The Surprising Ways Art Has Advanced Astronomy


  • Astronomy and art have been inseparable for centuries.

  • In the era before digital CCD cameras and their predecessors, photographic plates, astronomers were required to be artists.

  • Today, whenever an image is taken of the cosmos, it's initially a monochromatic freeze-frame, and it takes careful layering and palette selection to bring images like the Pillars of Creation to life.

  • Drawing on principles from art to create scientific visualizations, astronomers are able to see their work with a new perspective and, perhaps more crucially, share their discoveries with other scientists more clearly than with traditional techniques.


  • Pillars of Creation is a photograph taken by the Hubble Space Telescope.
