An illustration by Andrei Sokolov for the 1967 book Zhdite Nas, Zvezdy (The Stars, They Await Us) by cosmonaut Alexei Leonov. It was later used as cover art for Nueva Dimensión #32 (May, 1972), where it apparently captured the interest of many Spanish-speaking sci-fi fans.
I got this information from el Blog Ausente with the help of Google Translate. Here is the English translation of the Spanish translation of the Russian caption to the image: “These transparent living organisms, like jellyfish, seem to float in the dense atmosphere of the planet of an alien star. The people at first take them for plants, but that is not so.”
