The Discovery of Water in Space
How Scientists Detected Water in the Universe
The discovery of water in space is a monumental achievement that has reshaped our understanding of the cosmos. Scientists have long speculated about the presence of water beyond Earth, but it wasn’t until advanced technology became available that they could confirm its existence. Using powerful telescopes like the Atacama Large Millimeter/submillimeter Array (ALMA) and the Hubble Space Telescope, researchers identified water vapor in distant galaxies and even within our solar system. For instance, water was detected on Mars, Europa, and Enceladus, but the largest reservoir was found near a quasar 12 billion light-years away. This discovery was made possible by analyzing the unique spectral signatures of water molecules, which absorb and emit specific wavelengths of light.

The Role of Telescopes and Technology in the Discovery
Modern technology has played a pivotal role in uncovering the secrets of water in space. Telescopes equipped with infrared and submillimeter wave detectors have been essential in identifying water molecules in the most remote corners of the universe. For example, the Herschel Space Observatory provided groundbreaking data on water in star-forming regions, while ALMA allowed scientists to study water vapor in distant quasars. Additionally, space probes like Cassini and Juno have provided close-up observations of water on moons and planets. These technological advancements not only confirm the presence of water but also help scientists understand its distribution and abundance.

This chapter sets the stage for understanding how the discovery of water in space was made, the tools that made it possible, and why it matters for our broader understanding of the universe.
Where Is the Largest Amount of Water Located?
The Cosmic Reservoir: A Quasar 12 Billion Light-Years Away
The largest amount of water ever discovered in space is located near a quasar known as APM 08279+5255, approximately 12 billion light-years from Earth. This quasar harbors a supermassive black hole surrounded by a massive disk of gas and dust. Within this disk, scientists detected a reservoir of water vapor that is 140 trillion times the volume of Earth’s oceans. This discovery was made using the Z-Spec instrument at the Caltech Submillimeter Observatory and confirmed by the Combined Array for Research in Millimeter-wave Astronomy (CARMA). The water vapor not only highlights the quasar’s immense energy but also provides insights into the early universe’s conditions.

Comparing Earth’s Water to the Space Water Reservoir
When comparing Earth’s water to the cosmic reservoir near APM 08279+5255, the scale is almost incomprehensible. Earth’s oceans contain about 1.332 billion cubic kilometers of water, while the quasar’s water vapor is equivalent to 140 trillion times that amount. This staggering difference underscores the vastness of the universe and the abundance of water in extreme environments. Interestingly, despite the immense quantity, this water is not in liquid form but exists as vapor due to the quasar’s intense heat and radiation.

The Significance of Water in Distant Galaxies
The presence of water in distant galaxies like the one hosting APM 08279+5255 is significant for several reasons. First, it demonstrates that water was abundant even in the early universe, just 1.6 billion years after the Big Bang. Second, it suggests that water is a universal molecule, forming under a wide range of conditions. Finally, this discovery provides clues about the processes that govern star and galaxy formation, as water vapor plays a role in cooling gas clouds and enabling gravitational collapse. Understanding these processes helps scientists piece together the puzzle of cosmic evolution. For more insights into the role of water in galaxy formation, visit ESA’s Science & Exploration.

How Water Forms in the Universe
The Chemistry Behind Water Formation in Space
Water, a simple molecule composed of two hydrogen atoms and one oxygen atom (H₂O), forms in space through a series of chemical reactions. These reactions often occur in molecular clouds, where temperatures are extremely low, and atoms and molecules can bond more easily. For instance, oxygen atoms released by dying stars can combine with hydrogen molecules to form water. Additionally, ultraviolet radiation from nearby stars can trigger these reactions on the surfaces of dust grains. Over time, these water molecules accumulate, creating vast reservoirs.

The Role of Stars and Planetary Systems in Creating Water
Stars play a crucial role in the formation and distribution of water throughout the universe. During their life cycles, stars fuse hydrogen into heavier elements like oxygen, which is essential for water formation. When massive stars explode as supernovae, they scatter these elements into space, enriching interstellar clouds. Later, within planetary systems, water can form on dust grains and comets, eventually becoming part of planets and moons. For example, Earth’s water is believed to have been delivered by comets and asteroids during its early formation.

Could Water in Space Support Life?
The presence of water in space raises exciting questions about the potential for extraterrestrial life. Water is a fundamental requirement for life as we know it, serving as a solvent for biochemical reactions. While the water vapor near quasars is too hot and energetic to support life, other regions, such as the icy moons Europa and Enceladus, offer more promising environments. These moons have subsurface oceans that could harbor microbial life. Scientists are also studying exoplanets within the habitable zones of their stars, where liquid water could exist.

Implications for the Search for Extraterrestrial Life
Water as a Key Indicator of Habitable Planets
Water is universally recognized as a critical ingredient for life, making it a primary focus in the search for habitable planets. Scientists use the concept of the “habitable zone,” or the region around a star where temperatures allow liquid water to exist, to identify potential candidates. Planets like Proxima Centauri b and TRAPPIST-1e are prime examples, as they orbit within their stars’ habitable zones. Additionally, the presence of water vapor in a planet’s atmosphere, detected through spectroscopy, can signal the possibility of life-sustaining conditions.
