Misaligned Exoplanet Is Challenging How We Think Solar Systems Form

Astronomers studying the dwarf-star system TOI-3884b have uncovered a striking anomaly: the planet’s orbit is sharply misaligned with its star’s rotation. Using multicolour transit observations, researchers detected repeated starspot-crossing events that revealed the planet passes over cooler regions on the stellar surface. Follow-up monitoring showed the star rot...

James Webb Space Telescope Spots an Exoplanet Losing Its Atmosphere in a Huge Helium Stream

Astronomers using NASA’s James Webb Space Telescope have observed a massive helium cloud escaping from the super-puff exoplanet WASP-107b, marking the first direct detection of such atmospheric loss. Webb’s infrared data reveal an enormous exosphere nearly ten times the planet’s radius, with helium streaming both ahead of and behind the planet in its orbit. The ...
