M87* One Year Later: Proof of a Persistent Black Hole Shadow

The Event Horizon Telescope (EHT) Collaboration has released new images of M87*, the supermassive black hole at the center of the galaxy Messier 87, using data from observations taken in April 2018.

With the participation of the newly commissioned Greenland Telescope and a dramatically improved recording rate across the array, the 2018 observations give researchers a view of the source independent from the first observations in 2017.
