The Planetary Health Check is a key monitor of earth's vital signs—and will guide action for a more sustainable world.

It provides a dynamic, time-resolved view of planetary transformation, a missing link between young inflated worlds and the compact sub-Neptunes that populate the galaxy.

About 4.6 billion years ago, a celestial cloud collapsed, paving the way for our solar system to form. Then, a nebula with strong gravitational pull took shape, kick-starting the birth of the sun. But ...

Rocky planets like our Earth may be far more common than previously thought, according to new research published in the journal Science Advances. It suggests that when our solar system formed, a ...

Six planets are set to align on Saturday, creating a planetary parade that will be visible to sky-gazers across the globe.

A new study has proposed the existence of Planet Y, an alternative Planet Nine candidate that is smaller and closer to Earth than the hypothetical Planet X, which astronomers have been hunting for ...

Scientists may finally have an answer for why the ferocious jet streams on the solar system’s giant planets blow in opposite directions — eastward on gas giants Jupiter and Saturn, and westward on ice ...

Spectacular clouds swirl across the surface of Jupiter. These clouds contain water, just like Earth's, but are much denser on the gas giant—so thick that no spacecraft has been able to measure exactly ...

A network of powerful ground-based telescopes captured rare starspot-crossing events on TOI-3884b, revealing cooler patches on the star’s surface and rapid changes tied to its rotation. By combining ...
