Unusual molecule found in atmosphere on Saturn’s moon Titan

Saturn’s largest moon, Titan, is the only moon in our solar system that has a thick atmosphere. It’s four times denser than Earth’s. And now, scientists have discovered a molecule in it that has never been found in any other atmosphere, CNN has reported.

The particle is called cyclopropenylidene, or C3H2, and it’s made of carbon and hydrogen. This simple carbon-based molecule could be a precursor that contributes to chemical reactions that may create complex compounds. And those compounds could be the basis for potential life on Titan, the CNN report says.

The molecule was first noticed as researchers used the Atacama Large Millimeter/submillimeter Array of telescopes in Chile. This radio telescope observatory captures a range of light signatures, which revealed the molecule among the unique chemistry of Titan’s atmosphere.

The study published earlier this month in the Astronomical Journal.

“When I realized I was looking at cyclopropenylidene, my first thought was, ‘Well, this is really unexpected,’” said lead study author Conor Nixon, planetary scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, in a statement.

Cyclopropenylidene has been detected elsewhere across our galaxy, mainly in molecular clouds of gas and dust including the Taurus Molecular Cloud. This cloud, where stars are born, is located 400 light-years away in the Taurus constellation. In these clouds, temperatures are too cold for many chemical reactions to occur.

Cyclopropenylidene has now been detected only in the Taurus Molecular Cloud and in the atmosphere of Titan.

But finding it in an atmosphere is a different story. This molecule can react easily when it collides with others to form something new. The researchers were likely able to spot it because they were looking through the upper layers of Titan’s atmosphere, where the molecule has fewer gases it can interact with.

“Titan is unique in our solar system,” Nixon said. “It has proved to be a treasure trove of new molecules.”

Cyclopropenylidene is the second cyclic or closed-loop molecule detected at Titan; the first was benzene in 2003. Benzene is an organic chemical compound composed of carbon and hydrogen atoms. On Earth, benzene is found in crude oil, is used as an industrial chemical and occurs naturally in the wake of volcanoes and forest fires.

Cyclic molecules are crucial because they form the backbone rings for the nucleobases of DNA, according to NASA.

“The cyclic nature of them opens up this extra branch of chemistry that allows you to build these biologically important molecules,” said study coauthor Alexander Thelen, an astrobiologist at Goddard, in a statement.

When the researchers discovered cyclopropenylidene in Titan’s atmosphere, they looked over data captured by NASA’s Cassini mission. The spacecraft performed 127 close flybys of Titan between 2004 and 2017. Cassini’s mass spectrometer detected a chemical signature of the same molecule, the researchers found.

“It’s a very weird little molecule, so it’s not going be the kind you learn about in high school chemistry or even undergraduate chemistry,” said c. Malaska was not involved with this study, but he researches Titan.

“Every little piece and part you can discover can help you put together the huge puzzle of all the things going on there.”

And discovering cyclopropenylidene on Titan adds to the moon’s intrigue.

Prime Minister Dr Harini Amarsooriya in her message on International Women’s Day 2026 says that the governments goal is to build a Thriving Nation where a woman can walk without fear or doubt, where her talents are duly recognized, and where she can lead a life of dignity.

The PM’s message:

“I extend my greetings to all sisters and daughters in Sri Lanka and around the globe on the occasion of International Women’s Day.This year, the United Nations has declared the global theme for International Women’s Day as “Rights. Justice. Action. For ALL Women and Girls,” emphasizing the realization of rights, the delivery of justice, and meaningful action for all women and girls.

Women are the true pillar of Sri Lankan society and economy. The role they play within the family and in society has today become a decisive factor in shaping the future of our nation. Through the Government’s policy statement, “A Thriving Nation – A Beautiful Life,” we envision going beyond treating women as mere beneficiaries and recognizing them as active partners in national development, ensuring that they receive the dignity and opportunities they rightfully deserve.

Within our policy framework, special focus has been placed on women. We are committed to recognizing the economic contribution extended by women as housewives, promoting women’s entrepreneurship, and expanding access to the technical and financial support necessary for self-employment alongside strengthening the legal framework required to ensure women’s safety in public transport, workplaces, and within the family environment. Further, we are taking steps to create the environment to increase women’s representation in decision-making bodies at national and regional levels. Special attention is also being given to implementing targeted programmes aimed at improving women’s nutrition, reproductive health, and mental well-being.

Women are not a group seeking sympathy; they are vital social partners endowed with intelligence, resilience, and creativity. Our goal is to build a “Thriving Nation” where a woman can walk without fear or doubt, where her talents are duly recognized, and where she can lead a life of dignity

On this International Women’s Day, I sincerely hope that it marks the beginning of a new era in which the aspirations of all women in our country are realized as they shine before the world.

Lanka tea industry may lose $ 10-15 mn per week from ME war

The ongoing military conflict in the Middle East has adversely impacted on the Sri Lankan tea industry as the exporters are unable to supply tea to the region. The exporters estimate the revenue loss at about $ 10-15 million per week. The exporters have orders in hand for supply of tea and it is the logistical issues and war risk preventing them fulfilling such orders, the Tea Exporters Association (TEA) said in a statement.

“In order to mitigate the impact on the industry, the tea industry has jointly requested the government to support it in addressing the cash flow issue and consider absorbing a part of the additional freight and insurance charges. It has also requested government intervention to obtain the balance payment of about $ 50 million due on tea shipments already made to Iran under the barter deal,” TEA said on Friday.

The statement said approximately 52% of Sri Lanka’s tea exports reach the affected region mainly coming from the low grown area of the country dominated by tea smallholder farmers. According to 2025 tea export statistics, about 125 million kilograms of Ceylon tea were exported to the Middle East, with an estimated value of USD 750 million. The major importing countries of Ceylon Tea in the region include Iraq, Iran, Libya, Turkey, Saudi Arabia, Syria, and the United Arab Emirates. Though Libya and Turkey can be reached via Africa, the exorbitant freight charges have prevented the buyers in those countries from importing tea at the moment.

The supply routes to Middle East countries go via Strait of Hormuz and Red sea Suez Canal. Although there is no blockade on Suez Canal, due to the war risk both channels are currently not used by the major shipping lines. The tea exports to the region have almost come to a standstill due to the following reasons:

=All major shipping lines suspended their services to the region immediately after the outbreak of the conflict.

=Several seaports in the region were temporarily closed during the initial stages.

= Although a few shipping lines resumed limited operations from March 4, freight charges have

increased significantly by approximately USD 1,800 for a 20’ container and USD 3,000 for a 40’ container.

= Existing insurance coverage obtained by exporters is no longer valid.

=There is a lack of regular and scheduled vessels operating from Colombo to Middle Eastern destinations.

The tea exporters are experiencing serious cash flow constraints, as payments for shipments already

dispatched have been delayed due to the unsettled situation in the region. This has restricted exporters’

buying capacity and that was evident at this week’s tea auction, where overall prices declined by about Rs. 50/ per kg while low grown tea prices declined by about Rs. 75/ per kg.

If the situation continues for few more weeks it will have a serious impact on the tea auction as buyers may curtail the purchase of tea if the outward movements are restricted. This could directly impact on the income of the tea smallholder farmers.

In January 2026, the country earned $ 121.8 million from tea exports compared to $ 112.7 million in January 2025 (a 5% increase). The figures for February 2026 are not yet available but should be either similar to last year or higher. The disruption to tea exports in March will certainly affect the volume and value of the exports though the exact amounts cannot be estimated at this point.

According to the available data Sri Lanka has settled about 95% of its debt to Iran by supplying tea to Iran under the Tea for Oil mechanism. Even if the military conflict comes to an end, Sri Lanka will find it difficult to continue to supply tea to Iran unless a new mechanism is introduced. Under the prevailing US sanctions on Iran, the exporters may not be able to supply tea to Iran outside the barter system. Iran purchases about 11 million kg of tea from Sri Lanka annually under the barter deal.

The situation was discussed with the Minister of Plantation & Community Infrastructure at a meeting held on March 4, 2026.
