Crescent Shadow of Messier 87’s Supermassive Black Hole is Wobbling 0

In 2019, the Event Horizon Telescope (EHT) delivered the first resolved images of M87*, the supermassive black hole in the center of the giant elliptical galaxy Messier 87 (M87). Those images were produced using EHT observations performed in April 2017. Additional observations were required to investigate the persistence of the primary image feature and to quantify the image variability. To address this need, astronomers analyzed M87* data collected with the proto-EHT array of telescopes in 2009, 2011, 2012, and 2013. The analysis reveals the behavior of the black hole image across this period, indicating persistence of the crescent-like shadow feature, but also variation of its orientation — the crescent appears to be wobbling.

Mars, also known as the red planet, has been the focus of numerous research studies, as some of its characteristics have sparked discussions about its possible inhabitability. The National Aeronautics and Space Administration (NASA) and a few other space agencies have thus sent a number of rovers and other spacecraft to Mars with the hope of better understanding its geology and environment.
