[181][186] Episode Transcript Possible dwarf planet beyond Pluto We begin beyond Neptune, where astronomers have identified a possible new dwarf planet. The object is provisionally called 2026 ED138, and it was found in data from the Vera C. Rubin Observatory in Chile. Early estimates suggest it could be between roughly six hundred and fifteen hundred kilometers wide. That range is broad, but the upper end would make this a substantial member of the outer solar system. It is currently about forty-six times farther from the Sun than Earth is. Astronomers still need a reliable measurement of its size before deciding whether gravity has shaped it into the rounded form required for dwarf-planet status. If confirmed, it would join the five dwarf planets currently recognized by the International Astronomical Union. The discovery is also an early demonstration of Rubin’s ability to expose slow-moving, faint objects that previous surveys missed. Sun’s magnetic field mapped Turning toward the center of our solar system, researchers have reconstructed the Sun’s outer magnetic field in three dimensions on a global scale for the first time. The work reveals both the strength and direction of the magnetic field across observed parts of the corona, the Sun’s extremely hot outer atmosphere. That matters because magnetic energy drives solar flares and eruptions that can send charged particles toward Earth. Those events can...

Webb data suggest mineral clouds could cool this lava world by reflecting much of its incoming starlight. [64] Planets survive a star’s death - Astronomers have identified two debris rings around the white dwarf J1328−1450. The rings may be maintained by surviving planetary bodies, offering a preview of how planetary systems can evolve after their stars die. [100] Webb finds distant ring galaxy - The James Webb Space Telescope has identified GS18660, the most distant known ring galaxy. Its newborn stars and possible companion indicate that a violent collision shaped the galaxy early in cosmic history. [76] Could black holes split apart - New theoretical research finds that a black hole spinning near the maximum rate allowed by physics might be able to divide into two. The scenario remains speculative and would require extraordinarily rare conditions. [150] Episode Transcript Possible new world beyond Pluto Our first story comes from the distant outskirts of the Solar System. Astronomers working with the Vera C. Rubin Observatory have identified a large, icy object beyond Pluto. For now, it carries the provisional designation 2026 ED138, and scientists are calling it a dwarf planet candidate rather than a confirmed dwarf planet. Early estimates leave plenty of uncertainty about its exact size, but its brightness suggests it could rank among the largest objects found in this remote region. The discovery is notable not only for the object itself, but also for what it says about Rubin Observatory. Its main sky survey is designed to repeatedly scan enormous areas of the heavens, making it particularly good at catching faint objects that slowly change position. ED138 may therefore be an early sign that the outer Solar System still has major discoveries waiting for us. [54][55] Hera sees its asteroid targets Staying with nearby small worlds, the European Space Agency’s Hera spacecraft has now distinguished the two asteroids Didymos and Dimorphos as separate bodies for the first time. Until this latest image, the pair appeared to Hera as one unresolved point of light. Dimorphos is especially important because it was struck by NASA’s DART spacecraft in 2022, deliberately changing its orbit around Didymos. That experiment showed that a spacecraft impact could alter an asteroid’s motion. Hera’s job is to examine the aftermath...

Their resemblance to material beyond Neptune hints that planetary building blocks may form in similar ways around different stars. [61][62] Cosmic explosion flared for weeks - Astronomers studied a gamma-ray burst whose central engine continued producing X-ray flares for roughly 27 days, far longer than the previous record. The unexplained activity challenges established ideas about the engines behind ultra-long cosmic explosions. [17] Star collisions seeded early black holes - Simulations suggest that frequent stellar collisions inside crowded early star clusters could have built enormous stars that later collapsed into black-hole seeds. The model may also help explain the mysterious little red dots observed by the James Webb Space Telescope. [106] Lumina recreates the young universe - The Lumina supercomputer simulation follows the first two billion years of cosmic evolution, including the growth of galaxies and the transformation of intergalactic gas. Astronomers can compare its predictions with Webb and Roman telescope observations to test models of the early universe. [121][128] Falcon 9 launches from California - A Falcon 9 launched 27 Starlink satellites from California and returned its first-stage booster to a platform at sea. The flight reflects the increasingly routine use of reusable rockets in modern orbital operations. [46] Episode Transcript Alien comet carries dusty ice We begin with a visitor from another star system. New analysis of James Webb Space Telescope observations has revealed something unusual about the ice surrounding interstellar comet 3I/ATLAS. Instead of resembling the comparatively clean ice grains found around many comets born in our solar system, its water ice appears to be intimately mixed with dark, rocky dust. The grains are extremely small, but their broader message could be important. Their properties resemble material found on some icy bodies beyond Neptune. That similarity suggests the raw ingredients of planets may develop along a shared spectrum, even in systems separated by enormous distances. Because 3I/ATLAS formed around another star and was later cast into interstellar space, it offers astronomers a rare physical sample of an alien planetary system. Every detail helps answer a basic question: Is our solar system chemically unusual, or did it emerge from processes common across the galaxy? In this case, the evidence leans toward at least some common ground. Cosmic explosion flared for weeks From an interstellar traveler, we move to an explosion at the extreme end of cosmic violence. Astronomers have examined a gamma-ray burst known as GRB 220706A, first detected in 2022. What makes it exceptional is not simply the initial burst, but what happened afterward. Its central engine continued producing X-ray flares for around 27 days. The previous record for such delayed activity was about six days, so this event remained active far longer than expected. Gamma-ray bursts are generally linked to catastrophic events such as the collapse of massive stars or the merger of compact objects. They normally fade aft...

[211] NASA speeds science mission selection - NASA’s Competition Model 2.0 will emphasize scientific merit earlier and reduce years of proposal work, potentially allowing researchers to launch more space science missions at lower cost. [284] Launch capacity faces new pressures - Blue Origin has rebuilt a key New Glenn launch-pad tower, while ESA is considering how to prevent a possible Ariane 6 shortage later this decade. The developments highlight growing pressure on global rocket infrastructure. [253][268] Hunter’s Moon meets Saturn - The October Hunter’s Moon reached full illumination early on October 26, with Saturn appearing nearby and the Pleiades providing the next notable skywatching encounter. [77] Episode Transcript Moon rocks arrive on Earth We begin with pieces of the Moon that made their own journey to Earth. Lunar meteorites are rocks blasted away from the Moon by powerful impacts. After traveling through space, a small number eventually fall onto our planet. They are rare, but they can provide something that even the Apollo samples cannot: material that may come from widely scattered and still-unexplored parts of the lunar surface. Scientists can study the chemistry and age of these meteorites to test ideas about the Moon’s early history, including the theory that its young surface was once covered by a vast ocean of molten rock. Some samples could also come from the lunar far side, where comparatively little material has been collected directly. The limitation is that these meteorites arrive without an address. Researchers usually cannot identify the exact crater or region where a rock originated. Even so, taken together with samples returned by American, Soviet and Chinese missions, they can fill important gaps in the Moon’s geological record. In other words, some of our best clues about unexplored lunar territory may already be sitting in laboratories on Earth. [211] NASA speeds science mission selection NASA, meanwhile, is changing how it chooses future science missions. The agency’s new Competition Model 2.0 is intended to reduce the time and money research teams spend preparing proposals. During the opening stage, NASA will place greater emphasis on the strength of the science and require less detailed engineering and financial work. For major competitive programs, including planetary and astronomy missions, NASA expects the selection process to shrink from roughly three years to about a year and a half. Several categories of smaller missions will move to a single-stage competition, rather than asking rival teams to complete another expensive round of studies. That may sound like administrative housekeeping, but it can shape what reaches space. Long and costly competitions consume research budgets before hardware is ever built. A faster process could allow universities and smaller organizations to compete more effectively, while letting NASA respond more quickly to new discoveries. The challenge will be maintaining careful technical and financial review. Selecting a mission quickly is useful only if that mission can ...

The possible first exomoon challenges familiar definitions of moons, planets and stars. [188] Bennu reveals its mixed origins - Chemical analysis of NASA’s Bennu samples suggests the asteroid formed from inner and outer Solar System material mixed near the water-ice line. Jupiter may have controlled which ingredients reached this ancient construction zone. [62] Magnetic web covers quiet Sun - The balloon-borne Sunrise-III observatory found a network of thin magnetic threads above a quiet region of the Sun.

Philippine authorities also warned of risks from discarded rocket components falling into maritime areas. [47][106] Hunter’s Moon meets Saturn - The Hunter’s Moon rises around sunset on October 25, with golden Saturn appearing nearby. The full moon reaches peak illumination shortly after midnight in the eastern United States. [77] Episode Transcript Possible first moon beyond Solar System Astronomers are reporting strong evidence for what could become the first convincing detection of a natural satellite beyond our Solar System. The object lies in the CD-35 2722 system, where a brown dwarf circles a young star. The newly identified companion appears to orbit that brown dwarf. Its gravitational pull produces a small but measurable wobble in the larger object, which researchers tracked using the European Southern Observatory’s Very Large Telescope. The possible satellite is at least as massive as Jupiter, while its brown-dwarf host is more than thirty times Jupiter’s mass. That arrangement creates a classification problem. The companion is large enough to resemble a planet, but it does not directly orbit a star. Calling it a moon also feels strange because it is a giant gaseous body orbiting something that sits between planets and stars. For now, researchers prefer the broader term exosatellite. Additional observations are still needed, but the evidence offers a rare look at how varied planetary systems can be—and why categories based on our own Solar System may not work everywhere. [188] Bennu reveals its mixed origins Closer to home, tiny grains returned from asteroid Bennu are offering a revised account of the Solar System’s earliest years. Researchers at ETH Zurich compared isotopes in the sample and found that Bennu shares a distinctive chemical fingerprint with asteroid Ryugu and a rare class of primitive meteorites. Rather than forming solely in the cold outer Solar System, Bennu’s original material may have gathered near the young Sun’s water-ice line, where dust arriving from both inner and outer regions could mix. Jupiter appears to have played an important role. As the giant planet grew, its gravity may have blocked larger particles while allowing fine dust to circulate around it. That would have helped create the unusually thorough blend preserved in Bennu. The asteroid is therefore less like a sample from one neighborhood and more like an archive of ...
