This NASA Hubble House Telescope picture reveals NGC 547, an elliptical galaxy that sits about 250 million light-years away from Earth within the constellation Cetus. NGC 547 shines just under the middle of this picture, with its companion galaxy NGC 545 close to the higher left. Collectively, the pair is called Arp 308.
NGC 547 is a vibrant radio galaxy, that means it has big areas of radio emission extending properly past its seen construction. The lobes of radio emission are powered by jets from the active galactic nucleus, or AGN, at its heart.
Galaxies with active galactic nuclei have an especially vibrant area at their cores the place a supermassive black hole exists. As dust and gasoline fall into the black hole it emits gentle throughout your entire electromagnetic spectrum.
Radio galaxies are one of the vital energetic astrophysical phenomena. Hubble noticed this galaxy as a part of a survey for a dataset meant to assist in persevering with exams of scientific theories about AGNs.
