High-intensity X-ray beams are now challenging the leading theory about who — or what — built the ancient LSU campus mounds.

A giant rocky exoplanet so dense it shouldn't exist is forcing astronomers to rethink how planets form in the first place.

Gravity's standard equations can't explain why galaxies spin the way they do — a new information-physics theory claims the fix lies in rethinking what information itself is.

A 170-million-year-old rocky "mega-Earth" is so dense and large that it shouldn't exist — and astronomers say it breaks the rules of how planets form.

Tabby's Star dims in patterns no known natural process fully explains — fueling a live debate between dust clouds, a companion planet, and alien megastructures.

Scientists now have a new working theory for what triggered New Jersey's 2024 earthquake — and the answer may rewrite assumptions about seismic risk in the Northeast.

A magnitude-4.8 quake rattled New Jersey in April 2024, and experts immediately blamed the Ramapo Fault — but new findings say they were wrong.

A 2-billion-year-old rock formation is challenging what geologists thought they knew about Earth's ancient carbon cycle — and the disruption it points to was global.

A star whipping around a black hole at 15,000 miles per second is now a live test of whether Einstein's relativity holds in the most extreme gravity in the universe.

The same cause killed 43% of a studied astronaut group — and scientists now think spaceflight itself may be rewiring the heart.

White patches spotted on B-2 stealth bombers have aviation analysts split between routine maintenance, radar-absorbent coating repairs, and something more classified.

Earth's shield against extreme space weather may work differently than scientists assumed — and the gap in understanding has real stakes for satellites, GPS, and power grids.

A brand-new type of "black hole star" — the farthest ever found — is forcing astronomers to rethink how the earliest stars in the universe formed.

A NASA Mars photo shows what looks like a moving jellyfish — and the gap between what the camera captured and what people see reveals how hungry minds find life in rocks.

A NASA Curiosity rover photo shows a rock formation so jellyfish-like that it's reigniting debate: are we wired to see life where there is none?

A viral claim said Earth would lose gravity for seven seconds on August 12, 2026 — so NASA had to explain why that's physically impossible.

Viral posts claimed Earth would lose gravity in August 2026 — NASA has now weighed in on whether that fear has any scientific basis.

A viral theory claims a 2026 solar eclipse will trigger gravity loss for seven seconds, killing 40 million people — but what does physics actually say?

A viral claim insists a leaked NASA document proves Earth loses gravity for seven seconds on Aug. 12, 2026 — so why do people keep sharing it?

A viral theory claims Earth could lose gravity for 7 seconds — NASA's scientists weigh in on what would actually happen if it did.
