I was hooked by the first few paragraphs of this Jacey Fortin article in the NY Times:
If you happen to be in Canada on a clear night, look to the stars and maybe you’ll see it: a strip of light stretching from east to west, all the way from the banks of Hudson Bay to the fjords of British Columbia.
Is it a wayward piece of the aurora borealis? Or maybe a plane’s contrail? A rarely seen strip of a proton aurora? Or is it a comet’s tail?
Actually, it’s none of the above. Scientists are still working to figure out exactly what they’re dealing with.
And until that day, they’re going to call it Steve.
