Aufeis (Earth sciences 🌍)
Aufeis is a sheet-like mass of layered ice that forms from successive flows of ground or river water during freezing temperatures. This form of ice is also called overflow, icings, or the Russian term, naled. The term "Aufeis" was first used in 1859 by Alexander von […]
The rocket pop ice blender from Rita’s Water Ice tastes exactly like the bottom of a snow cone from the the ice cream truck, and I’m all for it. Plus it comes with edible glitter. Have yourself a magical day. #waterice
6/10 Initial observations reveal 3I/ATLAS is rich in water ice. As it heats up approaching the Sun, it should develop the characteristic coma and tail we associate with comets.
We'll witness billions of years of frozen history awakening to life.

Stunningly detailed ShadowCam image of Shackleton Crater's shadowed rim and floor at the lunar south pole. A single boulder's track is marked by an arrow, revealing recent surface activity. This image, captured by NASA's ShadowCam aboard the Korea Pathfinder Lunar Orbiter (KPLO), showcases the crater's permanently shadowed region, a potential reservoir of water ice. The scale bar indicates 100 meters.

Ice (Glaciology 🗻)
Ice is water that is frozen into a solid state, typically forming at or below temperatures of 0 °C, 32 °F, or 273.15 K. It occurs naturally on Earth, on other planets, in Oort cloud objects, and as interstellar ice. As a naturally […]

Dramatic close-up of the lunar surface near Gassendi crater, at the northern edge of Mare Humorum, taken by the European Southern Observatory's WFI camera. NASA's Lunar Prospector spacecraft is currently orbiting the Moon at a reduced altitude, providing higher resolution data. The image showcases the contrasting terrain and dramatic shadows of the lunar landscape.

Ice divide (Glaciology 🗻)
An ice divide is the boundary on an ice sheet, ice cap or glacier separating opposite flow directions of ice, analogous to a water divide. Ice divides are important for geochronological investigations that use ice cores, since such coring is typically made at highest […]

https://www.science.org/doi/10.1126/sciadv.aao3757 Fig. 1A shows a picture of the Juling crater taken by a camera on the Dawn spacecraft. The image is enhanced to show more details of the ice-rich wall in the shadowed area. Fig. 1B shows the data collected from different locations in that area (from Fig. 1A). It shows the spectra, or patterns of light absorption, which reveal certain features of the surface. The dotted lines are used to show certain ranges where the instrument could create incorrect signals. The absorption bands of water ice are seen at specific points (1.25, 1.5, and 2.0 mm). These are parts of the spectrum where water ice absorbs light. Additionally, there are other smaller absorption bands at 2.7, 3.1, and 3.4 mm, which suggest that minerals like Mg phyllosilicates, NH4 phyllosilicates, and Mg carbonates are also present. These minerals are commonly found on Ceres, a dwarf planet in the asteroid belt.
https://www.science.org/doi/10.1126/sciadv.aao3757 Fig. 2A shows the average light absorption data (spectra) from five different observations of the ice-rich area. These observations were taken from a specific rectangular region of coordinates on Ceres' surface (given by latitude and longitude). It helps scientists study how the surface absorbs light at different points. Fig. 2B focuses on a specific part of the absorption data: the 2.0 mm absorption band. This part is important because it tells us about the presence of water ice. The absorption at 2.0 mm is adjusted or normalized to make it easier to compare with the nearby 1.83 mm point. Fig. 2C shows how the band area (the amount of absorption) at 2.0 mm changes over time. The data is measured in Earth days, with the first observation (L1) set as day 0. This helps track changes in the water ice over time.
https://www.science.org/doi/10.1126/sciadv.aao3757 Fig. 3A shows the comparison between two specific observations (L1 and E1) of the ice-rich area on Ceres. The scientists use the average light absorption data (spectra) from a specific rectangular area, with known coordinates, to compare the two observations. The key point is that both L1 and E1 were observed under the same viewing and lighting conditions, so this comparison is valid. Fig. 3B highlights the differences between the two observations. You can see that the signatures of water ice (the characteristic absorption patterns) and the overall light level (called the continuum) both increased. This suggests that the amount of water ice may have changed between L1 and E1. The error bars show the uncertainty in the data, which includes small measurement errors and possible calibration issues. Fig. 3C compares the data from a test area, which is another region of Ceres, with a different set of coordinates. Unlike the previous comparison, the spectra from this test area don’t show any significant changes, meaning there was no noticeable change in the ice content or conditions over time in this region.
https://www.science.org/doi/10.1126/sciadv.aao3757 Fig. 4A shows how the amount of water ice in the ice-rich wall of Juling crater changes over time. The graph compares two things: 1. The band area at 2.0 mm, which gives an idea of the amount of water ice in the spectra, after removing the signal from the outer regions (areas without ice). This is shown on the left axis. 2. The water ice abundance, which is the percentage of water ice in the area, is calculated using a model. This is shown on the right axis. Both these quantities are tracked over time, measured in Earth days starting from the first observation (L1), and error bars represent the uncertainty in the data. Fig. 4B shows Ceres' orbit and how the solar flux (the amount of sunlight hitting Ceres) changes during the orbit. The part of the orbit that is linked to the Juling observations shows that the solar flux is increasing in Ceres' southern hemisphere, where Juling crater is located. This suggests that as Ceres moves along its orbit, the southern hemisphere is receiving more sunlight, which could influence the amount of water ice present on the surface.
