Why would you want something shorter, that was a nice piece of writing.
Of course cruel to just leave us hanging there.
It's fine writing, but upon visiting the linked article, I had no idea what it was. No indication of author or intent, or even if it was fiction or non. I was half-expecting an Asimovian plot twist revealing that the Nemesis would next appear later that very day!
By the time I finished it I thought it was the first chapter from Asimov's Nemesis and was very disappointed. Except I didn't remember it to be so well written...
