I was just thinking about how amazing rainbows are and how lucky we are that we can see them. But I was also wondering if other animals or hypothetical aliens that can see different spectra of light can also see something in the sky or is it just coincidentally just visible light?

You bet it does! The rainbow we see is a literally visible portion of a spectrum that is being projected. If a different portion were visible to us, we would see it in a different place – that’s why the colors are arranged from lowest to highest frequencies and with rainbows it should be especially easy to visualize how there are bands of invisible “colors” above and below a rainbow.
Perhaps even more fascinating, there are definitely refractions of invisible spectrums of light happening all the time around you that you’re just unaware of.
