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.”

UAE weather: Fair skies now, but hot and dusty conditions expected this weekend

Published

Spread the love

The National Centre of Meteorology has forecast generally fair weather across the UAE, with temperatures set to rise gradually before dusty and windy conditions develop towards the weekend.

General outlook

Conditions today are expected to remain mostly clear, with some cloud formation over eastern areas in the afternoon.

Temperatures will climb to:

  • 40°C to 45°C inland
  • Up to 39°C in coastal areas

Humidity could reach 85% along the coast, particularly during the night and early morning.

Winds will be light to moderate, occasionally fresh, with speeds reaching up to 35 km/h.

What to expect in the coming days

Similar weather patterns are expected to continue, with fair to partly cloudy skies across the country.

Winds will gradually shift direction, from north-westerly to south-easterly, and may strengthen at times, especially over the sea.

Weekend changes ahead

By Friday, temperatures are expected to dip slightly, but wind speeds could increase to around 40 km/h, making sea conditions rougher in the Arabian Gulf.

Heading into the weekend, dusty conditions and blowing sand are likely, particularly in exposed areas, as winds pick up further on Saturday and Sunday.

Sea conditions are forecast to be:

  • Moderate to rough in the Arabian Gulf
  • Slight to moderate in the Oman Sea

According to the National Centre of Meteorology (NCM), the conditions are linked to weak surface pressure systems combined with an upper-air high-pressure extension, contributing to rising temperatures and shifting wind patterns.

Spread the love

Life in Dubai continues to rank highly among residents, with 95% saying the city is their preferred place to live, according to the latest survey by the Community Development Authority.

The findings from the 2024–2025 Social Survey paint a picture of a city where happiness, safety and social connection remain key strengths, with overall life satisfaction reaching 8.72 out of 10.

A city that people are proud to call home

The survey shows that 96.4% of residents feel proud to live in Dubai, while the overall happiness score stands at 8.6, reflecting strong confidence in the quality of life across the emirate.

For expats, who make up a large share of the population, these figures highlight Dubai’s continued appeal as a place to live, work and build a future.

Family and community at the core

Strong family ties remain a defining feature, with the Family Bond Index exceeding 95%, while 84% of residents say they have someone to rely on in times of need.

Community engagement is also growing, with volunteering rates rising to over 13%, signalling a shift towards a more connected and socially active population.

Inclusive and connected living

The survey points to broad inclusivity across society:

  • Over 90% of People of Determination feel integrated
  • Similar levels report access to education and essential services
  • Nearly 99% of residents have internet access at home

Happiness among senior citizens also remains high, at nearly 87%, reflecting support across different age groups.

Shaping future policies

Officials say the results support the goals of the Dubai Social Agenda 2033 and the UAE’s Year of the Family, with a focus on strengthening social cohesion and wellbeing.

According to Hessa bint Essa Buhumaid, the survey serves as a key tool to guide policy, helping authorities respond to evolving community needs.

For those living in Dubai, the findings reinforce the emirate’s position as a city focused not just on growth, but on quality of life, stability and community wellbeing.

The UAE has marked a major national milestone, as leaders paid tribute to the country’s Armed Forces on the 50th anniversary of their unification, recognising their role in shaping the nation’s security and stability.

President His Highness Sheikh Mohamed bin Zayed Al Nahyan praised the “courageous men and women” who continue to safeguard the country, describing their dedication as a source of pride for everyone who calls the UAE home.

In a message shared on X, he highlighted the significance of the anniversary as a defining moment in the country’s history, reflecting on five decades of service and commitment.

Cornerstone of national unity

His Highness Sheikh Mohammed bin Rashid Al Maktoum, Vice President, Prime Minister and Ruler of Dubai, also marked the occasion, praising the Armed Forces for their decades of service, sacrifice and national duty.

In a speech commemorating the 50th anniversary of unification, he highlighted the role of the Armed Forces in strengthening the UAE’s global standing and protecting its achievements.

He described them as an “impregnable fortress” that has safeguarded the nation’s pride, dignity and stability, while honouring the dedication of those who have served since unification in 1976.

“We gather today to celebrate the golden jubilee of the decision to unify the UAE Armed Forces,” he said, reflecting on a milestone that continues to shape the country’s security and unity.

Sheikh Mansour bin Zayed Al Nahyan, Vice President and Deputy Prime Minister of the UAE and Chairman of the Presidential Court, described the Armed Forces as the nation’s “shield and backbone,” honouring generations who have contributed to protecting the country and its people.

Rulers of Sharjah, Ajman, Umm Al Quwain, Fujairah and Ras Al Khaimah also paid rich tributes to the Armed Forces.

Turning point

The unification of the Armed Forces in 1976 is widely seen as a turning point in the UAE’s development, helping strengthen national unity and build a coordinated defence system across the emirates.

For residents and expats alike, the milestone serves as a reminder of the stability and safety that underpin daily life in the UAE, factors that continue to support its growth as a global destination for living and working.

As the country looks ahead, leaders emphasised confidence in the future, building on a legacy of security, unity and resilience.
