The outlook isn’t great for the exoplanet HIP 67522 b. HIP 67522 is also a far more active star than our sun, and routinely emits much stronger energy flares. Knowing this, Ilin’s team decided to try getting a closer look at HIP 67522 b, and enlisted the European Space Agency’s (ESA) exoplanet satellite CHEOPS, for help. Being bombarded with so much high-energy radiation does not bode well for HIP 67522 b. In the next 100 million years, HIP 67522 b could go from an almost Jupiter-sized planet to a much smaller Neptune-sized planet.
