The exoplanets belong to a class of worlds called mini-Neptunes, which are smaller and farther from their stars than so-called hot Jupiters, which are easier to spot because they are massive and orbit ...

A newly discovered distant mini-Neptune planet may possess its own atmosphere, ocean, or a combination of the two, even if they don't last for long. The extrasolar planet, or exoplanet, designated ...

The European Space Agency (ESA)’s CHEOPS satellite has discovered four new exoplanets — and they are a hard-to-detect type called a mini-Neptune. These planets are notable because they are the ...

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.

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 ...

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 ...

Mini-Neptunes and super-Earths may have a lot more in common than just being superlatives. Four gaseous exoplanets, each a bit smaller than Neptune, seem to be evolving into super-Earths, rocky worlds ...

A study on the planets titled "Detection of Atmospheric Escape from Four Young Mini Neptunes" has been submitted to the The Astronomical Journal and is awaiting peer review. Researchers from the ...

An enigmatic, cloud-enshrouded planet that has puzzled astronomers for years turns out to be less hot than expected – and surprisingly shiny. That's what the James Webb Space Telescope revealed when ...

"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 ...
