The Most Famous Space Telescopes
The Hubble Space Telescope
The Hubble Space Telescope is undoubtedly the most famous of all space telescopes. Launched in 1990, this telescope has revolutionized our understanding of the universe with stunning images of galaxies, nebulae, and stars.
Key Features:
- Uses visible, ultraviolet, and near-infrared light
- Has greatly expanded our understanding of the universe
- Continues to operate more than 30 years after its launch
Chandra X-ray Observatory
Launched into space in 1999, the Chandra X-ray Observatory uses x-rays to observe incredibly hot regions of the universe, such as exploded stars, clusters of galaxies, and matter around black holes.
Important Details:
- Has provided key insights into the high-energy processes of the universe
- Named for Subrahmanyan Chandrasekhar, a Nobel laureate in Physics
Spitzer Space Telescope
The Spitzer Space Telescope, launched in 2003, observes the universe in infrared light, which is often emitted by “cool” objects in space like planets, dust clouds, and distant galaxies.
Significant Features:
- Has studied comets and asteroids within our own solar system
- Has discovered previously unseen details of faraway galaxies
Kepler Space Telescope
Responsible for discovering more than 2,600 confirmed exoplanets, the Kepler Space Telescope significantly advanced our understanding of planetary systems.
Key Achievements:
- Launched in 2009, completed its mission in 2018
- Has discovered a large variety of planet types, from gas giants to rocky, Earth-like planets
James Webb Space Telescope
The much-anticipated James Webb Space Telescope is the successor to Hubble, boasting even more impressive capabilities. Set to launch in 2021, it will observe the universe in infrared light, with a primary focus on the first galaxies to form after the Big Bang.
Exciting Prospects:
- Will study every phase in the history of our universe
- Promises to revolutionize our understanding of the universe
FAQs
What is the purpose of space telescopes?
Space telescopes allow us to observe the universe without the limitations of Earth’s atmosphere, offering clearer, more detailed views of celestial objects and phenomena.
How many space telescopes are there?
There are currently about a dozen active space telescopes, each with its own specific capabilities and areas of focus.
Where do space telescopes get their power?
Space telescopes get their power from the Sun, using solar panels to convert sunlight into electricity.
Remember, the importance of space telescopes lies in their ability to provide a clear view of the universe that is unrivalled by ground-based telescopes. Their findings continue to shape and redefine our understanding of the cosmos.
