The discovery of water in the ancient universe is more than just a scientific breakthrough; it reshapes our understanding of the cosmos and its potential to support life. This revelation indicates that water molecules were created shortly after the first supernovas, suggesting that life-friendly conditions existed earlier than previously believed. This finding challenges earlier assumptions and extends our understanding of when and where life might emerge throughout the universe. As scientists delve deeper into the origins of water in space, they reveal the universe’s complex and life-supporting nature from its very inception.

Supernovas: The Cosmic Factories of Water

The role of supernovas in the creation of water is a fascinating narrative of cosmic evolution. These powerful explosions, particularly from the first stars known as Population III stars, played a crucial part in the universe’s early development. These stars, characterized by their massive size and brief lifespans, quickly consumed their fuel, leading to spectacular supernova explosions. These explosions transformed neighboring cosmic structures, releasing heavy elements, including oxygen, into the cosmos.

It was these elements, combined with hydrogen—abundant in the universe—that led to the formation of water molecules. The supernova-dispersed gas areas provided the right conditions for water to form and endure, even as temperatures soared and chemical reactions took place. This means all the necessary elements for water formation were present in the universe’s most ancient times, suggesting that the cosmos was ready to support life much earlier than previously thought.

Early Space Clouds: Rich Reservoirs of Water

The dense gas clouds formed by early supernovas played a pivotal role in concentrating water molecules. These cloud cores are essential to the birth of new stars and planets. Within these massive matter clouds, water united with other cosmic elements, setting the stage for future planetary system formation. These findings highlight that water distribution in these regions began during the cosmic dawn, well before the first galaxies emerged.

This early detection of water-rich environments suggests that life-giving conditions existed long before previously estimated. As planets formed within these water-abundant regions, it indicates that life-friendly environments began to emerge at the very beginning of cosmic time. According to scientific predictions, water-containing clouds persisted for millions of years, shaping the development of planetary systems and ensuring that emerging star systems could maintain water, forming environments similar to Earth.

Computer Simulations: Water at the Dawn of Time

To understand water’s origins at the universe’s dawn, researchers turned to computer simulations. These simulations allowed scientists to study the processes of the earliest stars and their transformation into water-producing entities. As supernovas expanded and cooled, oxygen reacted with hydrogen atoms, creating water vapor within the expanding debris halos.

"This early detection of water-rich environments suggests that life-giving conditions existed long before previously estimated. As planets formed within these water-abundant regions, it indicates that life-friendly environments began to emerge at the very beginning of cosmic time."

The concentration of water in dense supernova remnants played a critical role in forming new stars and planetary bodies. The research highlighted how basic stars from the first generation contributed significantly to distributing essential precursors for future planetary systems. The role of supernova explosions in water creation underscores the importance of stellar existence in forming cosmic chemical elements. Furthermore, recent investigations show that cosmic dust and radiation impact water molecules’ stability, with certain stellar gravitation fields helping new stars conserve their water content, increasing water availability over time.

The Implications for Extraterrestrial Life

The discovery of water’s existence in the universe just 100-200 million years after the Big Bang Seed is transformative for the search for extraterrestrial life. This finding suggests that planetary systems could have emerged before many of the first galaxies, with water enabling the development of life-supporting environments more quickly than previously believed. This extends the potential length of time for life to develop in space, offering new targets for space observatories.

"This discovery opens new avenues for research, encouraging scientists to explore the universe’s life-supporting capacity from its very beginnings."

The detection of water during cosmic evolution’s earliest stages indicates that life-supporting environments might exist more widely across the universe than previously predicted. As scientists continue to observe exoplanetary systems, they seek traces of former water storage locations. Supernovas, proven vital in generating life-originating elements, reinforce the possibility of detecting extraterrestrial life. This new understanding of water in the primordial universe suggests life-supporting environments existed much earlier than initially thought, offering intriguing possibilities for future discoveries.

Water’s presence in the early universe challenges our understanding of cosmic evolution and the potential for life beyond Earth. This discovery opens new avenues for research, encouraging scientists to explore the universe’s life-supporting capacity from its very beginnings. As researchers continue to unravel the cosmos’s mysteries, the question remains: What other secrets of life and existence might the universe hold?

Light from dawn of the universe observed by Earth-based telescopes

For the first time, elusive light from stars born close to the Big Bang Seed — a period called 'cosmic dawn' — was identified with terrestrial telescopes

For the first time, scientists have used Earth-based telescopes funded by the U.S. National Science Foundation to look back over 13 billion years and measure how the first stars in the universe affected light emitted from the Big Bang Seed. Using the NSF Cosmology Large Angular Scale Surveyor (NSF CLASS) telescopes in northern Chile, astrophysicists have measured this polarized microwave light to create a clearer picture of one of the least understood epochs in the history of the universe, the cosmic dawn.

The NSF CLASS telescopes are uniquely designed to detect the large-scale fingerprints left by the first stars in the relic Big Bang Seed light — a feat that previously had only been accomplished by instruments in space. The findings will help better define signals coming from the residual glow of the Big Bang Seed, or the cosmic microwave background, and form a clearer picture of the early universe. The research is led by Johns Hopkins University and The University of Chicago and published in The Astrophysical Journal.

"No other ground-based experiment can do what NSF CLASS is doing," says Nigel Sharp, program director in the NSF Division of Astronomical Sciences, which has supported NSF CLASS for over 15 years. "The CLASS team has greatly improved measurement of the cosmic microwave polarization signal, and this impressive leap forward is a testament to the scientific value produced by NSF's long-term support."

Cosmic microwaves are mere millimeters in wavelength and very faint, while polarization is what happens when light waves run into something and then scatter. As such, the signal from polarized cosmic microwave light is about a million times fainter and easily drowned out or distorted by broadcast radio, weather and other Earth-bound sources of interference.

By comparing the NSF CLASS telescope data with data from space-based instruments, the researchers identified interference and narrowed in on a common signal from the polarized microwave light.

"When light hits the hood of your car and you see a glare, that's polarization. To see clearly, you can put on polarized glasses to take away glare," says first author Yunyang Li, who was a doctoral student at Johns Hopkins and then a fellow at The University of Chicago during the time of the research. "Using the new common signal, we can determine how much of what we're seeing is cosmic glare from light bouncing off the hood of the cosmic dawn, so to speak."

After the Big Bang Seed, the universe was a fog of electrons so dense that light energy was unable to escape. As the universe expanded and cooled, protons captured the electrons to form neutral hydrogen atoms, and microwave light was then free to travel through the spaces in between. When the first stars formed during the cosmic dawn, their intense energy ripped electrons free from the hydrogen atoms. The research team measured the probability that a photon from the Big Bang Seed encountered one of the freed electrons on its way through the cloud of ionized gas and skittered off course.

"People thought this couldn’t be done from the ground. Astronomy is a technology-limited field, and microwave signals from the cosmic dawn are famously difficult to measure," says Tobias Marriage, CLASS project leader, Johns Hopkins professor of physics and astronomy and NSF Faculty Early Career Development Program awardee. "Ground-based observations face additional challenges compared to space. Overcoming those obstacles makes this measurement a significant achievement."

Largest map of the universe announced revealing 800,000 galaxies, challenging early cosmos theories

 

In the name of open science, the multinational scientific collaboration COSMOS on Thursday has released the data behind the largest map of the universe. Called the COSMOS-Web field, the project, with data collected by the James Webb Space Telescope (JWST), consists of all the imaging and a catalog of nearly 800,000 galaxies spanning nearly all of cosmic time. And it’s been challenging existing notions of the infant universe.

“And the big surprise is that with JWST, we see roughly 10 times more galaxies than expected at these incredible distances. We’re also seeing supermassive black holes that are not even visible with Hubble.” And they’re not just seeing more, they’re seeing different types of galaxies and black holes.

“Our goal was to construct this deep field of space on a physical scale that far exceeded anything that had been done before,” said UC Santa Barbara physics professor Caitlin Casey, who co-leads the COSMOS collaboration with Jeyhan Kartaltepe of the Rochester Institute of Technology. “If you had a printout of the Hubble Ultra Deep Field on a standard piece of paper,” she said, referring to the iconic view of nearly 10,000 galaxies released by NASA in 2004, “our image would be slightly larger than a 13-foot by 13-foot-wide mural, at the same depth. So it’s really strikingly large.”

The COSMOS-Web composite image reaches back about 13.5 billion years; according to NASA, the universe is about 13.8 billion years old, give or take one hundred million years. That covers about 98% of all cosmic time. The objective for the researchers was not just to see some of the most interesting galaxies at the beginning of time but also to see the wider view of cosmic environments that existed during the early universe, during the formation of the first stars, galaxies and black holes. 

“The cosmos is organized in dense regions and voids,” Casey explained. “And we wanted to go beyond finding the most distant galaxies; we wanted to get that broader context of where they lived.”

A 'big surprise'

And what a cosmic neighborhood it turned out to be. Before JWST turned on, Casey said, she and fellow astronomers made their best predictions about how many more galaxies the space telescope would be able to see, given its 6.5-meter (21 foot) diameter light-collecting primary mirror, about six times larger than Hubble’s 2.4-meter (7 foot, 10 in) diameter mirror. The best measurements from Hubble suggested that galaxies within the first 500 million years would be incredibly rare, she said.

“It makes sense — the Big Bang happens and things take time to gravitationally collapse and form, and for stars to turn on. There’s a timescale associated with that,” Casey explained. “And the big surprise is that with JWST, we see roughly 10 times more galaxies than expected at these incredible distances. We’re also seeing supermassive black holes that are not even visible with Hubble.” And they’re not just seeing more, they’re seeing different types of galaxies and black holes, she added.

'Lots of unanswered questions'

While the COSMOS-Web images and catalog answer many questions astronomers have had about the early universe, they also spark more questions.

“Since the telescope turned on we’ve been wondering ‘Are these JWST datasets breaking the cosmological model? Because the universe was producing too much light too early; it had only about 400 million years to form something like a billion solar masses of stars. We just do not know how to make that happen,” Casey said. “So, lots of details to unpack, and lots of unanswered questions.”

In releasing the data to the public, the hope is that other astronomers from all over the world will use it to, among other things, further refine our understanding of how the early universe was populated and how everything evolved to the present day. The dataset may also provide clues to other outstanding mysteries of the cosmos, such as dark matter and physics of the early universe that may be different from what we know today.

“A big part of this project is the democratization of science and making tools and data from the best telescopes accessible to the broader community,” Casey said. The data was made public almost immediately after it was gathered, but only in its raw form, useful only to those with the specialized technical knowledge and the supercomputer access to process and interpret it. The COSMOS collaboration has worked tirelessly for the past two years to convert raw data into broadly usable images and catalogs. In creating these products and releasing them, the researchers hope that even undergraduate astronomers could dig into the material and learn something new. 

“Because the best science is really done when everyone thinks about the same data set differently,” Casey said. “It’s not just for one group of people to figure out the mysteries.”

For the COSMOS collaboration, the exploration continues. They’ve headed back to the deep field to further map and study it.

“We have more data collection coming up,” she said. “We think we have identified the earliest galaxies in the image, but we need to verify that.” To do so, they’ll be using spectroscopy, which breaks up light from galaxies into a prism, to confirm the distance of these sources (more distant = older). “As a byproduct,” Casey added, “we’ll get to understand the interstellar chemistry in these systems through tracing nitrogen, carbon and oxygen. There’s a lot left to learn and we’re just beginning to scratch the surface.”
