Scientists discover 3 Earth-size exoplanets that may have double sunsets — like Tatooine in Star Wars

DNA from two 7,000-year-old mummies found in the Sahara has uncovered a lost human lineage that remained untouched for 50,000 years.

The ISS has been a symbol of research and cooperation for decades, but NASA has plans to deorbit the station in 2030, likely ending its journey in the water.

Think of ocean plastic and you may picture bottles and bags bobbing on the waves, slowly drifting out to sea.

Small and unassuming, Segue 1 is a nearby dwarf galaxy containing only a handful of stars—too few to provide the gravity needed to keep itself from scattering into space. Like other dwarf galaxies, it was long believed that gravity from a mysterious substance…

XJY-7 launched in 2020 but its purpose has remained unknown.

These species pretend to be something other than what they are — to scare off predators, lure prey or hide.

We cannot see directly beyond the cosmic microwave background, which means we can't directly observe the first 380,000 years of the Universe. But there are indirect ways we might observe this period.

An international team of researchers led by the Leibniz Institute for Astrophysics Potsdam (AIP) has shed light on a decades-long debate about why galaxies spin faster than expected—and whether this behavior is caused by invisible dark matter or by a collapse…

A meteor photobombed the patch of sky containing Comet Lemmon on Oct. 24, wrapping it in a glowing trail.

Scientists detect mercury levels eight times higher in Okefenokee alligators, revealing alarming pollution in southeastern wetlands.

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.
