Feb. 2, 2024 — Astronomers have shown new atmospheric detail in a set of 15 exoplanets similar to Neptune. While none could support humanity, a better understanding of their behavior might help ...

In our solar system the Earth a rocky terrestrial world and Neptune a gas giant with a hydrogen dominated atmosphere, represent distinctly different types of planets. However, these abundant ...

Scientists are also intrigued by the different cloud structures, which should tell them something novel about the workings of Neptune's atmosphere. Beyond the planet itself are seven of the giant ...

Humanity’s first close-up images from Neptune came 34 years ago from NASA’s Voyager 2 spacecraft. The images shows bright cirrus clouds high in its atmosphere above most of its methane.

It took this image of Neptune and its moon Triton, one of 77 composite photographs that appeared in Otherworlds: Visions of our Solar System, before speeding towards interstellar space. Despite its ...

Planet TOI-3261 b is about twice as dense as Neptune, indicating that the lighter parts of its atmosphere have been stripped away over time, leaving only the heavier components. This shows that ...

In fact, the team calculated that TOI-3261 b is about twice as dense as Neptune, which suggests that the lighter parts of its atmosphere have already been stripped away.

Waterworld: up to 50% of the atmosphere of K2-18b may be composed ... worlds are large planets believed to resemble Jupiter or Neptune Many giant planets have been found orbiting very close ...

Though Neptune is more massive than Uranus, it is smaller in diameter, with a thinner atmosphere, but similarly thick water-rich and hydrocarbon-rich layers. Its rocky core is slightly larger than ...

That puts it in the category of “super-Earth” or “sub-Neptune.” Published this week in Nature, a new paper contains observations that show the exoplanet may sustain a gaseous atmosphere.

Neptune is the furthest planet from the Sun ... But Mercury has almost no atmosphere, so it does not hold onto this heat. The side facing away from the Sun cools down to -180°C at night.

And it's precisely this bizarre atmosphere that's fascinating scientists. A Neptune-like planet with an atmosphere that shouldn't exist Exoplanet LTT9779 b is really close to its star. It is so ...
