The National Aeronautics and Space Agency (NASA, for its acronym in English), has been chosen as “Astronomy Picture of day “to an image that captured a reflection nebula visible in the constellation Perseus” NGC1333 “, located 766 light years from Earth.
The picture was obtained by the telescope Cala d’Hort 500 mm of Spain thanks to the Astronomical Association of Ibiza. The credit is granted to the Alberto Rodriguez Prats
As explained on its website, 303 photographs from 2011 to 2014 were collected, supported LUMINANCE filters of red, green and blue, with the aim of achieving a greater contrast.
The last part of the work was to unite all the photographs of the hand of a specific program.
Meanwhile, NASA indicates that the image details that the nebula is “a dusty region where contrast red dots of emissions objects Herbig – Haro (ie, small nebulosity formed by the collision of gas ejected by young stars with materials around), jets and glowing gas emanating from stars recently formed “.
The US agency has estimated that the nebula” NGC-1333 “contains within hundreds of stars less than a million years, while the group of Ibiza said its estimate amount 150.
However, both agree that these stars, “most still not visible to optical telescopes by the pervasive nebula,” noting that the Sun may have formed 4 billion 500 million years ago ” .
