Macquarie University astronomers have tracked an extreme planet's orbital decay, confirming it is spiraling toward its star in a cosmic death dance that could end in three possible ways.

A young planet named HIP 67522 causes violent eruptions on its star, dramatically accelerating the loss of its own atmosphere ...

That complexity could mean bigger fireworks ahead. With the sunspot now rotating to face Earth, it could pose a threat for stronger space weather events in the coming days. M-class flares, like those ...

Some exoplanets in their stars' habitable zones may be distinctly uninhabitable due to solar flaring. Red dwarfs are known ...

NASA’s Transiting Exoplanet Survey Satellite (TESS) has made yet another exciting discovery—but it never works alone. Thanks ...

A recent study has uncovered a dramatic interaction between a planet and its parent star that is reshaping our understanding ...

Combined with other high-energy radiation from the star, the flare-induced heating appears to have increased the already steep inflation of the planet's atmosphere, giving HIP 67522 b a diameter ...

Learn about new observations that reveal an exoplanet is destroying itself by cuddling up to its host star, in an ...

A gas giant exoplanet is triggering flares from its host star that will ultimately destroy it, according to European Space Agency research.

Astronomers have spotted an alien planet orbiting so closely to its home star, the planet's magnetic field is triggering massive solar flares to erupt. This is the first time a planet has been seen ...

Astronomers may have uncovered the curious origins of the universe's most curious planets, so-called "double hot Jupiters." The team behind the research hopes their discovery will help find more ...

Long-period giant planets like TOI-4465 b can serve as a bridge between the extreme hot Jupiter exoplanets, which orbit very close to their stars, and the cold gas giants in our own solar system.
