| Summary:
|
Polovina Nobelovy ceny za fyziku byla v roce 2020 udělena Reinhardu Genzelovi a Andree Ghez za nepřímá pozorování superhmotné černé díry v centru Mléčné dráhy. Skupiny Genzela a Ghez totiž od devadesátých let pozorovaly orbitální dynamiku hvězd v našem galaktickém centru, z níž byly schopné vydedukovat přítomnost nesmírně hmotného a kompaktního tělesa, které hvězdy přitahuje. K tomu ale nejdříve musely vyvinout nové techniky pozorování, například tzv. adaptivní optiku, či mít "štěstí na hvězdy", které černou díru obíhají. To vše, včetně nejnovějšího vývoje v pozorování z roku 2018, je shrnuto v tomto článku. (Czech) |
