| Abstract from DBPedia | An astronomer is a scientist in the field of astronomy who focuses their studies on a specific question or field outside the scope of Earth. They observe astronomical objects such as stars, planets, moons, comets and galaxies – in either observational (by analyzing the data) or theoretical astronomy. Examples of topics or fields astronomers study include planetary science, solar astronomy, the origin or evolution of stars, or the formation of galaxies. A related but distinct subject is physical cosmology, which studies the Universe as a whole.天文学者（てんもんがくしゃ、英: astronomer）とは、惑星、恒星、銀河等の天体を研究する学者や科学者である。 (Source: http://dbpedia.org/resource/Astronomer) |
