What Astronomers Just Discovered Between Galaxies Changes Everything
For decades, scientists have known that a massive chunk of the universe's ordinary matter was missing. Not dark matter, the elusive substance that doesn't interact with light, but regular, everyday matter made of atoms. And now, thanks to a brilliant use of cosmic radio signals, that mystery may finally be solved. In a new study published in Nature Astronomy, astronomers used fast radio bursts (FRBs)—brief, millisecond-long blasts of energy from deep space—to detect where all that missing matter was hiding: in the vast stretches between galaxies, known as the intergalactic medium. These FRBs are powerful. Though short-lived, they emit as much energy in one burst as the sun does in 30 years. When they pass through space, they act like cosmic flashlights, lighting up the otherwise invisible gas that floats between galaxies. The team measured how the light from 69 FRBs slowed as it moved through this matter, allowing them to "weigh" the fog they passed through. "It's like we're seeing the shadow of all the baryons," explained Caltech assistant professor Vikram Ravi, using the scientific term for this ordinary matter. "With FRBs as the backlight, we now know roughly where the rest of the matter in the universe is hiding." The results show about 76 percent of the universe's baryonic matter exists in this intergalactic fog. Meanwhile, 15 percent of the baryonic matter surrounds galaxies in halos and just 9 percent resides inside the galaxies themselves. This breakthrough was made possible by telescopes like Caltech's Deep Synoptic Array and Australia's Square Kilometre Array Pathfinder, which helped localize the FRBs' origins. Caltech's upcoming DSA-2000 radio telescope, set to detect 10,000 FRBs per year, could be the key to even deeper cosmological insights. For astronomers, it's a milestone moment—one that brings us closer to understanding not just where we come from, but how the universe is truly structured.

Invisible no more: Scientists map 76% of ordinary matter lost between galaxies
For years, the universe held onto a secret that left cosmologists half of the universe's ordinary matter, responsible for building everything from protons and stars to planets and people, has remained elusive due to its diffuse nature. Scientists had considered it 'missing'—until now.' Now, in a breakthrough study, astronomers from Caltech and the Center for Astrophysics | Harvard & Smithsonian (CfA) have managed to directly detect this missing matter using fast radio bursts (FRBs)—brief, powerful flashes of radio waves originating from distant galaxies. These cosmic signals, lasting just milliseconds, serve as precise probes, lighting up the otherwise invisible intergalactic medium. As these FRBs travel billions of light-years to reach Earth, they pass through clouds of ionized gas between galaxies. The radio waves slow down ever so slightly depending on how much matter they encounter along the way. By measuring this delay, known as dispersion, scientists can calculate the amount of invisible matter in the FRBs' path. "The FRBs shine through the fog of the intergalactic medium, and by precisely measuring how the light slows down, we can weigh that fog, even when it's too faint to see," says Liam Connor, assistant professor at Harvard and lead author of the study. The study analyzed 69 well-localized FRBs, each with a host galaxy and known distance. One of the FRBs studied, dubbed FRB 20230521B, is located a staggering 9.1 billion light-years away, making it the most distant fast radio burst ever recorded. Although astronomers have detected over a thousand FRBs to date, only around a hundred have been accurately traced back to their host galaxies. This localization is crucial, as knowing both the origin and distance of an FRB is essential for using it to map the matter it passed through, making these select few key to the current study. Of these, 39 were discovered using the Deep Synoptic Array (DSA)-110, a network of 110 radio antennas in California designed specifically to detect and pinpoint FRBs. The remaining FRBs came from global observatories, including Australia's Square Kilometre Array Pathfinder. Instruments at Hawaii's W. M. Keck Observatory and the Palomar Observatory near San Diego helped determine the distance to each FRB's host galaxy. Their findings confirm that roughly 76 percent of ordinary matter resides in the intergalactic medium, thinly spread across space. Another 15 percent lies in gaseous halos surrounding galaxies, while only a small fraction is found inside galaxies themselves, in stars, or cold galactic gas."It's like we're seeing the shadow of all the baryons, with FRBs as the backlight," said Vikram Ravi, assistant professor of astronomy at Caltech. "If you see a person in front of you, you can find out a lot about them. But if you just see their shadow, you still know that they're there and roughly how big they are." This distribution of matter aligns with predictions made by advanced cosmological simulations but has never been confirmed observationally—until now. The findings also open new avenues for probing fundamental physics. For instance, they may help determine the mass of subatomic particles called neutrinos. While the standard model of particle physics assumes neutrinos have no mass, real-world observations suggest otherwise. Knowing their precise mass could unlock physics beyond current theories. According to Ravi, this is just the beginning for FRBs in cosmology. A new project, Caltech's DSA-2000 radio telescope, currently in development for the Nevada desert, is expected to localize up to 10,000 FRBs each year—dramatically expanding their role in probing the universe's structure. The study, published in Nature Astronomy, was funded by the National Science Foundation.

Bitcoin, Altcoins Pump After Federal Reserve Board Withdraws Crypto Notification Rules For Banks
The board rescinded two supervisory letters and a third one jointly issued with the FDIC and Comptroller of the Currency Bitcoin traded above $94,000 at one point in the night, and all other top altcoins were in the green Some crypto users are concerned the move may result in short-term "uncertainty" among banks Bitcoin and other major cryptocurrencies climbed Thursday night after the Federal Reserve Board (FRB) announced that guidance for banks related to crypto and stablecoin activities was being withdrawn. The move comes just weeks after the Federal Deposit Insurance Corporation (FDIC) made a similar announcement, giving more leeway for banks across the country to engage with the crypto industry. FBR opens a path for crypto and banking activities The Federal Reserve Board said Thursday that it was rescinding three supervisory letters that played a major role in stunted adoption of crypto offerings among American banks and financial institutions. "The Board is rescinding its 2022 supervisory letter establishing an expectation that state member banks provide advance notification of planned or current crypto-asset activities. As a result, the Board will no longer expect banks to provide notification and will instead monitor banks' crypto-asset activities through the normal supervisory process," the board said. It also rescinded a 2023 supervisory letter "regarding the supervisory nonobjection process for state member bank engagement in dollar token activities." Finally, the FRB announced it was withdrawing two jointly issued statements with the FDIC and the Office of the Comptroller of the Currency that limited banks' exposure to cryptocurrencies. It also expressed commitment toward collaborating with other regulatory agencies to consider the possibility of providing further guidance that "support innovation, including crypto-asset activities." Crypto bounces amid the Federal Reserve's pivot Following the announcement, crypto prices surged, signaling the market's positive reaction to the news. Bitcoin was up 1.2% in the day, climbing above $94,000 at one point before settling in at around $93,500. Crypto prices late on April 24, 2025 CoinGecko Ethereum also saw a slight pump, increasing 0.4% in the day, and XRP was up 1.4% in the last 24 hours. All other altcoins on CoinGecko's Top 10 largest crypto assets by market cap were in the green, with Cardano (ADA) leading the day's rally (5.2% up). Questions rise over FRB's move While many in the crypto community were ecstatic over the news, some crypto users raised questions on the short-term impact of the decision. One user pointed out that the long-term effects may result in a more structured playbook under new legislation or unified regulation, but the short-term impact may produce "more uncertainty." The user argued that without formal guidance and only rescinded supervisory notices, "banks may be unsure what is or isn't allowed." One user asked AI chatbot Grok on whether banks can now "just buy what they want," to which the popular AI assistant responded that the announcement may have "relaxed" some crypto guidance but banks are still required to follow general regulations. Uncertainty and a lack of clear rules of the road have hampered growth and adoption in crypto, but U.S. Securities and Exchange Commission Chair Paul Atkins has vowed it will be his administration's priority.
