One of Antarctica’s strangest natural wonders has revealed another long-hidden secret. Scientists have, for the first time, explained how the famous Blood Falls periodically release iron-rich red water. The ancient brine has remained trapped beneath the ice for about 1.5 million years.

Blood Falls is located at Taylor Glacier in East Antarctica. The site has fascinated researchers for more than a century because bright red water occasionally flows from the glacier. The unusual stream makes the ice appear to bleed. Scientists already knew why the water was red. Until now, however, they did not fully understand how the ancient brine escaped from deep beneath the glacier.

The strange opening roughly the size of a small swimming pool, the newly formed hole was nowhere to be seen during the previous inspection. Its sudden appearance has surprised geologists and sparked a fresh investigation into Yellowstone’s constantly changing geothermal landscape. It is the second major hydrothermal event recorded in Biscuit Basin within the past two years.

On the night of Saturday, July 4, units of the Ukrainian Unmanned Systems Forces launched a strike on Russia's Leningrad Oblast. One of the targets was the Saint Petersburg oil terminal. The main base of the Russian Baltic Fleet's Leningrad naval base, Kronstadt, was also struck.

Researchers in the Netherlands have completed another stage of studying a skeleton. The findings have brought them closer to an answer, but the identity of the man remains uncertain.

Scientists say they cannot confirm that the remains belong to Charles de Batz de Castelmore, better known as d’Artagnan. However, they also cannot rule out that possibility. Several discoveries continue to match historical records surprisingly well.

Russian soldiers need to surrender ahead of time, because in the final moments before a drone strike or munitions drop, there may simply not be enough time.

Capturing the enemy with a drone designed to destroy manpower is an extremely difficult task.

Every time a pilot manages to force the enemy to lay down their arms and surrender, it demonstrates the high skill of Ukrainian drone operators.

Researchers hacked through more than three miles of vegetation to get to the site, which lies out of bounds of familiar logging tracks. There, they found unique carved stelae and altars. Archaeologists discovered an ancient Maya city that was hidden in the Mexican jungle for more than a millennium. Located in the Calakmul Biosphere Reserve in Campeche, at the base of the Yucatán Peninsula, the city is uniquely intact.

What would happen if Earth received a real message from an extraterrestrial civilization? Under updated SETI recommendations, no reply should be sent until the discovery has been verified and discussed internationally.

The International Academy of Astronautics (IAA) has revised its first-contact guidelines for the first time since 2010. The changes reflect major advances in astronomy, radio telescopes, artificial intelligence, and the search for extraterrestrial intelligence.

The updated document focuses on one simple idea. If researchers detect what appears to be a genuine alien signal, they should not rush to answer it. Instead, the evidence should first be carefully checked and independently confirmed.

For over 20 years, a team of scientists led by Professor Dariusz Polinski of the Nicolaus Copernicus University in Toruń has been excavating near the village of Peń.

One of the most striking sites is an unmarked cemetery containing the remains of approximately 100 local residents.

According to Professor Polinski, at least 12 of the burials were made in a special ritual manner. This may be the largest cluster of “anti-vampire” graves in Poland.

One of the American military heard a long, unusual scream, then smelled smoke coming from beneath the trees. Advancing, the group discovered the remains of a destroyed robotic ground vehicle. Moments later, they heard the voices of wounded Ukrainian soldiers calling for help.

Operators of Ukrainian drones struck an enemy pickup truck carrying numerous Russian infantrymen in its bed. Ukrainian drone catching up to the vehicle; the Russian occupiers notice it but don’t even have time to try to jump out.

The mission depends on an unusual launch method. Instead of a normal rocket launch from the ground, NASA will use the Pegasus XL, an air-launched rocket system carried under a large aircraft.

The Swift observatory has been in space since 2004. It is mainly used to study gamma-ray bursts — extremely powerful explosions that happen far away in the universe. Over time, the spacecraft has slowly been dropping lower because of atmospheric drag.

536 AD may have been the darkest and most devastating year in human history. Historians and climate scientists believe it marked the beginning of a global crisis. The disaster affected millions of people across Europe, Asia and parts of the Middle East.

For nearly a year and a half, much of Europe and parts of Asia were covered by a mysterious veil that blocked sunlight. Daylight became unusually dim. Average temperatures dropped by almost 2.5°C (4.5°F). Crops failed across vast regions.

Having received information about enemy movements, the Ukrainian paratrooper took up position and waited until they approached close range. When three Russian occupiers entered the shelter, he immediately attacked them with a fragmentation grenade and opened fire with small arms.

With the Arctic losing more and more summer ice every year, scientists have launched an unusual field experiment. At first glance, it seems more like science fiction than climate science.

The project was led by Real Ice, with support from the UK government. The idea was simple: during the Arctic winter, seawater was pumped to the surface, and nature did the rest.

After freezing, the water formed a thicker layer of ice, which could persist longer into the warmer months.

Professor José Miguel Soriano del Castillo argues that Earth could look less like a giant buffet and more like a dangerous place filled with unfamiliar chemicals and microorganisms.

The professor believes many popular ideas from science fiction are far from realistic. Hollywood often shows friendly aliens enjoying human food or sweets. In reality, extraterrestrial visitors might have no interest in anything we normally eat.

The brazen Russian occupier unfurled his flag and began posing for a photo. But a Ukrainian drone flew in to help him with the photo.

One of Britain’s most famous trees has reached the end of its remarkable life. The legendary Major Oak, better known as the Robin Hood Oak, has officially died after failing to produce new leaves for the first time in its long history.

For generations, visitors have traveled to Sherwood Forest to see the enormous oak linked to the legend of Robin Hood. Whether the famous outlaw ever stood beneath its branches remains unknown. Even so, the tree became one of England’s best-known natural landmarks.

Declassified NASA documents contain a reference to an extraterrestrial base on the Moon near the Van de Graaff crater. An audio recording of a secret NASA meeting that took place after the Apollo 16 mission in 1972.

During the conversation, the topic initially turned to a “huge hole” near the Van de Graaff crater on the far side of the Moon. Then one of the participants said, “It could be an alien star base or something. Anyway, the next slide shows the front side of the moon.”

Few pirates left a mark on history quite like Henry Every. He vanished more than 300 years ago. Now archaeologists believe they may have found the remains of his famous ship near the Bahamas.

The discovery was made off the coast of Nassau. Today, the area attracts tourists and divers from around the world. More than three centuries ago, however, these waters were linked to pirates, smugglers and privateers.

Getting to the wreck was not easy. The waters around the site are known for large sharks. Team members said several predators were already circling the boat. They spotted them before the first dive even began.

Footage shared by Ukraine's 79th Air Assault Brigade shows a Ukrainian soldier coming face to face with three Russian assault troops during combat operations on the eastern front. Despite being outnumbered, he held his position and engaged the attackers in a close-range firefight, ultimately eliminating all three.
