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.

A meeting between Prime Minister Dr. Harini Amarasuriya and a delegation of UNICEF representatives was held on Saturday, (December 20) at the Prime Minister’s Office.

During the meeting, the Prime Minister explained the measures taken by the Government to ensure the protection of the affected student community and to restore the damaged school system, as well as the challenges encountered in this process.

The Prime Minister stated that reopening schools located in landslide-prone areas would be extremely dangerous. Accordingly, the Government is focusing on identifying such schools and relocating them to suitable locations based on scientific assessments.

The Prime Minister further noted that financial assistance has been provided to students affected by the disaster, enabling parents to send their children back to school without an additional financial burden. Emphasizing that school is the safest place for children after their homes, the Prime Minister expressed confidence that the school environment would help restore and improve students’ mental well-being

The Prime Minister also highlighted that attention has been given to several key areas, including the relocation of disaster-affected schools, restoration of school infrastructure, merging and operating certain schools jointly, facilitating teaching and learning through digital and technological strategies, and providing special transportation facilities. She emphasized that the Government is examining these issues and is committed to finding long-term solutions.

The UNICEF representatives commended the Government’s commitment and the initiatives undertaken to restore the education sector and assured their support to the Government. Both parties also discussed working together collaboratively on future initiatives.

The meeting was attended by the UNICEF representatives to Sri Lanka Emma Brigham, Lakshmi Sureshkumar, Nishantha Subash, and Yashinka Jayasinghe, along with Secretary to the Ministry of Education Nalaka Kaluwewa, Director of Education Dakshina Kasturiarachchi, Deputy Directors Kasun Gunarathne and Udara Dikkumbura.

NMRA laboratory lacks SLAB accreditation

Drug controversy:

“Setting up state-of-the-art drug testing facility will cost Rs 5 billion”

Activists call for legal action against politicians, bureaucrats

Serious questions have been raised over Sri Lanka’s drug regulatory system following revelations that the National Medicines Regulatory Authority’s (NMRA) quality control laboratory is not accredited by the Sri Lanka Accreditation Board (SLAB), casting doubt on both the reliability of local test results and the adequacy of oversight of imported medicines.

Medical and civil rights groups warn that the issue points to a systemic regulatory failure rather than an isolated lapse, with potential political and financial consequences for the State.

Chairman of the Federation of Medical and Civil Rights Professional Associations, Specialist Dr. Chamal Sanjeewa, said the controversy surrounding the Ondansetron injection, which was later found to be contaminated, had exposed deep weaknesses in drug regulation and quality assurance.

Dr. Sanjeewa said that the manufacturer had confirmed that the drug had been imported into Sri Lanka on four occasions this year, despite later being temporarily withdrawn from use. The drug was manufactured in India in November 2024 and in May and August 2025, and imported to Sri Lanka in February, July and September. On each occasion, 67,600 phials were procured.

Dr. Sanjeewa said the company had informed the NMRA that the drug was tested in Indian laboratories, prior to shipment, and passed all required quality checks. The manufacturer reportedly tested the injections against 10 parameters, including basic quality standards,

pH value, visual appearance, component composition, quantity per phial, sterility levels, presence of other substances, bacterial toxin levels and spectral variations.

According to documents submitted to the NMRA, no bacterial toxins were detected in the original samples, and the reported toxin levels were within European safety limits of less than 9.9 international units per milligram.

Dr. Sanjeewa said the credibility of local regulatory oversight had come under scrutiny, noting that the NMRA’s quality control laboratory was not SLAB-accredited. He said establishing a fully equipped, internationally accredited laboratory would cost nearly Rs. 5 billion.

He warned that the failure to invest in such a facility could have grave consequences, including continued loss of life due to substandard medicines and the inability of the State to recover large sums of public funds paid to pharmaceutical companies for defective drugs.

“If urgent steps are not taken, public money will continue to be lost and accountability will remain elusive,” Dr. Sanjeewa said.

He added that if it was ultimately confirmed that the drug did not contain bacterial toxins at the time it entered Sri Lanka, the fallout would be even more damaging, severely undermining the credibility of the country’s health system and exposing weaknesses in health administration.

Dr. Sanjeewa said public trust in the health sector had already been eroded and called for legal action against all politicians and public officials responsible for regulatory failures linked to the incident.
