Chicago gets a rare light show: What made the aurora so spectacular?
Michelle Nichols, Director of Public Observing, The Adler Planetarium, joins John Williams to explain why Chicago recently saw one of the most vivid Aurora Borealis displays in decades. Michelle breaks down how solar flares and coronal mass ejections trigger auroras, why this event reached as far south as El Salvador, and why your phone can detect colors your eyes can’t.
