Is there anywhere else in our solar system that could support life? An imposing NASA probe is due to lift off on Monday on a five-and-a-half-year journey to Europa, one of Jupiter's many moons, to take the first detailed step toward finding out.

The Europa Clipper mission will allow the US space agency to uncover new details about the moon, which scientists believe could hold an ocean of liquid water beneath its icy surface.

Liftoff is scheduled for "no earlier than" Monday, October 14, from Cape Canaveral in Florida aboard a powerful SpaceX Falcon Heavy rocket, NASA said in a statement.

"Europa is one of the most promising places to look for life beyond Earth," said NASA official Gina DiBraccio at a news conference last month.

The mission will not look directly for signs of life but will instead look to answer the question: Does Europa contain the ingredients that would allow life to be present?

If it does, another mission would then have to make the journey to try and detect it.

"It's a chance for us to explore not a world that might have been habitable billions of years ago," like Mars, Europa Clipper program scientist Curt Niebur told reporters last month, "but a world that might be habitable today, right now."

The probe is the largest ever designed by NASA for interplanetary exploration.

It is 30 meters wide when its immense solar panels -- designed to capture the weak light that reaches Jupiter -- are fully extended.

- Primitive life? -

While Europa's existence has been known since 1610, the first close-up images were taken by the Voyager probes in 1979, which revealed mysterious reddish lines crisscrossing its surface.

The next probe to reach Jupiter's icy moon was NASA's Galileo probe in the 1990s, which found it was highly likely that the moon was home to an ocean.

This time, the Europa Clipper probe will carry a host of sophisticated instruments, including cameras, a spectrograph, radar, and a magnetometer to measure its magnetic forces.

The mission will look to determine the structure and composition of Europa's icy surface, its depth, and even the salinity of its ocean, as well as the way the two interact -- to find out, for example, if water rises to the surface in places.

The aim is to understand whether the three ingredients necessary for life are present: water, energy and certain chemical compounds.

If these conditions exist on Europa, life could be found in the ocean in the form of primitive bacteria, explained Bonnie Buratti, the mission's deputy project scientist.

But the bacteria would likely be too deep for the Europa Clipper to see.

And what if Europa isn't habitable after all? "That also opens up a whole wealth of questions: Why did we think this? And why is it not there?" said Nikki Fox, an associate administrator at NASA.

- 49 flybys -

The probe will cover 2.9 billion kilometers (1.8 billion miles) during its journey to Jupiter, with arrival expected in April 2030.

The main mission will last another four years.

The probe will make 49 close flybys over Europa, coming as close as 25 kilometers (16 miles) above the surface.

It will be subjected to intense radiation -- the equivalent of several million chest x-rays on each pass.

Some 4,000 people have been working on the $5.2 billion mission for around a decade.

NASA says the investment is justified by the importance of the data that will be collected.

If our solar system turns out to be home to two habitable worlds (Europa and Earth), "think of what that means when you extend that result to the billions and billions of other solar systems in this galaxy," said Niebur, the Europa Clipper program scientist.

"Setting aside the 'Is there life?' question on Europa, just the habitability question in and of itself opens up a huge new paradigm for searching for life in the galaxy," he added.

The Europa Clipper will operate at the same time as the European Space Agency's (ESA) Juice probe, which will study two other moons of Jupiter -- Ganymede and Callisto.

Orange Frog Size of Pencil Tip Discovered in Brazil Forests

Scientists have found a new orange toad species in Brazil that is so small it fits on the tip of a pencil, highlighting the need for more conservation efforts in the country’s mountainous forest areas.

The toad species, measuring less than 14mm, was found deep in the cloud forests of the Serra do Quiriri mountain range in the southern Brazilian Atlantic Forest, according to the Independent.

Researchers have named the new species Brachycephalus lulai in honor of Brazil’s president Luiz Inacio Lula da Silva.

Cloud forests typically are found at altitudes between 1,000 and 2,500m and a layer of clouds at the canopy level is common year-round.

Until now, around two million animal species have been discovered in the world, with estimates suggesting that the Earth is home to around eight million of them, meaning at least six million remain yet undiscovered.

For decades, researchers have been combing the southern Brazilian Atlantic Forest to find and catalogue new species.

The region is known to be home to micro-endemic frogs and toads that are only found in small, restricted areas of the forest and are vulnerable to extinction.

In the latest study, researchers document the discovery of tiny frogs with a striking orange body and distinctive green and brown freckles.

The males were found to measure between 9 and 11mm, and females between 11 and 14mm.

They are among the smallest four-legged animals on Earth, capable of fitting fully on the tip of a pencil, researchers say.

Scientists identified the new species by its unique mating call, consisting of two short bursts of sound, unlike those of other known Brachycephalus in the area.

Researchers also conducted CT X-ray scans to look at the skeletal structure and DNA analysis to confirm what they had was indeed a new species.

Comparing DNA samples of the toad with those of other species, they found that it is most closely related to two species that live in the Serra do Quiriri.

Following the discovery, scientists immediately called for conservation efforts to protect the toad species and its relatives.

“Through this tribute (the act of naming a new species), we seek to encourage the expansion of conservation initiatives focused on the Atlantic Forest as a whole, and on Brazil's highly endemic miniaturized frogs in particular,” researchers wrote in the study published in the journal PLOS One.

'Extremely Exciting': The Ice Cores that Could Help Save Glaciers

Dressed in an orange puffer jacket, Japanese scientist Yoshinori Iizuka stepped into a storage freezer to retrieve an ice core he hopes will help experts protect the world's disappearing glaciers.

The fist-sized sample drilled from a mountaintop is part of an ambitious international effort to understand why glaciers in Tajikistan have resisted the rapid melting seen almost everywhere else.

"If we could learn the mechanism behind the increased volume of ice there, then we may be able to apply that to all the other glaciers around the world," potentially even helping revive them, said Iizuka, a professor at Hokkaido University.

"That may be too ambitious a statement. But I hope our study will ultimately help people," he said.

Thousands of glaciers will vanish each year in the coming decades, leaving only a fraction standing by the end of the century unless global warming is curbed, a study published in the journal Nature Climate Change showed Monday.

Earlier this year, AFP exclusively accompanied Iizuka and other scientists through harsh conditions to a site at an altitude of 5,810 meters (about 19,000 feet) on the Kon-Chukurbashi ice cap in the Pamir Mountains.

The area is the only mountainous region on the planet where glaciers have not only resisted melting, but even slightly grown, a phenomenon called the "Pamir-Karakoram anomaly.”

The team drilled two ice columns approximately 105 meters (328 feet) long out of the glacier.

One is being stored in an underground sanctuary in Antarctica belonging to the Ice Memory Foundation, which supported the Tajikistan expedition along with the Swiss Polar Institute.

The other was shipped to Iizuka's facility, the Institute of Low Temperature Science at Hokkaido University in Sapporo, where the team is hunting clues on why precipitation in the region increased over the last century, and how the glacier has resisted melting.

Some link the anomaly to the area's cold climate or even increased use of agricultural water in Pakistan that creates more vapor.

But the ice cores are the first opportunity to examine the anomaly scientifically.
"Information from the past is crucial," said Iizuka.

"By understanding the causes behind the continuous build-up of snow from the past to the present, we can clarify what will happen going forward and why the ice has grown."

Since the samples arrived in November, his team has worked in freezing storage facilities to log the density, alignment of snow grains, and the structure of ice layers.

In December, when AFP visited, the scientists were kitted out like polar explorers to cut and shave ice samples in the comparatively balmy minus 20C of their lab.

The samples can tell stories about weather conditions going back decades, or even centuries.

A layer of clear ice indicates a warm period when the glacier melted and then refroze, while a low-density layer suggests packed snow, rather than ice, which can help estimate precipitation.

Brittle samples with cracks, meanwhile, indicate snowfall on half-melted layers that then refroze.

And other clues can reveal more information -- volcanic materials like sulfate ions can serve as time markers, while water isotopes can reveal temperatures.

The scientists hope that the samples contain material dating back 10,000 years or more, though much of the glacier melted during a warm spell around 6,000 years ago.

Ancient ice would help scientists answer questions such as "what kind of snow was falling in this region 10,000 years ago? What was in it?" Iizuka said.

"We can study how many and what kinds of fine particles were suspended in the atmosphere during that ice age," he added.

"I really hope there is ancient ice."

For now, the work proceeds slowly and carefully, with team members like graduate student Sora Yaginuma carefully slicing samples apart.

"An ice core is an extremely valuable sample and unique," said Yaginuma.

"From that single ice core, we perform a variety of analyses, both chemical and physical."

The team hopes to publish its first findings next year and will be doing "lots of trial-and-error" work to reconstruct past climate conditions, Iizuka said.

The analysis in Hokkaido will uncover only some of what the ice has to share, and with the other samples preserved in Antarctica, there will be opportunities for more research.

For example, he said, scientists could look for clues about how mining in the region historically affected the area's air quality, temperature and precipitation.

"We can learn how the Earth's environment has changed in response to human activities," Iizuka said.

With so many secrets yet to learn, the work is "extremely exciting," he added.

Fans of Jane Austen celebrated the acclaimed author's 250th birthday on Tuesday with a church service in her home village, festive visits to her house — and a virtual party for those paying tribute from afar.

Thousands of enthusiasts around the world have already taken part in a yearlong celebration of one of English literature’s greats, who penned “Pride and Prejudice," “Sense and Sensibility” and other beloved novels.

On Tuesday — to mark 250 years since she was born on Dec. 16, 1775 — Jane Austen’s House, in the southern English village of Chawton, hosted talks, tours and performances for dozens of visitors, with celebrations concluding with an online party for fans from all over the world.

“Regency dress strongly encouraged,” organizers said, adding that more than 500 people had signed up for the Zoom party.

The cottage, now a museum with Austen artifacts, was where the author lived for the last years of her life and where she wrote all six of her novels.

A church service featuring music and readings is held in Steventon, the rural village where she was born.

Fans, who call themselves “Janeites," have marked the anniversary year with Regency balls and festivals staged in the UK, US and beyond.

At the weekend, the city of Bath, where Austen lived for five years, hosted the Yuletide Jane Austen Birthday Ball, the finale of many grand costumed events held there this year.
