A team of astronomers managed to capture a detailed and colorful image of the RCW 38 star cluster, in the constellation of Vela, at 5,500 years The light of the Earth, with the help of infrared wave system HAWK-I, reported the European Southern Observatory (ESO).
The infrared-wave device installed in the long-range telescope (VLT) located in Parbad, Chile, provided a clear picture of this young group of stars surrounded by clouds Intensely glossy and detailed gas, with traces of black dust in the form of a vine around the nucleus
The central zone is shown as a region dyed blue and inhabited by many young, hot stars and mbadive, as well as stars that are still forming.
The radiation emitted by the stars makes the gas shine intense, unlike the colder cosmic dust currents that cross the region and shine in the dark shades of red and orange.
Although there are previous images of this region, these were obtained by length-length wavelengths of the visible range, which provides images with fewer star bodies, because dust and gas block the view of the cluster.
The HAWK-I, on the other hand, allows to look through the dust bands by means of observations with the infrared, the same that allows to obtain images of nearby galaxies, large nebulae, individual stars and exoplanets.
To obtain a clear image, the GRAAL adaptive optics module played an important role. laser beams, projected into the night sky, act as artificial reference stars to correct the effects of atmospheric turbulence.
The image was captured as part of a set of experimental observations, known as scientific verification, of the two devices, installed in the long-range telescope.
The European Southern Observatory is an intergovernmental scientific and technological organization operating from three sites, recognized for their quality of observation, located in the desert Chilean of Atacama: La Silla, Parbad and Chajnantor.
The VLT is a set of four "unitary telescopes", each with a primary mirror of 8.2 meters in diameter, with which it was possible to obtain images of celestial objects barely visible of a magnitude of 30, which equates to seeing objects that are four billion times weaker than those seen at a glance.
