The Hubble Space Telescope, from NASAin one of his exams of Spacecaptured an image of the molecular cloud of gas and dust, CB 130-3, located 652 light-years from Earth in the constellation Serpens, hosting a “project” of a nascent star.
According to the European Space Agency (ESA), these clouds serve as the building blocks for star formation. These clouds are thought to be stellar nurseries which can be the birthplaces of multitudes of stars, both singly and in binary pairs.

The new Hubble image shows the cloud looking like a glass of carrot juice poured onto a tablecloth of stars and galaxies. The image itself shows no sign that a star is in the process of forming. Other details about the cloud are more evident. The image demonstrates that the density of the molecular cloud is not constant.
Additionally, the outer edges of the phenomenon can be seen faintly, as wisps of gas that simply obscure the background stars. In stark contrast, the material at the center of the molecular cloud is so dense that it completely blocks out the light from the background stars.
Color can indicate a stellar nursery density
Gas and dust also affect the color of the stars behind it, as well as their brightness. Stars seen through thick material closer to the center appear to have taken on a redder hue than those shining through less dense material at the structure’s outer edges. This redness is the result of an interesting effect. The color shift can be used to map cloud density and provide a better understanding of the structure of this stellar nursery.
