The story of Cygnus the Swan constellation, from Greek mythology: Phaeton, unable to control the chariot of the sun, careens wildly though the heavens, scorching the earth. The god Zeus strikes the impetuous charioteer with a bolt of lightning, causing him to fall headlong into the river. His close friend, Cygnus, implores Zeus for help. Zeus transforms Cygnus into a swan so he can dive deeply. Then to honor this final act of service, Zeus fixes the image of Cygnus in the heavens. Learn more at BirdNote.org.
