Scientists have identified the source in the sun which produces solar energetic particles that threaten crewed spaceflight, near-Earth satellites and airplanes.

According to The Daily Mail, a team of US researchers analyzed the composition of particles that flew towards Earth in 2014 and found the same 'fingerprint' of plasma that is located low in the sun's chromosphere - its second most outer layer.

The solar energetic particles are released from the sun at high speed during storms in its atmosphere and for the first time scientists have identified their source.

The team behind the new study said this new information can be used to better predict when a major solar storm will hit and act faster to mitigate the risks.

"We need to understand and characterize the processes that form and heat the solar atmosphere and accelerate the solar wind into the heliosphere," reads the study published in the Science Advances journal.

"From a space weather perspective, we must elucidate the mechanisms that drive solar flares, coronal mass ejections (CMEs), and solar energetic particles (SEPs)," the researchers explain.

In the study, researchers used measurements from NASA's Wind satellite, located between the sun and Earth, to analyze a series of solar energetic particle streams, each lasting at least a day, in January 2014.

These results were then compared to spectroscopy data from the Hinode spacecraft, which explores the magnetic fields of the sun to uncover what powers the solar atmosphere and sparks solar eruptions.

The 2014 high-energy particles came for a highly active region of the sun that frequently gives off solar flares and CMEs, and an extremely strong magnetic field.

"These energetic particles, once released, are then accelerated by eruptions that travel at a speed of a few thousand kilometers a second," said Stephanie Yardley from the UCL Mullard Space Science Laboratory.

The area, dubbed 11944, was one of the largest active regions on the Sun at the time and was visible to observers on Earth as a sunspot—a dark spot on the surface of the sun.

Olympic Tourists in Cortina Can Explore the Dolomites with the New ‘Uber Snowmobile’ Service

For one month starting on Saturday, Olympic spectators keen for a side trip to a UNESCO World Heritage Site can use Uber to reserve a ride on a snowmobile along the snow-covered road to the base of the Three Peaks of Lavaredo.

The dramatic, jagged limestone pinnacles stand just 23 kilometers (14.3 miles) from the Cortina venues where athletes are competing in the 2026 Winter Olympics and Paralympics.

One of the Olympic torchbearers, Giulia Baffetti, runs snowmobiling tours through Cortina-based winter activities outfit Snowdreamers. The company partnered with Uber, the official ride-hailing sponsor for the Games, to offer free tours on the weekends in February to people in town.

"Uber Snowmobile" tours, which can only be booked through Uber, include a ride in an Uber transfer bus for up to eight people from Cortina to the spot where riders mount their snowmobiles for departure. Tourgoers then follow the instructor, who leads the line of snowmobiles.

The first slots offered went fast, but Uber spokesperson Caspar Nixon said Friday that it planned to add more.

The three peaks are a magical place, Baffetti said, and this is a way for more people to experience it. Hikers and climbers flock there in the warmer months. In the winter, it’s a prime spot for cross-country skiing, snowshoeing and sledding. Snowmobiling is allowed in a limited area in order to protect the environment.

"We want to give an experience to the tourists, so they can feel the mountains in a different way," she said.

The Associated Press took the one-hour tour on Thursday, ahead of the Saturday launch, along with one other person. Helmets are essential, while heated handgrips are a most welcome feature. And that red button? Passengers can push it to stop the snowmobile if it veers off course or they feel unsafe.

The adrenaline-filled ride reaches speeds up to 40 kph (25 mph) when zooming past snow-covered trees, and drivers are instructed to slow when coming upon cross-country skiers and sledders. Deer and wolves are sometimes seen along the 7-kilometer (4.3-mile) route up to the base of the peaks.

Also visible on Thursday was the southernmost of the three Lavaredo peaks, rising sharply out of the fog. While the Dolomites are breathtaking from Cortina — and on Friday, the sun shone and the view was clear from town — they are even more impressive up close.

The route back includes a short loop around Lake Antorno. Before traversing all the ups and downs, the snowmobile instructor leading the tour offers a reminder about that red button.

Saher Deeb, an Israeli tourist, was along for the ride Thursday, one day after his 29th birthday. It was his first time on a snowmobile, and he was all smiles as he climbed off at the end.

"It was perfect," he said.

Two French adventurers reached the end of an epic walk from France to Shanghai on Saturday, after nearly a year and a half crossing 16 countries almost entirely on foot.

Loic Voisot and Benjamin Humblot embraced as they stood by the river on the Bund promenade, the financial hub's distinctive skyline glittering in the background.

Voisot and Humblot set off from Annecy in September 2024.

"We were thinking about this moment almost every day for more than a year now, so it's a really strong feeling," Humblot said of reaching their destination.

Hanging out after work one day, the two friends realized they both yearned for a "great adventure".

They wanted to visit China -- but without flying, which they believe is too harmful to the environment.

A plan to set out on foot was hatched, and except for a stretch in Russia which was done by bus for safety reasons, 518 days and around 12,850 kilometers (7,980 miles) later they took the last steps to completing it.

Around 50 people gathered at the start point for the last 10km stretch of their odyssey, many local people who have been following them on social media.

Along the way their numbers swelled, as media, French residents of Shanghai and others joined.

"If your dreams are crazy, just take it step by step and sometimes you will not succeed, but sometimes you will," said Voisot.

Asked what he would do first now the walk was over, he joked: "Sleep a lot!"

A soft layer of white snow blankets the grounds of the Chicago Botanic Garden. The air is chilly, the sky gray.

Inside, however, the air is warm and lights illuminate more than 10,000 vividly colored orchids. Staff members move in and out of greenhouses, preparing to open the garden’s 12th annual Orchid Show on Saturday.

This year’s theme is “Feelin’ Groovy" with several installations calling back to the 1970s, including a yellow Volkswagen Beetle filled with orchids.

“It’s just a really great way to get out of the winter cold and come into our greenhouses,” said Jodi Zombolo, associate vice president of visitor events and programs. “I think people are really looking for something to kind of bring happiness and something that they will enjoy and find whimsy in.”

The orchid family is one of the largest in the plant world and some of the species in the show are rare, exhibits horticulturist Jason Toth said. One example is the Angraecum sesquipedale, also known as Darwin’s orchid, on display in the west gallery.

Toth said the orchid led Darwin to correctly conclude that pollinators have adapted in order to reach down the flower's very long end.

"It has a great story and it’s quite remarkable-looking,” said Toth.

Elsewhere, massive, gnarly roots dangle from purple, pink and yellow Vanda orchids in the south greenhouse. These epiphytic orchids grow on the surface of trees instead of in soil.

“I think everyone’s tired of the winter,” said Toth. “So having some kind of flower show at this point is what we’re all craving. And 'Orchids' fits the bill.”

The show is expected to draw 85,000 visitors this year.
