Icy Ocean Planet Research: NASA ROSES-25 Amendment 71: New Opportunity A.16 Cryosphere
[NASA]. A.16 Cryosphere solicits high-impact efforts focused on sea ice, ice sheets, and glaciers. The expectation is that proposed investigations will use the wealth of data from NASA satellites and […]
![Occam’s razor-based deconvolution result of the subset of signals associated with CnHmN parent and fragment species detected by the DFMS on 3 August 2015. The measured signals (measured) are given in arbitrary units (a. u.) with 30 % error margins. The different contributions of the chosen candidate molecules are colour-coded according to their molecular structure – in shades of red and purple for chain-based molecules and in shades of green and blue for cyclic molecules. -- [astro-ph.EP]](https://i0.wp.com/astrobiology.com/wp-content/uploads/2026/08/Nitrogen.png?resize=1200%2C707&ssl=1)

The Role of Disruptive Impacts on Ocean Generation and Longevity in Icy Moons
[Nature Astronomy] Among icy moons of the outer Solar System, subsurface water oceans and large collisions both seem to be common, but the impact of the latter on the presence […]
![(Top) Measured OC albedo values from Goldstone (from Table 4) and (bottom) measured OC albedo values from the GBT (from Table 5). The horizontal dashed lines indicate the weighted means of the albedos, which is 0.90 for Goldstone and 0.80 for GBT. The error bars on our albedo values are taken to be the total uncertainty calculated in Section 4. The color bar on the right shows the dates of our observations in YYMMDD. The x-axis is the subradar point west longitude. -- [astro-ph.EP]](https://i0.wp.com/astrobiology.com/wp-content/uploads/2026/08/Radar-observations.png?resize=1200%2C751&ssl=1)
