A prehistoric hidden cave and hippo bones found beneath a Welsh castle could transform understanding of ancient life in Britain, researchers said Thursday, calling the site a "once-in-a-lifetime discovery".

Previous small-scale excavations at Pembroke Castle have already uncovered evidence of early humans and animals, including a now extinct hippopotamus that roamed Wales 120,000 years ago.

A major five-year archaeological project led by the University of Aberdeen will investigate the "enormous" cave, accessed via a spiral staircase from the 11th Century castle, AFP reported.

"There is no other site like it in Britain -- it is a once-in-a-lifetime discovery," said Rob Dinnis, who will lead the project.

The cave, previously thought to have been emptied by the Victorians, is now described as "one of the most important prehistoric archives in Britain".

"Despite the limited work done so far, we can already say that Wogan Cavern is a truly remarkable site," Dinnis said in a statement.

"Not only is there extremely rare evidence for early Homo sapiens, there are also hints at even earlier human occupation, probably by Neanderthals."

"We have also found hippo bones, which probably date to the last interglacial period, around 120,000 years ago," he added.

Earlier finds have revealed bones of mammoth, woolly rhinoceros, reindeer and wild horse, alongside stone tools and evidence of human occupation across multiple periods.

With larger-scale excavation due to resume in May, the researchers hope to gain "insights into past climate change, extinct species, and the multiple periods when humans called the cave their home".

They said the site could chart a long sequence of human activity, from hunter-gatherers after the last Ice Age around 11,500 years ago to some of Britain's earliest Homo sapiens between 45,000 and 35,000 years ago, and possibly even earlier Neanderthal presence.

"Wogan Cavern provides a unique chance to use all the scientific techniques now available to archaeologists," said professor Kate Britton of the University of Aberdeen.

"Because the bones are well preserved, we can learn a lot about past environments and ecosystems," she added.

At Pembroke Castle, staff say the discovery adds a new dimension to the site's long history as a medieval fortress and birthplace of Henry VII in 1457.

"This is incredibly exciting news for everyone at the castle," said castle manager Jon Williams.

"We are thrilled that work on this wonderful cave will continue."

A brooch given to the first passenger to board a Dundee-built steamship 37 years before she sank has surfaced at an antiques roadshow.

The decorative item was presented to Elizabeth Anderson on April 21 1894, the date of the maiden voyage of the SS Citrine, according to the British website ‘itv News.’

Built by Dundee shipbuilders W B Thompson & Co, the Citrine was one of a number of vessels in the Glasgow-based “Gem line,” all of which were named after gemstones or minerals.

The shipping firm was owned by William Robertson, who started out with a single barge in 1852 before growing it into one of the largest coastal bulk shipping fleets in Britain.

The brooch was presented to Anderson by Robertson and is inscribed with the words “SS Citrine, April 21 1894, Elizabeth McIntyre Anderson, from William Robertson.”

The sides of the gold-colored item are shaped as a ship’s rope and its center has been designed as a life ring mounted with a citrine stone, echoing the name of the vessel.

The Citrine sank on March 17 1931 after striking rocks at Bradda Head, Port Erin, on the Isle of Man.

Accounts at the time described the ship’s final moments in darkness, heavy weather and confusion, and the disaster claimed the lives of nine of her 11 crew members.

William Robertson had been dead for 12 years by the time of the sinking but the business remained in family hands under his sons, William Francis Robertson and James Robertson.
The brooch was discovered at a WeBuyVintage roadshow in Fleetwood, Lancashire.

NASA on Tuesday is set to launch a daring robotic rescue mission, a long shot bid to prevent one of its aging telescopes from vanishing into dust.

If successful, the effort could pave the way for giving other satellites a second life.

The operation is set to last several months, kicking off with the launch of a robot designed to rescue the Swift space telescope that's currently falling towards Earth.

Without intervention, Swift is expected to soon burn up in the atmosphere.

The rescue spacecraft developed by the US startup Katalyst is slated to lift off Tuesday at 1023 GMT from a Pacific Ocean atoll aboard a small rocket named Pegasus.

The rocket-propelled launch vehicle will not take off from a launch pad. Instead, it will be released from a jet.

"Everything about this mission is so crazy," said NASA astrophysicist Regina Caputo with a laugh during an interview with AFP.

After it reaches an orbit near that of the telescope, the robot must locate Swift across the vastness of space.

The aim is then for the robot to maneuver around the telescope and latch on with three movable arms.

It will then vie to tow Swift into a stable orbit over the course of at least a month, rescuing it from destruction by moving it about 300 kilometers higher.

"This is a lot of firsts stacked on top of each other," said Shawn Domagal-Goldman, the director of NASA's astrophysics division, during a recent call with reporters.

"I'm just deeply thankful that we're even giving this a go."

The idea of such a rescue might seem odd at first glance.

The Neil Gehrels Swift Observatory telescope was launched in 2004, and was originally designed for a two-year mission.

The device was intended to study gamma-ray bursts, what Caputo called "the most energetic things that happen in the universe."

She likened it to a supercharged version of a supernova, which is a dramatic, explosive death of a star.

Gamma-ray bursts are extremely brief, she explained, so the telescope was placed at an altitude of approximately 600 kilometers in low Earth orbit, so it could remain in constant communication with researchers.

But with that pro came a con -- at such an altitude, the device without its own propulsion would eventually drift closer to Earth and burn up in the atmosphere.

Caputo said that phenomenon was expected and normal, because when the Sun is in its more active cyclical stages, it emits more particles and causes an expansion of Earth's atmosphere.

That creates drag, meaning satellites in low Earth orbit lose altitude.

Yet when forecasts in early 2025 indicated the telescope was nearing the end of its life, NASA began considering a possible rescue.

"We decided, yeah, we want to go save this one this time, because of how special it is," said Domagal-Goldman.

Despite its age, the Swift telescope remains in high demand within the scientific community, not least for its rapid response capabilities.

Should it burn up, it could not be immediately replaced.

The mission attempting unprecedented maneuvers has a projected cost of $30 million to save the device, which originally cost $250 million.

The rescue robot named LINK will have to overcome numerous challenges and unknowns.

For example, engineers do not have a clear picture of what the back of the telescope actually looks like -- even though that's where the robot must latch on.

With a laugh, Caputo projected the chances of success at "maybe 50-50."

Still, both NASA and the company Katalyst believe the mission -- which could run into the fall -- might pave the way for new possibilities in spacecraft management, and is worth a shot.

Robert Lamontagne, a vice president at Katalyst, said during a call with journalists that it could represent the "start of a new model" to "refuel, reposition, repurpose, repair, and even upgrade satellites, even if they were never prepared for it."

Scientists have stumbled on a rare dinosaur fossil from Antarctica, tucked away for decades in a drawer.

The bone comes from the tail of a long-necked, plant-eating dinosaur called a titanosaur. Scientists haven't yet identified the species it belongs to, The Associated Press reported.

It was discovered in 1985 during an expedition to Antarctica's James Ross Island and collected by geologist Mike Thomson. Working with the British Antarctic Survey, Thomson was mapping the area's rock layers and collected marine reptile fossils to help with future dating efforts. He recorded the find as a large reptile.

Decades later, paleontologist Mark Evans spotted the bone in the British Antarctic Survey's collections and wondered whether it might be a dinosaur.

He and other researchers analyzed the shape of the bone and compared it to other more complete dinosaur remains, confirming their discovery. The findings were published on Monday in the journal Acta Palaeontologica Polonica.

Dinosaur fossils are rare to find in Antarctica because of the unforgiving ice caps. But millions of years ago, when this dinosaur lived, the region was populated by lush forests — a “rather different and much more hospitable place than we think of today,” said study co-author Paul Barrett with the Natural History Museum in London.

At about 23 feet (7 meters) long, the dinosaur was small for its group and may have been young when it died. Scientists don't know how the creature met its end, but they think its body floated away from the coast and sank to the sea floor, becoming fossilized in marine rock.

Technology has come a long way since the dinosaur tail bone was first found, allowing researchers to peer inside bones and gain even more detailed information about ancient creatures. Thomson died in 2020 before the fossil was identified as belonging to a dinosaur.

“If he were still with us, he would be delighted to know what this was,” Evans, a study co-author, said.
