Approaching a small black hole would tear you apart by tidal forces until you were just a string of particles being sucked in. We call this spaghettification. Bon appétit! #DarkBites

The Dark Energy Survey

Congratulations to the many collaborators of the Event Horizon Telescope Project for this historic accomplishment!You are looking at the first ever image of a black hole, captured by the Event Horizon Telescope Project. Within the dark spot is the black hole—a place so gravitationally dense nothing can escape from it, not even light. The orange halos surrounding the hole are hot gas emissions, swirling around it under the influence of the strong gravity near the event horizon—the point past which not even light can escape before falling into the void.

To capture this image, a network of telescopes around the globe coordinated efforts to observe the black hole that sits at the center of Messier 87, a massive galaxy in the nearby Virgo galaxy cluster, 55 million light-years from Earth. This effort to create an “Earth-sized” telescope resulted in five petabytes of data (“the equivalent of billions of cat videos” according to EHT researchers) which researchers refined to create this historic first image.

The National Science Foundation played a pivotal role in this discovery by funding individual investigators, interdisciplinary scientific teams and radio astronomy research facilities since the inception of EHT. Over the last two decades, NSF has directly funded more than $28 million in EHT research, the largest commitment of resources for the project

The biggest mystery of studying the cosmic web with DES is why my code takes so darn long to run. Actually, it isn't a mystery when you analyze 18 million galaxies! #DEST4TD

Thanks to Brandon Buncher (University of Illinois at Urbana-Champaign) for today's DES thought for the day!

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.
