The search for alien life has always fascinated humanity, driving scientists to explore beyond our solar system.
One of the most promising methods in this quest involves studying the climates of exoplanets, or planets that orbit stars outside our solar system.
Climate patterns on these distant worlds can offer clues about their potential to harbour life, particularly by examining their atmospheric composition.
Stanimir Metchev, a professor at the Institute for Earth and Space Exploration at Western University, Canada, said that certain gases in the atmosphere suggest whether or not that planet possibly hosts life.
“For life as we know it on Earth, we look for gases that support life or indicate its presence: oxygen or ozone, water vapour, methane (produced by biological decay), and carbon dioxide,” he told The National.
“Among these, the most telling pair is oxygen plus methane. Normally, they react very efficiently, until one of them is completely depleted from the atmosphere.
“If both are observed to exist at the same time, as they do in Earth’s atmosphere, then both are being produced at present: oxygen through photosynthesis and methane through decay.”
He said that the combination of oxygen and methane in an exoplanet’s atmosphere is “perhaps the strongest indicator of life as we know it”.
Insights from the TRAPPIST-1 System
The TRAPPIST-1 system, located about 39 light-years from Earth, has become a focal point in the search for habitable exoplanets.
This system features seven Earth-sized planets, three of which are in the habitable zone, where conditions might be right for liquid water to exist.
“TRAPPIST-1 has multiple rocky planets, three of which are potentially habitable. Similar, cool, and small stars, called red dwarfs, may be the best chance for us to find life in the near future,” Prof Metchev said.
“These kinds of stars account for three-quarters of all stars in our galaxy and are now also known to commonly host multiple rocky planets.
“So, most Earth-sized planets in our galaxy reside around stars like TRAPPIST-1.”
Scientists have been using the James Webb Space Telescope – the most powerful space observatory launched in 2021 – to study the TRAPPIST-1 system.
Recent findings from the telescope have shown that the inner planets in TRAPPIST-1 likely do not have thick, hydrogen-rich atmospheres, suggesting that they are more like terrestrial planets with thin atmospheres, similar to Venus and Mars.
However, the outer planets could have water, either as atmospheric vapour or ice, depending on their distance from the star.
Powerful Telescopes
The James Webb Space Telescope has unique instruments that help measure the light that passes through exoplanets or that is emitted by them when they pass in front of or eclipse their host stars.
This planet transiting technique allows scientists to study the atmospheres of the planets.
“It may even offer us the first chance to detect biosignature gases on an exoplanet: it could be one of the TRAPPIST-1 planets or another Earth-sized planet in the habitable zone of a similar nearby red dwarf star,” said Prof Metchev.
“Webb is also allowing us to study some very bright and widely separated giant exoplanets directly, and we are now finding that they have clouds (although made of hot sand, rather than water vapour).
“However, Webb cannot yet give us the much-desired direct image of an Earth-like exoplanet.”
He said that the Habitable Worlds Observatory will allow scientists to directly study the atmospheres of Earth-like planets, without having to rely on the transiting planet technique.
The observatory, which is being planned by Nasa, aims to study 25 potentially habitable worlds.
It will use spectroscopy to search for chemical biosignatures in these planets’ atmospheres, such as oxygen and methane.
Each discovery will help scientists get closer to answering one of humanity’s most profound questions: are we alone in the universe?

Evacuations to France hit by controversy
- Over 500 Gazans have been evacuated to France since November 2023
- Evacuations were paused after a student already in France posted anti-Semitic content and was subsequently expelled to Qatar
- The Foreign Ministry launched a review to determine how authorities failed to detect the posts before her entry
- Artists and researchers fall under a programme called Pause that began in 2017
- It has benefited more than 700 people from 44 countries, including Syria, Turkey, Iran, and Sudan
- Since the start of the Gaza war, it has also included 45 Gazan beneficiaries
- Unlike students, they are allowed to bring their families to France

What is tokenisation?
Tokenisation refers to the issuance of a blockchain token, which represents a virtually tradable real, tangible asset. A tokenised asset is easily transferable, offers good liquidity, returns and is easily traded on the secondary markets.
Mercer, the investment consulting arm of US services company Marsh & McLennan, expects its wealth division to at least double its assets under management (AUM) in the Middle East as wealth in the region continues to grow despite economic headwinds, a company official said.
Mercer Wealth, which globally has $160 billion in AUM, plans to boost its AUM in the region to $2-$3bn in the next 2-3 years from the present $1bn, said Yasir AbuShaban, a Dubai-based principal with Mercer Wealth.
“Within the next two to three years, we are looking at reaching $2 to $3 billion as a conservative estimate and we do see an opportunity to do so,” said Mr AbuShaban.
Mercer does not directly make investments, but allocates clients’ money they have discretion to, to professional asset managers. They also provide advice to clients.
“We have buying power. We can negotiate on their (client’s) behalf with asset managers to provide them lower fees than they otherwise would have to get on their own,” he added.
Mercer Wealth’s clients include sovereign wealth funds, family offices, and insurance companies among others.
From its office in Dubai, Mercer also looks after Africa, India and Turkey, where they also see opportunity for growth.
Wealth creation in Middle East and Africa (MEA) grew 8.5 per cent to $8.1 trillion last year from $7.5tn in 2015, higher than last year’s global average of 6 per cent and the second-highest growth in a region after Asia-Pacific which grew 9.9 per cent, according to consultancy Boston Consulting Group (BCG). In the region, where wealth grew just 1.9 per cent in 2015 compared with 2014, a pickup in oil prices has helped in wealth generation.
BCG is forecasting MEA wealth will rise to $12tn by 2021, growing at an annual average of 8 per cent.
Drivers of wealth generation in the region will be split evenly between new wealth creation and growth of performance of existing assets, according to BCG.
Another general trend in the region is clients’ looking for a comprehensive approach to investing, according to Mr AbuShaban.
“Institutional investors or some of the families are seeing a slowdown in the available capital they have to invest and in that sense they are looking at optimizing the way they manage their portfolios and making sure they are not investing haphazardly and different parts of their investment are working together,” said Mr AbuShaban.
Some clients also have a higher appetite for risk, given the low interest-rate environment that does not provide enough yield for some institutional investors. These clients are keen to invest in illiquid assets, such as private equity and infrastructure.
“What we have seen is a desire for higher returns in what has been a low-return environment specifically in various fixed income or bonds,” he said.
“In this environment, we have seen a de facto increase in the risk that clients are taking in things like illiquid investments, private equity investments, infrastructure and private debt, those kind of investments were higher illiquidity results in incrementally higher returns.”
The Abu Dhabi Investment Authority, one of the largest sovereign wealth funds, said in its 2016 report that has gradually increased its exposure in direct private equity and private credit transactions, mainly in Asian markets and especially in China and India. The authority’s private equity department focused on structured equities owing to “their defensive characteristics.”

How will Gen Alpha invest?
Mark Chahwan, co-founder and chief executive of robo-advisory firm Sarwa, forecasts that Generation Alpha (born between 2010 and 2024) will start investing in their teenage years and therefore benefit from compound interest.
“Technology and education should be the main drivers to make this happen, whether it’s investing in a few clicks or their schools/parents stepping up their personal finance education skills,” he adds.
Mr Chahwan says younger generations have a higher capacity to take on risk, but for some their appetite can be more cautious because they are investing for the first time. “Schools still do not teach personal finance and stock market investing, so a lot of the learning journey can feel daunting and intimidating,” he says.
He advises millennials to not always start with an aggressive portfolio even if they can afford to take risks. “We always advise to work your way up to your risk capacity, that way you experience volatility and get used to it. Given the higher risk capacity for the younger generations, stocks are a favourite,” says Mr Chahwan.
Highlighting the role technology has played in encouraging millennials and Gen Z to invest, he says: “They were often excluded, but with lower account minimums ... a customer with $1,000 [Dh3,672] in their account has their money working for them just as hard as the portfolio of a high get-worth individual.”
