The Hubble Space Telescope is a powerful astronomical instrument that orbits the Earth and captures stunning images of the universe. It has been operational since 1990 and has helped astronomers make groundbreaking discoveries about our galaxy and beyond. The telescope’s advanced technology allows it to observe distant stars, galaxies, and other celestial objects that cannot be seen with ground-based telescopes. In this article, we will delve into the history and capabilities of the Hubble Space Telescope.
The Hubble Space Telescope: A Brief History
The Hubble Space Telescope (HST) is one of the most significant astronomical instruments ever built. It was named after Edwin Hubble, an American astronomer who played a crucial role in the study of galaxies. The HST was launched into space in 1990 and has been in operation ever since. The telescope is operated by NASA and the European Space Agency (ESA) and has contributed significantly to our understanding of the universe.
The Hubble Space Telescope: How It Works
The Hubble Space Telescope is located in low Earth orbit, approximately 340 miles above the Earth’s surface. The telescope is designed to capture images and data from the universe in visible, ultraviolet, and infrared light. The telescope’s primary mirror is 2.4 meters in diameter, and its instruments can observe objects up to 13.3 billion light-years away.
The telescope is equipped with several instruments that allow it to capture images and data from the universe. These include the Wide Field Camera 3, the Cosmic Origins Spectrograph, and the Advanced Camera for Surveys. The HST operates using solar panels to generate power and thrusters to position itself for observations.
One key takeaway from understanding the Hubble Space Telescope is its significant impact on astronomy. The telescope has contributed to our understanding of the universe’s origins, evolution, and structure, leading to new discoveries and advancements in technology. The incredible images captured by the telescope have also inspired public interest in astronomy and education. As the HST nears the end of its operational life, its successor, the James Webb Space Telescope, will continue to build on its legacy with new capabilities for observing the universe.
The Hubble Space Telescope: Discoveries
The Hubble Space Telescope has made numerous discoveries since its launch. Some of the most significant discoveries include the confirmation of the existence of dark energy, the discovery of supermassive black holes at the center of galaxies, and the measurement of the expansion rate of the universe.
The telescope has also captured stunning images of the universe, including galaxies, nebulae, and star clusters. The images have contributed significantly to our understanding of the universe’s structure and evolution.
The Hubble Space Telescope has played a crucial role in advancing our understanding of the universe since its launch in 1990. Its significant contributions to cosmology by providing evidence for the Big Bang theory, dark matter, and dark energy have paved the way for further research. The telescope’s observations of stars and galaxies have also provided insights into their evolution, structure, and physical processes. Although the HST is approaching the end of its operational life, the development of the James Webb Space Telescope will continue to push the boundaries of astronomy into the future.

Contributions to Cosmology
The Hubble Space Telescope has made significant contributions to cosmology, the study of the universe’s structure and evolution. The telescope’s observations have provided evidence for the Big Bang theory, the most widely accepted explanation of the universe’s origins. The HST has also contributed to the understanding of dark matter and dark energy, two mysterious components of the universe that make up the majority of its mass and energy.
Contributions to Stellar Evolution
The Hubble Space Telescope has also contributed to the understanding of stellar evolution, the study of how stars form, evolve, and die. The telescope has captured images of stars at various stages of their lives, from protostars to supernovae. The images have provided insights into the physical processes that govern star formation and evolution.
The Future of the Hubble Space Telescope
The Hubble Space Telescope has been in operation for over 30 years and has made significant contributions to astronomy. However, the telescope is nearing the end of its operational life. NASA and ESA are currently working on the James Webb Space Telescope, a successor to the HST. The JWST is scheduled to launch in 2021 and will be capable of observing the universe in infrared light.
FAQs: What’s the Hubble Space Telescope
What is the Hubble Space Telescope?
The Hubble Space Telescope is a space telescope launched into low Earth orbit in 1990. It is named after astronomer Edwin Hubble and is one of NASA’s Great Observatories. The Hubble is a joint project of NASA and the European Space Agency (ESA) and is used to observe distant galaxies, stars, planets, and other celestial objects.
What has the Hubble Space Telescope discovered?
The Hubble Space Telescope has made countless discoveries since its launch in 1990. Some of its most notable discoveries include the confirmation of the existence of dark energy, the discovery of the first organic molecule on an extrasolar planet, and the observation of galaxies in the early universe to better understand how they form and evolve. The Hubble has also captured stunning images of nebulae, galaxies, and other celestial objects that have inspired public interest in space exploration and astronomy.
How does the Hubble Space Telescope work?
The Hubble is a reflecting telescope, meaning it uses mirrors to gather and focus light from distant objects. It has a primary mirror that is 2.4 meters (7.9 feet) in diameter and several smaller mirrors that correct for optical aberrations. The telescope’s instruments are designed to detect different wavelengths of light, from ultraviolet to near-infrared, and it can observe objects up to 13.4 billion light-years away.
How long will the Hubble Space Telescope last?
The Hubble Space Telescope was designed to operate for 15 years, but it has been in operation for over three decades. NASA and ESA have worked together to upgrade and repair the telescope throughout its lifetime, with five servicing missions taking place between 1993 and 2009. Currently, the plan is to keep the Hubble in operation until at least 2030, when it will be replaced by the James Webb Space Telescope.
What impact has the Hubble Space Telescope had on astronomy?
The Hubble Space Telescope has had a significant impact on astronomy by providing scientists with a more comprehensive understanding of the universe. Its observations have led to the development of new theories in astrophysics, and its images have inspired a new generation of space enthusiasts.
