Historical black hole picture and ALMA observatory antenna accurately built in LEGO

Unless you have been living under a black hole, you have probably seen the historical picture of the supermassive black hole in the center of the M87 galaxy. Chilean builder Luis Peña was inspired by the results of the Event Horizon Telescope collaboration to build this new icon of science and the ALMA observatory, located in his home country. Luis loves science, and we have previously featured another historical event in science built by him, the Apollo/Soyuz meeting.

ALMA Observatory Antenna & Black Hole

The mosaic on the left displays the famous black hole radiowave picture, where the resolution of a 16×16 mosaic actually gives an accuracy almost comparable to the original. Speaking of accurate to the original, the dish of the radio antenna (one of 66 antennas in the observatory) is strikingly clean and parabolic, for the perfect focusing of captured light into the detector. The dish is stabilized by a white rigid hose, making a robust and accurate recreation.
