The word "news" is singular, uncountable. So you can't say "a news," instead you would say:

This is good news.

just as in "This is good water."

News itself is uncountable. Uncountable nouns don't take indefinite articles a and an; at least not directly. Let me explain.

So far, we understood that

This is *a good news.

is ungrammatical, while the latter form isn't. What if you do need to specify a one about news? That's where classifiers1 come into play.

A classifier, sometimes called a counter word, is a word or morpheme that is used to accompany nouns and can be considered to "classify" the noun depending on the type of its referent. - Wikipedia

The classifier for news, jewelry, meat, cake2 etc. is piece:

  • Sam just heard this shocking piece of news about the epidemic from the bus radio.

  • Pfft, this job is a piece of cake for a tough guy like you!

Thus, if you want to make your first sentence grammatical, use piece along with the indefinite article a:

This is a good piece of news.


1: Warning: Do not mix classifiers with noun classes. Inhaling the mixture might result in body inflammation and is highly toxic.
2: Also, a slice of cake.

    Don't forget: This is some good news. – J.R. Jun 15 '15 at 18:24

    Oh yes, @J.R. Also, this is the good news. I figured it might get a little off the question and make the answer unnecessarily long and TL;DR-worthy. – M.A.R. Jun 15 '15 at 18:25
