A 70,000–100,000-year-old site in China’s Lower Yangtze region yielded 3,596 stone artifacts. Their size and manufacture point to a change in toolmaking, but not to a known species or a settled explanation.
Could the young Sun have swallowed a super-Earth? A new solar model finds a possible interior fingerprint, but the event has not been observed.
A chemical record preserved in their teeth suggests that most of the men in Phaleron’s shackled mass graves grew up in Attica. The finding shifts the debate from foreign invaders to violence within the community itself.
The small moons inside Neptune’s rings may be the surviving debris of a much larger moon system destroyed when Triton was captured billions of years ago.
Dark photons are one proposed explanation for dark matter. A new calculation suggests that the early universe’s plasma may have stopped them from depositing heat as efficiently as earlier models predicted.
The enormous Cygnus Bubble is usually linked to a busy star-forming region. A new study argues that the microquasar Cygnus X-3 may be the more natural source of its highest-energy gamma rays.
The cosmic microwave background is the oldest light we can observe. Here is where it came from, what its tiny patterns reveal, and why it still matters.
Electrical surveys at a Neolithic cemetery in Brittany have found strong signs of buried stone clusters inside two huge barrows. Only excavation can show whether the mounds conceal rare human-shaped monuments.
A sub-threshold Einstein Probe X-ray flash was found after ZTF spotted supernova SN 2025wkm. Researchers link the signal to shock breakout and a possible magnetar-powered engine.
A partial radius from Bianfu Cave is the first confirmed Denisovan forearm bone. Together with teeth, skull fragments, tools and animal remains, it offers a rare look at how these elusive relatives of Neanderthals lived in southwest China.
A massive star pair still wrapped in its birth material follows a sharply stretched orbit, while the disks around its two stars point in different directions. Together, those clues suggest the pair may have come together after forming separately.
What can an 8,300-year-old Jomon genome reveal about prehistoric Japan? New high-coverage DNA sharpens the story of migration, isolation and cultural change.
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 ancient star cluster is slowly coming apart in a galaxy 115 million light-years away. The thin trail it left behind is giving astronomers a new way to study dark matter beyond the Milky Way.
What does spolia mean? At Sardis, archaeologists found a late Roman wall built with pieces of an older temple, alongside other evidence of stones reused in streets and monuments.
Three Guangzhou crucibles preserve East Asia’s earliest direct evidence of brass production. The residues confirm local making; the route remains uncertain.
Researchers studying fallen Huashan rock art fragments found a lime-and-blood binder around red pigment. The possible link to childbirth remains an interpretation, not chemical proof.
A FAST–DESI survey of 2.5 million galaxies finds star formation fell far faster than the universe’s atomic hydrogen supply. The mismatch points to how gas becomes molecular.
The Hubble constant measures how quickly the universe expands. Here is how astronomers calculate it—and why two powerful methods still disagree.
An underground LUX–ZEPLIN detector found a 2.6-sigma event that could be dark matter—or an unknown background. Here is why researchers remain cautious.
Hubble has found a growing ten-sided atmospheric wave around Saturn’s south pole—the first large regular-sided jet seen there. Saturn has long been known for a strange shape in its clouds.…
Imagine turning a piece of ancient wood toward the light and finding the faint remains of someone’s handwriting. What did that person need to say? And how could we place…
Twenty-seven faint objects beyond Neptune are giving astronomers a rare look at the planet-building material that survived when the outer solar system stopped growing. The outer solar system is not…
The objects are unusually soft in X-rays but bright in extreme ultraviolet light—exactly the combination that makes them difficult to find and potentially important to the history of stars and…
