- Where did Mercury get its water ice? Maybe from a slow asteroid impact in a single Mercurian day
New simulations suggest Mercury's water ice may have been delivered by a massive asteroid impact, similar to the one forming the Hokusai crater, which transported water across the planet in a single Mercurian day (176 Earth days) and trapped it in polar craters.
- These 'interstellar glaciers' could give water to young star systems. Could they support alien life, too?
The article discusses 'interstellar glaciers' in Cygnus X, a star-forming region in the Milky Way, which may supply water to young star systems. These glaciers, containing water ice and polycyclic aromatic hydrocarbons, could also potentially support alien life.
