Long-Forgotten Photographs Reveal Challenger Disaster As It Happened. Michael Hindes of West Springfield, MA, was sorting through boxes of his grandparents' old photographs when he happened upon 26 harrowing photos of the Space Shuttle Challenger Disaster of 1986. To his knowledge, these photos have never been publicly released.
Andromeda is a spiral galaxy close to our Milky Way, and it is the largest galaxy visible to the unaided eye. By using ultraviolet light, astronomers can highlight different structures: blue colours represent light given off by brilliant young stars in the spiral arms, while orange tones are from the older, cooler stars in the galaxy's core. Billions of years from now, the Milky Way and Andromeda will merge. Credit: Galaxy Evolution Explorer Team for NASA / JPL-CalTech.
