Cruise Saudi, a Public Investment Fund company, has announced that AROYA Cruises’ inaugural ship, AROYA, arrived in Jeddah on Saturday in preparation for establishing Jeddah Islamic Port as the primary departure point for its tourist cruises in the Red Sea.
The occasion was celebrated with a traditional plaque and key ceremony attended by Chief Executive Officer of Cruise Saudi Lars Clasen, President of AROYA Cruises Dr. Jörg Rudolph, Captain of AROYA Jan Gelinder, and Chief Destination Experiences Officer Barbara Buczek.
According to a statement, after months of dry-docking and innovative design work in Bremerhaven and Rotterdam—where 95% of the ship’s spaces were completely transformed to reflect Arabian heritage—AROYA is now set to provide “an exceptional cruising experience with a fully reimagined interior.”
The ship, the statement added, is outfitted with a wide range of world-class facilities, including a souq-inspired shopping district—the largest retail area ever built on a cruise ship—luxurious spa facilities, a wellness center, 29 restaurants, lounges, and cafés, 20 entertainment venues, and one of the largest children’s play areas at sea.
Cruise Saudi confirmed that the infrastructure and logistics services at Jeddah Islamic Port are fully prepared to accommodate large cruise ships, following a comprehensive modernization of its facilities. The port’s historical significance as the primary gateway to the Two Holy Mosques in Makkah and Madinah further enhances its status as a global tourist hub.
“The arrival of AROYA marks the beginning of a new chapter for Cruise Saudi and tourism in Saudi overall, in line with Saudi’s Vision 2030,” said Chief Executive Officer of Cruise Saudi Lars Clasen.

“Cruise Saudi was only launched in 2021, and witnessing the arrival of our first owned ship just three years later is a huge milestone. We are so grateful to the whole Cruise Saudi team for their hard work and dedication and are excited to be offering something truly unique to local, regional, and international guests with the first-ever Arabian cruise line,” he added.
AROYA’s maiden voyage will depart Jeddah on December 16, taking passengers on a three-night journey across the Red Sea.

Scientists have observed the largest-known rotating structure in the cosmos - a gargantuan thread-like assemblage of hundreds of galaxies, gas and dark matter that makes up a filament in the macrostructure of the universe called the cosmic web.

The filament, located about 140 million light-years from Earth, was observed by scientists primarily using the MeerKAT radio telescope located in South Africa, an array of 64 interlinked satellite dishes.

The rotating filament is astonishingly large, measuring about 50 million light-years long and 117,000 light-years wide. A light-year is the distance light travels in a year, 5.9 trillion miles (9.5 trillion km). By way of comparison, our Milky Way galaxy, which itself is part of a filament in the cosmic web, measures roughly 100,000 light-years in diameter.

"We believe that the universe on very large scales is made of a network-like distribution of galaxies, gas and dark matter," said University of Cambridge astrophysicist Madalina Tudorache, co-lead author of the study published this month in the journal Monthly Notices of the Royal Astronomical Society.

"This network is called the cosmic web, and it is formed of clusters, which are very dense clumps of matter, often formed of many groups of galaxies; voids - which are empty or almost empty regions of space; and filaments, which are strand-like structures which connect the very dense regions and border the voids," Tudorache said.

The rotating filament described in the new study is populated by nearly 300 galaxies of various sizes as well as gas and dark matter, the mysterious invisible stuff estimated to make up 27% of the cosmos.

Everything visible in the universe is made of ordinary matter - stars, planets, moons and all the stuff on Earth. It can be seen in wavelengths from infrared to visible light and gamma rays, but comprises only about 5% of the universe. Dark matter, on the other hand, does not absorb or reflect or emit light, but its presence is known through its gravitational effects on large scales.

The researchers determined that the filament is spinning by observing that the galaxies on either side of its central axis are moving through space in opposite directions, with the whole thing having a rotational velocity of about 246,000 miles (396,000 km) per hour.

"This is the largest individual spinning structure so far detected. Statistically, we believe there are other spinning structures, some of which could be larger. However, we have not been able to detect them directly with our current data and telescopes," said University of Oxford astrophysicist and study co-lead author Lyla Jung.

The researchers likened what they see in this filament to the amusement park attraction called a teacup ride.

"The teacup ride analogy explains the two levels of spinning motion that make this object unique," Jung said.

"First, each galaxy in the filament spins on its own. The gas and stars in each galaxy orbit around the galaxy center, like each teacup on the ride spins individually. Second, the entire cosmic filament also rotates. The filament is made of many galaxies, and this study demonstrates that the entire structure is rotating, like the teacup platform spins as a whole," Jung added.

In studying the cosmos, astrophysicists examine it at the smallest and largest scales. They look at tiny fundamental particles such as neutrinos. They look at objects such as comets, asteroids, moons, planets and stars that make up solar systems. They look at galaxies comprised of billions of stars and at clusters of galaxies. And then on the largest scales they look at filaments and other components of the cosmic web.

This study looks at the large end of things.

"This is a very exciting time to work in this field, as our capacity of discovering such structures is increasing with the advent of better radio and optical surveys. It will deepen our understanding of the universe," Tudorache said.

The National Center for Wildlife (NCW), in cooperation with the Royal Commission for AlUla, has released 37 wildlife species into Hegra Reserve as part of ongoing breeding and reintroduction programs aimed at restoring natural habitats, enriching biodiversity, supporting ecological balance, and promoting environmental tourism.

The release included six mountain ibex, 20 sand gazelles (reem), six idmi gazelles, and five ostriches, SPA reported.

This effort is part of NCW's continuing work to increase the numbers of threatened native species and expand their presence across suitable natural environments.

NCW CEO Dr. Mohammed Qurban stated that releasing these species into the reserve helps protect wildlife, safeguard ecosystems, and enrich biodiversity, strengthening the sustainability of the reserve and its role as a natural and cultural destination of national significance.

Qurban noted that this release is an extension of the center’s reintroduction efforts across reserves in the Kingdom, aimed at rehabilitating ecosystems, increasing biodiversity, and ensuring long-term sustainability. It aligns with the goals of Saudi Vision 2030, the Saudi Green Initiative, and the National Environment Strategy, while also adhering to global approaches to wildlife conservation.

An Australian firefighter was killed overnight after he was struck by a tree while trying to control a bushfire that had destroyed homes and burnt large swathes of bushland north of Sydney, authorities said on Monday.

Emergency crews rushed to bushland near the rural town of Bulahdelah, 200 km (124 miles) north of Sydney, after reports that a tree had fallen on a man. The 59-year-old suffered a cardiac arrest and died at the scene, officials said.

Prime Minister Anthony Albanese said the "terrible news is a somber reminder" of the dangers faced by emergency services personnel as they work to protect homes and families.

"We honor that bravery, every day," Albanese said in a statement.

A fast-moving fire over the weekend destroyed 16 homes in New South Wales state's Central Coast region, home to about 350,000 people and a commuter region just north of Sydney.

Resident Rouchelle Doust, from the hard-hit town of Koolewong, said she and her husband tried to save their home as flames advanced.

"He's up there in his bare feet trying to put it out, and he's trying and trying, and I'm screaming at him to come down," Doust told the Australian Broadcasting Corp.

"Everything's in it: his grandmother's stuff, his mother's stuff, all my stuff - everything, it's all gone, the whole lot."

Conditions eased overnight, allowing officials to downgrade fire danger alerts, though the weather bureau warned some inland towns in the state could hit more than 40 degrees Celsius (104 Fahrenheit) on Tuesday, raising fire dangers.

More than 50 bushfires were burning across New South Wales as of Monday.

On the island state of Tasmania, a 700-hectare (1,729 acres) blaze at Dolphin Sands, about 150 km (93 miles) northeast of the state capital of Hobart, destroyed 19 homes and damaged 40. The fire has been contained, but residents have been warned not to return as conditions remain dangerous, officials said.

Authorities have warned of a high-risk bushfire season during Australia's summer months from December to February, with increased chances of extreme heat across large parts of the country following several relatively quiet years.

In neighboring New Zealand, five helicopters and multiple crews were working to put out a fire near the country's oldest national park, a month after a wildfire burnt through 2,589 hectares (6,400 acres) of alpine bush there.

Police said they had closed a road near the state highway and advised motorists to avoid the area and expect delays after the blaze near Tongariro National Park, a popular hiking spot, spread to 110 hectares (272 acres) by Monday afternoon.
