Coalsack

Nebulosa oscura en la constelación de la Cruz del Sur.

Reduce el brillo de las estrellas ubicadas detrás de ella en 1 a 1,5 magnitudes. Fácilmente visible por contraste contra el cielo estrellado, está probablemente a unos 550–600 años–luz de la Tierra y tiene un diámetro de 20–30 años–luz. Aparece en las leyendas de los pueblos del hemisferio sur y es conocida por los europeos desde 1500. El Coalsack del norte, en la constelación del Cisne, es similar en naturaleza y apariencia, pero es menos notoria.
