The discovery overturns traditional models that predicted gas giants in outer orbits and suggests planets can form in gas-poor environments.

Since the 1990s, scientists have discovered approximately 6,100 planets outside our solar system, called exoplanets.

The Panel on Giant Planet Systems is one of six panels providing topical input to the Planetary Science and Astrobiology Decadal Survey Steering Group. This panel will discuss the role played by ...

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 ...

Astronomers have recently tracked a massive rogue planet, referred to as a “super-Jupiter,” that is drifting toward our solar neighborhood. This discovery has captured the attention of the scientific ...

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 ...
