Physicist: At the risk of being a smart-ass; it really depends on what you want to see.
Andromeda, the nearest galaxy to the Milky Way, as seen in the infrared, radio, visible, and x-ray parts of the spectrum.
Different wavelengths are good for seeing different things. Infrared is good for seeing dust, x-rays are good for finding blackholes, novas, and bones. You want to see stars and pretty much nothing else? Radio waves.
So the short answer is that there’s no best spectrum for seeing stuff. But given the choice, I personally would go with x-ray vision.
Just out of interest, are those red blobs on the radio spectrum single super-bright stars? Or maybe globular clusters?
Also interesting how the galaxy looks more like a ring+central blob than a spiral there.
They’re most likely to be clusters. Generally when a single star is bright enough (in any part of the spectrum) to rival the brightness of the galaxy as a whole, it’s in the middle of blowing up.
“But given the choice, I personally would go with x-ray vision.”But you’d need a friendly helper to carry an x-ray generator that’d enable you to once in a while see more than black. At least on our world…
Wouldnt a better question be “what would it be like to see in all sprectrums”
If its possible that is
