A small, dense cloud of gas and dust called CB 130-3 smears the center of this image from the NASA/ESA Hubble Space Telescope. CB 130-3 is an object known as a dense core, which is a compact conglomeration of gas and dust. This very dense core is in the constellation of the Serpent and appears to flow through a field of background stars.

Dense cores such as CB 130-3 are home to stars and are of particular interest Astronomy scientists. As these cores collapse, enough mass can accumulate in one location to reach the temperatures and densities required to ignite hydrogen fusion, signaling the birth of a new star. While it may not be obvious from this image, a compact, swinging object is about to become a star embedded deep within CB 130-3.

Astronomers used Hubble’s Wide Field Camera 3 to better understand the environment around this newborn star. As this image shows, the density of CB 130-3 is not constant; The cloud’s outer edges are composed of only faint tufts, while at its core CB 130-3 completely blocks background light.

The gas and dust that make up CB 130-3 affects not only the brightness, but also the apparent color of the background stars, as the stars towards the center of the cloud appear redder than their counterparts on the outskirts of this image. Astronomers have used Hubble to measure this reddening effect and plot the intensity of CB 130-3, providing insight into the inner structure of this stellar nursery.
