From counting stars by hand to photographing the deep cosmos

A stellar history of modern astronomy | Emily Levesque · 15:21 · Video: TED · Watch at the source

In short: Astrophysicist Emily Levesque traces the technological evolution of how we capture the night sky, moving from manual star counting to advanced photography.

The video explores the history of astronomical observation and the tools used to document the galaxy. While the technology for photographing the cosmos has changed significantly, Levesque argues that human curiosity remains the driving force behind every celestial discovery.

Levesque, whose research focuses on massive stellar astrophysics and using massive stars as cosmological tools, uses anecdotes to illustrate this journey of discovery.
