This image is an interacting galaxy located in the direction of “Leo” taken by the Hubble Space Telescope. What is an interacting galaxy?By passing or collidingMultiple galaxies exerting the influence of gravity on each otherIt means that.

The spiral galaxy on the left is called “NGC 3227”, and the vague galaxy on the right is called the dwarf elliptical galaxy “NGC 3226”.Extraordinary GalaxyIn the catalog “Atlas of Peculi” (galaxies with unique morphology), these two galaxies are referred to as “”Arp 94It is recorded as.

Arp 94 does not show the large distortions of other peculiar galaxies in this image. However, evidence of induced star-forming activity and gas and dust flows indicate that the two galaxies are interacting. The relationships between galaxies that affect each other in this way (galaxy collisions, coalescence, passing, etc.) are not uncommon, and are considered to be one of the evolutionary processes of galaxies.

According to NASA, NGC 3227 is a type of active galaxy.Seyfert galaxyIt is classified as, and emits a strong electromagnetic wave from a narrow area in the center.Active Galactic Nucleus (AGN: Active Galactic Nucleus)Is said to exist. The driving force is thought to be a supermassive black hole, and this image is intended to analyze the movement of gas in the center of the galaxy and to investigate the mass of the black hole.
