As can be seen from these frames from this video and this video, Space Invaders has a vertically oriented monitor which makes scan lines appear vertically, not horizontally. .
The CRT display is mounted facing upwards, reflected towards a semi-transparent mirror, behind which is a plastic cutout of the planetary surface. The reflection of the CRT appears over the cutout, serving as a backdrop. The CRT had colored overlays on the display itself, to add color to the black and white image. Thus, both the colors and background of Space Invaders are non-digital optical effects. Also note that the actual CRT image is mirrored to appear correct in the reflection.

I adore the little animations where the invader steals and flips the Y in PLAY, and the red invader shooting the extra C in INSERT COIN.
