I am trying to find a novella (and its follow up short story) that were published in "Isaac Asimov's Science Fiction Magazine" on the order of 20 years ago (+/- 5 years).
Premise: for reasons unknown, in contemporary times all the stars in the universe have gone out. The novella covers the whole thing, from the discovery past the end of the universe (it's complicated). The short story was more focused, was set before Earth's atmosphere had condensed to liquid. It made fun of CNN journalist Wolf Blitzer's name. Also, the Russians bombed their own rioting people in Moscow, and back in the US, there were neighbors mobbing the protagonists towards the end.
