Black Hole Image Makes History; NASA Telescopes Coordinated Observations
A black hole and its shadow have been captured in an image for the first time, a historic feat by an international network of radio telescopes called the Event Horizon Telescope (EHT). EHT is an international collaboration whose support in the U.S. includes the National Science Foundation...
The stunning new image shows the shadow of the supermassive black hole in the center of Messier 87 (M87), an elliptical galaxy some 55 million light-years from Earth. This black hole is 6.5 billion times the mass of the Sun. Catching its shadow involved eight ground-based radio telescopes around the globe, operating together... https://www.nasa.gov/mission_pages/chandra/news/black-hole-image-makes-history

Tačno, svetlosna godina je jedinica mere za daljinu, a godina za vreme.
Svetlosna godina je rastojanje koje svetlost pređe za jednu godinu.
Ako je crna rupa na rastojanju od 55 miliona svetlosnih godina, onda je svetlosti trebalo 55 miliona godina da od te crne rupe stigne do nas.
Priča o dva najveća znanstvena otkrića 21. stoljeća, ispričana riječima nevjerojatnih znanstvenika koji su ih i ostvarili. Prvo je LIGO-ovo mjerenje gravitacijskih valova koji potječu od spajanja crnih rupa, a drugo slika crne rupe koju je snimio EHT (Event Horizon Telescope).
