Astro-Meteorology and Exoplanet Atmospheric science

We are starting to get data on weather in other exoplanets thanks to JWST and other telescopes, the study of Extraterrestrial atmospheres. Spectroscopic exoplanet atmosphere studies now can search for biosignatures, technosignatures. 

The climate of Mars has allowed Helicopter flights by NASA / JPL

The thick hot toxic air of Venus is the very dense, readings have been taken by Soviet, NASA Magellan and ESA Venus Express probes. It is thought maybe in the future a crewed colony might exist in a cloud village, 30 miles to 33.5 or 50 to 54 km or so above the surface would be the easiest altitude in which to base an exploration or colony.

On Earth we are seeing more high altitude balloon feats, Franky Zapata has became the first person to cross the English Channel from France to England on a flyboard, Europa, Ganymede and Callisto are thought to have no atmosphere but they might have trapped liquids and gasses, Europa is likely to have a sub surface Ocean and HST was able to detect condensed oxygen trapped on the surface of Callisto. At Saturn Enceladus is the sixth-largest moon of Saturn has some trace atmosphere the the Moon has active cryo-volcanism, Enceladus could be 'sampled' without ever having to land. On Titan a Man might also fly in atmosphere of Titan is the dense layer of gases surrounding Titan are suitable for flying. Dragonfly is a planned NASA mission, it will take power from an MMRTG

The four outer planets of the Solar System are gas giants or ice giants of crushing pressures and share a number of atmospheric commonality.

At Neptune there is interest to study the atmosphere and surface of Triton, layers of gases surrounding the Moon like the atmospheres of Titan and Pluto, Miranda at Uranus might have something it speculated that methane, ammonia, carbon monoxide or nitrogen may also exist at concentrations, Titania may have a tenuous seasonal atmosphere of CO2 while at Neptune Triton's atmosphere is composed primarily of nitrogen, with smaller amounts of methane and carbon monoxide.

In September 2023 James Webb telescope studied an ocean world and sees potential signs of alien life in the atmosphere of a distant 'Goldilocks' water world.  NASA's Hubble Space Telescope had detected hydrogen and helium, suggestions of hydrogen cyanide but no water vapor, in the atmosphere of 55 Cancri 'e' Hot water molecules were found in the atmosphere of WASP-39b Sulphur Dioxide has also been fround, WASP-39b's atmospheric transmission spectrum captured by Webb’s Near-Infrared Spectrograph, James Webb Space Telescope detected carbon dioxide and methane in the atmosphere of exoplanet K2-18b Exometeorology will be a extra Solar planet weather report the study of atmospheric conditions of exoplanets

TRAPPIST-1 Outer Planets Likely Have Water
https://www.universetoday.com/166941/tr … ave-water/
The TRAPPIST-1 solar system generated a swell of interest when it was observed several years ago. In 2016, astronomers using the Transiting Planets and Planetesimals Small Telescope (TRAPPIST) at La Silla Observatory in Chile detected two rocky planets orbiting the red dwarf star, which took the name TRAPPIST-1. Then, in 2017, a deeper analysis found another five rocky planets.
It was a remarkable discovery, especially because up to four of them could be the right distance from the star to have liquid water.
The TRAPPIST-1 system still gets a lot of scientific attention. Potential Earth-like planets in a star’s habitable zone are like magnets for planetary scientists.
