Scientists unveil image of supermassive black hole at Milky Way’s center

Scientists on Thursday provided the first look at the monster lurking at the center of our Milky Way galaxy, unveiling an image of a supermassive black hole that devours any matter wandering within its gargantuan gravitational pull.
The black hole — called Sagittarius A*, or SgrA* — is only the second one ever to be imaged. The feat was accomplished by the same Event Horizon Telescope (EHT) international collaboration that in 2019 unveiled the first-ever photo of a black hole — that one residing at the heart of a different galaxy.

Sagittarius A* possesses 4 million times the mass of our sun and is located about 26,000 light-years — the distance light travels in a year, 5.9 trillion miles (9.5 trillion km) — from Earth.
Black holes are extraordinarily dense objects with gravity so strong that not even light can escape, making viewing them quite challenging. A black hole’s event horizon is the point of no return beyond which anything — stars, planets, gas, dust and all forms of electromagnetic radiation — gets dragged into oblivion.
Project scientists have looked for a ring of light — super-heated disrupted matter and radiation circling at tremendous speed at the edge of the event horizon — around a region of darkness representing the actual black hole. This is known as the black hole’s shadow or silhouette.
The Milky Way is a spiral galaxy that contains at least 100 billion stars. Viewed from above or below it resembles a spinning pinwheel, with our sun situated on one of the spiral arms and Sagittarius A* located at the center.
The image released in 2019 of the supermassive black hole in a galaxy called Messier 87, or M87, showed a glowing ring of red, yellow, and white surrounding a dark center. The M87 black hole is far more distant and massive than Sagittarius A*, situated about 54 million light-years from Earth with a mass 6.5 billion times that of our sun.
The researchers said that Sagittarius A*, despite being much closer to our solar system than M87, was harder to image.
The diameter of Sagittarius A* is about 17 times that of the sun, meaning it would sit within the innermost planet Mercury’s solar orbit. In contrast, M87’s diameter would encompass the entirely of our solar system.
“Sagittarius A* is over a thousand times less massive than the black hole at M87, but since it is in our own galaxy it is much closer and should appear just slightly larger on the sky,” said radio astronomer Lindy Blackburn, an EHT data scientist at the Harvard-Smithsonian Center for Astrophysics.
“However, the smaller physical size of Sgr A* also means that everything changes about a thousand times faster for Sgr A* than M87. We must also peer through the messy disk of our own galaxy to view Sgr A*, which blurs and distorts the image,” Blackburn added.
The Event Horizon Telescope is a global network of observatories working collectively to observe radio sources associated with black holes. The project was begun in 2012 to try to directly observe the immediate environment of a black hole.
There are different categories of black holes. The smallest are so-called stellar-mass black holes formed by the collapse of massive individual stars at the ends of their life cycles. There also are intermediate-mass black holes, a step up in mass. And finally there are the supermassive black holes that inhabit the center of most galaxies. These are thought to arise relatively soon after their galaxies are formed, devouring enormous amounts of material to achieve colossal size.
Thursday’s announcement was made in simultaneous news conferences in the United States, Germany, China, Mexico, Chile,
Japan, and Taiwan.

Arabian Saluki Beauty Contest at ADIHEX 2024: A celebration of ancestral elegance

The Abu Dhabi International Hunting and Equestrian Exhibition (ADIHEX) announce the return of the prestigious Arabian Saluki Beauty Contest, a unique initiative aimed at highlighting the significance of purebred hunting dogs and fostering a connection between the new generation and their rich ancestral heritage.
Under the esteemed patronage of H.H. Sheikh Hamdan bin Zayed Al Nahyan, Ruler’s Representative in Al Dhafra Region and Chairman of the Emirates Falconers’ Club (EFC), this iconic event is scheduled from 31st August to 8th September, 2024, at ADNEC Centre Abu Dhabi, celebrating the blending of deep Emirati cultural traditions with cutting-edge innovation and technology across 11 diverse sectors.
A highlight of this year’s event is the Arabian Saluki Beauty Contest. One of the world’s oldest and most revered dog breeds, the Arabian Saluki stands as a symbol of wild hunting and desert traditions in the Middle East. Known for its grace, speed, and intelligence, this distinctive breed has been a faithful companion to the Bedouin people for over 5,000 years, serving as both a hunter and guardian. The Saluki’s agility and loyalty have made it an integral part of hunting and racing traditions, especially within the Arabian Peninsula.
The Arabian Saluki Centre was established in Abu Dhabi in 2001 alongside the Emirates Falconers’ Club, marking the first facility of its kind in the Arabian Gulf region and the Middle East, to revive the tradition of desert hunting using Saluki dogs, a cherished aspect of desert heritage.
ADIHEX was the first cultural event in the Arab region to honour the bond between Man and his loyal companion, which has been by our side for thousands of years. The Arabian Saluki Beauty Contest is a unique initiative designed to promote interest in purebred hunting dogs and to strengthen the new generation’s connection to their ancestral heritage and traditions and to serve as a testament to this unique bond.
With its origin steeped in history, this fascinating dog’s name is believed to be derived from the city of Saluk in Yemen or the Bani Saluk tribe. Renowned for its endurance and elegance, the Saluki can reach speeds up to 75 kilometres per hour, maintaining this pace over distances up to almost five kilometres. The breed is cherished for its unique physical characteristics, including a slender body, deep chest, long legs, and two distinct coat types: ‘Al Hoss’ (smooth) and ‘Aryash’ (feathery).
The Arabian Saluki Beauty Contest, held during ADIHEX, is more than a beauty pageant. It celebrates the essence of the Saluki by focusing on the dog’s personality, skills, reflexes, and sensory response. Unlike typical dog competitions, this contest evaluates the Saluki’s breed characteristics, behaviour, overall appearance, structure, hunting skills, and psychological traits. Judging criteria include the dog’s gait, head, eyes, mouth, ears, coat, colour, and general impression.
The Arabian Saluki Beauty Contest is an integral part of ADIHEX’s mission to preserve and promote the cultural heritage of the UAE and the wider Arab world. This contest not only showcases the beauty and abilities of the Saluki but also plays a vital role in raising awareness about the importance of preserving traditional hunting practices and the Saluki’s role in them.
This year’s competition will feature four categories: ‘Smooth (Hoss) Males,’ ‘Feathery (Aryash) Males,’ ‘Smooth (Hoss) Females,’ and ‘Feathery (Aryash) Females.’ The event is scheduled to take place during ADIHEX 2024, and, per the rules, participants must ensure their dogs are healthy, microchipped, and vaccinated.
The Saluki’s enduring legacy is celebrated through this competition, which draws participants and spectators from across the region and beyond. It provides a platform for Saluki enthusiasts to connect, share their passion, and celebrate a breed that has remained virtually unchanged for millennia, reflecting the diverse hunting landscapes and traditions of the Middle East.
Aside from the alluring Arabian Saluki Beauty Contest, as the largest edition of ADIHEX to date, the 21st edition will showcase thousands of brands across 11 diverse sectors, offering a dynamic platform for new business opportunities and captivating audiences of all ages. This exhibition celebrates the thrill of an adventurous outdoor lifestyle, allowing visitors to explore falconry, hunting, equestrian sports, veterinary products, fishing and marine sports, environmental preservation, cultural heritage, arts and crafts, and the latest in technology and innovation across all the represented sectors.
