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...

In the ancient Mitanni Kingdom, an Indo-Aryan language very closely related to Sanskrit was used by the ruling class -- but only for very special occasions... Jack of All Languages explores the surprising linguistic links between ancient Indo-Aryan terms found in Syrian horse training manuals and early Sanskrit. By analyzing archaeological tablets and royal treaties, this investigation sheds light on how a prestige language influenced elite cultures in the Middle East centuries before the oldest known Vedic texts were composed.

California drivers could be seeing lower gas prices once a new mega-pipeline project reaches completion, flooding the state with the much needed black gold. In a recent joint announcement, Phillips 66 and Kinder Morgan, Inc. said its Western Gateway Pipeline project was moving forward following the closure in the state of multiple refineries. “Customer response during the open season underscores the importance of Western Gateway in addressing long‑term refined products logistics needs in the region,” Phillips 66 Chairman and CEO Mark Lashier said. Once fully operational, the massive pipeline will stretch from St. Louis, MO. to California, and be able...

Explanation: This seaside sunset offered a surreal experience, captured in a sea and skyscape from the west coast of Sardinia, Italy, planet Earth. The Daliesque scene is a composition of sequential exposures made with a camera and long telephoto lens. The Sun is not melting, though. Its shifting and fluid appearance as it nears the horizon is caused as refraction along the line of sight changes and creates distorted images or mirages of the reddened solar disk. The changes in atmospheric refraction correspond to atmospheric layers with sharply different temperatures and densities. Another famous but fleeting effect of atmospheric refraction...

We Might Be Wrong About Humanity's Near Extinction | 34:00 New Scientist | 484K subscribers | 330,045 views | April 8, 2026

Once the epicenter of a catastrophic nuclear disaster, Chernobyl in Ukraine was left uninhabitable for humans. But in the silence that followed evacuation, nature began to reclaim the land. Przewalski's horses, once nearly extinct, now roam freely, grazing among overgrown buildings as forests reclaim old roads. Wolves, lynx, moose, and red deer have also returned, along with free-roaming dogs and even brown bears, a species absent from the region for more than a century. Still, the recovery is not without complications. Radiation remains an invisible presence, and scientists continue to observe its subtle but lasting effects, such as birds developing...

Explanation: Sunlit arms of a crescent moon seem to embrace the faint lunar night side in this dramatic celestial view from planet Earth. The single telephoto exposure tracking the sky was captured on the night of April 19, when a two day old Moon was near perigee in its elliptical orbit. On that date, the young Moon was also close on the sky to the lovely Pleiades Star Cluster. With the moonlight dimmed by clouds the Pleiades sister stars gather below the Moon's bright crescent, seen through a faint but colorful lunar corona. The lunar night side is illuminated by...

Deep-diving robots help crack the mystery of Antarctica’s vanishing sea ice Something strange has been swirling in the waters around Antarctica. From the 1970s until a decade ago, the floating sea ice that radiates from the continent had been expanding, even with climate change already in full swing. Then, in 2016, it suddenly and dramatically contracted — and has yet to recover — as rising global temperatures seemed to catch up with the Southern Ocean. Far from being just a local issue, the loss of sea ice has huge implications for Antarctica’s vast ice sheet, which would drive sea levels...

Ibiza became part of the Islamic world in the year 902, when it was conquered by the Umayyad Emirate of Córdoba. Settlement followed rapidly, taking place within little more than a generation, and by the twelfth century the island had developed into a modest but active urban centre within al-Andalus.Positioned along key maritime routes, Ibiza was not an isolated outpost but part of a dynamic network linking Iberia, North Africa, and the wider Mediterranean. This broader context helps explain the striking diversity uncovered in the new study, published in Nature Communications.The research team analysed 13 individuals buried between the tenth...

New examination of artifacts recovered from a tomb discovered in 1927 near the Etruscan site of Bisenzio suggests that luxury materials from the western Mediterranean were traded in the interior of the Italian peninsula, according to a report in La Brújula Verde. Located in central Italy's necropolis of Olmo Bello, the rectangular stone cist contained cremated remains, weapons, and ceramics dated to between 750 and 725 B.C. Andrea Babbi of Italy's Institute of Heritage Science said that one of these artifacts, a bronze brooch, had been wrapped with a thin, ornamental silver wire shaped by a series of grooved rollers....

It was more than it was Kraken-ed up to be. An octopus the size of the Hollywood Sign might seem like a monster from Greek mythology. However, new fossil evidence reveals that massive “kraken”-like cephalopods ruled the seas during the Cretaceous period, possibly preying on massive sea reptiles and other so-called apex predators, per a study published Thursday in the American Association for the Advancement of Science. This massive mollusk “had among the largest body sizes of all organisms in the Cretaceous oceans,” wrote the researchers, who hailed from Hokkaido University. Indeed, at 62-feet-long, this colossal octopus could grow up...

According to a Greek Reporter article, a collection of Bronze Age jewelry was discovered in northern Germany during the construction of a wind farm. The cache was lifted with surrounding soil from the site for excavation under laboratory conditions by researchers from the Lower Saxony State Office for Monument Preservation. The 3,000-year-old neck collars, arm spirals, sheet metal ornaments, and disc pins are thought to have belonged to at least three women. One necklace was made with more than 150 amber beads. The valuable deposit, which is known as the Ahlum Hoard, is thought to have been buried by local...

On April 26, 1986, Chernobyl Nuclear Power Plant near Pripyat, Ukraine, exploded—a combination of poor reactor design and serious mismanagement had caused the worst nuclear disaster in human history. Fast forward 40 years, and things have changed. While the horrific death, illness, and environmental degradation caused by the meltdown will never be completely forgotten, the area surrounding Chernobyl has come to provide a rare scientific opportunity. Today, it is a living laboratory for scientists exploring questions (many of them genetic) regarding long-term exposure to high levels of radiation. Frogs, for example, have adapted darker skin colors to protect against radiation....
