Code	/ EHT and the Quest for M87 / // by megamanwhiz // /* An entry to the Impossible Images contest I've been programming 36(ish) months, and I have learned 100% of Intro to JS. / /* Additional Information / //{ / * Technically, black holes cannot be imaged since they absorb all light. The picture taken is actually the shadow of the black hole, not the black hole itself. The brighter the color, the faster the matter is moving. * To give a scale, the event horizon (The place where light is able to escape the black hole) of the black hole in M87 is about half a light-day across, or around the size of the solar system. * The Event Horizon Telescope was first imagined by German radioastronomer Heino Falcke in 1993. It began collecting data in 2006. By 2017, more telescopes had joined the array from around the world. It was actually very challenging to align all the scopes, but once they were and once the weather permitted, the EHT gathered 5 petabytes of data over a week in April 2017. This data has been analyzed very rigourously, and came out on April 10, 2019 as the image I replicated here. IF you have any questions, ask in the T&T below and I will try to answer them. I am not an expert though, so I'd advise you to check out EHT's website in the credit section.
