By reanalyzing Apollo mission rocks, they discovered that the Moon did occasionally generate an incredibly powerful magnetic field, even stronger than Earth’s — but only for fleeting bursts lasting thousands of years or less. Most of the time, the Moon’s magnetic field was weak.

Lab experiments show that key building blocks of proteins can survive tens of millions of years in pure ice, even under relentless cosmic radiation. Ice mixed with Martian-like soil, however, destroys organic material far more quickly. The findings point future missions toward drilling into clean, buried ice rather than studying rocks or dirt.

When solar activity disturbs the ionosphere, it may generate electric fields that penetrate fragile fracture zones in Earth’s crust. If a fault is already critically stressed, this extra electrostatic pressure could help trigger a quake. The idea doesn’t claim direct causation, but it offers a fresh way to think about how space weather and seismic events might interact.

New research suggests the spacecraft caught Uranus during a rare solar wind event that flooded the planet’s radiation belts with extra energy. Similar storms have been seen near Earth, where they dramatically boost radiation levels. The discovery reshapes how scientists think about Uranus—and why it deserves another visit.

A new study proposes that dark stars—hypothetical stars powered by dark matter—could tie all these surprises together. These exotic objects may have grown huge very quickly, lighting up the early cosmos and planting the seeds of supermassive black holes.

Satellites constantly weave past each other, burning fuel and making dozens of evasive maneuvers every year just to stay safe. A major solar storm could disable navigation and communications, turning that careful dance into chaos. According to new calculations, it may take just days—not decades—for a catastrophic chain reaction to begin, potentially choking off humanity’s access to space for generations.

Long-term observations revealed a rare signal flare caused by plasma likely ejected from a nearby companion star. This shows the burst source isn’t alone, but part of a binary system. The finding strengthens the case that magnetars interacting with stellar companions can generate repeating cosmic flashes.

Observations show the black hole is devouring matter far faster than theory says it should—about 13 times the usual “speed limit”—while simultaneously blasting out bright X-rays and launching a powerful radio jet. This surprising combination wasn’t supposed to happen, according to many models, and suggests scientists may be catching the black hole during a brief, unstable growth spurt.

The process produced streams of glowing plasma blobs that rained through the Sun’s atmosphere long after the flare itself. Wed, 21 Jan 2026 03:41:14 EST https://www.sciencedaily.com/releases/2026/01/260121034114.htm https://www.sciencedaily.com/releases/2026/01/260120000318.htm After the Big Bang, the Universe entered a long, dark period before the first stars formed. During this era, hydrogen emitted a faint radio signal that still echoes today. New simulations show this signal could be slightly altered by dark matter, leaving behind a measurable fingerprint. Future radio telescopes on the Moon may be able to detect it and shed light on one of astronomy’s greatest mysteries.

This self-interacting dark matter may trigger a dramatic collapse inside dark matter halos, heating and densifying their cores in surprising ways. Until now, this crucial middle ground of behavior was nearly impossible to model accurately. The new code makes these simulations faster, more precise, and accessible enough to run on a laptop.

New research shows that dark matter particles could have been moving near the speed of light shortly after the Big Bang, only to cool down later and still help form galaxies. By focusing on a chaotic early era known as post-inflationary reheating, researchers reveal that “red-hot” dark matter could survive long enough to become the calm, structure-building force we see today.

But a new study suggests this mysterious ingredient may not be necessary after all. Using an extended version of Einstein’s gravity, researchers found that cosmic acceleration can arise naturally from a more general geometry of spacetime. The result hints at a radical new way to understand why the universe keeps speeding up.

The data revealed giant columns of ultra-hot gas shaped by the star’s magnetic field and glowing in intense X-rays. These features are far too small to image directly, but X-ray polarization allowed scientists to map them with surprising precision. The results open new doors for understanding extreme binary star systems.

Rather than blocking particles, the magnetic field can funnel them along invisible lines that sometimes stretch all the way to the moon. This explains mysterious gases found in Apollo samples and suggests lunar soil may hold a long-term archive of Earth’s history. It could also become a valuable resource for future lunar explorers.

By combining Einstein’s gravity with realistic behavior of light and matter, researchers have built simulations that closely match real astronomical observations. These models reveal how matter forms chaotic, glowing disks and launches powerful outflows as it falls into black holes. It’s a major step toward decoding how these cosmic engines actually work.

A University of Tokyo researcher analyzing new data from NASA’s Fermi Gamma-ray Space Telescope has detected a halo of high-energy gamma rays that closely matches what theories predict should be released when dark matter particles collide and annihilate. The energy levels, intensity patterns, and shape of this glow align strikingly well with long-standing models of weakly interacting massive particles, making it one of the most compelling leads yet in the hunt for the universe’s invisible mass.

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.
