Night Launch of Endeavour
Explanation: Space Shuttle Endeavour thunders off into orbit in a rare night launch. This March 1995 mission is most famous for operating the set of astronomical telescopes known as Astro-2 . Astro-2's telescopes observed the universe in ultraviolet light - light so blue humans by themselves can't see it. Astro-2 measured the amount of ultraviolet light emitted by several interesting stars , galaxies , planets, and QSOs . Analysis of data from this NASA mission has yielded the first clear detection of helium created during the beginning of the universe.
