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.”

Indian chess star Praggnanandhaa Rameshbabu produced a brilliant final-round victory to win Norway Chess 2026, capping a dramatic finish to one of the year’s most prestigious tournaments.

Entering the final day half a point behind leader Wesley So, Praggnanandhaa knew only a win would give him a realistic chance of claiming the title. The 19-year-old delivered under pressure, defeating Vincent Keymer with the white pieces to secure the full three points and surge to first place.

The victory lifted Praggnanandhaa to 18 points, enough to overtake Wesley So and clinch the Norway Chess crown in Oslo.

So, who had led the standings heading into the final round, drew his classical game against Alireza Firouzja before winning the Armageddon tiebreak. However, the extra points were not enough to keep him ahead of the charging Indian grandmaster.

Firouzja completed a strong campaign to finish third overall.

Elsewhere, world No. 1 Magnus Carlsen signed off in style with a classical victory over reigning world champion Gukesh Dommaraju, delighting home fans with a final-round win.

Final Standings

  • Praggnanandhaa Rameshbabu – 18 points
  • Wesley So – 17 points
  • Alireza Firouzja – 15.5 points

Assaubayeva dominates women’s event

In the Norway Chess Women’s tournament, Bibisara Assaubayeva completed a dominant campaign to secure the title after having already wrapped up first place with a round to spare.

The final day featured three decisive classical games, eliminating the need for Armageddon tiebreaks.

Women’s world champion Ju Wenjun handed Assaubayeva her first classical defeat of the tournament, while Zhu Jiner defeated Humpy Koneru to secure second place overall. Anna Muzychuk also ended her campaign on a high note with a victory over Divya Deshmukh to finish third.

Norway Chess women’s final standings

  • Bibisara Assaubayeva – 16.5 points
  • Zhu Jiner – 16 points
  • Anna Muzychuk – 15 points

Praggnanandhaa’s triumph marks another major milestone in the young Indian grandmaster’s rapidly rising career and further strengthens India’s growing influence at the highest level of world chess.

Spread the love

Dubai’s Roads and Transport Authority (RTA) has confirmed the operational readiness of around 40 air-conditioned rest areas for delivery riders ahead of the peak summer season.

The facilities, located across key areas including Hessa Street, Al Khawaneej, Al Barsha, Al Satwa, Oud Metha, Al Karama and Arjan, are designed to help riders stay safe and comfortable while working during the hotter months.

According to the RTA, maintenance and preparation works have been completed at all locations, with site selection based on delivery demand and operational data gathered in coordination with delivery companies.

The initiative forms part of Dubai’s wider efforts to improve road safety, support rider wellbeing and enhance working conditions within the rapidly growing delivery sector.

Ahmed Mahboob, CEO of RTA’s Licensing Agency, said traffic safety remains a top priority and that the authority has developed an integrated framework to regulate and support the delivery industry.

Facilities inside rest area

Each rest area includes air-conditioned seating, drinking water facilities and mobile phone charging stations. Depending on the location, the facilities can accommodate around 10 riders at a time and also provide dedicated parking spaces for delivery motorcycles.

The structures have been specially designed to reduce heat exposure and provide thermal insulation, allowing riders to take a break from the sun while remaining close to their delivery routes.

The move comes as Dubai continues to implement measures aimed at improving safety, comfort and quality of life for delivery riders, particularly during the summer months when temperatures can soar.
