How Did the Earth and Moon Form: UChicago Explainer Series The Earth formed over 4.6 billion years ago out of a mixture of dust and gas around the young sun. It grew larger thanks to countless collisions between dust particles, asteroids, and other growing planets, including one last giant impact that threw enough rock, gas, and dust into space to form the moon.

What is Perfect Pitch? University of Chicago Explainer Series Perfect pitch refers to a person’s ability to identify any musical note by name after hearing it, without reference to other notes. Perfect pitch—also known more technically as absolute pitch—can also refer to the ability that some singers have to sing a given note on cue. Though perfect pitch was thought to be a rare ability that depended primarily on early musical training in a “critical period” of sensitivity in childhood, auditory learning studies at the University of Chicago and elsewhere have shown that some individuals can learn to identify musical notes by ear even later in life.
