Despite being more common than any other planet in our galaxy, the solar system lacks a mini-Neptune. That means, to study these worlds, ...

To test the previous hypothesis that LHS 1140 b is a mini-Neptune, the researchers created a 3D global climate model, or GCM. This used complex math to explore different combinations of factors ...

Mini-Neptune planets are defined as smaller than Neptune, with Enaiposha even smaller. They are relatively straightforward to study because of the thin gaseous layers typically found on these planets.

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

The search for Earth’s twin just got a little closer as astronomers recently presented findings regarding a potential icy or watery “super-Earth” called LHS 1140 b, which is located approximately 49 ...

This brings us to K2-18b, a mini-Neptune orbiting a red dwarf (M dwarf) star about 134 light-years away. The Kepler Space Telescope found it in 2015.

A mini-Neptune, as it sounds, is a gaseous world between the size of Earth and Neptune.A super-Earth, of which astronomers have found many intriguing examples, is a world ranging from some 30 to ...

TIDYE-1b could be mini-Neptune or super-Earth The fortuitous discovery, the researchers said, provides an opportunity for astronomers to learn more about emerging planetary systems and how they ...
