Explore the phenomenon and uses of chlorophyll fluorescence, a small amount of light emitted by plants during photosynthesis.

--

In 2009, a satellite circled Earth, scanning and sorting the wavelengths reflecting off the planet’s surface. Researchers noticed something baffling: an unexpected wavelength of unknown origin. They tried looking at Earth with only this wavelength, and saw the planet covered in a red hue of varying intensity. So, what was going on? Zoe Pierrat explores the science of chlorophyll fluorescence.
