“Space ice” contains tiny crystals and is not, as previously assumed, a completely disordered material like liquid water, according to a new study by scientists at UCL (University College London) […]

Uncovering Ongoing Surface Modification On Europa
The JWST shows that ice on Europa is developing at different rates in different places, such as Tara Regio, where crystalline ice (lighter colors) is found on the surface as […]

Hybrid Approach Predicts A Lower Binding Energy For Benzene On Water Ice
In this paper we provide a highly accurate value for the binding energy of benzene to proton-ordered crystalline water ice (XIh), as a model for interstellar ices.

A Link Between The Size And Composition Of Comets
All cometary nuclei that formed in the early Solar System incorporated radionuclides and therefore were subject to internal radiogenic heating. Previous work predicts that if comets have a pebble-pile structure […]

Survivability Of Amorphous Ice In Comets Depends On The Latent Heat Of Crystallization Of Impure Water Ice
Comets would have amorphous ice rather than crystalline one at the epoch of their accretion. Cometary ice contains some impurities that govern the latent heat of ice crystallization, Lcry.

The Newly Discovered Form Of Ice Is Very Similar To Liquid Water
A collaboration between scientists at Cambridge and UCL has led to the discovery of a new form of ice that more closely resembles liquid water than any other and may […]

Discovery Of Amorphous Ice May Change Our Understanding Of Water
Researchers at UCL and the University of Cambridge have discovered a new type of ice that more closely resembles liquid water than any other known ices and that may rewrite […]
