A new study suggests that spring snowmelt in the Alps is occurring earlier in the year, and the earlier warming – due to climate change – threatens vitally important microbial communities in Alpine soils. Source: https://earthsky.org/earth/alps-climate-change-driven-snowmelt-abrupt-seasonal-change…

‘Earth wind’ may generate water on the moon
Particles carried from Earth’s poles via our planet’s magnetosphere could be interacting with lunar rocks to create small quantities of water on the moon. Source: https://earthsky.org/space/earth-wind-may-generate-water-on-moon…
Can air pollution help us find alien life?
To find alien life in our universe, scientists have considered searches for optical lasers or even giant energy-harvesting structures known as Dyson spheres. Now they’re suggesting a more mundane sort of search, a hunt for air pollution in exoplanet atmospheres. Source: https://earthsky.org/space/can-pollution-help-us-find-alien-life…
To find an extraterrestrial civilization, pollution could be the solution, NASA study suggests
If there’s an advanced extraterrestrial civilization inhabiting a nearby star system, we might be able to detect it using its own atmospheric pollution, according to new NASA research. The study looked at the presence of nitrogen dioxide gas (NO2), which on Earth is produced by burning fossil fuels but can also come from non-industrial sources such as biology, lightning, and volcanoes….
Mars atmosphere shedding charged particles onto Phobos?
New research suggests that particles escaping from Mars’ atmosphere have been accumulating on the surface of the planet’s largest moon Phobos for billions of years. They could provide important new details about the history of both worlds. Source: https://earthsky.org/space/mars-atmosphere-history-phobos-soil…

A robot submarine could explore Titan’s deepest sea
A new study of data from NASA’s bountiful Cassini mission shows that Titan’s largest methane sea, Kraken Mare, is at least 1,000 feet – 300 meters – deep near its center. That’s plenty of room for a future robotic submarine to explore. Source: https://earthsky.org/space/titans-largest-sea-kraken-mare-is-1000-feet-deep…
What’s the weather like on Titan?
Most of the planets in our solar system have some sort of atmosphere and many have dynamic weather systems. But only one moon in the solar system, Saturn’s large moon Titan, can say the same. Source: https://earthsky.org/space/titan-saturns-moon-weather-seasons-methane-rain-storms…
