Explanation: Have you ever thought about surfing on an alien world? We can now expand the search for the perfect wave from Earth to the rest of the Solar System, and beyond. Scientists have developed a new model for simulating waves on other planets. Titan is one of the 274 confirmed moons of Saturn to date, and the only object in the solar system (besides Earth) known to have liquid lakes and seas on its surface. The featured video shows a simulation of waves on Earth (right) and on Titan (left), under the same conditions (the scale marker is in...

A mineral long dismissed as worthless may be hiding something far more valuable. Scientists have found lithium inside pyrite, a discovery that could change how we think about future energy resources. Lithium is now central to modern technology. It powers phones, laptops, and electric cars, and its ability to store and release energy efficiently makes it essential for renewable energy systems. At the same time, demand is rising quickly. Most lithium still comes from pegmatites and volcanic clays, but expanding production without increasing environmental impact remains difficult. This is why researchers are exploring less obvious sources. Lithium Found Where No...

Computer scientist and futurist Ray Kurzweil believes humanity will achieve “longevity escape velocity” in just three years. The concept basically states that due to medical and technological advances, we will soon reach a point where our life expectancies lengthen by more than one year per year, effectively giving us time back on the clock. This is a very controversial concept, and one that—even if possible—would require widespread access to cutting edge medical technology. ============================================================================ Death and taxes—the twin inevitabilities of human life. At least, for the moment. If you ask some of the most prominent futurists in the world, death...

USS-Scorpion: Two Nuclear Torpedoes Still Sit 3,000 Meters Down — And Nobody Can Retrieve Them In May 1968, USS Scorpion vanished without warning in the Atlantic Ocean — taking 99 men and two nuclear torpedoes to the bottom. Found months later at 3,000 meters depth, the wreck has never been touched. Decades later, the cause of her sinking remains officially unsolved, and those warheads still sit on the ocean floor today. 40 Minute Video at link..................

In 1963, USS Thresher imploded at test depth killing all 129 aboard—the Navy blamed a "piping failure" and closed the case. But declassified documents from the 2000s revealed the submarine had over 800 documented defects before diving, whistleblower testimony proved inspectors were pressured to approve faulty welds, and acoustic analysis of the final moments shows the crew knew they were dying for nearly 5 minutes as water flooded in. The Navy knew Thresher wasn't safe, sent her down anyway, then spent 60 years hiding that 129 men died from institutional negligence, not accident. 26 Minute VIDEO AT LINK...............

They’ve hit the mother lode. We may no longer need to rely on foreign batteries to power our electronics. Geologists have announced that the Appalachian Mountains could be hiding a sprawling multi-billion-dollar cache of lithium that could last the US hundreds of years. “This research shows that the Appalachians contain enough lithium to help meet the nation’s growing needs,” declared US Geological Survey Director Ned Mamula in a statement. According to a map by the institution, this East Coast mountain range houses around 2.5 metric tons of this battery precursor, most of which is concentrated in the Carolinas, Maine and...

Explanation: No, Earth did not recently acquire six more moons! Today’s APOD is a combination of images following the Moon, Venus, and the Pleiades across a southern Sicilian sky as twilight turned to evening on April 19. From 2023 to 2029, the Pleiades' and the Moon “visit" each other once per month due to the Pleiades' location in the ecliptic plane. April 2026 saw the celestial alignment of their visit with Venus. About six stars in the Pleiades cluster (Messier 45) are typically visible with the unaided eye. Due to the cluster’s visibility across the world, there are many myths...

This has scientists quaking in their boots. Researchers have found that one of the US’s most dangerous fault lines is overdue for an earthquake, potentially threatening millions of people across California, per an alarming study in the journal Seismological Research Letters. This terrifying tremor could “cause extensive damage to such a dense population zone,” wrote the team from the Lawrence Livermore National Laboratory (LLNL) and Lawrence Berkeley National Laboratory (LBNL), in a statement. Part of the massive San Andreas Fault Line, the Hayward Fault Line extends 74 miles through major Bay Area hubs, including Berkeley, Oakland and Fremont, an area...

Opening day at Six Flags St. Louis ended early on Saturday with police on the scene. They were called after multiple brawls involving as many as 100 people, most of whom were juveniles, broke out at the park. This particular amusement park is one of seven properties that were recently sold by the main Six Flags company to a new owner, Enchanted Parks. There was apparently a need to set the tone early with the new ownership. Park guests weren’t going to be waiting around until the blistering heat of the middle of the summer, with scooters everywhere you turn...

Explanation: They're like mountain peaks, but they are forming stars. Bright-rimmed, flowing shapes gather near the center of this rich starfield toward the borders of the nautical southern constellations Puppis and Vela. Composed of interstellar gas and dust, the grouping of light-year sized cometary globules is about 1300 light-years distant. Energetic ultraviolet light from nearby hot stars has molded the globules and ionized their bright rims. The globules also stream away from the Vela supernova remnant which may have influenced their swept-back shapes. Within them, cores of cold gas and dust are likely collapsing to form low mass stars whose...

Well into Scotland this week and looking at Roman occupation, including one of the last physical signs of it, the truly remarkable Eagle Rock near Cramond. Now it normally raises some controversy in the comments whenever we acknowledge Roman control north of the wall, so we try to take a balanced view in this film: yes, parts of Scotland did fall for some periods - it's bonkers to deny that - but this site investigation shows how transitory it was. As well as the fantastic Eagle Rock, we explore the exposed remains of the Roman fort in Cramond - a...

The discovery of the lost Roman city of Briga in the forests of Normandy is a masterclass in persistence. For decades, experts doubted a significant city could exist in such a remote location, dismissing early finds as exaggerated. This video explores how archaeologists unearthed a massive 160-acre urban center, including a monumental sanctuary, a 5,000-seat theater, and a luxury basilica -- all hidden beneath the soil.

While the world hunts for the elusive Planet Nine, a new gravitational anomaly suggests something much closer is hiding in the dark. This gravitational warp doesn't align with a far-off gas giant, instead, the math points to an Earth-sized rocky planet lurking in the twilight. Something astronomers are calling Planet Y.

Explanation: Can you find the comet? Somewhere through this web of satellite trails is Comet C/2025 R3 (PanSTARRS), a bright visitor passing through the inner Solar System. Now, the orbiting satellites themselves only appear as streaks because of the long camera exposure, over 10 minutes in this case. On the contrary, to the eye, satellites appear as points that drift slowly across the night sky and shine by reflecting sunlight -- primarily just after sunset and before sunrise. The featured image was taken just before sunrise two weeks ago from Bavaria, Germany. Presently, Comet R3 PanSTARRS is hard to see...

The excavation of the Villa della Pisanella in Boscoreale has yielded one of the most extraordinary archaeological finds of the Roman era: the world's only known intact Roman boiler, complete with all its pipes, valves, and accessories. This unique artifact provides a fascinating insight into the technological sophistication of the ancient Romans, highlighting their advanced engineering skills and meticulous craftsmanship...The Villa della Pisanella first came to light in November 1868, when Modestino Pulzella, while laying the foundations for a new wall, discovered remnants of ancient structures. Further exploration revealed mosaics, but the work was soon halted by a neighboring landowner,...

“There is a silence in the night sky that has bothered me for as long as I can remember.” That line, attributed to Richard Feynman, lands because it gets at a simple, stubborn feeling. The sky looks full. Stars crowd the darkness. It seems reasonable to think someone else should be out there, and close enough to find. Yet the deeper physicists look into the laws that govern the universe, the more that silence starts to seem less like a cosmic riddle and more like a built-in feature of reality. Human intuition is not much help. It developed for ordinary...

In 2016, a routine excavation in a supermarket car park near Andover uncovered a grim secret—over 100 shallow graves filled with mostly young men, many brutally executed. Dating back to Anglo-Saxon England, the site reveals a hidden execution cemetery where individuals were hanged, beheaded, and discarded without ceremony. As archaeologists investigate, they uncover evidence of harsh medieval justice, social outcasts, and centuries of punishment stretching from Saxon to Norman times. This chilling discovery exposes a brutal world where law, power, and fear shaped life—and death—on the edges of society.

Both eruptions came from a sunspot region on the sun's western limb, AR4419. The first solar flare peaked at 9:07 p.m. EDT on April 23 (0107 GMT April 24), followed by the second at 4:14 a.m. EDT (0814 GMT) on April 24. These are the strongest solar flares we've seen in 78 days, according to solar physicist Ryan French. The bursts of radiation from the flares triggered strong radio blackouts on the sunlit side of Earth — the first affecting parts of the Pacific Ocean and Australia and the second impacting East Asia. The active sunspot region is putting on...

Explanation: Inside the head of this interstellar monster is a star that is slowly destroying it. The huge monster, actually an inanimate series of pillars of gas and dust, measures light years in length. The in-head star is not itself visible through the opaque interstellar dust but is bursting out partly by ejecting opposing beams of energetic particles called Herbig-Haro jets. Located about 7,500 light years away in the Carina Nebula and known informally as Mystic Mountain, the appearance of these pillars is dominated by dark dust even though they are composed mostly of clear hydrogen gas. The featured image...
