Moss spores survived an extended stay on the outside of the ISS and remained capable of germinating once back on Earth. Their resilience to vacuum, extreme temperatures, and UV radiation surprised the researchers who expected them to perish. The spores' natural protective coat likely played a key role in shielding them. The study hints at the potential for simple plants to support agriculture beyond our planet.

About 4.5 billion years ago, a colossal impact between the young Earth and a mysterious planetary body called Theia changed everything—reshaping Earth, forming the Moon, and scattering clues across space rocks. By examining subtle isotopic fingerprints in Earth and Moon samples, scientists have reconstructed Theia’s possible composition and birthplace.

A massive solar storm in May 2024 gave scientists an unprecedented look at how Earth’s protective plasma layer collapses under intense space weather. With the Arase satellite in a perfect observing position, researchers watched the plasmasphere shrink to a fraction of its usual size and take days to rebuild. The event pushed auroras far beyond their normal boundaries and revealed that a rare “negative storm” in the ionosphere dramatically slowed the atmosphere’s ability to recover. These observations offer valuable insight into how extreme solar activity disrupts satellites, GPS signals, and communication systems.

Researchers have pinpointed a super-Earth in the habitable zone of a nearby M-dwarf star only 18 light-years away. Sophisticated instruments detected the planet’s gentle tug on its star, hinting at a rocky world that could hold liquid water. Future mega-telescopes may be able to directly image it—something impossible today.

Scientists flew the XL-Calibur telescope on a high-altitude balloon to measure polarized X-rays from Cygnus X-1. These measurements reveal details about the chaotic, superheated material swirling around black holes. The team also captured data from the Crab pulsar and achieved multiple technical breakthroughs during the 2024 mission. Another flight from Antarctica is expected to expand this cosmic investigation.

New measurements of radio galaxies reveal that the solar system is racing through the universe at over three times the speed predicted by standard cosmology. Using highly sensitive data from multiple radio telescope arrays, researchers uncovered a surprisingly strong dipole pattern—one that challenges longstanding assumptions about how matter is distributed across cosmic scales. The results echo similar anomalies seen in quasar studies, hinting that something fundamental about our universe’s structure or our motion through it may need rewriting.

New observations show that asteroid 1998 KY26 is a mere 11 meters across and spinning twice as fast as previously thought. The discovery adds complexity to Hayabusa2’s 2031 mission but also heightens scientific interest. The asteroid’s composition remains uncertain, making the encounter even more compelling. Insights from this work could improve future asteroid-defense and exploration efforts.

Scientists may finally be closing in on the origins of two colossal, mysterious structures buried nearly 1,800 miles inside Earth—hidden formations that have puzzled researchers for decades. New modeling suggests that slow leakage of elements from Earth’s core into the mantle prevented the planet from developing strong chemical layers after its primordial magma-ocean era.

Cutting-edge simulations show that Enceladus’ plumes are losing 20–40% less mass than earlier estimates suggested. The new models provide sharper insights into subsurface conditions that future landers may one day probe directly.

Scientists built a tiny clock from single-electron jumps to probe the true energy cost of quantum timekeeping. They discovered that reading the clock’s output requires vastly more energy than the clock uses to function. This measurement process also drives the irreversibility that defines time’s forward direction. The insight could push researchers to rethink how quantum devices handle information.

Astronomers have, for the first time, recorded the moment a star’s explosion broke through its surface. The nearby supernova, SN 2024ggi, revealed a surprisingly olive-shaped blast when studied with ESO’s Very Large Telescope. The discovery helps scientists better understand the forces that drive massive stars to explode and underscores how quick international cooperation can lead to groundbreaking results.

The “Seven Sisters” have far more relatives than anyone imagined. Using NASA and ESA space telescopes, astronomers found thousands of hidden stars linked to the Pleiades, forming a colossal stellar complex. The discovery expands the cluster’s size by a factor of 20 and offers a new way to trace the shared origins of stars—including our own Sun.

Researchers combined deep learning with high-resolution physics to create the first Milky Way model that tracks over 100 billion stars individually. Their AI learned how gas behaves after supernovae, removing one of the biggest computational bottlenecks in galactic modeling. The result is a simulation hundreds of times faster than current methods.

LHAASO has uncovered that micro-quasars, black holes feeding on companion stars, are powerful PeV particle accelerators. Their jets produce ultra-high-energy gamma rays and protons that exceed long-held expectations. Precise cosmic-ray measurements reveal a new high-energy component, suggesting multiple sources within the Milky Way. These findings finally tie the “knee” structure to black hole jet systems.

Researchers at KRISS observed water’s rapid freeze–melt cycles under ultrahigh pressure and discovered Ice XXI, the first new ice phase found in decades. Using advanced high-pressure tech and microsecond XFEL imaging, they uncovered complex crystallization pathways never seen before. Ice XXI’s structure resembles the high-pressure ice found inside Jupiter and Saturn’s moons, hinting at planetary science implications.

Dark matter may be invisible, but scientists are getting closer to understanding whether it follows the same rules as everything we can see. By comparing how galaxies move through cosmic gravity wells to the depth of those wells, researchers found that dark matter appears to behave much like ordinary matter, obeying familiar physical laws. Still, the possibility of a hidden fifth force lingers, one that must be very weak to have evaded detection so far.

A massive, well-preserved impact crater has been uncovered in Guangdong, revealing the signature of a powerful meteorite strike during the Holocene. Measuring 900 meters across, it dwarfs other known craters from the same era. Shock-damaged quartz confirms the intense forces involved. Its survival in a high-erosion environment makes it a geological rarity.

Scientists have finally confirmed a powerful coronal mass ejection from another star, using LOFAR radio data paired with XMM-Newton’s X-ray insights. The eruption blasted into space at extraordinary speeds, strong enough to strip atmospheres from close-orbiting worlds. This suggests planets around active red dwarfs may be far less hospitable than hoped.

A newly detected super-Earth just 20 light-years away is giving scientists one of the most promising chances yet to search for life beyond our solar system. The discovery of the exoplanet orbiting in the habitable zone of its star was made possible by advanced spectrographs designed at Penn State and by decades of observations from telescopes around the world.

Researchers engineered “gyromorphs,” a new type of metamaterial that combines liquid-like randomness with large-scale structural patterns to block light from every direction. This innovation solves longstanding limitations in quasicrystal-based designs and could accelerate advances in photonic computing.

Simulations reveal that Jupiter’s rapid growth disrupted the early solar system, creating rings where new planetesimals formed much later than expected. These late-forming bodies match the ages and chemistry of chondrite meteorites found on Earth. The findings also help explain why Earth and the other rocky planets remained near 1 AU rather than plunging inward.

Arctic sea ice is disappearing fast, and scientists have turned to an unexpected cosmic clue—space dust—to uncover how ice has changed over tens of thousands of years. By tracking helium-3–bearing dust trapped (or blocked) by ancient ice, researchers built a remarkably detailed history of Arctic coverage stretching back 30,000 years. Their findings reveal powerful links between sea ice, nutrient availability, and the Arctic food web, offering hints about how future warming may reshape everything from plankton blooms to geopolitics.

Scientists have identified three Earth-sized planets orbiting two stars in the TOI-2267 system. Remarkably, planets transit around both stars — a first in astronomy. The system’s compact, cold nature defies conventional theories of planetary formation. Future studies using JWST and other advanced telescopes could reveal what these worlds are truly made of.

Astronomers using the James Webb Space Telescope have uncovered a trove of complex organic molecules frozen in ice around a young star in a neighboring galaxy — including the first-ever detection of acetic acid beyond the Milky Way. Found in the Large Magellanic Cloud, these molecules formed under harsh, metal-poor conditions similar to those in the early universe, suggesting that the chemical precursors of life may have existed far earlier and in more diverse environments than previously imagined.

New simulations suggest magnetic fields hold the key to forming black holes that defy known mass limits. When powerful magnetic forces act on a collapsing, spinning star, they eject vast amounts of material, creating smaller yet faster-spinning black holes. This process could explain the puzzling GW231123 collision and the existence of “forbidden” black holes.
