Siberia's 'Gateway to Hell' crater fuels new fears

29 November 2024 at 06:00

In the remote reaches of Siberia, a colossal scar on the Earth's surface is expanding at a breathtaking pace, swallowing up the frozen landscape and potentially unleashing ancient threats. The Batagaika crater, aptly nicknamed the "Gateway to Hell," is not just a geological curiosity, it's a stark reminder of the rapid changes our planet is undergoing.

Imagine a gash in the Earth so large you could fit several football stadiums inside it. That's the Batagaika crater for you. This massive thermokarst depression – a fancy term for a giant permafrost-thaw sinkhole – is growing at an astonishing rate of 35 million cubic feet each year. To put that into perspective, it's like carving out a small town's worth of earth annually. Currently stretching about 0.6 miles long and 0.5 miles wide at its widest point, this behemoth shows no signs of slowing down. In fact, it's speeding up, driven by a vicious cycle of warming temperatures and melting ice. This study was published in theΒ journal Geomorphology.

IS THIS SPACE CAPSULE HOW WE WILL LIVE, WORK IN ORBIT IN FUTURE?

Despite its name, permafrost isn't actually permanent. It's ground that's remained at or below freezing for at least two years. When this frozen soil thaws, it can't support the weight above it, leading to collapse and the formation of these massive "slumps." The Batagaika crater is a prime example of this process in overdrive. As the permafrost melts, it exposes more soil to sunlight, which then melts more permafrost. It's a feedback loop that's difficult to break, especially in our warming world.

While the sheer size of the Batagaika crater is impressive, what's truly mind-boggling is its depth, both physical and temporal. The steep walls of this mega-slump reveal permafrost layers estimated to be 650,000 years old. That's older than our species. But with ancient ice comes ancient dangers. Scientists have already revived a 48,500-year-old "zombie virus" from Arctic permafrost, and there's concern about what other long-dormant pathogens might be awakening. It's not just a plot from some sci-fi movie anymore. It's a real consideration for modern science and medicine.

The Batagaika crater isn't just releasing potential pathogens. It's also unleashing a significant amount of carbon into the atmosphere. According to recent studies, this single mega-slump is responsible for releasing 4,000 to 5,000 tons of organic carbon every year. That's equivalent to the annual emissions of about 1,000 cars. This release of carbon, previously locked away in the frozen ground, further contributes to global warming, potentially accelerating the very process that created the crater in the first place.

The Batagaika crater, while extreme, is not unique. It represents a process happening across the Arctic and sub-Arctic regions. As our planet continues to warm, more of these massive permafrost thaw features are likely to appear. While some might see the crater as a tourist attraction – and indeed it has become one – it's crucial to recognize it as a warning sign. The "Gateway to Hell" is more than just a catchy nickname; it's a portal into a possible future where rapid environmental changes reshape our world in ways we're only beginning to understand. The question remains: Will we heed the warning signs and take action, or will we continue to watch as more gateways open across our warming world?

Dark matter may be behind wobble in Mars’ orbit, study suggests

23 September 2024 at 21:57

A study published last week proposed that dark matter may be responsible for an observable wobble in Mars’ orbit.

The study, published in the peer-reviewed scientific journal Physical Review, postulates the theory that dark matter compromises microscopic, or primordial, black holes.

Unlike astrophysical black holes, these primordial black holes formed when dense pockets of gas collapsed in the seconds after the Big Bang and scattered throughout the universe because of expansion.Β 

Despite being as small as an atom, these primordial black holes would be heavier than thousands of solar masses and constitute dark matter.Β

First theorized in the 1930s by Swiss astronomer Fritz Zwicky, dark matter is a form of matter undetectable to the human eye. It does not emit light or energy but makes up roughly a quarter of the universe’s mass. Researchers have proposed its existence based on the gravitational pull on other visible matter.

The new study, "Close encounters of the primordial kind," theorizes that dark matter, made up of primordial black holes, is pushing Mars’ orbit slightly off track because of its extreme mass.

The researchers, comprising MIT physicists, backed up their theory with a simulation of Mars’ orbit which aligned with their proposal.Β

The researchers theorized that these primordial black holes would introduce a wobble into Mars' orbit at least once per decade during zooms through the solar system.

Astronomers can detect such a wobble thanks to advances in telemetry, or measuring the distance between planets.Β 

"We’re taking advantage of this highly instrumented region of space to try and look for a small effect," said co-author and physics professor David Kaiser. "If we see it, that would count as a real reason to keep pursuing this delightful idea that all of dark matter consists of black holes that were spawned in less than a second after the Big Bang and have been streaming around the universe for 14 billion years."

New dinosaur species similar to T. rex found in Asia: 'One of the most significant' discoveries

25 August 2024 at 07:00

A new carnivore has come to town β€” 165 million years ago at least.Β 

The Alpkarakush kyrgyzicus, a new species and genus of theropod dinosaur, has been discovered in Kyrgyzstan by an expedition team of German and Kyrgyz researchers, according to the Bavarian State Natural History Collections in Germany.Β 

Alpkarakush kyrgyzicus is the first theropod dinosaur found in Kyrgyzstan and the "find is one of the most significant in Central Asia," the institution said in a news release.Β 

Before the new species' discovery, no large Jurassic predatory dinosaurs had been known to live in the area around Kyrgyzstan between Central Europe and Eastern Asia, according to the institution.Β 

DINOSAUR-KILLING ASTEROID LIKELY CAME FROM BEYOND JUPITER, STUDY FINDS

The first fossils of Alpkarakush kyrgyzicus were uncovered in 2006 by Kyrgyz paleontologist Aizek Bakirov in a mountainous desert area of the country near the city of Tashkumyr.

Between 2006 and last year, more fossils, including skull bones, pelvic vertebrae and forearms, were found.Β 

The dinosaur is believed to be around 30 feet long.

"Particularly impressive is its extremely protruding β€˜eyebrow’ on the so-called postorbital bone, a skull bone behind the eye-opening, which indicates the presence of a horn at this point," the institution said. "Other unique features are found on the dorsal vertebrae and the femur."

Alpkarakush kyrgyzicus and Tyrannosaurus rex (T. rex) were both theropods β€” although T. rex lived later during the Cretaceous period and in different parts of the world β€” dinosaurs who walked on strong back legs and had shorter front limbs. Modern-day birds evolved from theropods.Β 

NEWLY DISCOVERED DINOSAUR SPECIES IS ONLY GREEN FOSSIL EVER FOUND, TO BE DISPLAYED IN LA

Professor Oliver Rauhut of the Bavarian Collection of Paleontology and Geology in Munich, who was a first author of the study published in the Zoological Journal of the Linnean Society, said in a statement: "This discovery closes a huge gap in our knowledge of the Jurassic theropods. It leads us to important new insights into the evolution and biogeography of these animals."Β

A smaller, juvenile Alpkarakush kyrgyzicus specimen was found at the site along with the adult dinosaur, leading researchers to believe it may have been a parent and child.Β 

Alpkarakush kyrgyzicus is named for a mythological KyrgyzΒ bird called Alpkarakush that often aids heroes in critical moments and for being found in the Kyrgyz Republic.Β
