A New Database To Track Origins Of Water From Space
[Rice University]. International collaboration makes decades of satellite data more accessible to scientists studying global water cycle.

An ALMA View On Molecular Complexity: Water, Methanol, And Methyl Formate In The HD 100546 And IRS 48 Disks
[astro-ph.EP] Water and methanol are the fundamental constituents of interstellar and cometary ices: understanding their abundances in disks is therefore of high importance to reveal how this ice reservoir evolves […]

First Detection Of Variable Water Clouds Outside Of Our Solar System
[University Of Arizona]. A Jupiter-sized world just 7.5 light-years away is cloudy, chemically complex, and, it turns out, more like home than anyone expected.
![Mechanisms that contribute to dust growth just beyond the snow line. Many-seed icy aggregates grow in the outer disk’s regions due to the high sticking efficiency of water ice and disintegrate as they cross the water snow line (green-to-blue interface) into silicate monomers and water vapor. Both diffuse back across the snow line due to turbulence, facilitating further accumulation of icy water and the growth of icy aggregates just behind the snow line, effects found in our numerical model as well (see Figs. 7 and E.2).-- [astro-ph.EP]](https://i0.wp.com/astrobiology.com/wp-content/uploads/2026/08/Hydrodynamics.png?resize=1200%2C721&ssl=1)

Hydrodynamics Modeling Of The Water Snow Line In Young Protoplanetary Disks With Dust-size-dependent Opacities
[astro-ph.EP] Aims. We investigated the properties of the water snow line during the early stages of disk evolution, paying particular attention to the effects of gravitational instability and dust growth […]

Astrochemistry: Dust And Water Spotted Close To A Giant Black Hole
[ESA]. Using the NASA/ESA/CSA James Webb Space Telescope, an international team of astronomers have discovered that dust and water can form and survive surprisingly close to the supermassive black hole […]
![This global map of Mars (greys) is overlaid with a map of ice “consistency,” C. Values of C near one (dark blue) indicate a high likelihood of ice in three independent mappings. Lower values of C (lighter blues) indicate lower confidence in ice being present, and indicate detection in at least one dataset. The extreme north and south are both rich in ice (dark blues), ice is absent near the equator, and the presence of ice is uncertain (light blues) in the mid-latitude regions best for astronauts.

Laying Odds On The Potential For Martian Water
[PSI] We know Mars has water ice in its polar regions, but astronauts (and their solar powered equipment!) would much rather experience life closer to Mars’ equator. As NASA looks […]

Distant Exoplanets May Be Hiding Water Beyond Webb Telescope’s Reach, Study Finds
[University of Chicago] The planets that appear most common in the universe could have a lot of water—but it could be hiding where telescopes can’t detect it, according to a […]
