LONDON – In a groundbreaking finding,two teams of astronomers,led by researchers at Caltech,have identified the largest known water reservoir in the universe. this colossal reservoir is located a staggering 30 billion trillion miles away from Earth.
yes, that’s right. The largest body of water ever detected in the cosmos has been found in quasars—some of the brightest and most energetic objects in the universe. The amount of water vapor discovered is estimated to be at least 140 trillion times the volume of all the water in Earth’s oceans combined.
Due to the immense distance of the quasar, its light took 12 billion years to reach our planet.This means the observations captured a moment when the universe was just 1.6 billion years old, providing a rare glimpse into the early cosmos.
“The environment around this quasar is unique in that it produces an enormous mass of water,” said Matt Bradford, a scientist at NASA’s Jet Propulsion Laboratory (JPL). “This is another demonstration that water was widespread throughout the universe, even in its earliest times.”
Quasars are powered by supermassive black holes that devour surrounding gas and dust,releasing immense amounts of energy in the process. While the presence of water in the universe is not entirely unexpected, this discovery sheds new light on the conditions of quasars and their surrounding environments.
The water vapor was detected in a region of gas extending hundreds of light-years around the black hole.This area is unusually warm and dense by astronomical standards, indicating that the quasar’s environment is both dynamic and complex.
Astronomers emphasize the importance of millimeter and submillimeter wavelength observations in making such discoveries.These techniques have advanced significantly over the past few decades, enabling researchers to peer deeper into the universe than ever before.
To further explore the early universe, the study’s authors are working on designing the CCAT-p, a 25-meter telescope planned for construction in Chile’s Atacama Desert. This state-of-the-art telescope will allow scientists to observe some of the oldest galaxies in the universe, unlocking even more secrets of the cosmos.
This discovery not only highlights the vastness of the universe but also underscores the importance of water as a key ingredient in the cosmos. As we continue to explore the mysteries of space, these findings remind us of the interconnectedness of all things in the universe.

Exploring the Cosmic Ocean: an Interview with NASA’s Matt Bradford on the Largest Water Reservoir in the Universe
Table of Contents
In a groundbreaking revelation, astronomers have identified the largest known water reservoir in the universe, located in a quasar 12 billion light-years away. This colossal body of water vapor is estimated to be 140 trillion times the volume of Earth’s oceans. Join us as we discuss this unusual finding with Matt Bradford, a scientist at NASA’s Jet Propulsion Laboratory, who explains the importance of this discovery and what it tells us about the early universe.
The Discovery of a Cosmic Water Reservoir
Senior Editor: Dr. Bradford, thank you for joining us today. Can you start by explaining what a quasar is and why it’s such a unique place to find such a massive amount of water?
Matt Bradford: Absolutely.Quasars are some of the most energetic and brightest objects in the universe. they are powered by supermassive black holes at the centers of galaxies, which devour surrounding gas and dust. This process releases an immense amount of energy, making quasars incredibly luminous. The surroundings around these black holes is dynamic and complex, which is why we’re seeing such an enormous mass of water vapor there.
The Scale of the Discovery
Senior Editor: The amount of water vapor detected is staggering—140 trillion times the volume of Earth’s oceans. What does this tell us about the universe’s capacity to hold water, even in its earliest stages?
Matt Bradford: This discovery is a powerful reminder that water was widespread throughout the universe, even when it was just 1.6 billion years old. The sheer volume of water we’ve found in this quasar suggests that water may have been a fundamental component of the early cosmos. It’s a key ingredient for life as we know it, and its presence in such abundance in the early universe is a fascinating clue about the conditions that existed back then.
Observing the Early Universe
Senior Editor: The quasar’s light took 12 billion years to reach us, giving us a glimpse of the universe when it was very young. How does this observation help us understand the early universe?
Matt Bradford: These observations are like time capsules. By studying light from objects that are incredibly far away, we’re essentially looking back in time.This particular quasar gives us a snapshot of the universe when it was in its infancy. The fact that we’re seeing such a massive amount of water in this environment provides valuable insights into how the universe evolved and how water played a role in that process.
The Role of Advanced Technology
Senior Editor: The article mentions that millimeter and submillimeter wavelength observations were crucial for this discovery. Can you explain how these techniques have advanced our ability to explore the universe?
Matt Bradford: Absolutely. Over the past few decades, advancements in these observational techniques have allowed us to peer deeper into the universe than ever before. These wavelengths are particularly effective at detecting water vapor in distant objects. As technology continues to improve, we’re able to make more precise measurements and uncover new details about the cosmos.
Looking Ahead: The CCAT-p Telescope
Senior Editor: You mentioned the CCAT-p telescope, which is being designed to explore even older galaxies. How will this instrument help us unlock more secrets of the universe?
Matt Bradford: The CCAT-p telescope, planned for construction in Chile’s Atacama Desert, will be a game-changer.With its 25-meter diameter, it will allow us to observe some of the oldest and most distant galaxies in the universe. By studying these ancient objects, we can gain a better understanding of how the universe evolved and what conditions were like in its earliest stages. It’s an exciting step forward in our quest to unravel the mysteries of the cosmos.
The Interconnectedness of the Universe
Senior Editor: what does this discovery meen for our understanding of the universe as a whole? How does it highlight the interconnectedness of all things in space?
Matt Bradford: This discovery underscores the idea that water, and by extension, the potential for life, is a worldwide constant. From the smallest molecules to the largest structures in the universe, everything is interconnected. By studying these distant quasars and their environments,we’re not just learning about the past—we’re also gaining insights into the fundamental processes that shape our universe today and may shape its future.
Senior Editor: Dr. Bradford, thank you for sharing your expertise and insights. This discovery is truly awe-inspiring and reminds us of the vastness and complexity of the universe we inhabit.
Matt Bradford: Thank you for having me. It’s an exciting time to be exploring the cosmos, and I’m looking forward to seeing what we’ll discover next.
