It seems to me that from an accessibility standpoint the background
image is not an issue. It is basically a "decorative" image, without
any substantive content, and so does not need an ALT value.

Actually, the issue that I see is with the ALT value of the "logo.png"
image. You have the ALT specified as "Universe Logo". Since the image
has text in it, typically the ALT would be the same as the text, so
the ALT ought to be "Marvin Hunkin", or possibly "Marvin Hunkin logo,
an image of moons circling a planet" if you want to give a more
complete description.

That's my take on it anyway.
