** M87 : Chandra Captures X-rays in Coordination with Event Horizon Telescope
The Event Horizon Telescope (EHT), a network of radio antennae around the globe, has captured the first image of a black hole event horizon. This black hole is located in Messier 87, or M87, which is about 60 million light years from Earth. Chandra has studied M87 many times over its 20-year mission and sees a much wider field-of-view than the EHT.

**Chandra Podcast: A Tour of the Teacup
Fancy a cup of cosmic tea? This one isn't as calming as the ones on Earth. In a galaxy hosting a structure nicknamed the "Teacup," a galactic storm is raging.
