- A Tour of the Triangulum Galaxy [4K] (youtube.com)
The Milky Way is surrounded by more than 50 near neighbour galaxies that make up the Local Group. The two largest galaxies are us and Andromeda, but we also have an often-overlooked third large galaxy in our neighbourhood- the Triangulum Galaxy. This galaxy is like its own mini-Milky Way, containing stars, clouds, clusters, supernova remnants, and satellites. These are the checkpoints in the Triangulum Galaxy which make up our tour today.
- Project Blue Book (Wikipedia)
Project Blue Book was the code name for the systematic study of unidentified flying objects by the United States Air Force from March 1952 to its termination on December 17, 1969. The project, headquartered at Wright-Patterson Air Force Base, Ohio, was initially directed by Captain Edward J. Ruppelt and followed projects of a similar nature such as Project Sign established in 1947, and Project Grudge in 1949. Project Blue Book had two goals, namely, to determine if UFOs were a threat to national security, and to scientifically analyze UFO-related data.
