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.

Bangladesh bank on bowlers in bid to bring India down

Bangladesh will look to curb Shafali Verma's aggression [cRICINFO]

If Bangladesh take the route of seeking inspiration from the past to bring down heavyweights India on Thursday, they will have to squint their eyes and go back to pre-Covid times for their last victory against them in the Women’s Asia Cup. India have had the better of their neighbours over their last eight meetings, and last lost to Bangladesh in a T20I three years ago, when a very similar-looking Indian batting line-up was kept to 102 for 9.

Before that, Bangladesh had shocked India with back-to-back wins that culminated in their maiden Asia Cup title, by again stifling India to an underwhelming 112 for 9.

The Bangladesh team of today – as their recent fights have shown over the last two World Cups – is a version far improved from the ones of 2018 and 2023. They have scared teams like Australia and England (ODI World Cup) and India (T20 World Cup) in the last 12 months and they recently beat the higher ranked Pakistan in the UK by keeping them to 100 for 8.

It is this bowling strength that Bangladesh must bank on to try and bring down India, whose batting has stuttered every now and then, including a collapse of 8 for 46 against Thailand earlier in the tournament. India have had middle-order issues for a while now – it’s one of the things that kept them from a knockout berth in the last T20 World Cup – and Bangladesh will be itching to strike while the iron is hot.

They have laid the foundations in the last 10 days by routing Indonesia for 58, making Sri Lanka sweat in a chase of 115, and suffocating UAE’s batters to 69 for 9 with semi-finals qualification on the line.

Pratika Rawal, India’s No. 3 for this tournament in place of the injured Jemimah Rodrigues, hasn’t quite shown the promise in this format that she has in ODIs. Her 36 runs in three innings have come at a strike rate of just 109.09, against some of the lower-ranked teams in the world. Now into the knockouts, the time is ripe for Rawal to step up against one of the stronger bowling attacks of the tournament, especially if one of the openers doesn’t get going.

Swing bowler Marufa Akter is doing Marufa Akter things at this Asia Cup. She has struck in her opening spell in each of her three games so far – including the big scalp of Chamari Athapathuthu for 1. She has made the ball talk with her prodigious swing, and is the top wicket-taker in this Asia Cup among pace bowlers, with an economy rate of 3.27. She will hold the key for Bangladesh as they come up against a top order comprising Smriti Mandhana, Shafali Verma and Rawal.

Team news

After constant chopping and changing during the T20 World Cup in the UK, India have gone unchanged in the three games of this tournament. They will be expected to field the same XI again.

India (probable): Smriti Mandhana, Shafali Verma, Pratika Rawal, Harmanpreet Kaur (capt), Richa Ghosh (wk), Bharti Fulmali, Deepti Sharma, Prema Rawat, Kranti Gaud, N Shree Charani, Nandani Sharma.

Bangladesh have used 14 players, in comparison, including a debut for 17-year-old allrounder Farjana Easmin. They may not make too many changes this time as the two players who came into the XI on Tuesday – Rabeya Khan and Sharmin Akter – played starring roles in beating UAE.

Bangladesh (probable): Juairiya Ferdous, Nigar Sultana (capt & wk), Sobhana Mostary, Dilara Akter, Shorna Akter, Rabeya Khan, Sharmin Akter, Nahida Akter, Sultana Khatun, Marufa Akter, Fahima Khatun.
