Impact of the Hubble Space Telescope on Astronomy
The Hubble Space Telescope has had a profound impact on astronomy. It has allowed scientists to study the universe in unprecedented detail and has led to many important discoveries. The telescope has also inspired a new generation of astronomers and space enthusiasts and played a key role in shaping our understanding of the universe.
Hubble's Latest Mission and Future Plans
The Telescope is still operating today, and NASA plans to continue using the telescope for many years. In 2021, a new mission called the Hubble Legacy Field was launched. This mission will use the telescope to study a region of the sky that the telescope has already observed.
Hubble versus Other Space Telescopes
It is not the only space telescope in operation. Several other telescopes are currently in use or under development, including the James Webb Space Telescope, the Chandra X-ray Observatory, and the Spitzer Space Telescope.
Each of these telescopes has its own strengths and weaknesses. Chandra X-ray Observatory is designed to observe X-rays from celestial objects.
