How Do Telescopes See the Past? The Simple Reason Every Star Is History
When you look at the Moon, you see it as it was about 1.3 seconds ago. The delay is too short to notice, but the principle is the same for…

Scientists Read 4,000-Year-Old Letters Without Opening Their Clay Envelopes
Researchers are using high-definition X-ray CT and virtual unwrapping to read cuneiform letters that remain sealed inside their ancient clay envelopes.
Betelgeuse Finally Reveals Its Companion After a Century of Searching
Betelgeuse has been watched for thousands of years, but the red star still had one secret that refused to give itself up. Astronomers had long suspected that a fainter companion…
Webb Finds Dust and Water Surviving Near the Milky Way’s Central Black Hole
The centre of the Milky Way is a difficult place for fragile molecules. Sagittarius A*, the supermassive black hole at the heart of our galaxy, is surrounded by intense radiation,…
What Is an Interstellar Object, and How Do Astronomers Know It Came From Another Star?
Most comets and asteroids that pass through the Solar System are permanent residents. The Sun’s gravity keeps them on closed orbits, even when those orbits take thousands of years to…
Could the Milky Way Eventually Look Like the Center of the Universe?
The Milky Way is not the center of the universe. No observation has placed Earth or our galaxy in a privileged position, and the large-scale universe looks broadly the same…
Reported White Sands Orb Recoveries Could Be Tested in a Lab—If the Materials Are Released
A new report about alleged UAP recoveries near White Sands is circulating because it makes a testable promise. If fragments or intact objects were actually recovered, researchers could study the…
Fifth U.S. UAP Release: What the Witness Testimony Adds to the Record
The fifth U.S. UAP release adds witness testimony to the public record. The documents do not identify what produced the sightings, but they show what was reported, what details can…
Euclid Finds 31 Ancient Quasars From the Universe’s First 700 Million Years
Euclid has found 31 quasars from the universe’s first 700 million years, giving astronomers a new way to study how early supermassive black holes grew.
How Can Archaeologists Date a Ditch That Has Almost Disappeared?
Archaeologists do not always find a monument in the form people imagine. A stone circle may survive as a scatter of sockets. A burial mound may be flattened into a…
Archaeologists Used Light to Date a Faint Neolithic Enclosure in Suffolk
The outline of a Neolithic monument can disappear long before the site stops carrying information. At Sizewell on the Suffolk coast, archaeologists found a large rectangular enclosure whose ditches had…
Avi Loeb’s UAP Council: What the New Memo Says About Secret Aircraft and Non-Human Technology
Avi Loeb’s latest UAP essay asks whether some unresolved objects might be classified aircraft—or technology no government has publicly acknowledged. The distinction matters because the same sighting can look like…
Avi Loeb’s Interstellar Hitchhiking Idea Starts With a Real Engineering Advantage
Sending a spacecraft between stars is difficult for a reason that is easy to underestimate: the spacecraft has to leave one planetary system and arrive at another with enough speed,…
Radar Reveals a Hidden Prehistoric Structure at Hierakonpolis
A new study at Hierakonpolis used high-resolution ground-penetrating radar to map a large wooden palisade beside a Predynastic ceremonial center.
Why Is Space Dark If the Universe Is Full of Stars?
Look up on a clear night and the sky between the stars is mostly black. That seems obvious until you ask a deceptively simple question: if the universe contains an…
Göbekli Tepe Archaeological Excavations: Were These 10,000-Year-Old Buildings Homes?
Göbekli Tepe excavations have uncovered rectangular buildings that may have been homes. The find adds an everyday setting to a place long known for its monumental pillars and enclosures, giving…
What Is the Kuiper Belt? The Icy Region Beyond Neptune
The Kuiper Belt is a broad, cold region beyond Neptune where millions of icy bodies orbit the Sun. Pluto is the best-known member, but it is only one of many…
What Is Vacuum Birefringence? The Quantum Effect Seen Around Magnetars
Vacuum birefringence sounds like a contradiction. A vacuum is supposed to be empty, while birefringence is a property associated with materials such as crystals. In quantum physics, however, empty space…
Why a UAP’s Distance Matters More Than the Video
Most UAP videos show brightness and apparent motion, but very few establish how far the object was from the camera. That missing measurement is why a dramatic clip can suggest…
DESI Has Finished Its Five-Year Map. The Dark-Energy Answer Still Is Not Here
The Dark Energy Spectroscopic Instrument has completed the observing campaign that was designed to map the large-scale structure of the universe. The survey has recorded spectra for more than 47…
New FBI UAP Files: What the Red Lights and “Plasma-Like Sphere” Reports Say
AARO's June release includes FBI-linked UAP files describing two red lights, a changing luminous sphere and a hovering light. Here is what the records establish—and what they leave unanswered.
Why Do Some Dying Stars Leave Behind Glowing Bubbles?
When a star like the Sun reaches the end of its life, it does not simply switch off. It can spend thousands of years pushing its outer atmosphere into space,…
Webb’s New Lion Nebula Image Shows a Dying Star Shaping a Cosmic Face
The Lion Nebula looks like a face because a dying star has spent thousands of years shaping the material around it. NASA’s James Webb Space Telescope has now photographed the…
How Do Scientists Decide Whether a UAP Is Truly Unidentified?
The word “unidentified” sounds stronger than it is. In a serious investigation, it usually means that the available information does not yet identify an object. It does not mean that…
