Astronomers Detect First Known ‘Death Wish’ Planet
- Astronomers identified the first 'planet with a death wish,' HIP 67522 b, which triggers stellar flares that erode its atmosphere, as outlined in a July 2 study.
- Orbiting a 17-million-year-old volatile star at less than 12 times its radius, the planet's close proximity disturbs magnetic fields and triggers intense stellar flares.
- ESA’s Cheops mission observed 15 flares, with most redirected back to HIP 67522 b, exposing it to six times more radiation.
- Ongoing stellar flares are eroding HIP 67522 b's atmosphere, shrinking it from Jupiter to Neptune size over 100 million years, scientists say.
- Beyond this case, ESA’s future Plato mission will study Sun-like stars to capture smaller flares, overturning the assumption that stars act independently in star-planet interactions.

It is the first case of a planet that actively influences its star and that somehow self-damages itself. The Cheops mission of the European Space Agency (Esa) has discovered a planet that could be considered improperly but suggestively self-harmful because it causes its own ruin: it is called Hip 67522 b and orbits so close to the mother star that it induces it to produce violent explosions of energy that end up damaging it by corroding its atmo…
Jupiter or hot and cold Neptunes, rock superlands, ocean planets, lava worlds, ice, or even diamond. Planets spinning around pulsars, or orbiting two stars, or wandering alone in the vast interstellar space... Since in 1995 Michel Mayor and Didier Queloz identified the first exoplanet (51 Pegasi b), astronomers have seen them of all colors and, they thought, in all possible situations. But they were wrong.

The outlook isn’t great for the exoplanet HIP 67522 b. Over the next 100 million years, powerful magnetic fields and destructive cosmic radiation will continue eating away at the distant planet, reducing it from its current Jupiter-sized mass down to a size resembling Neptune. But these apocalyptic conditions aren’t the fault of a nearby black hole. Instead, they’re a result of what astronomers describe as the exoplanet’s “clingy” relationship t…
A recent study published on July 2, 2025 in Nature magazine reports a surprising discovery, a completely new phenomenon, according to researchers. In fact, astronomers have highlighted a particularly conflicting relationship between a suicidal exoplanet and its host star causing a perpetual explosion of the latter. An explosive relationship With the Universe, we are never at the end of our surprises. When we think we are sure of something, an is…
