Two locations are legendary among UFO seekers. One is Roswell, New Mexico, where sightings of a so-called flying saucer electrified the town in 1947. The other is Area 51 near Groom Lake, Nevada, where the U.S. government has long maintained a secret base that some say hides UFO-related technology and experiments.
Archaeologists have uncovered what may be the graves of 50 enslaved workers who labored at an elite Roman villa just under 2,000 years ago in what is now southern England.
A basketball-player-size wooden idol that allegedly escaped destruction by the Spanish conquistadors is real — but it may not be quite what people suspected. The statue is even older than thought, and may have been worshipped by the people who came before the Inca.
The rocky planets closest to the sun are made up of very different materials than the gas giants in the outer solar system. That’s because billions of years ago, our baby solar system was divided in two by a cosmic gatekeeper that prevented materials in the inner and outer regions from mixing.
The likely Leonardo da Vinci painting “Salvator Mundi” looks straightforward at first glance: a depiction of Jesus Christ in Renaissance-era clothing, raising one hand in blessing and holding a clear orb in the other.
Migrating animals that live in Earth’s oceans may have a closer relationship with the sun than we thought. New research shows that healthy gray whales are nearly five times more likely to strand when there is a high prevalence of sunspots, and therefore high levels of radio waves emitted from solar storms.
A gorgeous, incredibly detailed new image of the Milky Way’s center could help explain one of the enduring mysteries of our galaxy — why its heart is missing stars.
HONOLULU — Mysterious ultra-fast pinpricks of radio energy keep lighting up the night sky and nobody knows why. A newly discovered example of this transient phenomenon has been traced to its place of origin — a nearby spiral galaxy — but it’s only made things murkier for astronomers.
Archaeologists have found a Maya stone palace that dates to more than 1,000 years ago, according to the Mexican National Institute of Anthropology and History (INAH).
No one really knows what happens inside an atom. But two competing groups of scientists think they’ve figured it out. And both are racing to prove that their own vision is correct.
You’d have to be particularly unlucky to catch a cold and the flu at the same time, a new study finds.
A so-called all-male “holy mountain” in northern Greece has hosted Christian monasteries for nearly 2,000 years, with women strictly prohibited. But one woman may have somehow found a home there — at least in death.
SAN FRANCISCO — Rocks that seem to propel themselves across desert landscapes have long mystified and intrigued scientists. Now, researchers have identified tracks of these so-called sailing stones dating back about 200 million years, in a rocky slab long prized for the five early dinosaur footprints it preserved.
Thousands of years ago, a young Neolithic woman in what is now Denmark chewed on a piece of birch pitch. DNA analysis of this prehistoric “chewing gum” has now revealed, in remarkable detail, what she looked like.
Deep under Earth’s surface, earthquakes rumble in the mantle’s transition zone, the area that divides the upper mantle from the lower. Liquid in the mantle is thought to play a part in driving those deep earthquakes, but until now, no smoking gun could prove that fluid was present at those depths.
Far below the frozen cover of the Greenland ice sheet sprawls miles of bedrock — and extending through that bedrock for close to 1,000 miles is a valley that may contain a subterranean river, transporting water from central Greenland to the northern coast.
Scientists are scouring the remote Antarctic ice cap for rare meteorites chock-full of iron and holding secrets to the history of our solar system going back some 4.5 billion years.
Two piglets recently born in China look like average swine on the outside, but on the inside, they are (a very small) part monkey.
Inside a 2,200-year-old grave, archaeologists have discovered a stunning Iron Age shield, along with a chariot and two ponies buried in a leaping pose, in what archaeologists are calling one of the most important discoveries in the U.K.
A university student recently solved a question that’s puzzled physicists for over half a century: Why do gas bubbles appear to get stuck inside narrow vertical tubes? The answer may help explain the behavior of natural gases that are trapped in porous rocks.
