A giant meteorite boiled the oceans 3.2 billion years ago. Scientists say it was a ‘fertilizer bomb’ for life
гей секс порно

A massive space rock, estimated to be the size of four Mount Everests, slammed into Earth more than 3 billion years ago — and the impact could have been unexpectedly beneficial for the earliest forms of life on our planet, according to new research.

Typically, when a large space rock crashes into Earth, the impacts are associated with catastrophic devastation, as in the case of the demise of the dinosaurs 66 million years ago, when a roughly 6.2-mile-wide (10-kilometer) asteroid crashed off the coast of the Yucatan Peninsula in what’s now Mexico.

But Earth was young and a very different place when the S2 meteorite, estimated to have 50 to 200 times more mass than the dinosaur extinction-triggering Chicxulub asteroid, collided with the planet 3.26 billion years ago, according to Nadja Drabon, assistant professor of Earth and planetary sciences at Harvard University. She is also lead author of a new study describing the S2 impact and what followed in its aftermath that published Monday in the journal Proceedings of the National Academy of Sciences.

“No complex life had formed yet, and only single-celled life was present in the form of bacteria and archaea,” Drabon wrote in an email. “The oceans likely contained some life, but not as much as today in part due to a lack of nutrients. Some people even describe the Archean oceans as ‘biological deserts.’ The Archean Earth was a water world with few islands sticking out. It would have been a curious sight, as the oceans were probably green in color from iron-rich deep waters.”

When the S2 meteorite hit, global chaos ensued — but the impact also stirred up ingredients that might have enriched bacterial life, Drabon said. The new findings could change the way scientists understand how Earth and its fledgling life responded to bombardment from space rocks not long after the planet formed.

Greetings, earthlings! I’m Jackie Wattles, and I’m thrilled to be a new name bringing awe to your inbox.

I’ve covered space exploration for nearly a decade at CNN, and there has never been a more exciting time to follow space and science discoveries. As researchers push forward to explore and understand the cosmos, advancements in technology are sparking rapid developments in rocketry, astronomical observatories and a multitude of scientific instruments.

Look no further than the missions racing to unlock dark matter and the mysterious force known as dark energy, both so named precisely because science has yet to explain these phenomena.

Astronomers have never detected dark matter, but they believe it makes up about 85% of the total matter in the universe. Meanwhile, the existence of dark energy helps researchers explain why the universe is expanding — and why that expansion is speeding up.
Extraordinary new scientific instruments are churning out trailblazing data, ready to reshape how scientists view the cosmos.

A prime example is the European Space Agency’s wide-angle Euclid telescope that launched in 2023 to investigate the riddles of dark energy and dark matter.

Euclid this week delivered the first piece of a cosmic map — containing about 100 million stars and galaxies — that will take six years to create.

These stunning 3D observations may help scientists see how dark matter warps light and curves space across galaxies.

Meanwhile, on a mountaintop in northern Chile, the US National Science Foundation and Stanford University researchers are preparing to power up the world’s largest digital camera inside the Vera C. Rubin Observatory.

Unearthed
In the mountains of Uzbekistan, a research team used lasers strapped to a flying robot to uncover two cities buried and lost for centuries.

The anthropologists said they had mapped these forgotten medieval towns for the first time — located at a key crossroad of ancient silk trade routes — using a drone equipped with LiDAR, or light detection and ranging equipment.

When nature reclaims what’s left of once thriving civilizations, scientists are increasingly turning to remote sensing to peer through dense vegetation.

The images revealed two large settlements dotted with watchtowers, fortresses, complex buildings, plazas and pathways that tens of thousands of people may have called home.

Europe’s secret season for travel starts now
kraken официальный сайт

Summer might be the most popular season for tourism to Europe, but it hardly promises a calm, cool and collected experience.

Who can forget this summer’s protests against overtourism in Barcelona and Mallorca, the wildfires that raged across Greece during the country’s hottest June and July on record and selfie stoplights to help control crowds on the clogged streets of Rome and Florence?

For travelers looking to avoid all that — as well as break less of a sweat literally and financially — welcome to Europe’s secret season.

From roughly mid-October to mid-December, shoulder season for travel to Europe comes with fewer crowds, far more comfortable temperatures in places that skew scorching hot during the summer months and plunging prices on airfare and accommodation.

Plunging prices
“The cheapest time to fly to Europe is typically from about the middle point of October to the middle point of December,” said Hayley Berg, lead economist at travel platform Hopper. “Airfare prices during those eight or nine weeks or so will typically be about an average of 40% lower than prices in the peak of summer in June.”

Hopper’s data shows that airfare to Europe from the United States during the period between October 20 and December 8 is averaging between $560 and $630 per ticket — down 9% from this time last year and 5% compared to the same timeframe in 2019.

This teen became the youngest person to summit the world’s highest peaks. Now he wants others to follow in his footsteps

Nima Rinji Sherpa’s ears are still tinged black from wind chill, an occupational hazard of climbing to heights where humans struggle to breathe, and where the weather can turn deadly in an instant.

This month, Nima became the youngest person to summit all 14 of the world’s highest peaks, but the 18-year-old Nepalese mountaineer is already getting ready for his next big feat.

Speaking to CNN via video call from the Nepali capital Kathmandu last week, Nima said he’s taking a couple weeks’ rest before preparing to climb the world’s eighth-highest mountain, Manaslu, with Italian mountaineer Simone Moro – in winter, alpine-style.

“That means we’re climbing an 8,000-meter mountain in winter… There’s no fixed ropes for us, there’s no (supplemental) oxygen for us, there is no support for us. So, it’s like pure human endurance,” Nima said. “It has never been done in the history of mountaineering.”

After that, “I’ll take some rest,” Nima laughed.

On October 9, Nima reached the top of the 8,027-meter (26,335-foot) Shishapangma along with his partner Pasang Nurbu Sherpa. For Nima, it was the final of the “eight-thousanders,” the 14 peaks recognized by the International Climbing and Mountaineering Federation as standing more than 8,000 meters above sea level.

Describing the moment of summiting the final peak as “pure joy,” Nima said his motivation comes from his family, many of whom are renowned mountaineers.

His father, Tashi Lakpa Sherpa, has climbed Everest nine times, and at age 19 became the youngest person to summit without bottled oxygen. His uncle Mingma Sherpa became the first South Asian climber to summit the 14 peaks in 2011.

“My uncles and my father, they are way more successful than I would ever be because they came from a very small village. To even dream about being this successful, for them it was really hard,” Nima said. “I have the privilege that they didn’t have.”

Growing outside of Dearborn

During the day, Yemeni coffeehouses function similar to many neighborhood spots. Patrons host meetings, college students study and others pop in for a quick cup to-go.

But at night, they serve as de-facto living rooms, especially for young Muslims who don’t go to clubs and bar. From New York to Dallas, especially during the late nights of Ramadan, the crowd overflows into the street and you often have to yell to be heard inside. Some young Muslims even venture to the coffee shops in hopes of finding a life partner.

Nowhere is this coffeehouse culture more pronounced, and celebrated, than in Dearborn, Michigan, a suburb of Detroit and home to one of the largest Arab American communities in the United States.

Downtown Dearborn is peppered with different Yemeni coffee houses, which Howell said helped revitalize the Detroit area after the city became the largest municipality go to bankrupt in 2013. And it’s only growing.

“It’s become sort of contagious,” Howell said. “Several Yemeni entrepreneurs are opening coffee houses of their own, each with its own sort of style and atmosphere.”

The coffee chains have big ambitions beyond Dearborn. Qahwah House hopes to open another 20 to 30 locations in the next year, spanning across 12 states and Canada, Alhasbani said. They are also licensed out, but Alhasbani says he sets a high standard before agreeing to let anyone open a shop.

“We have too many people that come (asking me) they want to open. I have more than 10 different requests a day just to open this kind of business,” he said. “We don’t give anyone license until we make sure the person has the love for the brand and his mind and his heart in the Qahwah House.”
Another authentic Yemeni coffee chain, Haraz, also sees crowds of people throughout the day and night. They opened their first location in New York City last week — less than half a mile away from Qahwah House’s downtown Manhattan shop — and the franchisees plan to grow.
