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?

WHAT IS A BLACK HOLE?
1. Black holes are objects whose gravity is so strong not even light can escape their pull
2. They can be created when massive stars collapse under their own weight
3. Large black holes can also be formed when smaller ones collide and merge
4. The biggest black holes lurk at the centre of many galaxies, including our own
5. Astronomers believe that when the universe was very young, black holes affected how galaxies formed

Where to donate in the UAE
The Emirates Charity Portal
You can donate to several registered charities through a “donation catalogue”. The use of the donation is quite specific, such as buying a fan for a poor family in Niger for Dh130.
The General Authority of Islamic Affairs & Endowments
The site has an e-donation service accepting debit card, credit card or e-Dirham, an electronic payment tool developed by the Ministry of Finance and First Abu Dhabi Bank.
Al Noor Special Needs Centre
You can donate online or order Smiles n’ Stuff products handcrafted by Al Noor students. The centre publishes a wish list of extras needed, starting at Dh500.
Beit Al Khair Society
Beit Al Khair Society has the motto “From – and to – the UAE,” with donations going towards the neediest in the country. Its website has a list of physical donation sites, but people can also contribute money by SMS, bank transfer and through the hotline 800-22554.
Dar Al Ber Society
Dar Al Ber Society, which has charity projects in 39 countries, accept cash payments, money transfers or SMS donations. Its donation hotline is 800-79.
Dubai Cares
Dubai Cares provides several options for individuals and companies to donate, including online, through banks, at retail outlets, via phone and by purchasing Dubai Cares branded merchandise. It is currently running a campaign called Bookings 2030, which allows people to help change the future of six underprivileged children and young people.
Emirates Airline Foundation
Those who travel on Emirates have undoubtedly seen the little donation envelopes in the seat pockets. But the foundation also accepts donations online and in the form of Skywards Miles.

Libya's Gold
UN Panel of Experts found regime secretly sold a fifth of the country's gold reserves.
The panel’s 2017 report followed a trail to West Africa where large sums of cash and gold were hidden by Abdullah Al Senussi, Qaddafi’s former intelligence chief, in 2011.
Cases filled with cash that was said to amount to $560m in 100 dollar notes, that was kept by a group of Libyans in Ouagadougou, Burkina Faso.
A second stash was said to have been held in Accra, Ghana, inside boxes at the local offices of an international human rights organisation based in France.
