ANECDOTE

Backyard Radio Sparked A New Path

  • Wanda Diaz-Merced heard real-time radio emissions from the sun through a backyard antenna and thought it was horrible noise at first.
  • That moment transformed her: she realized she could still study space by listening instead of seeing.
ANECDOTE

Pigeons, Hiss, And The Big Bang

  • Robert Wilson and his partner heard a persistent hiss in their microwave antenna and ruled out local sources, even pigeons in the dish.
  • That hiss later became the discovery of the cosmic microwave background, evidence for the Big Bang.
INSIGHT

Sound As A Legitimate Data Channel

  • Sonification translates any data into sound to augment human perception beyond sight.
  • It enables detection of patterns that visuals alone can miss.
