Super-Earths and Mini-Neptunes: More Earth-Like Planets May Exist Mar. 11, 2025 — A new study presents a compelling new model for the formation of super-Earths and mini-Neptunes -- planets that ...

NASA has discovered a new world, named Gliese 12 b. It is roughly the size of Earth, lies in the habitable zone, and orbits every 12.8 days.

The two exoplanets, or planets outside of our solar system, orbit a star called TOI-1453, which is slightly cooler and ...

Learn what planet rains molten iron and which planet has two moons like Tatooine in Star Wars.

Astronomers have confirmed the existence of four rocky planets orbiting Barnard’s Star, our nearest solitary stellar neighbor just six light-years away. Using ultra-sensitive instruments, scientists ...

Even more exciting, the model suggests that some Earth-like planets could form in the habitable zone—the region around a star ...

Scientists have discovered four new Earth-like rocky planets orbiting Barnard's Star, just six light-years away. Using advanced technology, these are the smallest exoplanets detected via the ...

Proctor/J. Pollard A quartet of Earth-like worlds, each about 20% to 30% the size of our planet, circle one of our closest stellar neighbors, a new study reveals. The rocky alien worlds are close ...

The discovery of a small protoplanetary disk has implications for the commonality of a particular kind of extrasolar planet, ...

Beyond explaining these observations, the model also allows for predictive analysis of planetary formation and even hints at the potential for other Earth-like planets. Izidoro said although it ...

making it a significant step forward as astronomers search for Earth-mass planets around sun-like stars, Basant said. “A lot of what we do can be incremental, and it’s sometimes hard to see ...
