Atapuerca Excavation Finds 24 New Homo antecessor Fossils From 850,000 Years Ago
At Spain’s Atapuerca archaeological site, a handful of broken bones can change the shape of an entire chapter in human evolution. During the 2026 field season, researchers recovered at least…
A Body Buried Inside a Canal at Lima’s Ancient Pyramid May Have Been a Ritual Offering
The body was placed on its left side inside a disused canal, with the skull facing Huaca Pucllana's pyramid and the Pacific Ocean. Archaeologists believe the burial may have formed part of a deliberate offering when a ceremonial water feature was closed.
The “Kerry Cow” Wasn’t a Cow—and That Changes When Farming Reached Ireland
Animal bones from Ferriter's Cove were once treated as proof that domestic cattle reached Ireland before farming took hold. A new protein analysis identifies the remains as bear and wild boar instead, overturning a 40-year-old archaeological argument.
Perseverance Found the Mineral Behind Rubies in Strange Rocks on Mars
The rover did not find gemstones scattered across Mars. It detected tiny grains of corundum—the mineral that forms rubies and sapphires—inside pale, silica-rich rocks whose chemistry is difficult to explain.
A Bronze Chariot Emerges From a Sealed Tartessian Site in Spain
Archaeologists working at Casas del Turuñuelo have uncovered an unusually decorated bronze chariot, along with imported objects that trace Tartessian connections across the ancient Mediterranean.
Before the First Humans Land on Mars, Robots Will Have to Build Their First Outpost
Before astronauts land on Mars, autonomous robots may need to scout sites, prepare power, move soil and test life-support systems. Here is how a robot-first outpost could work.
Meteor, Meteoroid or Meteorite? The Difference Explained
What is the difference between a meteor, meteoroid and meteorite? They are three stages of one possible journey: a meteoroid travels through space, a meteor is the bright trail made…
The First Moon Base Will Be Built by Cargo Missions Before Astronauts Arrive
The first permanent foothold on the Moon will not begin with a crew stepping out of a lander and planting a flag beside a finished habitat. It will begin with…
An 8,300-Year-Old Genome Is Giving Prehistoric Japan a Sharper History
An 8,300-year-old woman from prehistoric Japan has become one of the clearest genetic windows yet into the Jōmon world. Researchers have reconstructed a high-coverage genome from her remains, along with…
Did a Roman Political Purge Leave Its Dead Inside This British Villa?
For more than a century, visitors to Brading Roman Villa on the Isle of Wight have come to see its mosaics: Medusa, Bacchus, geometric patterns and the evidence of a…
Mars Has Auroras Like Earth—But NASA Found Them on a Much Smaller Scale
Mars can glow in ultraviolet light when energetic particles strike its upper atmosphere. The planet does not have Earth’s global magnetic field, so scientists have had to work out how…
NASA Photographed the New Crater a Falcon 9 Stage Blasted Into the Moon
Six days after a discarded Falcon 9 stage hit the Moon, NASA steered the Lunar Reconnaissance Orbiter toward the predicted impact site. Its images reveal an 18-metre crater, fresh material thrown from below the surface, and a remarkably accurate impact forecast.
Why Does Saturn Have Rings? What the Icy System Is Made Of
Saturn’s rings look like a solid disk from Earth, but they are closer to a vast, flat swarm of orbiting particles. Most of the material is water ice mixed with…
Curiosity Finds a Vast Honeycomb Landscape on Mars
Curiosity has photographed a broad field of polygonal fractures in a Martian valley, giving scientists another look at the water, sediment, and temperature changes that shaped the planet’s past.
A 12,000-Year-Old Chamber at Karahantepe Is About to Be Opened
Heavy slabs still cover a small room inside one of Karahantepe’s most unusual Neolithic buildings. Archaeologists plan to enter it from above during the 2026 excavation season, opening a space that may have remained closed for roughly 12,000 years.
Did People Live at Göbekli Tepe? The Houses Are Changing Its Story
New surveys have detected possible houses beyond Göbekli Tepe’s excavated monuments, while rooms already uncovered contain benches, grinding stones, storage spaces, and vessels. The famous sanctuary is beginning to look like the centre of a lived-in settlement.
What Happens When a Star Runs Out of Fuel?
A star does not switch off the instant its fuel runs low. The change begins in the core, where nuclear reactions have supported the star against gravity for most of…
NASA Is Extending GPS-Style Navigation to the Moon With a Tiny Receiver
Spacecraft near the Moon cannot simply open a map app and ask where they are. For decades, missions have relied on ground stations to measure their position, calculate a trajectory…
How Do Astronomers Find Exoplanets When They Cannot See Most of Them?
Planets are far dimmer than the stars they orbit, so taking a normal photograph of an Earth-sized world next to a Sun-like star is extraordinarily difficult. Astronomers usually find exoplanets…
Webb May Have Found the Family Tree of the Little Red Dots
What happens to Webb’s mysterious little red dots as the universe ages? The Saguaro galaxy’s red nucleus offers a way to explore their hidden surroundings.
Why Does the Moon Have Almost No Atmosphere?
The Moon does have an atmosphere, but calling it air would be misleading. Its outer envelope is an exosphere: a scatter of atoms so thin that particles can travel long…
Hubble Finds a Spiral Galaxy Being Pulled Out of Shape
Spiral galaxies are often drawn as graceful pinwheels, with arms that curl around a bright centre in something close to balance. NGC 4654 is a one-sided spiral galaxy that does…
MoM-BH*-1: Webb’s Possible “Black Hole Star” at Cosmic Dawn
What is MoM-BH*-1? Webb’s spectrum suggests a possible black hole star wrapped in dense gas at cosmic dawn. Here is what the evidence shows—and what remains uncertain.
