SHAPIRO: Diaz-Merced misplaced her imaginative and prescient when she was in her early 20s, so she determined to dedicate her profession to sonification – a way that emerged within the late 1800s however had since been deserted in mainstream astronomy analysis.

CHANG: She and a colleague developed a prototype for LightSound seven years in the past. And for this week’s eclipse, greater than 750 of those gadgets had been despatched out free of charge to observe events throughout the trail of totality.

DIAZ-MERCED: When it is detecting brightness, you hear tones – increased tones or decrease tones relying on how vivid. And from the solar, what you hear is ticking sounds.
