Both a star's diameter and its radiation vary widely from one star to another. Look at the data for our Sun, for an example - but consider that this is not exactly typical, in the sense that other stars can be much bigger or smaller, and radiate much more, or much less, energy, than our Sun.
In the stable state a star's diameter and radiation remains the same for millions of years...:)
remain the same... :)
Infrared radiation is long wavelength radiation given out by stars.
they are magnetic
if you mean what is the source of radiation in space the he answer is it comes from stars in most of their lifespan
Mass similar to our own Milky Way; about a trillion stars; diameter estimated at 140,000 light-years.Mass similar to our own Milky Way; about a trillion stars; diameter estimated at 140,000 light-years.Mass similar to our own Milky Way; about a trillion stars; diameter estimated at 140,000 light-years.Mass similar to our own Milky Way; about a trillion stars; diameter estimated at 140,000 light-years.
They can be. Stars are very hot and can emit harmful amounts of radiation. At the same time, without stars there would be no life.
remain the same... :)
diameter is from on side to the end and radiation is half of the diameter.

That sounds like the description of a quasar. Those are related to active supermassive black holes.
xray radiation and ultraviolet radiation
There are huge variations in a star's diameter. Our Sun has a diameter of about 1.4 million kilometers, but a few stars have hundreds of times this diameter - and of course, some stars are smaller than our Sun. It is hard to say what is "normal" with such huge variations, but probably the majority of stars are a little smaller than our Sun.There are huge variations in a star's diameter.

Not on the Earth.

Electromagnetic Radiation requires no medium. Light is a form of electromagnetic radiation, and it can traverse the stars.
they are magnetic
