The second reason is spectral coverage. The Hubble has sensors that cover from the IR into the UV so can get a much better picture of the universe and many processes radiate in the IR and UV.

WebOnce it had been identified in 1990 that the primary mirror in the recently launched Hubble Space Telescope (HST) was defective due to it having been ground to the wrong shape, engineers at NASA came under immense pressure to fix the problem. Web19 feb. 2008 · Astronomers using Hubble have compiled a large catalogue of gravitational lenses in the distant universe, finding 67 galaxies lensed by massive elliptical and lenticular-shaped galaxies. If this is representative, there might be nearly 500 000 similar gravitational lenses in total over the whole sky. martin money saving expert competitions

Web1 mrt. 2024 · Catadioptric telescopes are excellent for planetary observation and imaging as they provide a slow focal ratio that is necessary to see more planetary details within the narrow field of view at higher magnification. Focal ratios slower than f/10 will be better suited to seeing planets. Web26 jun. 2024 · On June 24, 1990, Hubble full-out failed a focusing test. Its secondary mirror, meant to focus incoming light, didn’t seem to be behaving as it should. Even Hubble’s best shots were strangely... martin money credit card
