Summary edit
| Description |
Português: O objetivo do artigo é divulgar as fotografias astronômicas feitas pela expedição brasileira enviada a Sobral para registrar o eclipse total do Sol de 29 de maio de 1919. Uma rica coleção de fotografias, na maioria inéditas, disponíveis em suporte de placas de vidro, encontra-se na Biblioteca do Observatório Nacional. A fotografia ocupou lugar central na astronomia do século XX. O eclipse de Sobral ganhou repercussão mundial devido à comprovação da teoria da relatividade geral pelas expedições inglesas. Neste texto ressaltamos a participação dos astrônomos do Observatório Nacional no evento, pois foram os primeiros brasileiros a ter sucesso na obtenção de fotografias da coroa solar.
English: The objective of this article is to disseminate the astronomical photographs taken by the Brazilian expedition sent to Sobral (state of Ceará) to record the total eclipse of the Sun on May 29, 1919. There is a rich collection of photographs, most unpublished, available on glass plates stored in the Library of the Observatório Nacional. Photography was central to astronomy in the twentieth century. Thus, while the eclipse in Sobral had worldwide repercussions due to the proof of the theory of general relativity by the English expeditions, in this article we highlight the participation of astronomers from the Observatório Nacional at the same event, since they were the first Brazilians to successfully obtain photographs of the Sun’s corona. |
