Webb spots first hints of atmosphere on a potentially habitable world ↗

Astronomers using the James Webb Space Telescope have uncovered compelling evidence for an atmosphere on TRAPPIST-1e, an Earth-sized exoplanet located 40 light-years away in the potentially habitable zone of its star. While researchers have already ruled out a hydrogen-rich primordial atmosphere, the data suggests hints of a secondary atmosphere that could support liquid water on the surface. The planet’s characteristics make it particularly intriguing for astrobiologists seeking worlds that might harbor life. This discovery represents a significant milestone in the characterization of Earth-like exoplanets, as TRAPPIST-1e’s size, rocky composition, and location in the habitable zone make it one of the most promising candidates for detailed atmospheric studies. The findings demonstrate JWST’s capability to detect subtle atmospheric signatures that were impossible to observe with previous telescopes, opening new avenues for investigating the potential habitability of distant worlds.

New telescope cuts through space noise in hunt for distant Earth-like worlds ↗

European researchers are developing the PoET telescope system specifically designed to filter out the “noise” generated by sun-like stars, which has been a major obstacle in detecting Earth-sized planets in habitable zones. The primary challenge in finding true Earth analogs has been the stellar activity—dark spots and granulation patterns—that obscures the faint signals of transiting planets. PoET addresses this by obtaining detailed spectra of stellar surfaces to understand how their characteristics change over time, allowing astronomers to separate stellar interference from genuine planetary signals. The telescope is expected to begin observations by the end of 2025 and will work in conjunction with ESA’s PLATO mission to advance the search for potentially habitable worlds. This technology represents a crucial step forward in exoplanet detection methodology, as identifying Earth-like planets around sun-like stars requires unprecedented precision in distinguishing between stellar activity and planetary transits.

Interstellar comet 3I/ATLAS will be eyed by Mars and Jupiter probes as it zooms past the sun this month ↗

The European Space Agency is leveraging spacecraft originally designed for Mars and Jupiter missions to track interstellar comet 3I/ATLAS during its October 2025 passage through the inner solar system. Discovered in July by an ATLAS telescope in Chile, 3I/ATLAS became only the third confirmed interstellar object detected passing through our solar system, identified by its unusual trajectory and velocity of approximately 130,000 mph. The multi-spacecraft observation campaign represents an unprecedented opportunity to study an object from another stellar system, with Mars and Jupiter orbiters providing unique vantage points impossible to achieve from Earth. Ground-based telescopes are expected to lose sight of 3I/ATLAS in September as its path takes it behind the Sun, making the space-based observations particularly valuable during this critical phase. The coordinated effort demonstrates how existing space missions can be repurposed for opportunistic science, maximizing the scientific return from this rare cosmic visitor before it exits the solar system forever.

Dark matter and dark energy may only be a cosmic illusion ↗

A provocative new study from the University of Ottawa suggests that dark matter and dark energy—thought to comprise 95% of the universe—may not exist at all, but rather represent the observable effects of fundamental forces weakening as the universe expands and ages. Led by adjunct professor Rajendra Gupta, the research proposes that by allowing the coupling constants of nature to evolve over cosmic time and space, the same mathematical framework can explain both galaxy rotation curves (traditionally attributed to dark matter) and cosmic acceleration (attributed to dark energy). The theory, published in the journal Galaxies, represents a radical departure from the standard cosmological model by suggesting that what appears as mysterious dark components are actually natural consequences of how gravity and other forces change in an aging universe. If validated, this “CCC+TL cosmology” could eliminate the need for exotic dark matter particles and dark energy, fundamentally rewriting our understanding of cosmic structure and evolution while explaining observations with a single unified framework rather than requiring separate explanations for different scales.

Astronomers discover the most powerful and distant cosmic ring ever seen ↗

Astronomers using the Low-Frequency Array telescope and citizen scientists from the RAD@home platform have discovered the most distant and powerful “odd radio circle” (ORC) ever detected, designated RAD J131346.9+500320, located at redshift 0.94 when the universe was approximately half its current age. This remarkable object features two intersecting rings of radio emission—only the second known example of this configuration—challenging existing theories about how these mysterious structures form. The discovery was published in Monthly Notices of the Royal Astronomical Society and proposes that the rings may be linked to superwind outflows from spiral radio galaxies rather than previously theorized mechanisms. ORCs represent one of astronomy’s newest mysteries, with these vast ring structures measuring hundreds of thousands of light-years across yet remaining invisible in optical wavelengths. The research demonstrates the power of combining professional astronomers with citizen scientists and cutting-edge radio telescope technology, while future observations from the Vera Rubin Observatory will help determine the environments and formation mechanisms of these enigmatic cosmic structures.

Interstellar comet 3I/ATLAS may come from the mysterious frontier of the early Milky Way ↗

New trajectory modeling of interstellar comet 3I/ATLAS suggests it may have originated from the border region between the Milky Way’s thin and thick disks, potentially making it a relic from the early galaxy dating billions of years older than our solar system. Researchers at Universidade da Coruña traced the comet’s path backward through 4 million years and found that none of the stars in the solar neighborhood significantly influenced its trajectory, indicating it has been traveling through interstellar space for an extraordinarily long time. The thin disk contains younger, metal-rich stars and most of the galaxy’s star-forming regions, while the broader thick disk harbors much older, metal-poor stars that ceased forming long ago. If 3I/ATLAS indeed comes from this boundary region, it could preserve pristine material from when the galaxy was much younger, offering astronomers a unique window into the conditions and composition of the early Milky Way. This finding adds another layer of scientific importance to the already unprecedented opportunity to study only the third confirmed interstellar object ever detected passing through our solar system.

Hubble telescope finds galaxy with puzzling shape ↗

The Hubble Space Telescope has captured detailed images of NGC 2775, a galaxy located 67 million light-years away that defies easy classification, exhibiting characteristics of both spiral and elliptical galaxies simultaneously. The galaxy features a smooth, gas-devoid center resembling an elliptical galaxy while also displaying a dusty ring with patchy star clusters typical of spiral galaxies, leaving astronomers uncertain about its true nature. Some researchers classify NGC 2775 as a lenticular galaxy—an intermediate type with features of both spirals and ellipticals—though the exact formation mechanisms of such hybrid galaxies remain poorly understood. The single viewing angle available from Earth makes definitive classification particularly challenging, as the galaxy’s three-dimensional structure cannot be fully determined from our perspective. Objects like NGC 2775 are scientifically valuable because they may represent transitional stages in galaxy evolution, potentially showing how galaxies transform from one type to another over cosmic timescales through processes like past interactions or the gradual depletion of gas and dust.

Black hole discovery confirms Einstein and Hawking were right ↗

The detection of gravitational waves from black hole merger GW250114 by LIGO in January 2025 has provided the clearest evidence yet confirming fundamental predictions made by Albert Einstein and Stephen Hawking about black hole behavior. The remarkably strong signal—involving two black holes of approximately 33 solar masses each coalescing into a 63-solar-mass black hole—was so clear that scientists could measure the spin of all three black holes with exceptional accuracy and detect multiple tones in the final black hole’s “ringing.” The observations confirmed the Kerr solution prediction that black holes are fully described by just two numbers (mass and spin) and validated Hawking’s area theorem stating that a black hole’s event horizon can only grow, never shrink. Published in Physical Review Letters by the LIGO-Virgo-KAGRA Collaboration, the results represent a major milestone in gravitational wave astronomy enabled by recent improvements to LIGO’s detection capabilities. The unprecedented precision of these measurements offers long-sought confirmation of how black holes work while hinting at deeper connections between gravity, entropy, and quantum theory that could help unify our understanding of physics.

Rogue black hole 300,000 times larger than the sun found zooming through distant dwarf galaxy ↗

Astronomers have discovered an intermediate-mass black hole—one of the rarest types of black holes—wandering through dwarf galaxy MaNGA 12772-12704 located 230 million light-years away, actively feeding and producing powerful radio jets despite being displaced from the galactic center. This remarkable discovery challenges the conventional view that massive black holes remain fixed at the hearts of galaxies and suggests that black hole growth can occur throughout galactic disks and even at galaxy outskirts. Led by Shanghai Astronomical Observatory researchers and published in a statement, the finding utilized data from the Mapping Nearby Galaxies at Apache Point Observatory survey to identify weak AGN activity at the galaxy’s center alongside strong radio emission from the offset position. Intermediate-mass black holes have eluded astronomers for decades as a “missing link” between stellar-mass and supermassive black holes, making this active, wandering example particularly significant. The discovery has important implications for understanding how supermassive black holes grew so rapidly in the early universe and how galaxy mergers and gravitational interactions can eject black holes from their central positions while they continue to accrete matter and influence their surroundings.

A Single, ‘Naked’ Black Hole Rewrites the History of the Universe ↗

The James Webb Space Telescope has discovered an essentially isolated black hole as massive as 50 million suns existing in the early universe without a significant parent galaxy, challenging the textbook understanding that galaxies form before their central black holes. Dubbed QSO1 and detailed in a preprint by Roberto Maiolino’s team at the University of Cambridge, this “naked” black hole appears to contradict the established sequence of galaxy formation where stellar collapse and black hole mergers were thought to create supermassive black holes only after galaxies had already formed. The discovery has profound implications for cosmology, potentially providing the first evidence for primordial black holes—theoretical objects predicted by Stephen Hawking in 1971 that could have formed directly in the Big Bang’s primordial soup. The finding represents a complete paradigm shift where black holes might precede and help build their host galaxies rather than being consequences of galaxy formation, offering a possible solution to the longstanding mystery of how supermassive black holes grew to enormous sizes so rapidly after the Big Bang. This observation exemplifies how JWST is forcing astronomers to confront a new era of cosmic history that doesn’t fit established models, with implications that extend from black hole physics to the fundamental processes that structured the early universe.

NASA just confirmed its 6,000th alien world. Some are truly bizarre ↗

NASA’s Exoplanet Archive reached the milestone of 6,000 confirmed exoplanets in September 2025, highlighting the rapid acceleration of discoveries since the first exoplanets were detected just over three decades ago. The catalog reveals an astonishing diversity of worlds including “hot Jupiters” orbiting extremely close to their stars, planets covered in lava, gas giants with the density of Styrofoam, and worlds potentially shrouded in clouds of gemstones. This achievement comes primarily from missions like TESS and the James Webb Space Telescope, with upcoming observatories including the Nancy Grace Roman Space Telescope and Habitable Worlds Observatory poised to dramatically expand our census of distant worlds. The diversity of discovered exoplanets has fundamentally changed our understanding of planetary systems, revealing that our solar system represents just one of countless possible configurations. Scientists are increasingly focusing not just on finding more exoplanets but on characterizing their atmospheres, compositions, and potential habitability, with the ultimate goal of detecting biosignatures that might indicate the presence of life beyond Earth.

Astronomers make unexpected discovery of planet in formation around a young star ↗

An international team led by Leiden University, the University of Galway, and the University of Arizona has discovered WISPIT 2b, a Jupiter-like planet approximately 5 million years old still in the process of formation around a young sun analog, captured by the Very Large Telescope in near-infrared observations. This represents only the second confirmed detection of a planet at such an early evolutionary stage around a young sun-like star, providing astronomers with an unprecedented opportunity to study planet-disk interactions and understand how diverse exoplanet systems evolve. The planet, about five times Jupiter’s mass, appears as a glowing infrared dot within a dusty disk featuring multiple concentric rings extending 380 astronomical units from its star—nearly 380 times the Earth-Sun distance. WISPIT 2b is the first unambiguous planet detection in a multi-ringed disk system, making it an ideal laboratory for studying how forming planets carve gaps in their birth disks and accumulate material. The discovery emerged from a five-year observational project investigating whether wide-orbit gas giants are more common around younger or older stars, demonstrating how systematic surveys can yield unexpected insights into planetary system formation processes that ultimately explain the diversity of mature exoplanet architectures observed throughout the galaxy.

James Webb Space Telescope’s first observation of interstellar comet 3I/ATLAS reveals something strange ↗

JWST’s first observations of interstellar comet 3I/ATLAS on August 6, 2025, using its Near-Infrared Spectrograph revealed an unusually high ratio of carbon dioxide to water—one of the highest CO2-to-H2O ratios ever recorded in a comet. This unexpected chemistry, if confirmed through additional analysis, could provide crucial insights into the comet’s mysterious origins beyond our solar system and the conditions in the stellar system where it formed. As only the third confirmed interstellar object ever recorded, 3I/ATLAS offers scientists a rare opportunity to directly sample material from another planetary system before it exits our solar system for good. Initial observations indicate the comet is traveling at speeds exceeding 130,000 mph along an unusually flat and straight trajectory unlike anything native to our solar system, with size estimates suggesting it could be the largest interstellar object ever observed. The unusual chemical composition suggests 3I/ATLAS may have formed in a region or environment significantly different from comets in our solar system, potentially providing clues about the diversity of planetary systems throughout the galaxy and offering a direct comparison between the building blocks of our solar system and those of distant stellar neighbors.

Webb’s Images of Early Galaxies are Providing Fresh Insights into the Early Universe ↗

JWST’s observations of “Little Red Dots” (LRDs)—small, deep red active galactic nuclei that existed just 0.6 to 1.6 billion years after the Big Bang—are triggering revolutionary discoveries about how supermassive black holes formed and how dark matter influenced early galaxy formation. Using the Mid-Infrared Imager to observe the Hubble Ultra Deep Field, astronomers analyzed approximately 2,500 light sources to obtain photometry and redshifts that reveal insights into star formation rates and galaxy evolution shortly after the Big Bang. The observations challenge widely-accepted cosmological models that predicted early galaxies and supermassive black hole seeds wouldn’t have had sufficient time to grow to their observed sizes, creating a fundamental tension with current theories. The MIRI data allows astronomers to peer through dust that obscures these early galaxies in visible light, potentially revealing how the first supermassive black holes formed and why they grew so rapidly surrounded by rings of hot dust. These findings from astronomer Jens Melinder and colleagues at Stockholm University provide critical new data for understanding the formation of heavy elements, the evolution of supermassive black holes, and how the structure of the universe emerged from the cosmic dark ages.

Ever-changing Universe Revealed in First Imagery From NSF–DOE Vera C. Rubin Observatory ↗

The Vera C. Rubin Observatory released its first scientific imagery in June 2025, showcasing unprecedented views of millions of galaxies and thousands of asteroids captured in just over 10 hours of test observations from its location atop Cerro Pachón in Chile. In this brief period, Rubin discovered 2,104 previously unknown asteroids including seven near-Earth asteroids, demonstrating that this single facility will discover millions of new solar system objects within the first two years of its Legacy Survey of Space and Time—far surpassing the combined annual discoveries of all other ground and space-based observatories. The 8.4-meter telescope equipped with the world’s largest digital camera represents more than two decades of development work and will collect more data in its first year than all other optical observatories combined throughout history. Starting later in 2025, Rubin will begin its primary 10-year mission to scan the sky nightly, creating an unprecedented census of transient events including supernovae, variable stars, and potentially hazardous asteroids while studying dark matter, dark energy, and other fundamental cosmic mysteries. The facility’s innovative design enables it to capture wide-field images covering 360-degree strips of sky every 98 minutes, fundamentally changing how astronomers study time-domain astronomy and making the universe’s dynamic nature visible as never before.

MIT joins in constructing the Giant Magellan Telescope ↗

MIT has joined the international consortium constructing the Giant Magellan Telescope in Chile, becoming the 16th member and 10th U.S. participant in the $2.6 billion observatory project enabled by a transformational gift from philanthropists Phillip and Susan Ragon. MIT’s participation comes at a crucial time as the National Science Foundation advanced the GMT into its Final Design Phase in June 2025, one of the final steps before federal construction funding eligibility, with the consortium privately funding this traditionally NSF-supported phase to demonstrate U.S. commitment. The GMT represents a core component of the U.S. Extremely Large Telescope Program identified by the National Academies’ Astro2020 Decadal Survey as “absolutely essential” for maintaining American leadership in ground-based astronomy, working alongside the recently commissioned Vera Rubin Observatory. Already 40% complete with major components being manufactured across 36 U.S. states, the telescope will provide MIT researchers—who conduct over 150 individual science programs annually—with unprecedented capabilities for studying ancient stars, black hole dynamics, and white dwarf systems. The GMT’s seven 8.4-meter mirrors will work together to achieve the resolution of a 25-meter telescope when completed, offering MIT astronomers like Professors Anna Frebel, Erin Kara, and Kevin Burdge access to the world’s most powerful optical telescope for groundbreaking research into cosmic phenomena.

NASA Launches Missions to Study Sun, Universe’s Beginning (SPHEREx) ↗

NASA’s SPHEREx space telescope successfully launched aboard a SpaceX Falcon 9 rocket from Vandenberg Space Force Base on March 11, 2025, beginning its two-year mission to create an unprecedented 3D map of the entire sky in 102 infrared colors. The Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer will map the distribution of more than 450 million galaxies to study cosmic inflation—the brief but powerful event when the universe expanded by a trillion-trillionfold in the first fraction of a second after the Big Bang. SPHEREx will also measure the collective glow from all galaxies throughout cosmic history, including those too faint or distant for other telescopes to detect individually, providing crucial data about how light output from galaxies has evolved over 14 billion years. The observatory’s third major goal involves searching the Milky Way for frozen water, carbon dioxide, and other building blocks of life in interstellar clouds where new stars and planets form, helping determine how likely these essential compounds are to be incorporated into planetary systems. Sharing the launch was NASA’s PUNCH mission, a constellation of four satellites that will study the Sun’s corona and solar wind, with both missions operating in Sun-synchronous orbits that keep the Sun in a constant position relative to the spacecraft—essential for SPHEREx’s thermal management and PUNCH’s solar observations.
