Astronomers are tracking a newly spotted comet hailing from parts unknown, only the third time such an interstellar object has been observed visiting our solar system.

According to US space agency NASA, the interloper - named 3I/ATLAS - was first spotted on Tuesday by an Asteroid Terrestrial-impact Last Alert System, or ATLAS, telescope located in Rio Hurtado, Chile. Astronomers said its unusual trajectory indicated it had ventured from beyond our solar system.

Journeying at a speed of around 37 miles (60 km) per second from the direction of the center of the Milky Way galaxy, 3I/ATLAS is presently located about 420 million miles (670 million kilometers) from Earth.

"Beyond that we do not know very much, and there are many efforts underway to observe this object with larger telescopes to determine composition," University of Hawaii astronomer Larry Denneau, co-principal investigator for ATLAS, said on Thursday.

The only other such interstellar visitors previously observed by astronomers were objects called 1I/'Oumuamua (pronounced oh-MOO-uh-MOO-uh), detected in 2017, and 2I/Borisov, discovered in 2019.

"The comet has some similarities to 2I/Borisov in that it appears to be an icy comet, but it is much larger, possibly 10 km (6.2 miles) in diameter," Denneau said.

"It currently has a faint coma," Denneau added, referring to the cloud of gas and dust surrounding a comet's nucleus, "but the coma and tail may increase dramatically as the object comes closer to the sun. Its closest approach to the sun will be later this year, when it will come inside the orbit of Mars. We don't know what will happen, so that's exciting."

Astronomers said the comet poses no threat to Earth and will never come closer than 150 million miles (240 million km) away, equivalent to more than 1-1/2 times the distance between Earth and the sun. It is currently located about 416 million miles (670 million km) from the sun and will reach its closest approach to the sun around October 30, when it will be about 130 million miles (210 million km) away from our star.

The ATLAS network is a NASA-funded telescope survey built and operated by the University of Hawaii, with five telescopes around the world that scan the night sky continuously to look for objects that could threaten Earth.

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.

Italian paleontologists have uncovered thousands of dinosaur footprints on a near-vertical rock face more than 2,000 meters above sea level in the Stelvio National Park, a discovery they say is among the world's richest sites for the Triassic period.

The tracks, some up to 40 cm wide and showing claw marks, stretch for about five kilometers in the high-altitude glacial Valle di Fraele near Bormio, one of the venues for the 2026 Winter Olympics in the northern region of Lombardy.

"This is one of the largest and oldest footprint sites in Italy, and among the most spectacular I've seen in 35 years," said Cristiano Dal Sasso, paleontologist at Milan's Natural History Museum in a press conference on Tuesday at the headquarters of the Lombardy Region.

Experts believe the prints were left by herds of long-necked herbivores, likely plateosaurs, more than 200 million years ago when the area was a warm lagoon, ideal for dinosaurs to roam along beaches, leaving tracks in the mud near the water.

"The footprints were impressed when the sediments were still soft, on the wide tidal flats that surrounded the Tethys Ocean," said Fabio Massimo Petti, ichnologist at MUSE museum of Trento, attending the same conference.

"The muds, now turned to rock, have allowed the preservation of remarkable anatomical details of the feet, such as impressions of the toes and even the claws," Petti added.

As the African plate gradually moved north, closing and drying up the Tethys Ocean, sedimentary rocks that formed the seabed were folded, creating the Alps.

The fossilized dinosaur footprints shifted from a horizontal position to the vertical one on a mountain slope spotted by a wildlife photographer in September while chasing deer and bearded vultures, experts said.

"The natural sciences deliver to the Milan-Cortina 2026 Games an unexpected and precious gift from remote eras," Giovanni Malagò, President of the Milano Cortina 2026 Organizing Committee told journalists.

The area cannot be reached by trails, so drones and remote sensing technologies will have to be used to study it.

Another Home in British Village Torn Down Due to Seaside Erosion

Another Home in British Village Torn Down Due to Seaside Erosion

Demolition work has begun on a second clifftop home in a picturesque seaside spot, just weeks after another property was knocked down in the village.

Bulldozers have started tearing down The Chantry, in Thorpeness on the Suffolk coast because of its proximity to the crumbling cliff edge, according to ITV News.

The four-bedroom home on North End Avenue was put up for auction in September, selling for £200,000, according to the agents' website.

But East Suffolk Council said demolition had to begin after “critical safety levels” were reached.

At the end of October, neighbor Jean Flick, 88, saw her clifftop home in Thorpeness demolished after what the council described as “significant erosion.”

Evelyn Rumsby, who has lived in the village since 1977, described the latest demolition as “heartbreaking.”

“I don’t think unless you live here, you can’t experience anything like it... the noise of these lovely homes going,” she said, holding back tears.

“The erosion has been extreme over the last months, really extreme, and our only hope now is the shingle might come back if the winds change and we don’t have the intensity of these high winds that we’ve had over the last few months.”

“I do have fears,” she said. “We have to acknowledge that if it [erosion] moved in and this road went, there would be no access to our home site. It’s the access to the properties that is a big consideration.”

A spokesperson for East Suffolk Council said: “We have been working closely with affected property owners following significant recent erosion and sadly, critical safety levels have now been reached for another property on North End Avenue.”

He said demolition is in progress and we will continue to support the owners and their contractors to ensure the building can be taken down safely.

“This is a distressing situation, and we would request that people respect the owner’s privacy at this difficult time,” the spokesperson said.

“It is impossible to accurately predict when further losses may occur as erosion is not linear. Therefore, we are regularly monitoring the area and engaging with property owners on an ongoing basis.”
