My hosting company got in touch to let me know that https wasn't enabled on an old tool I made with two friends back in 2009. I really appreciate both the person who got in touch with them about it and my hosting company for bothering to let me know. Thanks.

That tool is Chromoscope - a map of the astronomical sky (in Galactic coordinates) that lets you fade between different wavelengths of the electromagnetic spectrum from radio waves to gamma rays. chromoscope.net/

An image of the sky in Galactic Coordinates that is split up into gamma ray, optical light, far infrared, and microwave views. The most prominent feature through all four is the plane of the Milky Way across the middle.

We created it for the Royal Society Summer Exhibition in 2009 to demonstrate to members of the public that observing the Universe at different wavelengths tells us different things. In the years after the Royal Society event we were able to update and add various full sky surveys including from ESA's Planck (which two of us had worked on).

Originally there had been an idea to use Google's maps API but we found (early 2009) it wasn't up to the multi-tileset requirement as far as we could see. So I wrote my own "slippy map" code to let us do it.

At one point, in late 2009 I think, we were slashdotted and I got a very large (for me as a student) monthly bill from AWS for the tile serving. Cardiff Uni were kind enough to cover that for me.
