US Edition'Space Ice' Is Less Like Water than Previously Thought
GREATER LONDON, ENGLAND, JUL 7 – New findings reveal space ice is about 20% crystalline, challenging the belief it is fully amorphous and impacting understanding of cosmological processes, researchers say.
- Researchers affiliated with University College London and Cambridge have published findings showing that space ice is composed mainly of amorphous material but also contains minute crystalline formations within it.
- This research challenges the long-held belief that space ice is fully amorphous because cold space conditions supposedly prevent crystal formation during freezing.
- The team combined computer simulations and Earth-based experiments, finding that low-density amorphous ice includes about 20 percent crystalline grains roughly three nanometers wide within 80 percent disordered structure.
- Dr. Michael B. Davies, the study's lead researcher, explained that they now have a clear understanding of the atomic structure of the ice most prevalent throughout the Universe, and highlighted that this type of ice is less effective at transporting molecules essential for the origin of life.
- The findings imply that ice’s role in cosmological phenomena and its potential use as a space material warrant further investigation, particularly regarding its partially crystalline nature.

'Space ice' is less like water than previously thought
"Space ice" contains tiny crystals and is not a completely disordered material like liquid water, as previously assumed, according to a new study by scientists at UCL (University College London) and the University of Cambridge.
Ice in Space Could Do Something We Thought Was Impossible
Water frozen in the darkness of space doesn't appear to behave the way we thought. A new research effort using computer simulations and experiments to explore the most common form water takes in the Universe has found that it is not as structureless as scientists had thought. Rather, repeating patterns – otherwise known as crystals – just a few nanometers across are likely embedded in an otherwise frozen jumble of molecules. Since scientists had…
New Research Uncovers Small Crystals in Interstellar Amorphous Ice
Low-density amorphous ice is one of the most prevalent solid materials in the universe and plays a crucial role in deciphering numerous well-known anomalies of liquid water. Despite its significance and discovery nearly 90 years ago, its structure remains a topic of debate. In a recent study, researchers from the University of London and Cambridge [...] The post New Research Uncovers Small Crystals in Interstellar Amorphous Ice appeared first on…
Space ice is less like water than scientists thought, study finds
Water frozen in the depths of space has long been considered a shapeless, frozen fog. For decades, scientists believed it formed without structure, too cold and still to grow orderly crystals. But a new study by researchers from University College London and the University of Cambridge is challenging that belief. By combining detailed computer simulations with carefully controlled lab experiments, the team found that space ice is not entirely am…

New study shows that space ice is not completely disordered. It contains tiny crystals – with consequences for space travel and the origin of life. The post Hidden Order in Chaos: The Secret of Space Ice was first published on ingenieur.de - Job Market and News Portal for Engineers.
