Hubble Space Telescope - College Essay

Hubble Space Telescope

The is one of the worlds most powerful earth-orbiting reflecting telescopes. With its capability of producing images from any wavelength, the HST is the eyes of the universe for scientists on earth.
The HST has a capability of operating at any wavelength from a near infrared level to a visible range to an ultraviolet level. Because of this capability, scientists can view toward the outmost reach of the universe. The HST has a 2.4 meter objective mirror and is able to observe different types of wavelengths. Once it locates an image from any wavelength, the HST records the images it receives and then sends the images back to earth by means of radio waves in digital form.
The construction ...

This caused the images to appear as a blur upon use of the telescope. The mirror could not be fixed. So to correct the problem, scientists developed a corrective lens, similar to a contact lens, to compensate for the error. The lens was finally installed in 1993 and compensated exactly for the improper curvature in the primary mirror.
In December 1999, another problem arose with the much needed replacement of gyroscopes and electronics to push the HST to its full capabilities. After its replacement, the HST was back producing stunning images of the universe.
Since the HST launch in 1990, the telescope has been carefully maintained and has been expanding its potential by installations of a near infrared camera, imaging ...
