longacre writes "An amateur video of the 1986 Space Shuttle Challenger explosion has been made public for the first time. The Florida man who filmed it from his front yard on his new Betamax camcorder turned the tape over to an educational organization a week before he died this past December. The Space Exploration Archive has since published the video into the public domain in time for the 24th anniversary of the catastrophe. Despite being shot from about 70 miles from Cape Canaveral, the shuttle and the explosion can be seen quite clearly. It is unclear why he never shared the footage with NASA or the media. NASA officials say they were not aware of the video, but are interested in examining it now that it has been made available."

Scientists plan to test whether sharks enjoy listening to Christmas pop songs, after US research showed fish could recognize melody. Chris Brown, senior marine biologist at the Loch Lomond aquarium, said seasonal music would be played through walkthrough underwater tunnels where they can be heard by dozens of nurse sharks, black-tip reef sharks, and ray species. Experts will then monitor the sharks' reactions to different songs. We'll play everything from Kim Wilde and Mel Smith's Rocking Around the Christmas Tree and Merry Christmas Everybody by Slade to Wham's Last Christmas. We may find they prefer something softer like White Christmas by Bing Crosby," Brown said. Thank you for answering this question science.
