NASA’s Hubble House Telescope captured this picture of the lenticular galaxy NGC 3489. Lenticular galaxies aren’t fairly spiral galaxies or elliptical galaxies. They lie someplace in between, exhibiting traits of each. Lenticular galaxies have a central bulge of tightly packed stars and a skinny, round disk of stars, gasoline, and dust, like spiral galaxies, however they lack arms. And like elliptical galaxies, lenticular galaxies have older stellar populations and little ongoing star formation.
NGC 3489 has an active galactic nucleus, or AGN. The AGN sits on the middle of the galaxy, is extraordinarily vibrant, and emits radiation throughout your complete electromagnetic spectrum because the black hole devours materials that will get too near it.
This lenticular galaxy is a Seyfert galaxy, which is a category of AGN that’s dimmer than different varieties of AGNs. They often do not outshine the remainder of the galaxy, so the galaxy surrounding the black hole is clearly seen. Different varieties of AGNs emit a lot radiation that it’s virtually unattainable to look at the host galaxy.
NGC 3489 is about 30 million light-years away within the constellation Leo.
