TED-Ed: Light waves, visible and invisible - Lucianne Walkowicz
Each kind of light has a unique wavelength, but human eyes can only perceive a tiny slice of the full spectrum -- the very narrow range from red to violet. Microwaves, radio waves, x-rays and more are hiding, invisible, just beyond our...

The Legacy of the Spitzer Space Telescope - SciShow News
On January 30, 2020, we had to say goodbye to NASA’s Spitzer Space Telescope after more thank 16 years of revolutionizing infrared astronomy. Today, SciShow sends it off and says thank you by taking a look back at it’s incredible legacy.
