If the artist would have just added a few melting clocks onto those Venusian lava fields we'd have a truly surreal masterpiece.

The Persistence of Memory (Spanish: La persistencia de la memoria) is a 1931 painting by artist Salvador Dalí. The well-known surrealist piece epitomizes Dalí's theory of "softness" and "hardness", which was central to his thinking at the time. As Dawn Adès wrote, "The soft watches are an unconscious symbol of the relativity of space and time, a Surrealist meditation on the collapse of our notions of a fixed cosmic order". This interpretation suggests that Dalí was incorporating an understanding of the world introduced by Albert Einstein's theory of special relativity. Asked by Ilya Prigogine whether this was in fact the case, Dalí replied that the soft watches were not inspired by the theory of relativity, but by the surrealist perception of a Camembert melting in the sun.

It is possible to recognize a human figure in the middle of the composition, in the strange "monster" (with much texture near its face, and much contrast and tone in the picture) that Dalí used in several contemporary pieces to represent himself – the abstract form becoming something of a self-portrait, reappearing frequently in his work. The creature seems to be based on a figure from the Paradise section of Hieronymus Bosch's The Garden of Earthly Delights, which Dalí had studied. It can be read as a "fading" creature, one that often appears in dreams where the dreamer cannot pinpoint the creature's exact form and composition. One can observe that the creature has one closed eye with several eyelashes, suggesting that the creature is also in a dream state. The iconography may refer to a dream that Dalí himself had experienced, and the clocks may symbolize the passing of time as one experiences it in sleep or the persistence of time in the eyes of the dreamer.

The orange clock at the bottom left of the painting is covered in ants. Dalí often used ants in his paintings as a symbol of decay. Another insect that is present in the painting is a fly, which sits on the watch that is next to the orange watch. The fly appears to be casting a human shadow as the sun hits it. The Persistence of Memory employs "the exactitude of realist painting techniques" to depict imagery more likely to be found in dreams than in waking consciousness.

The craggy rocks to the right represent a tip of Cap de Creus peninsula in north-eastern Catalonia. Many of Dalí's paintings were inspired by the landscapes of his life in Catalonia. The strange and foreboding shadow in the foreground of this painting is a reference to Mount Pani.>>

I agree completely. As far as I remember the illumination at the surface of Venus would be like an overcast day here on Earth. The thick cloud layer would not allow the disk of the Sun to be ever visible, let alone at sunset.

The possibility of airborne microbial Venusians is certainly exciting, but currently controversial.

We find that the published 267-GHz ALMA data provide no statistical evidence for phosphine in the atmosphere of Venus.

That's the last sentence of today's explanation. The last link in that sentence to the word controversial brings up a paper on a study looking more carefully for the supposed biomarker PH₃ in the Venusian atmosphere. The study's conclusion reads:

We find that the published 267-GHz ALMA data provide no statistical evidence for phosphine in the atmosphere of Venus.

So all that excitement over "Life on Venus!" was about something that there really is no evidence in support of at all.

Thanks, Bruce. My initial reaction to the claim that there might be life in the atmosphere of Venus was skepticism. I agree that we can't know that such life is impossible, but I have to chime in with Carl Sagan:

Extraordinary claims require extraordinary evidence.

I'm actually not asking for extraordinary evidence from those that claim that there may be life in the atmosphere of Venus. But a good bit more evidence than they have presented so far would be nice.
