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.”
Travellers arriving at Dubai International Airport are being greeted with a unique souvenir, a special stamp on their passports celebrating the Dubai World Cup 2026.
The initiative, launched by the General Directorate of Identity and Foreigners Affairs (GDRFA), marks the 30th edition (Pearl Jubilee) of one of the world’s most prestigious horse racing events.
A grand sporting celebration
The iconic Dubai World Cup will take place on Saturday, March 28 at Meydan Racecourse, drawing global attention from racing fans and elite stables.
This year’s event promises high-stakes action:
- 100 horses from top international stables
- Nine races across the evening
- Total prize pool of $30.5 million
Spotlight on the main race
The highlight of the night is the $12 million Dubai World Cup race, sponsored by Emirates Airline.
Run over 2,000 metres on dirt, the Group 1 race will feature some of the world’s top thoroughbreds, including:
- “Hit Show” – last year’s winner
- “Forever Young” – UAE Derby and Saudi Cup champion
- “Imperial Emperor”
- “Meidan” – Super Saturday winner
A memorable arrival experience
The commemorative passport stamp adds a celebratory touch for visitors landing in Dubai, tying their arrival to one of the city’s biggest sporting spectacles.
With excitement building ahead of race day, Dubai is once again showcasing its ability to blend world-class sport with unique visitor experiences.
