The gas giant K2-132b expands as its host star evolves into a red giant. The energy from the host star is transferred from the planet’s surface to its deep interior, causing turbulence and deep mixing in the planetary atmosphere. The planet orbits its star every 9 days and is located about 2,000 light years away from us in the constellation Virgo. Upper left: schematic of the K2-132 system on the main sequence. Lower left: schematic of the K2-132 system now. The host star has become redder and larger, irradiating the planet more and thus causing it to expand.
