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.”
Emirates Dubai 7s is returning to The Sevens Stadium from November 27 to 29, with tickets now on sale for the three-day sports and entertainment festival.
The 2026 edition will bring together international rugby, amateur sports, live music and family entertainment, with organisers promising a bigger programme than previous years.
The festival attracted more than 88,000 visitors in 2025 and will again take place during the final weekend of the Dubai Fitness Challenge.
Ticket prices
Ticket prices for General Admission and Hospitality have stayed the same for a third consecutive year.
Three-day General Admission tickets cost Dh595 per person, while the three-day Family Pass is Dh1,136 for two adults and two children.
Other ticket options
- Group pass: Dh446 per person for four or more adults
- Saturday or Sunday: Dh455
- Friday: Dh75
- Under 15s: Free
- People of Determination + carer: Dh375
Tickets can be purchased through the Emirates Dubai 7s website and app.
Bigger family attractions
Family entertainment will get a major boost this year as the UAE celebrates the Year of the Family.
The festival will feature its biggest-ever Kids’ Zone, including the UAE’s largest inflatable kids’ zone, along with a Ferris wheel and zipline. More attractions are expected to be announced ahead of the event.
Six sports and top rugby action
Alongside elite rugby, visitors can watch or take part in competitions across six sports — rugby, netball, cricket, WODON3 fitness, Rebound padel and Gaelic Football.
Gaelic Football will join the festival for the first time in 2026.
The Sevens Stadium will also host the opening round of the HSBC SVNS Series 2027, bringing the world’s leading rugby sevens players to Dubai.
The WODON3 Elite final will take place on Pitch 1 between HSBC SVNS matches, with competitors potentially performing in front of crowds of up to 20,000.
Music all weekend
Live entertainment will run throughout the festival, with local and international artists performing across three days.
Last year’s line-up included Tinie Tempah, Sean Paul and Fisher, while the 2026 headline acts will be announced later.
For a premium experience, The Sunroom returns with all-inclusive food and drinks, shaded seating, prime sporting views and dedicated access. Packages start from Dh1,925 per person.
With sport, music and family attractions packed into one weekend, Emirates Dubai 7s is gearing up for another big Dubai event.
