The UAE’s Hope spacecraft has made a landmark discovery of a new type of aurora on Mars.
Scientists with the mission are calling it the "sinuous discrete aurora", a huge, worm-like aurora that extends halfway around the planet.
Aurorae are colourful lights that appear on a planet when solar activity disturbs its atmosphere.
On Earth, the aurora borealis and aurora polaris – known as northern lights – happens when protons and electrons from solar wind hit particles in the atmosphere, causing colourful lights in the sky.
On Mars, however, because of its lack of a global magnetic field and localised crustal magnetic fields in the southern hemisphere, there are three types of aurorae – proton, diffuse and discrete.
But the latest discovery has left scientists puzzled, creating new questions about the interactions between Mars’ atmosphere, the planet’s magnetic fields and the solar wind.
“When we first imaged Mars’ discrete aurora shortly after the Hope probe’s arrival at Mars in 2021, we knew we had unveiled new potential to make observations never before possible on this scale, and we took the decision to increase our focus on these auroras,” said Hessa Al Matroushi, science lead at the Emirates Mars Mission.
“We can obtain nearly whole-disc, synoptic snapshots of the atmosphere to investigate atmospheric phenomena and interactions. It means we are seeing discrete auroral effects on a massive scale and in ways we never anticipated.”
In June, the spacecraft captured the most detailed observations of the discrete aurora in Mars’ night side atmosphere.
Aurorae in Mars’ night side atmosphere are extremely rare to capture. However, Hope has a higher possibility of imaging the phenomenon than any other spacecraft because of its unique elliptical orbit around the planet. It observes the night side on each of its 55-hour orbits of the planet.
What is the new aurora?
The sinuous discrete aurora is made up of long worm-like streaks of energised electron emissions in the upper atmosphere.
These extend many thousands of kilometres, stretching from the day side into the night side of Mars.
The aurora was imaged when the planet was experiencing the effects of a solar storm, which caused a more turbulent stream of solar wind electrons than usual. This allowed Hope to capture the brightest and most extensive aurora it has observed so far.
Dr Rob Lillis, a Hope mission team member at the University of California, Berkeley, described the discovery. "The sinuous discrete aurora was a shocking discovery that in many ways has us scratching our heads and going back to the drawing board," he said.
“We have ideas but no solid explanation for why we are observing intense aurora of this shape and at planetary scales.
“We now have the opportunity to re-examine prior observations of Mars by missions such as Maven and Mars Express to search for signatures that could flesh out Hope’s new observations and perhaps help us try and unpick quite what is happening here.”
The spacecraft arrived at Mars' orbit on February 9, 2021 to study the planet's dynamic weather conditions and atmosphere.
Since then, thousands of science images have been released, as well as data that is available free of charge online.

Breast cancer in men: the facts
1) Breast cancer is men is rare but can develop rapidly. It usually occurs in those over the ages of 60, but can occasionally affect younger men.
2) Symptoms can include a lump, discharge, swollen glands or a rash.
3) People with a history of cancer in the family can be more susceptible.
4) Treatments include surgery and chemotherapy but early diagnosis is the key.
5) Anyone concerned is urged to contact their doctor

Day 4, Dubai Test: At a glance
Moment of the day Lahiru Gamage appeared to have been hard done by when he had his dismissal of Sami Aslam chalked off for a no-ball. Replays suggested he had not overstepped. No matter. Two balls later, the exact same combination – Gamage the bowler and Kusal Mendis at second slip – combined again to send Aslam back.
Stat of the day Haris Sohail took three wickets for one run in the only over he bowled, to end the Sri Lanka second innings in a hurry. That was as many as he had managed in total in his 10-year, 58-match first-class career to date. It was also the first time a bowler had taken three wickets having bowled just one over in an innings in Tests.
The verdict Just 119 more and with five wickets remaining seems like a perfectly attainable target for Pakistan. Factor in the fact the pitch is worn, is turning prodigiously, and that Sri Lanka’s seam bowlers have also been finding the strip to their liking, it is apparent the task is still a tough one. Still, though, thanks to Asad Shafiq and Sarfraz Ahmed, it is possible.

She was held in her native country a year later.
Dr Afridi's warning signs of digital addiction
Spending an excessive amount of time on the phone.
Neglecting personal, social, or academic responsibilities.
Losing interest in other activities or hobbies that were once enjoyed.
Having withdrawal symptoms like feeling anxious, restless, or upset when the technology is not available.
Experiencing sleep disturbances or changes in sleep patterns.
What are the guidelines?
Under 18 months: Avoid screen time altogether, except for video chatting with family.
Aged 18-24 months: If screens are introduced, it should be high-quality content watched with a caregiver to help the child understand what they are seeing.
Aged 2-5 years: Limit to one-hour per day of high-quality programming, with co-viewing whenever possible.
Aged 6-12 years: Set consistent limits on screen time to ensure it does not interfere with sleep, physical activity, or social interactions.
Teenagers: Encourage a balanced approach – screens should not replace sleep, exercise, or face-to-face socialisation.

Gender pay parity on track in the UAE
The UAE has a good record on gender pay parity, according to Mercer's Total Remuneration Study.
"In some of the lower levels of jobs women tend to be paid more than men, primarily because men are employed in blue collar jobs and women tend to be employed in white collar jobs which pay better," said Ted Raffoul, career products leader, Mena at Mercer. "I am yet to see a company in the UAE – particularly when you are looking at a blue chip multinationals or some of the bigger local companies – that actively discriminates when it comes to gender on pay."
Mr Raffoul said most gender issues are actually due to the cultural class, as the population is dominated by Asian and Arab cultures where men are generally expected to work and earn whereas women are meant to start a family.
"For that reason, we see a different gender gap. There are less women in senior roles because women tend to focus less on this but that’s not due to any companies having a policy penalising women for any reasons – it’s a cultural thing," he said.
As a result, Mr Raffoul said many companies in the UAE are coming up with benefit package programmes to help working mothers and the career development of women in general.
