Indigenous Astronomy, Auroras, Inclusive Science. Dec 25, 2020, Part 2

Nature’s Own Holiday Light Show The spectacular glowing green of the Northern Lights is caused by charged particles from the solar wind interacting with gas molecules, atoms, and ions in the atmosphere. Protons and electrons streaming from the sun follow the Earth’s magnetic field lines, accelerating down towards the poles. The aurora process is similar to a neon sign—the charged particles excite atmospheric gas, causing it to emit light.  Don Hampton, research associate professor in the Geophysical Institute of the University of Alaska in Fairbanks, explains how the aurora borealis forms, what accounts for its typical green glow, and offers tips for snapping a photo of the lights should you be lucky enough to catch a glimpse of this astronomical light show.   Relearning The Star Stories Of Indigenous People In 2012, the Obama administration projected that the United States would need to add an additional 1 million college graduates in STEM fields per year for the next ten years to keep up with projected growth in the need for science and technology expertise. At the same time, though, native Americans and other Indigenous groups are underrepresented in the sciences, making up only 0.2% of the STEM workforce in 2014, despite being 2% of the total population of the United States. Why are Indigenous people still underrepresented in science? Ira speaks with astrophysicist Annette Lee and anthropologist Kim TallBear about the historical role of science and observation in Indigenous communities, and how Western scientific culture can leave out other voices. They also discuss the solutions: What does an inclusive scientific enterprise look like, and how could we get there? Subscribe to this podcast.
