The Cosmos is full of mysteries. Many of those mysteries are not visible to the human eye. NASA’s Fermi Gamma-Ray Telescope is one of the may telescopes finding hundreds of new objects at the very edge of the electromagnetic spectrum. Many of them have one thing in common: Astronomers have no idea what they are.
This ScienceCasts episode by NASA from 2012 explores the groundbreaking research done at these wavelengths, including a complete map of the universe at the very edge of the electromagnetic spectrum.
Just imagine what else lies even beyond that spectrum!
