NEBLOGOSA














Nebulosa de emissão,
sem névoa, sem nuvem, sem bruma,
luz compósita da radiação estelar
em escultura de formas
fantasmáticas, fantásticas
da Central IC 1805.

O pasmo existe a cada momento
face a este mundo em silhueta.
E o que vejo é uma avestruz,
uma galinha, de longa crista
caminhando, articulada marioneta,
na majestade deste avistamento.


Joaquim Santos


Cosmic clouds seem to form fantastic shapes in the central regions of emission nebula IC 1805. Of course, the clouds are sculpted by stellar winds and radiation from massive hot stars in the nebula's newborn star cluster (aka Melotte 15). About 1.5 million years young, the cluster stars appear in this colorful skyscape, along with dark dust clouds silhouetted against glowing atomic gas. A composite of narrow band telescopic images, the view spans about 15 light-years and shows emission from hydrogen in green, sulfur in red, and oxygen in blue hues. Wider field images reveal that IC 1805's simpler, overall outline suggests its popular name - The Heart Nebula. IC 1805 is located about 7,500 light years away toward the constellation Cassiopeia.
