This is Amazing Stories for September 1940, cover by Robert Fuqua. The ISFDB entry for this issue is here. I found this version of the cover at Pulp Covers, which also provides us with a back cover:
The included text there is something to behold: “Life on Europa (moon of Jupiter). This member of the solar system is only slightly smaller than Earth’s moon. Science knows little about it, and thus, lacking conclusive observation, our artist pictures its life in imaginative style (see page 144 for details).” Sure, why not?

This is Amazing Stories for January 1942, cover by Malcolm Smith. The ISFDB entry for this issue is here. While far from the first instance of the artistic trope of a “tube girl,” I do think it might have been this particular illustration that motivated the proprietor of of the (apparently) now-defunct blog Promethean Blues to coin the term “tube girl,” whence I have taken it. I found this version of the cover at Pulp Covers. You can download and read this entire issue from the Internet Archive.

My original tumblr post was here. This image was researched by Bacchus at ErosBlog as part of the “Δ commission.” The research was originally published at Hedonix as “Δ 045 X-Ray Tubes.” Here is what Bacchus found.
The Tumblr post at the origin of this animation’s Tumblr chain of provenance includes the following tags: “#1950s scifi #this island earth #1955 #joseph m newman”. The reference is to the 1955 sci-fi movie This Island Earth, which was notable at the time for its special effects and for being filmed in Technicolor.
According to the plot summary at Wikipedia, the two protagonists are at one point menaced with being subjected to a “Thought Transference Chamber”, which might be the chamber visible in the animation.
The attribution to This Island Earth is confirmed by the following scene from the trailer, which shows the same two people in the same sort of chambers, albeit with a menacing robot in this frame not directly seen (but visible as a shadow/silhouette) in the animation:
In 1996 the movie This Island Earth was heavily reworked (it’s unclear from Wikipedia whether it was completely remade or whether it was heavily cut and intercut with new footage) and released to theaters as Mystery Science Theater 3000: The Movie. From the Wikipedia plot summary it seems unlikely that the animation stems specifically from the new MST3K movie footage, but I was unable to rule out the possibility.

This artwork is cropped from the covers of an Eerie Mysteries magazine:
This page suggests that only four issues of Eerie Mysteries ever appeared, in 1938 and 1939. It appears (although the scan is indistinct) that the cover above may be from the February 1939 issue. No artist information seems to be available, although it is known that Norman Saunders illustrated the cover of the August 1938 issue.

This comic book art is the top panel in the story A Nation Is Born in Avon’s Strange Worlds #4 (1952) which (according to the Wikipedia entry on Strange Worlds) featured a Wallace “Wally” Wood cover:
A post on Pulpcovers.com offers a link for downloading a .cbz-format download of the entire comic.
A blog post here features a differently-colored version of the page where this image appeared, along with the information that the story was illustrated by Rafael Astarita and was reprinted in Strange Planets #9 (1959):
The script for A Nation Is Born was adapted for Volume 1, No. 8 of a black-and-white comic series called Strange Galaxy, where it appeared in 1971 in black and white (supposedly to avoid Hayes Code rules applicable to color comics) as The Moon Is Red:
