Summary
[edit]DescriptionM100 WFC3 (2018-48-4280).tif |
English: This photogenic celestial object, the magnificent spiral galaxy M100, is seen here as observed with Hubble's Wide Field Camera 3. Hubble's newest camera, it was installed during the last space shuttle servicing mission to Hubble in May 2009, and the M100 photo was taken a few months later. M100 is designated a grand-design spiral galaxy because of its two prominent lanes of young, blue stars. This is caused by ripples of matter in the stellar disk that propagate through the galaxy and create high-density regions of gas. These denser areas precipitate new star formation. In addition, clearly visible are two tightly wound, inner spiral arms wrapping around the core where there is a small bar pattern of stars. The yellowish color of the inner region is from older populations of stars. |

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. |
