![]() ![]() While Hubble was not returning the image quality expected, it was still providing results that were impossible for ground-based telescopes, with high resolution and spectra that led to new research. Less than two months later, STScI convened an expert workshop on the issue. STScI staff and their partners at NASA immediately began experimenting with algorithms to resolve and make use of Hubble’s data and imagery, pushing forward image processing technology. The flaw scattered the light reflected by cosmic objects, resulting in fuzzy images. An investigation revealed that during its manufacture, the outer edge of the mirror was ground too flat by a depth of 4 microns (roughly equal to one-50th the thickness of a human hair). ![]() ![]()
