Astronomers have discovered a young exoplanet, HIP 67522 b, that is triggering powerful flares on its host star, causing its atmosphere to erode rapidly. This interaction is expected to shrink the planet significantly over the next 100 million years.

Why it matters: The planet-star magnetic interaction is a newly observed phenomenon that dramatically impacts planetary evolution.

The big picture: HIP 67522 b’s atmospheric loss could transform it from a Jupiter-sized gas giant to a smaller Neptune-like planet.

Stunning stat: The planet experiences six times more radiation than if it orbited at a safer distance.

Commenters say: Many express fascination with the unique star-planet magnetic dynamics, while some ponder implications for other young exoplanets’ survival.
