Heber Doust Curtis Livres
Heber Doust Curtis était un astronome américain dont les recherches se sont concentrées sur les éclipses solaires et les nébuleuses. Son travail de pionnier dans l'observation du cosmos comprenait la première identification d'un jet polaire émanant de Messier 87. Curtis a considérablement fait progresser notre compréhension de l'univers, plaidant notamment pour l'existence de galaxies au-delà de notre propre Voie Lactée. Ses approches innovantes de l'étude astronomique et de ses techniques d'observation ont laissé un héritage durable dans le domaine.
