As a planetary scientist with a keen interest in the exotic weather phenomena that occur across our solar system, I find the question of what it "rains" on other planets to be a fascinating one. It's important to note that the concept of rain as we understand it on Earth—a liquid water falling from the sky—is not universally applicable to all celestial bodies. The conditions on other planets can lead to precipitation in forms that are quite different from what we're accustomed to.
Let's delve into a few examples of what it might "rain" on some of our neighboring planets and moons, starting with the gas giants Jupiter and Saturn.
**Jupiter and Saturn: Diamonds from the Sky**
The atmospheric data from these gas giants suggest that under certain conditions, it could be raining diamonds. This intriguing phenomenon occurs when lightning storms, similar to those on Earth, electrify the atmosphere. However, instead of water vapor, the storms act upon the methane present in the atmospheres of these planets. The methane is broken down into carbon and hydrogen. Under the immense pressure and high temperatures found in the depths of these gas giants, the carbon atoms have a tendency to bond together. These carbon atoms can then form graphite, and under the right conditions, transform into diamond crystals. These diamonds could potentially sink deep into the planets' interiors, never to be seen again.
Venus: Acid Rain
Moving to our closest neighbor, Venus, the conditions are drastically different. Venus has a thick atmosphere that is primarily composed of carbon dioxide, with clouds of sulfuric acid. The planet experiences extreme greenhouse effects, leading to surface temperatures hot enough to melt lead. It's been observed that it can "rain" sulfuric acid on Venus. However, due to the high temperatures, any acid that does fall quickly evaporates, meaning that there is no accumulation of liquid acid on the surface.
Mars: Dust and Ice
Mars, the red planet, has a thin atmosphere composed mostly of carbon dioxide. While liquid water cannot exist on the surface due to the low pressure and freezing temperatures, Mars is known to experience dust storms, which can be so large that they envelop the entire planet. These storms can lift and transport water ice and dust particles through the atmosphere. When the dust settles, it can deposit a layer of fine, iron oxide-rich dust—hence the red appearance of the planet. Occasionally, Mars experiences sporadic ice precipitation, but it sublimates (turns directly from solid to gas) upon hitting the surface.
Titan: Methane and Hydrocarbon Rain
Saturn's largest moon, Titan, is unique in our solar system for having a thick atmosphere and a cycle somewhat analogous to Earth's water cycle, but with methane and ethane playing the role of water. Titan's atmosphere is rich in nitrogen, and it has clouds that can produce rain in the form of methane and ethane. These hydrocarbons can pool in the moon's low-lying areas, forming lakes and seas. The Cassini-Huygens mission provided us with the first direct evidence of liquid hydrocarbons on another celestial body.
Pluto: Frozen Precipitation
Out in the Kuiper Belt, Pluto offers yet another example of unusual precipitation. With surface temperatures well below freezing, Pluto experiences precipitation in the form of frozen nitrogen, methane, and carbon monoxide. These ices can accumulate on the surface, creating a diverse landscape of icy plains and mountains.
In summary, while the concept of rain can vary greatly from one celestial body to another, it's clear that the universe is full of surprises when it comes to the weather phenomena that can occur. From diamond rains on Jupiter and Saturn to acid rain on Venus, and from the dust storms of Mars to the methane rain of Titan, each planet and moon has its own unique way of experiencing what we might consider precipitation.

Take a look at some of the bizarre "rain" that falls on other planets. On Jupiter and Saturn, it's raining a girl's best friend, according to atmospheric data. Diamonds form when lightning storms turn methane in the planets' atmospheres into carbon, which clumps together, creating graphite.Apr 29, 2015
