Summary

DescriptionM100 WFPC1 (2018-48-4279).png	English: This is an image of spiral galaxy M100 taken in 1993 with Hubble's Wide Field/Planetary Camera 1, which was part of an original suite of instruments launched aboard Hubble in 1990. Because of a manufacturing flaw in the primary mirror, which created an optical effect called spherical aberration, the galaxy appears blurred because it cannot be brought into a single focus. In particular, the orange foreground star below image center has tentacle-like image artifacts that are clear evidence of spherical aberration, where the starlight is not concentrated into a single point.

Image title	Over the past 28 years Hubble has photographed innumerable galaxies throughout the universe, near and far. But one especially photogenic galaxy located 55 million light-years away holds a special place in Hubble history. As NASA made plans to correct Hubble's blurry vision in 1993 (due to a manufacturing flaw in its primary mirror) they selected several astronomical objects that Hubble should be aimed at to demonstrate the planned optical fix. The magnificent grand spiral galaxy M100 seemed an ideal target that would just fit inside Hubble's field-of-view. This required that a comparison photo be taken while Hubble was still bleary-eyed. The Wide Field/Planetary Camera 1 was selected for the task. And, the picture had to be taken before astronauts swapped-out the camera with the vision-corrected Wide Field/Planetary Camera 2, in December 1993. Following the servicing mission Hubble re-photographed the galaxy again, and it snapped into crystal clear focus. The public celebrated with Hubble's triumphant return to the clear vision that had been promised. And, jaw-dropping pictures of the vast universe that followed have not disappointed space enthusiasts. Because of the astronaut servicing missions, Hubble's capabilities have only gotten better. To commemorate the 25th anniversary of the first servicing mission, this 2-panel photo compares the blurry, pre-servicing 1993 image to a 2009 image taken with Hubble's newer, Wide Field Camera 3 instrument, installed during the last astronaut servicing mission to the space telescope.
