Something to enthuse your students about how fantastic chemistry can be. This 7 minute video produced by NASA is well worth watching and showing to all your students, particularly when you are covering Topics 11 and 21.

  Discovery of SO₂ in an exoplanet's atmosphere

It really illustrates the excitement of discovery shown by an international group of young researchers and how well they work together as a team. It also explains the chemistry behind the use of spectrometry on the James Webb Space Telescope which led them to the unexpected discovery of sulfur dioxide in the atmosphere of the exoplanet orbiting the star WASP-39, some 700 light years away from Earth.
