Fascinating! See what your vocal cords (or larynx) look like when you’re speaking or making sounds. Your larynx is where pitch (musical tones) and volume are controlled. You can also make it louder or more quiet depending on how much air is being pushed out through your lungs!

This is footage from a video laryngoscopy — larynx or voicebox + scope: 

From the University of Iowa Hospitals and Clinics (with permission). This is what happens when I say “eee” with a camera down my throat… Note also that the trachea is visible when I breathe. Cool huh? Actual size: roughly that of a quarter.

Astrophysicist Dr. Neil DeGrasse Tyson was asked by a reader of TIME magazine, “What is the most astounding fact you can share with us about the Universe?” This is his answer.

We’re pretty addicted to these educational/inspirational videos about the universe, atoms, the elements, and the origins of life… This fan-made one features a portion of Dr. Tyson’s interview “10 questions for Neil deGrasse Tyson” for TIME Magazine in 2008, also a great video to watch.
