Hidden Crystals in Space Ice Reveal Unexpected Order in Cosmic Waters
Affiliate Disclosure
Hey fellow impactful ninja ?
You may have noticed that Impactful Ninja is all about providing helpful information to make a positive impact on the world and society. And that we love to link back to where we found all the information for each of our posts.
Most of these links are informational-based for you to check out their primary sources with one click.
But some of these links are so-called "affiliate links" to products that we recommend.
Why do we add these product links?
First and foremost, because we believe that they add value to you. For example, when we wrote a post about the environmental impact of long showers, we came across an EPA recommendation to use WaterSense showerheads. So we linked to where you can find them. Or, for many of our posts, we also link to our favorite books on that topic so that you can get a much more holistic overview than one single blog post could provide.
And when there is an affiliate program for these products, we sign up for it. For example, as Amazon Associates, we earn from qualifying purchases.
What do these affiliate links mean for you?
First, and most importantly, we still only recommend products that we believe add value for you.
When you buy something through one of our affiliate links, we may earn a small commission - but at no additional costs to you.
And when you buy something through a link that is not an affiliate link, we won’t receive any commission but we’ll still be happy to have helped you.
What do these affiliate links mean for us?
When we find products that we believe add value to you and the seller has an affiliate program, we sign up for it.
When you buy something through one of our affiliate links, we may earn a small commission (at no extra costs to you).
And at this point in time, all money is reinvested in sharing the most helpful content with you. This includes all operating costs for running this site and the content creation itself.
What does this mean for me personally?
You may have noticed by the way Impactful Ninja is operated that money is not the driving factor behind it. It is a passion project of mine and I love to share helpful information with you to make a positive impact on the world and society. However, it's a project in that I invest a lot of time and also quite some money.
Eventually, my dream is to one day turn this passion project into my full-time job and provide even more helpful information. But that's still a long time to go.

📰 The quick summary: Scientists discovered tiny crystals inside cosmic ice, challenging decades of belief that space ice is completely amorphous and providing new insights about how water behaves throughout the universe.
📈 One key stat: The tiny crystals found in space ice are about three nanometers wide, slightly wider than a single strand of DNA, revealing unexpected order in what was thought to be completely disordered material.
💬 One key quote: “Ice is potentially a high-performance material in space. It could shield spacecraft from radiation or provide fuel in the form of hydrogen and oxygen. So we need to know about its various forms and properties,” said Dr. Davies.
1️⃣ The big picture: Scientists at UCL and the University of Cambridge have made a groundbreaking discovery about the most common form of ice in the universe. Previously thought to be completely amorphous or disordered, space ice actually contains tiny crystalline structures embedded within it. This ice exists on comets, icy moons, and in interstellar dust clouds where stars and planets form. Through both computer simulations and laboratory experiments, researchers found that these tiny crystals make up about 20% of what was previously considered fully disordered ice. The discovery challenges our fundamental understanding of how ice behaves in space environments.
2️⃣ Why is this good news: This finding offers new perspectives on several cosmic processes including planet formation and the movement of matter across galaxies. The discovery provides crucial insights into the physical properties of the most abundant form of ice in the universe, helping scientists better understand water’s behavior in extreme conditions. The research also sheds light on theories about how life may have begun on Earth, particularly addressing the Panspermia hypothesis that suggests life’s building blocks arrived via comets. Understanding the structure of cosmic ice may eventually lead to practical applications, such as developing better radiation shields for spacecraft or identifying new sources of fuel in space exploration.
3️⃣ What’s next: Researchers need to investigate whether the size of crystals varies depending on how the amorphous ice formed. They’ll explore if truly amorphous ice is even possible or if some crystalline structure is inevitable. Scientists must also determine how these findings affect theories about water’s anomalous properties and the transport of organic molecules through space.
