NYU Abu Dhabi researchers find mysterious new set of waves in Sun

Published

on

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.”

UAE announces Eid Al Fitr holidays for the public sector

Published

on

The Federal Authority for Government Human Resources (FAHR) has announced that the Eid Al Fitr holiday for the federal government sector will be observed from 1st to 3rd Shawwal 1446 AH, with work resuming on 4th Shawwal.

In an announcement posted on social media by uae_barq: “The Federal Authority for Government Human Resources (FAHR) today issued a circular announcing that the Eid Al Fitr holiday for the federal government sector will be observed from 1st to 3rd Shawwal 1446 AH, with official work resuming on 4th Shawwal.”

If Ramadan lasts 30 days, the 30th of Ramadan will be designated as an additional public holiday, extending the Eid break.

On this occasion, the Authority extended its congratulations to the UAE government, its people, residents, and the Arab and Islamic nations, wishing them continued prosperity and well-being.

The exact duration of Ramadan, which determines the Eid Al Fitr holiday, will be confirmed only after the moon-sighting committee convenes. This is expected to take place on Friday, March 28, stay tuned for updates.

UAE Marks International Women’s Day with game-changing empowerment moves

Published

on

The UAE is marking International Women’s Day today (March 8) with a powerful statement – women’s empowerment is moving full speed ahead.

From smashing global gender rankings to securing top government roles, Emirati women are taking centre stage in the country’s unstoppable progress.

Breaking Barriers and Making History

The UAE has skyrocketed to 7th place globally in the 2024 Gender Inequality Index (GII), issued by the United Nations Development Programme (UNDP), securing its spot as the top performer in the region.

And that’s not all – the government is putting women in key leadership positions, with the recent appointment of Sana bint Mohammed Suhail as Minister of Family under the newly established Ministry of Family.

Women’s health is also getting a major boost with the launch of the National Policy for the Promotion of Women’s Health, ensuring top-quality healthcare for women across all stages of life.

Boardrooms, Business and Beyond

In a game-changing move for women in business, the Ministry of Economy now requires private joint-stock companies to have at least one woman on their board of directors – a huge win for gender equality in corporate leadership!

Meanwhile, the General Women’s Union has rolled out the Women’s Economic Empowerment Programme, giving young female entrepreneurs and business owners the tools they need to thrive in the UAE’s booming economy.

Women at the Forefront of Global Change

The UAE isn’t just focusing on local success – it’s shaping the global conversation on women’s rights.

Last year, the country co-authored a historic UN resolution with the UK, ensuring equal access to education for girls worldwide. It’s also one of the biggest donors to UN Women, contributing a whopping $46 million to support women’s initiatives across the globe.

When it comes to peace and security, the UAE is leading the charge. During its 2022-2023 tenure on the UN Security Council, the country pushed for greater female representation in peacekeeping and conflict resolution.

Plus, the Sheikha Fatima bint Mubarak Initiative for Women, Peace, and Security has already trained hundreds of female cadets from the Arab region, Africa, and Asia, ensuring women have a powerful role in global security.

A Future Powered by Women

Since its founding, the UAE has made huge strides in gender equality – from equal pay laws to women holding half of the seats in the Federal National Council. And with its unstoppable drive, the future is looking brighter than ever for Emirati women.

ICC Championship trophy final: What if weather plays spoilsport for New Zealand, India match?

Published

on

With rain disrupting multiple matches in the ICC Champions Trophy 2025, all eyes are on the weather as India and New Zealand prepare for the March 9 final in Dubai. While Pakistan saw three washouts, Dubai has remained dry so far—but could that change on the big day?

What’s the weather forecast?

According to the National Center of Meteorology (NCM), there will be a change in the weather, as temperatures are expected to decrease over some western coastal areas, on Sunday and Monday, March 9 and 10. Some coastal, western and island areas can expect light rainfall on Sunday and Monday.

What happens if rain interrupts play?

If bad weather halts play on March 9, the ICC has scheduled a Reserve Day (March 10). Any match stoppages will see play resume from where it left off.

What if the rain washes out both days?

Unlike the semifinals — where the higher-placed group team advanced—the final cannot be decided this way. If no play is possible on both days, India and New Zealand will share the trophy.

Fans, however, are hoping for clear skies. Team Indian and the Black Caps last clashed for the white-ball tournament final in 2000 when Champions Trophy was called the ICC Knockout Trophy. New Zealand claimed their first ICC title with a four-wicket win over India.
