James Webb telescope spots the earliest galaxy ever recorded
The James Webb Space Telescope spotted the earliest galaxy ever recorded.
Looking through space is also looking through time: We see objects as they were when the light left them, so when we look at the Sun, we see it as it was eight minutes ago.
Newly discovered galaxy MoM z14, which lies a mere 13.53 billion light years away, is also the most distant object ever sighted, so it appears as it was just 280 million years after the Big Bang, when the universe was only 2% of its current age.
As well as being an impressive technical feat, the discovery challenges physicists' models of galaxy formation, implying that they formed more quickly than previously believed.

How could an explosive Big Bang be the birth of our universe?
Curious Kids is a series for children of all ages. If you have a question you'd like an expert to answer, send it to curiouskidsus@ How can a Big Bang have been the start of the universe, since intense explosions destroy everything? – Tristan S., age 8, Newark, Delaware Pretend you're a perfectly flat chess piece in a game of chess on a perfectly flat and humongous chessboard. One day you look around and ask: How did I get here? How did the chessboard get here? How did it all start? You pull out your telescope and begin to explore your universe, the chessboard…. What do you find? Your universe, the chessboard, is getting bigger. And over more time, even bigger! The board is expanding in all directions that you can see. There's nothing that seems to be causing this expansion as far as you can tell – it just seems to be the nature of the chessboard. But wait a minute. If it's getting bigger, and has been getting bigger and bigger, then that means in the past, it must have been smaller and smaller and smaller. At some time, long, long ago, at the very beginning, it must have been so small that it was infinitely small. Let's work forward from what happened then. At the beginning of your universe, the chessboard was infinitely tiny and then expanded, growing bigger and bigger until the day that you decided to make some observations about the nature of your chess universe. All the stuff in the universe – the little particles that make up you and everything else – started very close together and then spread farther apart as time went on. Our universe works exactly the same way. When astronomers like me make observations of distant galaxies, we see that they are all moving apart. It seems our universe started very small and has been expanding ever since. In fact, scientists now know that not only is the universe expanding, but the speed at which it's expanding is increasing. This mysterious effect is caused by something physicists call dark energy, though we know very little else about it. Astronomers also observe something called the Cosmic Microwave Background Radiation. It's a very low level of energy that exists all throughout space. We know from those measurements that our universe is 13.8 billion years old – way, way older than people, and about three times older than the Earth. If astronomers look back all the way to the event that started our universe, we call that the Big Bang. Many people hear the name 'Big Bang' and think about a giant explosion of stuff, like a bomb going off. But the Big Bang wasn't an explosion that destroyed things. It was the beginning of our universe, the start of both space and time. Rather than an explosion, it was a very rapid expansion, the event that started the universe growing bigger and bigger. This expansion is different than an explosion, which can be caused by things like chemical reactions or large impacts. Explosions result in energy going from one place to another, and usually a lot of it. Instead, during the Big Bang, energy moved along with space as it expanded, moving around wildly but becoming more spread out over time since space was growing over time. Back in the chessboard universe, the 'Big Bang' would be like the beginning of everything. It's the start of the board getting bigger. It's important to realize that 'before' the Big Bang, there was no space and there was no time. Coming back to the chessboard analogy, you can count the amount of time on the game clock after the start but there is no game time before the start – the clock wasn't running. And, before the game had started, the chessboard universe hadn't existed and there was no chessboard space either. You have to be careful when you say 'before' in this context because time didn't even exist until the Big Bang. You also have wrap your mind around the idea that the universe isn't expanding 'into' anything, since as far as we know the Big Bang was the start of both space and time. Confusing, I know! Astronomers aren't sure what caused the Big Bang. We just look at observations and see that's how the universe did start. We know it was extremely small and got bigger, and we know that kicked off 13.8 billion years ago. What started our own game of chess? That's one of the deepest questions anyone can ask.

ESA's Solar Orbiter Should Solve Mystery Of Sun's Outermost Atmosphere
ESA's Solar Orbiter mission will face the Sun from within the orbit of Mercury at its closest ... More approach. The European Space Agency's Solar Orbiter mission recently stunned the world with the first-ever full images of our Sun's South pole, proving that this was going to be a mission like no other. Using an orbital gravity assist from the planet Venus, the Solar Orbiter mission spacecraft was able to maneuver into an orbit that has taken it to an angle 17 degrees below the Sun's equator. Over the coming years, the spacecraft will tilt its orbit even further, so the best views are yet to come, says ESA. The 1.2-billion-euro Solar Orbiter mission, with NASA participation, should finally help us understand the origin of the Sun's solar winds as well as our understanding of the Sun's poles. And arguably most importantly, it should solve the puzzle of why our star's outermost atmosphere, or corona, is heated to millions of degrees Kelvin and is thus so much hotter than the Sun's own surface. By contrast, our Sun's visible photosphere, or surface, averages only 5,500 degrees K. With Solar Orbiter, we are clearly seeing energy releases on the nano-flare scale, Daniel Mueller, a solar physicist and ESA project scientist for both ESA's SOHO and Solar Orbiter missions to the Sun, tells me in his office in The Netherlands. But the question is, would these nano-flares continue like that infinitely, or is there a certain lower limit to the production of these nano-flares, Mueller wonders. The puzzle is whether these nano-flares are enough to heat up the Sun's corona to the temperatures with which it is routinely measured. A Unique View Launched in 2020, from its highly elliptical orbit just inside Mercury's perihelion, the closest point in our innermost planet's solar orbit, the ESA spacecraft offers the best views yet of our own yellow dwarf star. We can see on scales down to about 200 kilometers on the Sun, which shows us a lot of dynamics of our star, says Mueller. And thanks to its newly tilted orbit around the Sun, the European Space Agency-led Solar Orbiter spacecraft is the first to image the Sun's poles from outside the ecliptic plane (the imaginary geometric plane in which our Earth orbits the Sun), says ESA. We observed the Sun's North pole at the end of this past April, says Mueller. But we passed the Southern pole first and then the Northern pole six weeks later, he says. At the moment, as seen from Earth, the Solar Orbiter is almost behind the Sun, so the data downlink has slowed to a trickle. But by early October, Mueller expects to have downloaded all the data from Solar Orbiter's Spring polar observations of the Sun. And within a matter of two to three months after the data is on the ground, the first scientific results will have been written up and submitted to journals for publication, says Mueller. These observations are also key to understanding the Sun's magnetic field and why it flips roughly every 11 years, coinciding with a peak in solar activity, says ESA. The spacecraft's instruments show that the Sun's South pole is a bit of a magnetic mess now, with both North and South polarity magnetic fields present, ESA notes. Ready To Flip Right now, there is not a clear dominant magnetic polarity, but a mix of the two, says Mueller. And that is exactly what you would expect to find during the maximum of the Sun's activity cycle, when the magnetic field is about to flip, he says. The real applications are for space weather predictions. Case in point, better space weather forecasting may have saved many of Elon Musk's 523 Starlink satellites that reentered Earth's atmosphere between 2020 and 2024. This period coincides with the rising phase of solar cycle 25, which has shown itself to be more intense than the previous solar cycle, the authors of a 2025 paper appearing in the journal Frontiers in Astronomy and Space Sciences write. Our results indisputably show that satellites reenter faster with higher geomagnetic activity, the authors note. There was a big solar storm that caused the earth's upper Earth atmosphere to expand, so, the satellites experienced more drag, and therefore didn't make it to orbit, says Mueller. One option may have been simply to hold off on launches until this increased period of solar activity enabled a less risky geomagnetic environment in Earth's upper atmosphere. The hope is that the Solar Orbiter mission and other missions like it will lead to better and more reliable space weather predictions that could potentially save hundreds of millions of dollars in the commercial satellite industry. Solar Orbiter should do its share in solving both pure solar physics conundrums as well as in more practical applications like space weather. The good news is that the spacecraft still has plenty of fuel left. Our current funding goes until the end of 2026, but because we had a picture-perfect launch provided by United Launch Alliance and NASA, we saved a lot of fuel, says Mueller. So, the onboard fuel reserves are so large that we can keep going for a long time, he says.
