You should at least say why most astronomy is done in Near IR as opposed to optical wavelengths.
Most Astronomers want to do science, optics just tell you what something looks like and the nature of light that reflects off of it. It doesn’t tell you what it is made of. Things that generate photons, Xrays, gamma rays, radio frequencies, et al tell you what stuff out there is made of.
