Astronomers have discovered four worlds unlike anything in our own solar system that provide a "missing link" between Earth twins and Neptune-like planets, they say. Scientists are interested in mini ...

What is the weather forecast like for the Milky Way's most common planets? Cloudy or clear? New research aims to discover if so-called "mini-Neptunes" — which are smaller than the solar system ice ...

Exoplanets come in shapes and sizes that are not found in our solar system. These include small gaseous planets called mini-Neptunes and rocky planets several times Earth’s mass called super-Earths.

A strange planet that's stymied astronomers for years has an "unusually shiny atmosphere" and could be home to large amounts of water vapor, scientists said in a study published Wednesday in the ...

Astronomers have recently unveiled an extraordinary discovery in the cosmos: a new exoplanet named Enaiposha, located 47 light-years from our solar system. Initially thought to be a mini-Neptune, this ...

For decades, astronomers have classified exoplanets into neat categories: rocky Earth-like planets, gas giants like Jupiter, ...

NASA's prolific Kepler space telescope, which shut its powerful eye nearly five years ago, continued finding exoplanets even while taking its final breaths. A team of astrophysicists and citizen ...

In a significant scientific breakthrough, a team of researchers has gained remarkable insights into the enigmatic atmosphere of a celestial body known as a "mini-Neptune." These types of planets are ...

Six exoplanets with sizes between Earth and Neptune have been in rhythm with each other since they were born around the same star 4 billion years ago, new research suggests. When you purchase through ...

A four-planet system observed several years ago by the Kepler spacecraft is actually a rarity: Its planets, all miniature Neptunes nestled close to the star, are orbiting in a unique resonance that ...

"We want to comprehend the behaviors of these planets, given that those slightly larger than Earth and smaller than Neptune are the most common in the galaxy." When you purchase through links on our ...
