TFA specifies "more than 1,500 billion". That's more than a _trillion_, not "billions"! Why the reluctance to use the proper number?

The UK used a different definition of trillion until ~50 years ago (10^18 vs 10^12), so it probably helps avoid ambiguity

The designation of trillion is ambiguous: https://en.wikipedia.org/wiki/Trillion

Same for one billion: https://en.wikipedia.org/wiki/Billion

I've never heard someone use the long scale, it is only ever mentioned as a novelty. I think the scientific community, at the very least, has standardized on the short scale.

Billions is not wrong. Trillions (plural) would be wrong. "More than a trillion" would be needless words.

The long scale is common in French, German and Spanish for example. English usually uses the short scale. The scientific community uses SI prefixes, which aren't part of either scale (you don't say a billion joules which is ambiguous, you either say a terajoule for a long-scale billion or a gigajoule for a short-scale one).

...I was under the impression that there was a faint blue glow coming from everywhere, that was hypothesized to be extra galactic stars. Has there been any follow up on that?

A very famous person is very well known for his particular style of enunciating billions. After that, saying any other word is just a wasted chance of having Sagan's voice in their head reading the word.
