Description:
Café Nobel (http://cafenobel.ujep.cz) je cyklus „přátelských setkání s vědou", který pořádá Univerzita Jana Evangelisty Purkyně v Ústí nad Labem (https://www.ujep.cz) ve spolupráci s magazínem Českého rozhlasu Sever Planetárium (https://www.rozhlas.cz/planetarium). Ve čtvrtek 19. září 2019 přednášel v rámci Café Nobel v prostorách Severočeské hvězdárny a planetária v Teplicích (http://www.hapteplice.cz) fyzik a astrofyzik prof. RNDr. Petr Kulhánek, CSc. Když se celá Země stane jedním velkým radioteleskopem, je možné pořídit nevídané snímky. Na jednom z nich se podařilo zobrazit obří černou díru v centru galaxie M87 s neuvěřitelným rozlišením 40 miliontin obloukové vteřiny. Takový snímek umožnil spatřit vnitřní část akrečního disku a stín vrhaný černou dírou. Díky přednášce Petra Kulhánka se opět přesvědčíte, že hranice technologických možností lidstva se neustále posouvá. Záznam obsahuje i část besedy, která po přednášce následovala. Medailonek přednášejícího: http://cafenobel.ujep.cz/kulhanek.html Partnerem Café Nobel je nakladatelství Academia (http://www.academia.cz).
