NASA telescope snaps a beautiful galaxy that hosts supermassive black hole

To conclude Black Hole Week, NASA on Friday shared this mesmerizing image of a luminous galaxy that contains an active galactic nucleus. NGC 5283 is a Seyfert galaxy that stands out among other galaxies hosting active galactic nuclei (AGNs) due to the distinctive feature that the galaxy itself is clearly visible.

In contrast, many AGNs emit such intense radiation that it overwhelms or obscures the structure of their host galaxies, making it difficult to observe them directly.

An AGN refers to a compact and highly energetic region at the centre of a galaxy where a supermassive black hole exists. As matter in the form of dust and gas gets drawn towards the black hole, it undergoes intense heating, resulting in the emission of light spanning the entire electromagnetic spectrum.

Scientists study AGNs to better understand the processes of galaxy formation and evolution, as they play a significant role in regulating the growth of galaxies and shaping their properties.

The specific observation of NGC 5283 is part of a survey focused on collecting a dataset of nearby AGNs. This dataset serves as a valuable resource for astronomers investigating various aspects of AGN physics, black holes, the structure of host galaxies, and other related topics.
