A year that is a mere 18 hours TOI 849 b is an extremely unusual planet in the so-called “Neptune Desert” – a term used by astronomers for a region close to stars where we rarely see planets of ...

Our solar system is a smashing success. A new study suggests that from its earliest period — even before the last of its nebular gas had been consumed — Earth’s solar system and its planets looked ...

In this research area we investigate everything from the earliest formation of planets via dynamic collisions, to the atmospheres and characteristics of solar system planets and exoplanets. Exoplanet ...

A newly discovered planet has the diameter of Jupiter but eight times its mass, giving it twice the density of Earth despite being composed mostly of gas. Not only have these characteristics of this ...

A new NASA study reveals a surprising way planetary cores may have formed—one that could reshape how scientists understand the early evolution of rocky planets like Mars. Conducted by a team of ...

A recent astronomical discovery has shaken long-held beliefs about how planets form. For decades, scientists thought that stars much smaller than our Sun couldn't form giant planets. That theory just ...

Rocky planets such as Earth and Mars are born when small particles smash together to form larger, planet-sized clusters in a planet-forming disk, but researchers are less sure about how gas-giant ...
