Glossary term: Astrônomo

Description: Um astrônomo estuda os objetos que compõem o Universo. Os astrônomos podem ser profissionais ou amadores. Os astrônomos profissionais e alguns astrônomos amadores analisam dados científicos obtidos por meio de telescópios na Terra e no espaço para responder a perguntas sobre a composição dos objetos no cosmos, sua distribuição, evolução e futuro. Com essas informações, os astrônomos formulam novas teorias que explicam o que vemos no Universo, desde as pequenas até as grandes escalas. Alguns astrônomos amadores observam o céu simplesmente para admirar as maravilhas do Universo. Na prática, não há diferença entre um astrônomo profissional e um astrofísico. Na astronomia moderna, as observações profissionais estão sempre ligadas a tentativas de modelar os processos físicos que produzem os fenômenos que estão sendo observados, e o treinamento de nível universitário em astronomia inclui o conhecimento de física relevante como parte do curso.

Two astronomers view a lunar eclipse. Between them in the partly cloudy sky, a series of bright circles trace a curved path

The Eclipse Between Us, by Muhammad Rayhan, Indonesia

Caption: Second place in the 2021 IAU OAE Astrophotography Contest, category Total lunar eclipse. Total lunar eclipses belong to the rather spectacular celestial events and can be observed easily with and without a telescope. Here we see the stages of the total lunar eclipse of 31.1.2018 photographed in Indonesia: starting with the entry of the full moon disk into Earth's round umbra, the totality as Blood Moon, and the beginning of the Moon's exit from Earth's umbra until moonset.
