De Nova Stella
Tycho Brahes nye stjerne
Særudstilling
Udstillingen kan opleves på Kroppedal Museum fra d. 3. februar til 30. april 2023
11. november 1572, for 450 år siden, observerede Tycho Brahe hvad han troede var en ny stjerne i konstellationen Cassiopeia. Han beskriver sine iagttagelser i bogen De Nova Stella i 1573, hvori han viser at den nye stjerne må være i den del af himlen, som ellers var troet uforanderlig. Således udfordrer Tycho Brahe samtidens verdensbillede, og bliver en af verdens vigtigste forskere.
Hvad han i virkeligheden så var dog ikke en ny stjerne, men en stjernes voldsomme død: en supernova.
Udstillingen åbner 3. februar kl. 14.00. Alle er velkomne til at deltage i åbningsreceptionen. Der er gratis adgang til alle museets udstillinger hele dagen.
I udstillingen udforskes både Tycho Brahes verden og videnskab, samt den moderne videnskab om supernovaer.
Udstillingen er skabt af SDU – Syddansk Universitetsbibliotek og Kroppedal Museum med støtte fra Fonden Dr. N. P. Wieth-Knudsens Observatorium
