Hello,

Suggest please whether the definite article is required/acceptable

within the highlighted area in the following sentence:

"Gases in the ionosphere are partly ionized by ... high-frequency
radiation from the Sun."

I would place "the" here; the book does not.

Thanks in advance.

I prefer to omit the article, but it would not be incorrect to include it.

If you were to omit the qualifier "from the sun," you obviously would not use the article. When you include the qualifier, you're specifying "which hf radiation," so the definite article is justified.

The - pertains to the sun's radiation. It requires the definite article.

I would still use [the] article. The- pertains to [the] energy from [the] sun.

You passed with flying colors, my friend.

Actually there were two definite articles involved in the discussion:
The radiation from the sun.

I was intending to weigh in on the side of omitting the first one in certain cases.

I have the feeling you may be difficult to persuade. Emotion: shake

Um...I have to admit, I favor using a definite article with 'radiation from the sun'. Simply, if I rephrase the question: what kind of radiation?, the need for the definite article is pretty clear.
