Ep. 742: Atmospheric Gravity Waves

·58 min·5 clips
Solar eclipses create gravity waves by rapidly cooling the atmosphere, a phenomenon confirmed only recently.
Fraser Cain and Dr. Pamela Gay discuss atmospheric gravity waves, explaining how they form on Earth, Mars, Venus, and beyond, including their role in Martian dust storms and connection to galactic spiral arms. The hosts also touch on political impacts on science funding and share recent astronomy news like solar flare predictions and exoplanet research.

As heard by us

A clear, approachable look at how invisible waves shape planetary skies.

This episode treats gravity waves as the quiet force behind visible patterns in thin planetary atmospheres. It moves from image to mechanism with a steady hand, using Pluto’s haze layers and Mars cloud bands to show how the same physics can read differently from world to world.
