The sun gives out raidio waves = radiation lol notrealy :)
The Sun and red giants
All types of radiation can travel through space.
gravity
if you mean what is the source of radiation in space the he answer is it comes from stars in most of their lifespan
Electromagnetic radiation that comes from outer space are called, Cosmic Rays.
All objects give off thermal radiation.
All objects give off thermal radiation.

No, different objects give out different heat radiations.
A 'ray' is a term for a radiation. All objects with temperatures above 0 degrees Kelvin give off radiation called, "Heat".
True , because the warmer objects give off more infrared radiation than cooler objects ..
all objects emit electromagnetic radiation through empty space, as well as matter. So feel the heat from the electric heater due to radiation.
yes every object gives out thermal radiation
Lots of space objects give of some X-rays, but probably the strongest signals are from Quasars.
They study visible light by using optical telescopes.
Infrared radiation can only travel through empty space or transparent objects
Yes a nuclear bomb gives radiation. Radiation is transfer of energy through empty space.
