In reality, the sooty-looking regions are actually vast swathes of #interstellar dust that block the passage of light, giving the illusion of empty regions in the band of the Milky Way.

Observações com a câmera DECam revelam a natureza de evento de ondas gravitacionais

October 16, 2017 1:52 pm

Cientistas usando a câmera do levantamento Dark Energy Survey (DES) capturaram imagens do resultado de uma colisão entre estrelas de nêutrons, evento que produziu a detecção de onda gravitacional mais recente (GW170817) pelos observatórios LIGO e Virgo. Uma equipe de cientistas usando a Dark Energy Camera (DECam), a principal ferramenta de observação do Dark Energy Survey, estão entre os primeiros a observar as consequências de um surto de ondas gravitacional detectado recentemente, registrando imagens da primeira explosão confirmada como consequência da fusão de duas estrelas de nêutrons. Esse violento processo de fusão, ocorrido há 130 milhões de anos em uma galáxia próxima à nossa (NGC 4993), é a fonte das ondas gravitacionais detectadas pelo Observatório Interferométrico de Ondas Gravitacionais (LIGO) e Interferômetro Virgo em 17 de agosto.
