Hubble photographed a gas and dust cloud

The Hubble Mission Support Group has published a new colorful image. On it you can see a dense accumulation of gas and dust, known under the designation CB 130-3. It is located in the direction of the constellation Serpens.

Structures like CB 130-3 are interesting to study because they are the birthplaces of stars. For this, it is necessary that in some part of the cluster a sufficient amount of gas has gathered, having the necessary temperature and density to start fusion reactions. According to astronomers, deep inside CB 130-3 is a compact object balancing on the verge of becoming a full-fledged star.

It can be noted that CB 130-3 is an inhomogeneous object: its outer edges are not as dense as the center. The gas and dust that make up the cloud affects not only the brightness, but also the color of the background stars. The luminaries closer to the center of the cloud appear redder than their neighbors at the edges of the image. Astronomers used Hubble to measure this effect and plot the density of CB 130-3. This is necessary to obtain data on the internal structure of the stellar maternity home.
