Hubble was launched by the Discovery Shuttle, flight no. STS-31. It launched on 24 April 1990, 12:33:51 UTC.
The Hubble Space Telescope has a number of instruments, but the primary one is an optical telescope.
Space Shuttle Discovery, mission STS-31.
No, there's a great number of highly specialized telescopes in orbit. The most famous ones apart from Hubble are the Spitzer Space Telescope (for infrared) and the Chandra (for X-rays).
That number is in the neighborhood of 132,360,000,000,000,000,000,000,000 . (rounded to the nearest sextillion meters)
No, Hubble Space Telescope uses a variety of wavelengths to observe the universe, including ultraviolet, visible, and near-infrared light. This allows it to capture a wide range of astronomical phenomena and provide a more comprehensive understanding of the cosmos.
There are a number of differences. First, they are in different orbits; the Hubble is higher than the ISS. The ISS is a lot bigger. Probably the most important difference is that the Hubble has a big telescope but no people, while the ISS has people but no big telescope.
They are literally "uncountable"; every time we improve the telescope, we see more and more galaxies.
Hubble was launched into space on April 24, 1990, at 8:33 a.m. EDT on board of the space shuttle Discovery with flight number STS-31.
NASA and the ESA have collaborated on a number of projects including SOHO, Ulysses, the Hubble Space Telescope, and the Cassini-Huygens space probe. Recently, they were involved in the installation of the ESA Columbus module as part of the International Space Station.
There was not one specific day, nor one specific person -- rather, like most scientific inventions, it was a process that took some time and involved a number of scientists and researchers. Named after astronomer Edwin P. Hubble, the project was a collaboration between NASA (the National Aeronautics and Space Administration) and several other organizations, including the European Space Agency. The research and experimentation for creating this kind of space telescope began in 1946, and continued throughout the 1960s. But it wasn't until the late 1970s that the Hubble project was funded by congress. After numerous problems and delays, the Hubble telescope was finally launched in 1990, with some needed fixes made to it by American astronauts in late 1993.
There are a number of websites where one can find free pictures of the stars. One may wish to visit the websites Hubble Site, Space Telescope, and Universe Today.
