Space breakthrough as study finds 'key ingredient for life' existed billions of years before we first thought
Water, the key ingredient for life, likely formed just after the Big Bang - suggesting it has been around billions of years longer than previously thought.
A new study has suggested that water came long before galaxies, 'seeding' the formation of planets – and transforming scientists' understanding of how life began.
A team of scientists from the University of Portsmouth have revealed that water already existed in the universe 100 to 200-million years after the Big Bang, the massive explosion that launched space, time and matter 13.8 billion years ago.

In the first study of its kind, researchers modelled the water in the primordial universe – the extremely hot, dense and chaotic state of the cosmos just after the Big Bang. Their findings suggest that habitable planets could have started forming much sooner than previously thought, thanks to early cosmic explosions.
According to the simulations, water molecules began forming shortly after the first supernova explosions, which are known as Population III (Pop III) supernovae. These cosmic events were 'essential' for creating elements like oxygen, which are essential for water, according to the study's leader Dr Daniel Whalen, from the University of Portsmouth's Institute of Cosmology and Gravitation.
Dr Whalen said: 'Before the first stars exploded, there was no water in the Universe because there was no oxygen. Only very simple nuclei survived the Big Bang - hydrogen, helium, lithium and trace amounts of barium and boron. Oxygen, forged in the hearts of these supernovae, combined with hydrogen to form water, paving the way for the creation of the essential elements needed for life."
The research team studied two types of exploding stars: core-collapse supernovae, which generate some heavy elements, and the more powerful Pop III supernovae, which blast huge amounts of metals into space. They found that both types formed 'dense clumps' of gas enriched with water.
Although early supernovae produced only a small amount of water, it was packed into dense gas clouds known as cloud cores, Dr Whelan explains. This is where stars and planets are believed to form.
Dr Whalen said: 'The key finding is that primordial supernovae formed water in the Universe that predated the first galaxies. So water was already a key constituent of the first galaxies. This implies the conditions necessary for the formation of life were in place way earlier than we ever imagined - it's a significant step forward in our understanding of the early Universe."
He added: 'Although the total water masses were modest, they were highly concentrated in the only structures capable of forming stars and planets. And that suggests that planetary discs rich in water could form at cosmic dawn, before even the first galaxies.'
The study, a collaboration between the University of Portsmouth and the United Arab Emirates University. was published in the journal Nature Astronomy.

Check out this interactive map of the early universe, considered largest ever created
Check out this interactive map of the early universe, considered largest ever created An intricate astral tapestry, the map gives stargazers digital views of the ancient cosmos in unprecedented detail and breadth. A team of astronomers have put together the largest, most detailed map of the universe ever created – and you can explore it now. The interactive online map, created using data from NASA's James Webb Space Telescope, details some 800,000 galaxies across a vast cosmic distance – which in astronomy amounts to peering back in time. In fact, some of the galaxies are so far away, they appear as they existed not long after the Big Bang. Depicting a section of the universe known as the COSMOS-Web field, the new map is far more expansive than even the iconic Hubble Ultra Deep Field, a view of 10,000 galaxies NASA released in 2004. Spanning nearly all of cosmic time, the new map has the potential to challenge existing notions of the infant universe, the astronomers who created it claimed in a press release. The best part? The interactive map is available for the public to use. See interactive map of the universe A team of international scientists who are part of the Cosmic Evolution Survey program (COSMOS) created and released the map of the universe Thursday, June 5. Compiled from more than 10,000 images of COSMOS-Web – the largest observing program of James Webb Space Telescope's first year in orbit – the map covers about three times as much space as the moon takes up when viewed from Earth. That makes it the largest contiguous image available from Webb, according to the Rochester Institute of Technology, whose Jeyhan Kartaltepe is a lead researcher on the project. An intricate astral tapestry, the map gives stargazers digital views of the ancient cosmos in unprecedented detail and breadth. Scrolling and zooming in can take users some 13.5 billion years back in time when the universe was in its infancy and stars, galaxies and black holes were still forming. 'If you had a printout of the Hubble Ultra Deep Field on a standard piece of paper, our image would be slightly larger than a 13-foot by 13-foot-wide mural, at the same depth," Caitlin Casey, a physicist at the University of California, Santa Barbara and co-lead for the COSMOS project, said in a statement. "It's really strikingly large.' Explore the interactive map here. NASA's Webb telescope gathers data for online map Using its powerful resolution and infrared capabilities, the James Webb Space Telescope observed a region of space known as the COSMOS-web field, which scientists have been surveying for years. The raw data from the COSMOS field observations was made publicly available once it was collected by Webb, but that didn't mean it was easily accessible. That's why the COSMOS project spent two years creating the map from Webb's raw data to make it more digestible for amateur astronomers, researchers and even the general public. "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," according to a statement from UC Santa Barbara. What is the James Webb Space Telescope? The James Webb Space Telescope, which launched in 2021, far surpasses the abilities of the Hubble Space Telescope, launched 35 years ago in 1990. Orbiting the sun rather than Earth, the Webb is outfitted with a gold-coated mirror and powerful infrared instruments to observe the cosmos like no instrument before. Since reaching the cosmos, Webb has not only facilitated countless scientific breakthroughs in astrophysics, but it also has produced gorgeous images of planets and other celestial objects, including star-forming regions. In March, NASA also deployed into orbit its SPHEREx telescope to collect data on more than 450 million galaxies. Scientists say the SPHEREx observatory will be able to get a wider view of the galaxy – identifying objects of scientific interest that telescopes like Hubble and Webb can then study up close. SPHEREx became operational in May, constantly snapping images of the cosmos. Eric Lagatta is the Space Connect reporter for the USA TODAY Network. Reach him at elagatta@

The Universe's Largest Map Has Arrived, And You Can Stargaze Like Never Before
After many hours of staring unblinking at a small patch of sky, JWST has given us the most detailed map ever obtained of a corner of the Universe. It's called the COSMOS-Web field, and if that sounds familiar, it's probably because an incredible image of it dropped just a month ago. That, however, was just a little taste of what has now come to pass. The full, interactive map and all the data have just dropped, a map that vastly outstrips the famous Hubble Ultra Deep Field's 10,000 galaxies. The new map contains nearly 800,000 galaxies – hopefully heralding in a new era of discovery in the deepest recesses of the Universe. "Our goal was to construct this deep field of space on a physical scale that far exceeded anything that had been done before," says physicist Caitlin Casey of the University of California Santa Barbara, 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, 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." JWST is our best hope for understanding the Cosmic Dawn, the first billion or so years after the Big Bang, which took place around 13.8 billion years ago. This epoch of the Universe is extremely difficult to observe: it's very far away, and very faint. Because the Universe is expanding, the light that travels to us from greater distances is stretched into redder wavelengths. With its powerful resolution and infrared capabilities, JWST was designed for just these observations: finding the faint light from the dawn of time which informs us on the processes that gave rise to the Universe we see around us today. The COSMOS-Web image covers a patch of sky a little bigger than the area of 7.5 full Moons, and peers back as far as 13.5 billion years, right into the time when the opaque primordial fog that suffused the early Universe was beginning to clear. There, the researchers are looking not just for early galaxies, they're looking for an entire cosmic ecosystem – an interactive gravitational dance of objects bound by the cosmic web of dark matter that spans the entire Universe. JWST data collected to date indicates that even with Hubble data, we've barely scratched the surface of what lurks within the Cosmic Dawn. "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 says. "And the big surprise is that with JWST, we see roughly ten times more galaxies than expected at these incredible distances. We're also seeing supermassive black holes that are not even visible with Hubble." This profusion of well-formed galaxies hasn't just surprised astronomers – it's given them a whopping great puzzle to solve. According to our current understanding of galaxy evolution, not enough time had elapsed since the Big Bang for them to have formed. Even one is a bit of a head-scratcher – but the numbers in which JWST is finding them just boggle the mind. With access to datasets free and available to everyone who wants to take a crack, however, we may get a few answers. "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 says. "The best science is really done when everyone thinks about the same data set differently. It's not just for one group of people to figure out the mysteries." Papers on the data have been submitted to the Astrophysical Journal and Astronomy & Astrophysics. Meanwhile, you can head over to the COSMOS-Web interactive website and muck about zooming through the Universe nearly all the way back to the beginning of time.

Giant Jets Bigger Than The Milky Way Seen Shooting From Black Hole
A supermassive black hole in the early Universe has been spotted blasting out powerful jets of plasma that are at least twice as long as the Milky Way is wide. Its host galaxy is a quasar called J1601+3102, and we're seeing it as it was less than 1.2 billion years after the Big Bang. Spanning 215,000 light-years from end to end, this is the largest structure of its kind seen in those early stages of the Universe's formation, and astronomers think it can answer some questions about how they grow. "We were searching for quasars with strong radio jets in the early Universe, which helps us understand how and when the first jets are formed and how they impact the evolution of galaxies," explains astrophysicist Anniek Gloudemans of the National Science Foundation's NOIRLab. Jets are a particularly interesting supermassive black hole behavior. When there is enough material close to a supermassive black hole in the center of a galaxy, it swirls around, forming a disk of material that feeds into the black hole, drawn in by its extreme gravity. That feeding often produces a quasar, blazing with light as the swirling material is heated by friction and gravity to temperatures of millions of degrees. Not all the material falls onto the black hole beyond escape, though. Some of it gets diverted along the magnetic field lines outside the event horizon and accelerated to the black hole's poles, where it is launched into space with tremendous speed. These eruptions of material form jets, and they blast out into space for huge distances. The longest we've found to date are 23 million light-years from end to end, much later in the lifetime of the Universe. However, they only emit light in radio waves, which makes them a little tricky to see. To identify J1601+3102, Gloudemans and her colleagues had to combine observations from multiple telescopes, including the Low Frequency Array (LOFAR) Telescope in Europe, Gemini North in Hawaii, and the optical Hobby-Eberly Telescope in Texas. These observations didn't just reveal the extent of J1601+3102's jets, they allowed the researchers to study the black hole. The amount of light emitted by the quasar activity can be analyzed to reveal the black hole's mass. It's just 450 million times the mass of the Sun, a relatively modest size for a quasar black hole. And it's not scarfing down matter at a particularly high rate, either. These properties suggest that quasars could be more varied than we generally assume. "Interestingly, the quasar powering this massive radio jet does not have an extreme black hole mass compared to other quasars," Gloudemans says. "This seems to indicate that you don't necessarily need an exceptionally massive black hole or accretion rate to generate such powerful jets in the early Universe." The discovery was detailed in The Astrophysical Journal Letters.
