Independent: Venus Could Have Completely Alien Lifeforms in Cloud Layer

December 21, 2021

The Independent has published a piece by Adam Smith reporting that scientists at Cardiff University, MIT and Cambridge University have modelled a series of chemical reactions based on a ammonia, which would neutralise sulfuric acid droplets. Venus has a lethal atmosphere of mostly carbon dioxide, where it rains sulfuric acid, and an atmospheric pressure and temperature much higher than Earth. Probes sent to the planet have lasted only a few minutes after landing because of the immensely harsh conditions. However, as the article states, ammonia has also been detected in its atmosphere, that might indicate that it has life. The article states that this would be ‘unlike anything we’ve seen’, which sounds like there could be large creatures moving around in the planet’s cloud layer. Unfortunately, as the article goes on to say, if life exists it’s going to be microbes, but microbes of a very different biochemistry. The article begins:

‘Researchers believe that there could be potential lifeforms producing ammonia in the clouds of Venus that are “very unlike anything we’ve seen”.

The colourless gas, a compound of nitrogen and hydrogen, could be indicative of chemical reactions that would make the planet – 47.34 million kilometres from Earth – more habitable to alien life.

On our planet, ammonia is a common left-over waste from aquatic organisms. Its presence in Venus’ upper atmosphere has been puzzling astronomers since the 1970s – with scientists believing that it should not be produced by any known force on the world.

Venus itself is so hot that it is inconceivable to have life forms, and if there is life in the clouds it is likely to be microbes like Earth bacteria – albeit with a chemical composition unlike that we have seen on our planet, or even neighbouring planets like Mars.

This is because life on Mars is more likely to be similar to that on Earth and so scientists have a greater idea of what to expect. Venus, in contrast, is unlike any other planet in the solar system.

In a new study, researchers from Cardiff University, MIT and Cambridge University modelled a set of chemical processes to show that – if ammonia is indeed present – it would set off a cascade of chemical reactions that would neutralize surrounding droplets of sulfuric acid.’


This is interesting, and Venus certainly has the organic chemistry necessary for life, and I think the temperature and pressure in the cloud layer is roughly suitable. But I’m pessimistic about there being life on Venus. We haven’t found it elsewhere in the solar system yet, although it could be preserved in refugia deep in the rocks and artesian wells on Mars or in the subterranean oceans believed to be under Jupiter’s moon Europa. But I’m not confident of its existence there, either. We were disappointed when the Mariner probe got to Mars in the 1960s, and found that instead of being roughly like Earth, it was more like the Moon. Before then, astronomers had observed seasonal changes of colour on the planet, and suggested it was due to changes in vegetation, possibly mosses and lichens. And then, of course, there was speculation about Martian canals in the 19th and early 20th centuries. There may yet be life in the solar system. I hope so, but I’m not confident. And the only way to find out is to go there. Until then, we’ll have to wait and see, whatever planet it’s on it.

Mars as Communist Utopia in Pre-Revolutionary Russian SF

June 7, 2018

I thought this might interest all the SF fans out there. One of the books I’ve started reading is Lost Mars: The Golden Age of the Red Planet, edited by Mark Ashley (London: The British Library 2018). It’s a collection of SF stories written about the Red Planet from the 19th century to just before the Mariner and then Viking probes in the ’60s and ’70s showed that rather than being a living planet with canals, vegetation and civilised beings, it was a dead world more like the Moon. It’s a companion volume to another book of early SF stories from about the same period, Moonrise: The Golden Age of Lunar Adventures, also edited by Mike Ashley. The Martian book contains stories by H.G. Wells, Ray Bradbury – from The Martian Chronicles, natch – Marion Zimmer Bradley, E.C. Tubb, Walter M. Miller, and the great novelist of dystopias and bug-eyed psychopaths, J.G. Ballard. It also contains pieces by now all but forgotten Victorian and early Twentieth writers of Scientific Romances, W.S. Lach-Szyrma, George C. Wallis, P. Schuyler Miller and Stanley G. Weinbaum.

Both books are also interesting, not just for the short stories collected in them, but also for Ashley’s introduction, where he traces the literary history of stories about these worlds. In the case of the Moon, this goes all the way back to the Roman satirist, Lucian of Samosata, and his Vera Historia. This is a fantasy about a group of Roman sailors, whose ship is flung into space by a massive waterspout, to find themselves captured by a squadron of Vulturemen soldiers from the Moon, who are planning an invasion of the Sun.

The history of literary speculation about Mars and Martian civilisation, is no less interesting, but somewhat shorter. It really only begins in the late 19th century, when telescopes had been developed capable of showing some details of the Martian surface, and in particular the canali, which the Italian astronomer Schiaparelli believed he had seen. The Italian word can mean ‘channels’ as well as ‘canal’, and Schiaparelli himself did not describe them as artificial. Nevertheless, other astronomers, like Percival Lowell of Flagstaff, Arizona, believed they were. Other astronomers were far more sceptical, but this set off the wave of novels and short stories set on an inhabited Mars, like Edgar Rice Burrough’s famous John Carter stories. I remember the Marvel adaptation of some these, or at least using the same character, which appeared as backing stories in Star Wars comic way back in the 1970s.

It’s also interesting, and to contemporary readers somewhat strange, that before H.G. Wells’ War of the Worlds, the vast majority of these stories about Mars assumed that the Martians would not only be far more scientifically and technologically advanced, but they would also be more socially and spiritually as well. Just like the Aetherius Society, a UFO new religious movement founded by George King in the 1950s, claims that Jesus was really as Venusian, and now lives on that world along with Aetherius, the being from whom they believe they receive telepathic messages, so there were a couple of short stories in which Christ was a Martian. These were Charles Cole’s Visitors From Mars, of 1901, and Wallace Dowding’s The Man From Mars of 1910.

Other utopias set on the Red Planet were more secular. In Unveiling a Parallel, by Alice Ilgenfritz Jones and Ella Merchant, of 1893, the Martians are handsome and intelligent, and their women totally liberated. Another feminist utopia was also depicted by the Australian writer Mary Moore-Bentley in her A Woman of Mars of 1901.

And in Russia, the writer Alexander Bogdanov made Mars a Communist utopia. Ashley writes

While the planetary romance theme was developing there were other explorations of Martian culture. The Red Planet became an obvious setting for a communist state in Krasnaia Zvesda (‘Red Star’, 1908) and its sequel Inzhener Menni (‘Engineer Menni’, 1912) by Alexander Bogdanov. Although reasonably well known in Russia, especially at the time of the revolution in 1917, and notoriously because of its reference to free love on Mars, it was not translated into English until 1984. Kim Stanley Robinson claimed it served as an influence for his own novel, Red Mars (1992), the first of his trilogy about terraforming the planet. Although the emphasis in Bodganov’s stories is on the benefits of socialism, he took trouble to make the science as realistic as possible. The egg-shaped rocket to Mars is powered by atomic energy. His Mars is Schiaparellian, with canals that have forests planted along their full length, explaining why they are visible from Earth. He also went to great lengths to explain how the topography of Mars, and the fact that it was twice as old as Earth, allowed social evolution to develop gradually and more effectively, with planet-wide communication and thus a single language. (Pp. 11-12).

So five years before the Revolution, Mars really was the ‘Red Planet’ in Russian literature. I’m not surprised it wasn’t translated into English until the 1980s. British publishers and censors probably disliked it as a piece of Communist propaganda, quite apart from Anglophone western Puritanism and the whole issue of free love. No naughtiness allowed on the side of the Iron Curtain, not even when it’s set on Mars. Russian cinema also produced one of the first SF films, also set on Mars. This was Aelita (1922), in which Russian cosmonauts travel to the Red Planet to start a revolution, though at the end it’s revealed that it’s all been a dream.

Meanwhile, Mars as a planet of mystery continues in the French SF series, Missions, shown at 10.00 Thursdays on BBC 4. This has French spationauts and their American rivals landing on the Red Planet, only to find a mysterious altar constructed from lost Atlantean materials described by the Romans, and Vladimir Komarov, a Soviet cosmonaut, who has been turned into something more than human with three strands of DNA. In reality, Komarov died when the parachutes on his spacecraft failed to open when it re-entered the Earth’s atmosphere. Tragically, Komarov knew it was a deathtrap, but went anyway because Khrushchev wanted another Russian space achievement to show up the Americans, and Komarov did not want his friend, and first man in space, Yuri Gagarin to go. It’s a tragic, shameful waste of human life on what was a purely political stunt, and Komarov is, because of his desire to save his friend, one of the great heroes of the space age.

But Missions shows not only how much people really want us to travel to Mars – to explore and colonise – it also shows how the Red Planet still remains the source of wonder and speculation about alien civilisations, civilisations that may not be hostile monsters intent on invading the Earth ‘for no very good reason’, as Douglas Adams described the motives of those aliens, who wanted to take over the universie in The Hitch-Hiker’s Guide to the Galaxy. One of the French spationauts, Jeanne, has dreamed of going to Mars since being shown it through a telescope by her father when she was a little girl. Electromagnetic scans of the area, when developed, give a picture of her face, and ‘Komarov’ tells her he has been waiting millions of years for her, and she is the true link between Mars and Earth.

Yes, it’s weird. But different. And it shows that Mars is continuing to inspire other forms of SF, where the Martians aren’t invaders – or at least, not so far-but benevolent guides waiting for us to come to them and make the next leap in our development. Just like Bogdanov in 1912 imagined that they would be ahead of us, and so have created a true Communist utopia.
