If peoples eyes could see ultraviolet light, what would humans observe?

If peoples eyes could see ultraviolet light waves, what would humans observe in the world and solar system about us?

Would people being able to view ultraviolet electromagnetic energy reveal a whole new Earth and Universe?

How would our Sun look like? Could we see anything amazing in space? Would other humans look different?

Earths plasmasphere viewed in ultraviolet light

If people could see in ultraviolet light (UV light) then this is a rough idea of what the Earths plasmasphere would look like to them (if they were in space).

Eta Carinae stars ultraviolet LASER light

This is currently the only star thought to emit natural LASER light in ultraviolet wavelengths.
Eta Carinae | wikipedia

Have you heard about the great LASER light show in the sky? A team led by K. Davidson (U. Michigan) and S. Johansson (U. Lund) discovered that the chaotically variable star Eta Carinae emits ultraviolet light in such a narrow band that it is most probably LASER light! This artist's vision depicts a model that could account for their Hubble Space Telescope observations. In this model, Eta Carinae emits many LASER beams from its surrounding cloud of energized gas. Infrared LASERS and microwave MASERS are extremely rare astrophysical phenomena, but this natural ultraviolet LASER is the first of its kind to be discovered.
