In the early days of space travel, two large space telescopes werde installed in Earth's orbit - the Hubble Space Telescope (HST) and the James Webb Space Telescope (JWST). Both telescopes have changed the look of humanity to the universe crucial and made many new discoveries possible. Most important is the HST image of the "Pillars of Creation" in 1995, the "Hubble eXtreme Deep Field" in 2012 and of course the first actual image of an Earthlike Planet by the JWST in 2025.
The human brain produces in 30 seconds as much data as the NASA Hubble Space telescope has produced in its lifetime.

The Hubble Space Telescope (HST) was a space telescope that was launched into low Earth orbit in 1990, and remained in operation until 2018. Although not the first space telescope, Hubble was one of the largest and most versatile, and is well known as both a vital research tool and a public relations boon for astronomy.
The HST is named after the astronomer Edwin Hubble, and has been one of NASA's Great Observatories. With a 2.4-meter (7.9 ft) mirror, Hubble's four main instruments observed in the near ultraviolet, visible, and near infrared spectra. Hubble's orbit outside the distortion of Earth's atmosphere allowed it to take extremely high-resolution images, with substantially lower background light than ground-based telescopes.
Hubble has recorded some of the most detailedvisible-light images ever, allowing a deep view into space and time. Many Hubble observations have led to breakthroughs in astrophysics, such as accurately determining the rate of expansion of the universe.
The HST was built by the United States space agency NASA, with contributions from the European Space Agency. When finally launched in 1990, Hubble's main mirror was found to have been ground incorrectly, compromising the telescope's capabilities. The optics were corrected to their intended quality by a servicing mission in 1993.
After launch by Space Shuttle Discovery in 1990, four subsequent Space Shuttle missions repaired, upgraded, and replaced systems on the telescope. With the end of the Space Shuttle program, further repair missions were no longer possible, but in the meantime earthbound telescopes were equivalent in quality at least in the visible range.
History of the Future
In 2022, the telescope became finally disfunctional and has been destroyed by re-entering the Earth's atmosphere that it couldn't harm TV satellites since their educational programs like "Climbing for Dollars" or shows like "The Running Man" were considered more important for the future of mankind than these eternally boring same images from space :-)
