Comet 12P/Pons-Brooks, which visits the Earth roughly every 71 years, was spotted releasing intriguing radio signals last year.

Despite their wide variety of sizes, niches and shapes, sharks scale geometrically, pointing to possible fundamental constraints on evolution.

A dream team of European neuroscientists is advancing toward a unified theory of consciousness, potentially unlocking the mysteries of the mind.

"The national security establishment has already been doing this for five decades but thought that no one could replicate it, so they made it highly classified."

Two Sydney PhD students have pulled off a remarkable space science feat from Earth—using AI-driven software to correct image blurring in NASA’s James Webb Space Telescope. Their innovation, called AMIGO, fixed distortions in the telescope’s infrared camera, r…

I did not sign up for this.

Is it possible that over the past 4.5 billion years of the Earth’s history, alien civilizations visited the solar System and installed…

A massive crater hidden beneath the Atlantic seafloor has been confirmed as the result of an asteroid strike from 66 million years ago. The new 3D seismic data reveals astonishing details about the violent minutes following impact—towering tsunamis, liquefied…

In the Egyptian Western Desert, where red sandstones and green shales rise above the arid plains of Kharga Oasis, paleontologists have uncovered a fossil that fundamentally reshapes our understanding of crocodile evolution.

The planet, the Solar System, and the galaxy aren't expanding. But the whole Universe is. So where does the dividing line begin?

The Southern Ocean has been dutifully gobbling up a century's worth of carbon dioxide and heat released by human activities, but when we finally let go of our fossil fuel habit, it might come back to haunt us.

Experts have managed to reverse quantum state of a single photon in time with 95% accuracy, bringing reversible quantum computing closer.

Beneath the ocean’s surface, the mysterious remains of a colossal creature have become the foundation for a vibrant ecosystem teeming with life.

JWST found a carbon-atmosphere planet orbiting a pulsar, challenging current models of how planets form. Scientific progress often comes from data that don’t fit our current understanding. This idea, first proposed by Thomas Kuhn in The Structure of Scientifi…

Dark-energy evidence suggests the universe will end in a “big crunch” roughly 20 billion years from now. The universe is nearing the halfway point of what may be a 33-billion-year lifespan, according to new calculations by a Cornell physicist using updated da…

The glow-in-the-dark bats you're hanging to decorate for Halloween might be more biologically accurate than you thought.

This study hints that some coral species may be more resilient than previously thought.

Neanderthals and early humans reshaped Europe’s ecosystems long before farming, altering vegetation through fire and hunting.

MIT researchers have devised a new molecular technique that lets electrons probe inside atomic nuclei, replacing massive particle accelerators with a tabletop setup. By studying radium monofluoride, they detected energy shifts showing electrons interacting wi…

Life’s origin story just became even more mysterious. Using mathematics and information theory, Robert G. Endres of Imperial College London found that the spontaneous emergence of life from nonliving matter may be far more difficult than scientists once thoug…

Even the most elite endurance athletes can’t outrun biology. A new study finds that humans hit a metabolic ceiling at about 2.5 times their resting energy burn. When ultra-runners take on races that last for hundreds of miles and continue for several days, th…

"There is no better place to look for [life] than Enceladus,"

Dark matter has two central properties: it has mass like regular matter, and unlike regular matter, it reacts weakly or not at all with light. Neutrinos satisfy these two criteria, but neutrinos move through space at nearly the speed of light, making them a f…

Astrobotic Technology says it now plans to launch its large lunar lander carrying a commercial rover no earlier than mid-2026.

Comet C/2025 A6 (Lemmon) will pass through the neck of the great celestial serpent represented by the constellation Serpens Caput on the nights of Oct. 26-27.
