Ice can take various forms, but the coldest ice ever discovered is known as Ice XIII. This form of ice is created under extreme conditions, reaching temperatures as low as -160 degrees Celsius.
It has unique properties and a molecular structure that sets it apart from the ice typically found on Earth.
Understanding the different types of ice is crucial, especially when examining the impacts of low temperatures.
Research shows that certain conditions allow for ice to form in ways that differ significantly from the common frozen water we encounter every day.

Understanding Ice and Its Coldest Forms
Ice is not just frozen water; it has various forms and structures that make it interesting.
This section will explore how ice forms, its phases, and the coldest known type of ice.
Ice Structure and Formation
Ice forms when water cools to 0 degrees Celsius (32 degrees Fahrenheit) or below. At this temperature, the movement of water molecules slows down, allowing them to bond together through hydrogen bonds.
These bonds create a crystalline structure unique to ice. The arrangement of molecules leads to ice’s lower density.
Unlike most substances, ice expands when frozen. This property is essential for aquatic life as it allows ice to float on water, insulating the liquid below.
Different forms of ice exist depending on temperature and pressure.
Ice can transition into various phases based on these conditions, demonstrating how versatile water molecules can be.

Phases of Ice
Ice exists in multiple phases, each with its unique structure. The most common phase is hexagonal ice, known as Ice Ih, formed under normal atmospheric conditions.
However, more exotic forms of ice become possible under extreme conditions.
For instance, Ice II, Ice III, and Ice V form under high pressure, each possessing distinct crystal structures. These variations arise due to changes in how water molecules arrange themselves when subjected to different environmental conditions.
Understanding these phases helps scientists predict ice behavior in nature and in experimental settings.
The Coldest Ice: Ice XIII
The coldest form of ice discovered to date is Ice XIII. This ice type forms at temperatures below -70 degrees Celsius (-94 degrees Fahrenheit) and high pressures.
It has a unique structure that differs significantly from common ice forms.
Ice XIII is interesting because it can exist in a superionic state, where protons move freely through the solid structure. This behavior reveals more about the properties of water molecules and their interactions at low temperatures and high pressures.
Such studies are essential for scientific advancements, particularly in fields like cryogenics and planetary science, where understanding extreme conditions is crucial.
Historical and Cosmic Perspectives
Ice has played a critical role in Earth’s history, shaping climates and landscapes. Understanding the significance of cold environments spans from ancient ice ages on Earth to the presence of ice beyond our planet.
Ice Through the Ages
The Pleistocene Ice Ages, which occurred from about 2.6 million to 11,700 years ago, were marked by repeated glaciations. During these periods, vast ice sheets covered significant portions of North America and Europe.
The Neoproterozoic Era, around 1 billion years ago, experienced extreme global cooling events, leading to what is known as “Snowball Earth.”
During this time, ice may have reached the equator, drastically affecting ecosystems.
In addition, volcanic activity and variations in greenhouse gases, such as methane, influenced global temperatures and glaciation patterns. These factors contributed to the complex cycles of warming and cooling, shaping the planet’s current climate.
Extraterrestrial Ice
Ice is not exclusive to Earth.
In space, molecular clouds contain ice grains with elements essential for star formation. These clouds form the basis of future planetary systems.
Other cosmic locations, such as Jupiter’s moon Europa and Saturn’s moon Enceladus, feature icy surfaces that encapsulate vast oceans beneath.
Scientifically, studying these ice bodies can provide insights into potential life beyond Earth.
Moreover, icy comets, traveling through the Solar System, carry organic compounds and water.
Their study helps scientists understand how water and complex molecules may have been delivered to Earth, influencing the planet’s development.
