Uranus’s Small Moons Are Dark, Red, and Water-Poor - Eos
…Except for Mab, which is even weirder than expected.

New observations of Uranus’s small inner moons to be presented at #AGU25 reveal that they’re darker, redder, and more water-poor than their larger counterparts. And they’re not always where they should be. 🧪🔭🪐 eos.org/articles/ura...

What’s it like doing fieldwork in Antarctica? 🥶 Sarah Shackleton and @blueicedude.bsky.social from @princeton.edu can answer that.
They just found a 6-million-year-old ice core—a key piece to improve our current climate models!

Glacier Runoff Becomes Less Nutritious as Glaciers Retreat - Eos
Sediment from retreating, land-terminating glaciers contains proportionally fewer micronutrients such as iron and manganese, reducing the glaciers’ value to microorganisms at the base of the food web.
