Researchers from MIT and Harvard University have developed a new algorithm that could help astronomers produce the first image of a black hole. The algorithm would stitch together data collected from radio telescopes scattered around the globe in an international collaboration called the Event Horizon Telescope. The project seeks, essentially, to turn the entire planet into a large radio telescope dish.
Zooming in on black holes is the main mission for the newly installed GRAVITY instrument at ESO’s Very Large Telescope in Chile. During its first observations, GRAVITY successfully combined starlight using all four 1.8-metre Auxiliary Telescopes. The first observations using GRAVITY with the four 8-metre VLT Unit Telescopes are planned for later in 2016.
