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.”

New Dh750m Sharjah-Dubai traffic solution plan: What motorists need to know

Published

Spread the love

For years, motorists travelling between Sharjah and Dubai have faced some of the UAE’s longest daily traffic delays. Now, a major infrastructure programme announced by Sharjah is aiming to change that.

His Highness Sheikh Dr Sultan bin Mohammed Al Qasimi, Supreme Council Member and Ruler of Sharjah, has unveiled a package of road projects worth Dh750 million that will introduce new routes into Dubai, expand key traffic corridors and create a direct underground link beneath one of Sharjah’s busiest intersections.

The flagship project is a tunnel that will pass underneath Al Taawun Roundabout, creating a dedicated route for vehicles heading towards Dubai through Al Nahda Bridge. The tunnel is expected to remove a significant volume of through-traffic from surface roads, helping ease congestion in an area that regularly experiences heavy peak-hour delays.

New corridor

Alongside the tunnel, Sharjah is building Noor Road, a new corridor that will connect Al Orooba Street directly with Dubai. Though the competition date is yet to be announced, Sheikh Dr Sultan said Noor Road is scheduled to open before the end of 2026 and is expected to provide motorists with an additional alternative to existing entry points between the two emirates.

The projects form part of a broader strategy to improve traffic across Sharjah’s eastern and central districts while strengthening links with Dubai. Road upgrades will focus on improving access between residential communities, commercial centres and major highways, creating a more efficient network for both daily commuters and businesses.

Transport challenges

Traffic between Sharjah and Dubai remains one of the UAE’s biggest transport challenges, with thousands of residents crossing emirate borders every day for work and education. Officials believe the new projects will help distribute traffic more evenly across the network, reduce pressure on existing bottlenecks and improve journey reliability.

Authorities say the investment is not solely about reducing congestion. The developments are also intended to support future urban growth and improve connectivity.

While construction timelines for some elements are still being finalised, Noor Road is expected to be operational by the end of next year, marking one of the first major milestones in the programme.

Learning to drive in Dubai? RTA approves new training institutes across city

Spread the love

Getting driving lessons in Dubai could soon become much more convenient for residents living in some of the city’s fast-growing neighbourhoods.

Dubai’s Roads and Transport Authority (RTA) has approved an expansion of areas where new driver training institutes and branches can be established, making it easier for residents to access driving lessons closer to home.

The initiative is designed to support Dubai’s continued urban growth while improving access to essential licensing and driver education services across the emirate.

New areas

The newly approved locations include:

  • Wadi Al Safa
  • Jebel Ali
  • Mushrif
  • Al Maktoum City
  • Madinat Hind

With these communities continuing to attract new residents, the move is expected to reduce travel times for learner drivers while improving access to training facilities.

Opportunity for investors

The expansion isn’t just good news for residents. It also opens the door for accredited driving institutes looking to grow their footprint and for new investors interested in entering Dubai’s driver training sector.

RTA has invited eligible operators and investors to apply for licences to establish new branches in line with the authority’s regulations and service standards.

Ahmed Mahboob, CEO of RTA’s Licensing Agency, said this decision will bring services closer to residents in emerging communities and support Dubai’s long-term development plans.

He noted that easier access to driver training services will help reduce the need for long commutes while contributing to safer roads and better mobility across the city.

He also highlighted RTA’s commitment to supporting investors through a streamlined application process that aligns with existing laws and policies.

Beyond convenience, the expansion is expected to strengthen driver education standards across Dubai by increasing access to quality training and promoting greater traffic awareness among motorists.

As Dubai continues to grow, the authority says expanding driver training infrastructure will play an important role in preparing safer and more confident drivers for the roads.

UAE waives overstay fines: Stranded travellers to get 30-day visa grace period

Published

Spread the love

The UAE has introduced a 30-day grace period for individuals who were previously unable to leave the country due to exceptional regional circumstances, giving them time to regularise their status or depart without incurring penalties.

According to the Federal Authority for Identity, Citizenship, Customs and Port Security (ICP), the grace period runs from June 10 to July 9, 2026, and applies to people who had benefited from an earlier exemption on overstay fines.

The move comes as travel conditions across the region have largely stabilised, allowing affected individuals to make the necessary arrangements to either remain in the UAE legally or complete their departure procedures.

Authorities said the measure is designed to support compliance with immigration regulations while providing a practical window for people to update their residency, employment or visa status.

The ICP noted that its earlier decision to waive overstay fines was introduced as a humanitarian response to exceptional circumstances that disrupted travel plans for many residents and visitors.

With regional conditions improving, the authority said the reasons behind the temporary exemption no longer apply, making it possible for normal procedures to resume.

Individuals who wish to stay in the UAE can use the grace period to adjust their residency or employment status through the usual channels. Those planning to leave the country can do so without any additional preliminary requirements, provided they complete their departure during the specified period.

The authority also encouraged affected individuals to monitor official communication channels for the latest updates and guidance.

Earlier this year, the UAE exempted visa holders, exit permit holders and residents with cancelled visas from overstay fines after widespread travel disruptions, including flight suspensions and airspace closures, prevented many from leaving the country. The exemption was introduced to ease the financial burden on those impacted by circumstances beyond their control.
