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 made a significant breakthrough in space exploration by discovering over 6,000 planets outside our solar ...

When astronomers look at planets outside our solar system, called exoplanets, often they have only minimal information they can use to classify them. Two key factors they often do know are the planets ...

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 ...

Of all the potential super-Earths—terrestrial exoplanets more massive than Earth—out there, an exoplanet orbiting a star only 40 light-years away from us in the constellation Cetus might be the most ...

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 ...

"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 ...

Astronomers have spotted two mini-Neptune exoplanets that are losing their puffy atmospheres, in the process possibly transforming into super-Earths. Radiation from the planets' parent stars is ...

Astronomers have identified two different cases of 'mini-Neptune' planets that are losing their puffy atmospheres and likely transforming into super-Earths. Astronomers have identified two different ...

Astronomers have identified two different cases of “mini-Neptune” planets that are losing their puffy atmospheres and likely transforming into super-Earths. “Most astronomers suspected that young, ...
