Check out this interactive map of the early universe, considered largest ever created

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.
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.'

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.
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.

Ex-NASA Chief Sounds Alarm Over Space Agency's Future

Based on facts, either observed and verified firsthand by the reporter, or reported and verified from knowledgeable sources. Newsweek AI is in beta. Translations may contain inaccuracies—please refer to the original content. The former head of NASA has said that the space agency is "being savaged," in response to proposed cuts by the Trump administration. Bill Nelson, NASA administrator from 2021 to 2025, said: "If they continue on the path that they're on, it will be a crippled agency." NASA has been working on plans to bring astronauts back to the moon for the first time since 1972 with the Artemis program, and to build the Lunar Gateway space station on the moon for long-term lunar scientific exploration. These plans are now on hold amid a proposed Republican budget that would cut as much as half of NASA's science funding. President Donald Trump's budget request to NASA, which must be debated by Congress before October 1, called for the agency to "terminate unaffordable missions," cut "woke" education programs and implement a "more sustainable, cost-effective approach to lunar exploration." Overall, the budget proposes reducing the agency's annual budget from $24.9 billion to $18.8 billion. Newsweek has contacted NASA for comment via email outside of working hours. The Mary W.

Jackson headquarters of the National Aeronautics and Space Administration in Washington, D.C., on Tuesday, May 6, 2025. Gene J. Puskar/AP Photo Why It Matters The Trump administration says that the proposed reductions are necessary to rein in excessive spending, eliminate underperforming projects, and reorient NASA toward more cost-efficient private partnerships. The White House has highlighted examples such as the $4 billion-per-launch cost of the Space Launch System, NASA's expendable heavy-lift rocket. Critics say the proposed budget cuts threaten American progress in space and in scientific endeavor more broadly. In parallel, the administration has proposed eliminating climate satellite projects. Previous scientific cuts by the Trump administration include Health Secretary Robert F. Kennedy Jr. firing vaccine advisers from the Department of Health and Human Services (HHS) and a decrease in grants for scientific research. What To Know Cuts to NASA are creating "chaos" and will likely have "significant impacts to our leadership in space," a Democratic House staffer, speaking on condition of anonymity, told The Sunday Times, a U.K. newspaper. NASA's Artemis project was launched during the first Trump administration and has already cost more than $26 billion for the new Space Launch System. Cutting NASA's budget would also heavily impact space science across Europe, as NASA has partnerships with the European Space Agency (ESA), which was collaborating with NASA and Airbus to build part of the new rockets to the moon and a Gateway space station. This collaboration, which has already cost ESA €840 million in Airbus payments and another €650 million in future Airbus contracts, was supposed to result in three European astronauts going on the new lunar mission. The future of this plan is uncertain. Elon Musk's space exploration company SpaceX still works with NASA, including on lunar exploration. However, he left the federal government and has criticized budget cuts amid a rift with Trump. The future of SpaceX's partnership with NASA is now also uncertain. "The easiest way to save money in our Budget, Billions and Billions of Dollars, is to terminate Elon's Governmental Subsidies and Contracts," Trump wrote on Truth Social in June. What People Are Saying Bill Nelson told reporters at a POLITICO summit: "That's like eating our seed corn. We're not going to have anything to plant next year in the quest of trying to understand what is part of the statutes for NASA, which is to search for life, and therefore to understand who we are, what we are, and where we are." Acting NASA Administrator Janet Petro in a statement in May: "This proposal includes investments to simultaneously pursue exploration of the Moon and Mars while still prioritizing critical science and technology research. I appreciate the President's continued support for NASA's mission and look forward to working closely with the administration and Congress to ensure we continue making progress toward achieving the impossible." The White House in a statement in May: "The Budget phases out the grossly expensive and delayed Space Launch System (SLS) rocket and Orion capsule after three flights. SLS alone costs $4 billion per launch and is 140 percent over budget. The Budget funds a program to replace SLS and Orion flights to the Moon with more cost-effective commercial systems that would support more ambitious subsequent lunar missions." Daniel Neuenschwander, ESA director of human and robotic exploration, quoted in The Sunday Times: "We want to work on reducing the risks of the projects where we are dependent on US decisions. We want to increase the projects which are done in autonomy, where we are the masters of the decisions we take." What Happens Next ESA leaders are looking to work on projects that do not rely on American money or American political decision-makers, turning to work with India and Japan, and possibly even China, instead. Senator Ted Cruz, chair of the Senate Commerce Committee which oversees NASA's budget, has supported Artemis in the past, so it is not certain that NASA's budget will be cut by as much as the Trump administration's proposal by the October 1 deadline.

NASA satellite emits 'spark' decades after going dormant: Astronomers think they know why

Source of the radio waves was tracked to a location that matches that of NASA's defunct Relay 2 spacecraft, which launched in 1964 from Cape Canaveral, Florida. A NASA satellite that had been dead for nearly six decades issued a surprising sign of life. In June 2024, a team of astronomers were perplexed when a radio telescope in Australia scanning the sky over the southern hemisphere came across unusual radio waves. The burst of radiation was very bright, exceedingly quick – and much closer to Earth than the scientists would have thought. After studying the source of the strange cosmic phenomena, the researchers were even more mystified when it appeared to be originating from the same location as a NASA spacecraft that went offline about 58 years ago, according to a press release about the discovery released June 25, 2025. Don't be fooled, though: The defunct spacecraft that operated for about three years in the 1960s isn't kicking back on to resume operations anytime soon. So, what's going on? Here's what to know about the strange signal, and how astronomers tracked it to a defunct NASA satellite. What is NASA Relay 2 spacecraft? Astronomers tracked the source of the radio waves to a location that matches that of NASA's defunct Relay 2 spacecraft, a communications satellite that launched into orbit in 1964 from Cape Canaveral, Florida. The spacecraft operated until June 1967 after both of its onboard transponders failed. So, has the long-dead satellite has suddenly sprung back to life after nearly six decades? Astronomers say that's unlikely. Rather, the waves more likely came from a "spark" of built up electricity, which emitted a pulse as it jumped from one part of the spacecraft to another while passing through charged environment above Earth's atmosphere, according to the researchers. Strange signal originated in Milky Way The team of astronomers discovered the strange signal while hunting for bright, powerful flashes of electromagnetic radiation in the distant universe known as fast radio bursts. Most surprising to the researchers, all of whom are from the International Centre for Radio Astronomy Research, was that the signal spotted June 13, 2024, didn't originate from a far-flung galaxy. Instead, it originated in our own cosmic neighborhood in the Milky Way. While incredibly bright, the event only lasted less than 30 nanoseconds. The astronomers detected it using Australia's national science agency's (CSIRO) ASKAP radio telescope. Clancy James, an astrophysicist at Curtin University in Australia's Perth campus, then led a team that studied the extremely bright source of radio waves to determine its source. While the satellite signal is one possible explanation, the researchers have also theorized that an impact with a tiny particle of space debris, known as a "micrometeoroid," could have caused the anomaly. Such impacts can create short-lived clouds of hot, charged gas that produce bursts of radio waves. Electrostatic discharges could post threats in Earth's orbit The discovery marks the first time that a spark of built-up electricity has been observed to be both so bright and so short in duration. Now that the detection has been made, the finding not only demonstrates how astronomers can help identify the origin of these kinds of signals in the future, but could even help humanity better understand how electrostatic discharges can pose a danger to satellites in Earth's orbit. "Detections like this show how the tools developed to study the distant Universe can help scientists understand the increasingly crowded and critically important space environment close to Earth," the researcher said in a statement. The research has been accepted for publication in Astrophysical Journal Letters. A pre-print version of the paper is available on arXiv.

Rare Jupiter-sized planet discovered 3,200 light-years away using Einstein's space-time warping method

Astronomers used a method once theorized by Albert Einstein to find a mysterious and rare planet on the edge of our galaxy. The planet, AT2021uey b, is a Jupiter-sized gas giant located about 3,200 light-years from Earth in the galactic bulge. It takes AT2021uey b 4,170 days to orbit its dwarf star, according to a study published in the journal Astronomy & Astrophysics. Advertisement According to Live Scence, AT2021uey b's shadow was first spotted in 2021 in data taken by the European Space Agency's Gaia telescope. It took the astronomers multiple check-ins to confirm the details of the planet. The astronomers discovered the planet using microlensing, a method used only three times previously, according to the study. Microlensing, which is based on Einstein's theory of relativity, relies on massive objects moving through the galaxy to warp the fabric of the universe, called space-time. Advertisement 3 An artist's illustration of the Gaia space telescope, which first spotted the microlensing event in 2021. ESA/ATG medialab / SWNS Dr. Marius Maskoliunas, astronomer at Vilnius University and co-author of the study, discussed in a statement posted in just how much work goes into using this method. 'This kind of work requires a lot of expertise, patience and, frankly, a bit of luck. You have to wait for a long time for the source star and the lensing object to align and then check an enormous amount of data,' Maskoliunas said in the statement. 'Ninety percent of observed stars pulsate for various other reasons, and only a minority of cases show the microlensing effect.' 3 A visualization of the Milky Way and Andromeda galaxies. NASA/ESA et al. / SWNS Advertisement According to the study, microlensing occurs when a massive celestial body briefly positions itself directly in front of an even more distant star. As the planet settles in front of the star during its journey, the light begins to curve around the planet, magnifying the light of the star. According to the study, this temporary magnified light is what astronomers are searching for. Maskoliunas gave an example of how to imagine how microlensing works. 3 An illustration depicts NASA's Juno spacecraft in orbit above Jupiter. NASA/JPL-Caltech / SWNS Advertisement 'What fascinates me about this method is that it can detect those invisible bodies. Imagine a bird flying past you. You don't see the bird itself and don't know what color it is — only its shadow,' Maskoliunas said in the statement. 'But from it, you can, with some level of probability, determine whether it was a sparrow or a swan and at what distance from us. It's an incredibly intriguing process.' According to Live Science, there have been nearly 6,000 planets discovered since 1992 using two other more common practices known as transmit photometry and radial velocity. These more common practices will detect planets through host stars becoming dimmer due to said planets. They will also detect the wobble of the planets' gravitational pulls that occur.
