NYU Abu Dhabi researchers find mysterious new set of waves in Sun

Researchers from NYU Abu Dhabi’s (NYUAD) Centre for Space Science have discovered a new set of waves in the Sun that, unexpectedly, appear to travel much faster than predicted by theory.

In the study, ‘Discovery of high-frequency-retrograde vorticity waves in the Sun’, published in the journal Nature Astronomy, the researchers, led by Research Associate Chris S. Hanson, detailed how they analysed 25 years of space and ground-based data to detect these waves. The high-frequency retrograde (HFR) waves, which move in the opposite direction of the Sun’s rotation, appear as a pattern of vortices (swirling motions) on the surface of the Sun and move at three times the speed established by current theory.

The interior of the Sun and stars cannot be imaged by conventional astronomy (e.g. optical, x-ray etc.), and scientists rely on interpreting the surface signatures of a variety of waves to image the interiors. These new HFR waves may yet be an important puzzle piece in our understanding of stars.

Complex interactions between other well known waves and magnetism, gravity or convection could drive the HFR waves at this speed. “If the HFR waves could be attributed to any of these three processes, then the finding would have answered some open questions we still have about the Sun,” said Hanson. “However, these new waves don’t appear to be a result of these processes, and that’s exciting because it leads to a whole new set of questions.”

This research was conducted within NYUAD’s Centre for Space Science in collaboration with the Tata Institute of Fundamental Research (TIFR) and New York University, using NYUAD and TIFR’s computational resources. By studying the Sun’s interior dynamics – through the use of waves – scientists can better appreciate the Sun’s potential impact on the Earth and other planets in our solar system.

“The very existence of HFR modes and their origin is a true mystery and may allude to exciting physics at play,” said Shravan Hanasoge, a co-author of the paper. “It has the potential to shed insight on the otherwise unobservable interior of the Sun.”

Rio Ferdinand house for sale: Man Utd legend puts Kent mansion on market after Dubai move

Rio Ferdinand may be done with UK living, for now.

The former Manchester United star, 47, has listed his seven-bedroom Kent mansion for £10.5 million (Dh52 million), hinting his move to Dubai is permanent.

Set in the exclusive Farnborough Park estate, the 12,500 sq ft home features landscaped grounds, a private gym, grand reception spaces, and a luxury master suite with dual dressing rooms. He bought it in 2008 for around £2.7 million, meaning a potential £8 million profit, though tax could apply depending on residency status.

Ferdinand moved to Dubai last year with his wife Kate and their children. They are now living in a luxury villa in Al Barari.

He has been candid about the move, citing more family time, an improved lifestyle, and the appeal of a fresh start. “The lifestyle, safety and weather, it just works for us,” Ferdinand said in the report.

He’s not alone. Vincent Kompany is also reportedly selling his UK home, as more football names rethink where they’re based.

A new limited-edition collection of gold and silver commemorative coins has been launched in the UAE, celebrating national unity while supporting community development efforts across Dubai.

The initiative, led by Emirates Minting Factory in collaboration with Dubai Gold District, is inspired by the ‘Proud of UAE’ campaign and is available exclusively within the district. The collection offers collectors and investors a chance to collect a symbolic piece tied to a defining moment in the nation’s recent history.

Beyond its collectable value, the project carries a philanthropic dimension. Proceeds from the sale of the coins will go to Ferjan Dubai, a social enterprise focused on strengthening community life and enhancing social well-being across neighbourhoods.

Officials say the initiative reflects a broader message of unity and resilience. Essa Al Falasi, Chairman of Emirates Minting Factory, described the coins as symbols of “gratitude and solidarity,” noting that the project aims to combine tangible value with meaningful impact. As a UAE-founded company, he added, the factory sought to contribute in a way that resonates with both national pride and social responsibility.

Each coin is crafted with investment-grade 1 oz gold and silver, reflecting the UAE’s heritage through detailed design and high-quality minting. The collection is positioned not only as a commemorative keepsake but also as a long-term asset for collectors.

The launch comes amid a growing trend of purpose-driven luxury products in the region, blending investment appeal with social impact.

The General Authority of Islamic Affairs, Endowments and Zakat has announced that the upcoming Friday sermon in the UAE will urge worshippers to uphold national loyalty and report activities that may threaten security, while warning against actions that undermine national unity.

Delivered under the title “Whoever betrays our nation is not one of us”, the sermon will emphasise that honesty and trust are core Islamic values, describing betrayal as a grave sin.

Worshippers, particularly youth, will be urged to remain vigilant and not be misled by narratives. The message will stress unity, adherence to authentic teachings, and respect for the country’s laws and leadership.

It will also highlight the role of security services in safeguarding stability and urge individuals to report suspicious behaviour through official channels, noting that concealing wrongdoing is itself a serious offence.

The sermon will pay tribute to the UAE Armed Forces ahead of their unification anniversary on May 6, and conclude with prayers for the nation’s safety, leadership and continued prosperity.
