Material ejected from the star has cleared out cavities above and below it, whose boundaries glow orange and blue in this infrared view. As the collapse continues, an increasing amount of gas impacts the disk rather than the star, a consequence of angular momentum conservation. Getting pictures of these objects is hard, because they remain covered in dust As illustrated below, protostars continue to collapse, releasing gravitational energy as they shrink and grow continually denser. ‘baby’ planet photographed in a ring around a star for the first time! Many different wavelengths of light are combined and represented by separate and various colors.
