I was working at a radio station as an intern that day, and remember being both horrified at what had happened, and excited to be among the first to see the news coverage as it came in.

This is a misunderstanding of the phenomenon of “Kessler syndrome”, which isn’t a discrete event but rather a state in which a substantial density of debris in a particular orbit will be in a self-sustaining condition, generating more debris through impacts with other spacecraft and objects in orbit. This will continue until the entire orbital azimuth is essentially cleared (by objects and debris falling out of orbit through natural decay or by a hypothetical method of debris removal). In the lowest part of Low Earth Orbit (LEO) i.e. below 500 km the orbital lifetime of an object in a near circular orbit will be on close order of a year (depending on solar activity effects on thermospheric drag and the ballistic coefficient for that regime) but at the higher end of LEO the decay time can be on the order of hundreds or even thousands of years. Objects in more eccentric orbits may have shorter or longer orbital lifespans depending on how long they spend in the thicker parts of the thermosphere but bear in mind that as debris falls out of one orbit it falls into lower orbits and spreads across a broad range of azimuths into the path of objects that cross the trajectory of the slowly decaying debris. A an accidental Kessler syndrome (or intentional cascade from attacks on multiple satellites in different azimuths or dispersal of debris) at the mid-to-upper range of LEO could produce effective denial of orbital space and make even access to upper orbits and interplanetary space extremely risky for the foreseeable future.
I hope astronomers are watching this star closely now:
One of the largest known stars in the universe underwent a dramatic transformation in 2014, new research shows, and may be preparing to explode.
A study led by Gonzalo Muñoz-Sanchez at the National Observatory of Athens, published in Nature Astronomy today, argues that the enormous star WOH G64 has transitioned from a red supergiant to a rare yellow hypergiant – in what may be evidence of impending supernova.
The evidence suggests we may be witnessing, in real time, a massive star shedding its outer layers, shrinking as it heats up, and moving closer to the end of its short life.
I’m not sure how long such a process might take, and perhaps the experts don’t either. I suppose the very last bit happens quickly, but perhaps we are talking thousands of years until then.
