The first horizon scaale image of a black hole from the APOD site

This is the first "horizon scale" image of a black hole. It was created using a "world sized" radio telescope.

Images are mainly found via APOD (click any image for more information). Others may be taken direct from NASA, ESA or via Wikipedia.

Development of the site was done using Visual Studio Code, node.js/npm, live-server.

The CSS for this site should have been courtesy of PaperCSS and indeed was for the initial development, but then I found that PaperCSS doesn't work with IE11 or Edge so after some (failed) debugging, the site moved to vanilla (at the time of writing) Bootstrap 4 quite quickly. CSS info for "Off site" links found via electrictoolbox and much information found over the years via stackoverflow of course.

The separate CSS used for IE8 and IE9 is very basic but adequate - maybe that should be 'functional'.

Initially the site is pure HTML/CSS and only Bootstrap JS, but it will be converted to NodeJS/express as time allows.
