Astronomers study as much of the spectrum of radiation as they can, and the visible spectrum is only a small segment of it.
No. It is electromagnetic radiation, beyond the violet end of the visible spectrum.
violet
Ultraviolet radiation is of higher energy than visible light. Ultra-violet suggests that it is above violet in the spectrum, and the colour violet is the uppermost region of visible light.
Visible light would be the light that is visible to our eyes in the spectrum, it goes in sequence: Red, Orange, Yellow, Green, Blue, Indigo, and Violet. The colors beyond red and violet are not visible to our eyes. Colors beyond red are known as Infrared, and colors beyond violet are known as ultraviolet.
By radiation, mostly infra red, visible, and ultra violet EM radiation
No. It is electromagnetic radiation, beyond the violet end of the visible spectrum.
violet
The visible spectrum between red and violet.
Ultraviolet radiation is of higher energy than visible light. Ultra-violet suggests that it is above violet in the spectrum, and the colour violet is the uppermost region of visible light.
By definition, ultra-violet light is outside the visible spectrum of EM radiation. Thus it is defined as invisible.
Ultra violet radiation has more energy (E=hf) than visible radiation.
A purely scientific answer is that there are no more colours beyond what you see in a rainbow. The rainbow constitutes the visible spectrum, meaning that it is the only part of the electromagnetic spectrum that is visible to the human eye as light. Beyond the red 'end' of the spectrum is Infra Red Radiation and beyond the violet 'end' is Ultra-Violet and beyond that X-rays. There is a Wikipedia article about the electromagnetic spectrum here: http://en.wikipedia.org/wiki/Electromagnetic_spectrum

Visible light
No. By definition, "ultraviolet" is that which is beyond the visible light - more specifically, beyond the violet part of visible light.
Ultra violet Infrared Visible light.....i think
Yes, it does. UV-C wavelength is 200-280 nanometers, UV-B is 280-320 nm, and UV-A is 320-400nm.
