Astronomers working with the Hubble telescope have published a new image of the object of deep space. This time the target of the space observatory was the galaxy NGC 5248.
NGC 5248 is located 42 million light-years from Earth toward the constellation Boötes. It is classified as a grand-design galaxy. Such objects are characterized by the presence of powerful, pronounced and well-shaped arms that clearly emanate from their center. About 10% of all spiral galaxies are believed to be of this type. Due to their “perfect” structure, they are considered the archetype of spiral galaxies.
In addition, at the center of NGC 5248, between the inner ends of the spiral arms, there is a faint bar. It is not as prominent in this portrait obtained by Hubble in visible light. Such structures have a huge impact on the movement of matter in the galaxy and ultimately on its evolution. They are a kind of fuel pipeline, bringing gas from the outer regions to the center. There it becomes raw material for the formation of new stars, and can also be absorbed by the black hole.
These gas flows gave NGC 5248 its characteristic appearance. There are many bright areas scattered across the disk of the galaxy, which seem to sparkle. These are regions of active star formation dominated by populations of young luminaries.
The core of NGC 5248 is also surrounded by two rings composed of young star clusters. As a rule, such structures prevent gas from penetrating into the galactic center. The fact that NGC 5248 has a ring within a ring suggests how powerful the flows of matter and energy are.
Earlier we told you about how Hubble photographed a stellar nursery.
