The First Picture of a Black Hole in History !
The global project “Event Horizon Telescope” (EHT) was focusing on two black holes through several worldwide-spanning radio telescopes over years. Finally, it could make this picture from an ultra-massive black hole from the galaxy Messier 87. It is the first time humankind could make a picture from a black hole. This achievement is comparible only with the historical moment of moon landing.
According to news, observations show that jets are fired out of the newly discoversd Black Hole Messier M87 which “are moving at greater than 99% the speed of light” (https://www.universetoday.com/144520/m87s-black-hole-is-firing-out-jets-that-travel-99-the-speed-of-light). This analysis had been done by using x-ray data.
