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.”

The countdown to the 2026 FIFA World Cup has entered a new phase after FIFA officially released the final squad lists for the tournament, confirming a record 1,248 players across 48 national teams.

The expanded competition, which will be hosted by Canada, Mexico and the United States, will be the largest World Cup ever staged, featuring 104 matches and more participating nations than any previous edition.

Messi and Ronaldo set for historic milestone

Among the biggest storylines is the inclusion of football legends Lionel Messi and Cristiano Ronaldo, who are both set to make history by appearing in their sixth FIFA World Cup.

Mexico goalkeeper Guillermo Ochoa is also on course for a sixth World Cup campaign, placing him alongside the sport’s most enduring international stars.

New faces and new nations

While several football icons return, the tournament will also introduce a new generation of talent.

A total of 891 players are preparing for their first World Cup appearance, while 357 have previously been named in at least one tournament squad.

Four countries — Cabo Verde, Curaçao, Jordan and Uzbekistan — will make their World Cup debuts, reflecting the broader opportunities created by the tournament’s expansion to 48 teams.

Youngest and oldest players

Scotland goalkeeper Craig Gordon enters the tournament as the oldest player selected at 43 years old, while Mexico’s Gilberto Mora is the youngest squad member at just 17.

The final lists include 22 players under the age of 20 and seven players aged 40 or above when the tournament begins.

Truly global competition

The 1,248 selected players represent 449 clubs from 71 countries, highlighting football’s increasingly global footprint.

Some nations have leaned heavily on domestic talent. Qatar and Saudi Arabia selected 25 of their 26 players from local clubs, demonstrating the strength of their domestic leagues.

Others have taken the opposite approach. Cabo Verde, DR Congo, Côte d’Ivoire, Curaçao, Senegal and Uruguay have chosen squads made up entirely of players based overseas.

World Cup set for new era

With 48 teams, 104 matches and a record number of players, the 2026 FIFA World Cup promises to be the most expansive edition in the tournament’s history.

The final squad announcements now set the stage for a month-long celebration of football, where established superstars, emerging talents and debut nations will all compete on the sport’s biggest stage.

The UAE has officially declared Monday, June 15, 2026, a public holiday for both public and private sector employees to mark the Islamic New Year 1448.

The announcement was made by the Federal Authority for Government Human Resources and the Ministry of Human Resources and Emiratisation, confirming a paid day off for workers across the country.

Normal working hours will resume on Tuesday, June 16.

As the holiday falls on a Monday, most employees who enjoy a Saturday-Sunday weekend will benefit from a three-day break.

For government employees in Sharjah, the holiday will create an even longer weekend. With the emirate’s four-day workweek already providing Fridays, Saturdays and Sundays off, the additional Monday holiday means a four-day break.

The Islamic New Year, also known as the Hijri New Year, marks the beginning of a new year in the Islamic lunar calendar. It falls on the first day of Muharram, the opening month of the Hijri calendar, and is traditionally confirmed through official moon-sighting procedures.

The occasion is one of the UAE’s official public holidays and is observed by both government entities and private sector companies.

The announcement comes shortly after residents enjoyed the longest holiday period of the year during Eid Al Adha.

Earlier this month, government employees benefited from an extended nine-day break, while many private sector workers received up to six days off.

With June 15 now confirmed as a public holiday, UAE residents have another long weekend to look forward to before the summer holiday season gets underway.
