The European Southern Observatory (ESO) simply launched its picture of the week. This picture, acquired by the Very Massive Telescope (VLT) in Chile, reveals the RCW 36 nebula, positioned about 2,300 light-years away within the Vela Constellation. However to observers, it seems like a cosmic hawk spreading its wings: the darkish clouds on the heart resembling the hawk’s head and physique, and the filaments extending to the fitting and left serving because the wings. And in a pleasant twist, the picture itself was acquired by the High Acuity Wide-field K-band Imager-1 (HAWK-1) instrument on the VLT.
This high-performance, near-infrared imager is designed to seize deep, high-resolution pictures that permit it to penetrate the clouds of mud and gasoline that obscure dimmer objects, reminiscent of newly forming stars. A number of new stars are seen beneath the hawk within the picture, nestled amid clouds of nebula gasoline and dirt. The extraordinary radiation from these large younger stars illuminates the nebula, inflicting it to glow blue, pink, and white. Nevertheless, it’s the inhabitants of faint brown dwarfs that was of curiosity to the astronomers taking this picture.
Brown dwarfs are basically sub-stellar objects, very massive gasoline giants that weren’t large sufficient to endure gravitational collapse and fuse hydrogen. The HAWK-1 is ideally suited to this activity, combining excessive sensitivity with adaptive optics that appropriate for atmospheric interference. This allowed the worldwide staff, led by astronomers from the Instituto de Astrofĩsica e Ciências do Espaço (IA) in Lisbon, to establish the numerous fainter objects within the image. Their efforts are described in a paper that appeared in *Astronomy & Astrophysics*: “Substellar population of the young massive cluster RCW 36 in Vela.”
Along with offering important information that can enhance our understanding of how brown dwarfs kind, the research produced a placing picture. Afonso do Brito do Vale, a PhD scholar on the IA and the lead writer on the paper, described it as “large stars ‘pushing’ away the clouds of gasoline and dirt round them, nearly like an animal breaking by its eggshell for the primary time.” This completes the picture, giving the impression that the hawk is defending these child stars and brown dwarfs as in the event that they had been its eggs. Over time, new stars will “hatch” and be part of the nest!
