Hubble Space Space telescope Telescope

In summary, the Hubble Space Telescope is a powerful space telescope launched by NASA in 1990 that uses mirrors and instruments to capture light from distant objects in space. It has made groundbreaking discoveries and is expected to continue operating until the mid-2020s when it will be replaced by the James Webb Space Telescope. It can also be seen from Earth with the naked eye when it passes overhead.

Welcome to PF!

With a question so generic, the place to start is wiki or google: http://en.wikipedia.org/wiki/Hubble_Space_Telescope

1. What is the Hubble Space Telescope?

The Hubble Space Telescope is a powerful space telescope launched into orbit by NASA in 1990. It is named after astronomer Edwin Hubble and is known for capturing stunning images of deep space objects and studying the universe.

2. How does the Hubble Space Telescope work?

The Hubble Space Telescope works by using a system of mirrors and instruments to capture light from distant objects in space. The light is then directed to the telescope's cameras and detectors, which produce high-resolution images and data for scientists to study.

3. What has the Hubble Space Telescope discovered?

The Hubble Space Telescope has made numerous groundbreaking discoveries, including the age of the universe, the existence of black holes, and the expansion of the universe. It has also provided images of galaxies, stars, and other celestial objects that have helped scientists better understand our universe.

4. How long will the Hubble Space Telescope continue to operate?

The Hubble Space Telescope was initially designed to last 15 years, but has been continually upgraded and serviced by astronauts. Its current expected lifespan is until the mid-2020s, when it will be replaced by the James Webb Space Telescope.

5. Can the Hubble Space Telescope be seen from Earth?

Yes, the Hubble Space Telescope can be seen from Earth with the naked eye, depending on the time and location. It orbits the Earth at an altitude of about 340 miles, making it visible in the night sky when it passes overhead.
