Timeline photosTo celebrate 10 years of DECam operations, NOIRLab will hold an in-person community workshop in Tucson 12–14 September 2022. DECam is a wide-field imager installed at the Blanco Telescope in Cerro Tololo Inter-American Observatory, Chile. The workshop will highlight the outstanding DECam science results of the past 10 years, describe the exciting opportunities with DECam as we move into the era of the Vera C. Rubin Observatory/LSST and other new facilities, and look further into the future for the NOIRLab 4-meter telescopes. Registration is now open at noirlab.edu/science/events/websites/DECam/registration #DiscoverTogether

Timeline photosOur latest #ImageOfTheWeek is a 360-degree panorama featuring the #MilkyWay and several #nebulae within it arching above a number of #telescopes at Cerro Tololo Inter-American Observatory (CTIO), a Program of NSF's NOIRLab.

Various other, more unusual #nightsky phenomena are also visible. The white glow on the left of the image is zodiacal light, arising from interplanetary dust illuminated by the #Sun. The green, orange, and reddish “clouds” near the horizon are #airglow, caused by trace gasses in the upper atmosphere.

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.
