A new image from the American Space Agency’s Hubble Space Telescope (NASA) of IC 4271, also known as Arp 40, shows a curious pair of spiral galaxies about 800 million light-years away.
As detailed by NASA, the smaller galaxy is superimposed on the larger one, which is a type of active galaxy called the Seyfert galaxy.
The Seyfert galaxies are named after astronomer Carl K. Seyfert who, in 1943, published a paper on spiral galaxies with very bright emission lines.
Today we know that about 10% of all galaxies can be Seyfert galaxies. They belong to the class of “active galaxies” – galaxies that have supermassive black holes at their centers, accumulating material, which releases large amounts of radiation.
The active nuclei of Seyfert galaxies are brightest when observed in light outside the visible spectrum.
As detailed by NASA, the largest galaxy in this pair is a Seyfert Type II galaxy, meaning it is a very bright source of infrared and visible light.
Hubble Telescope captures ‘peculiar’ image in space
The image uses data collected during Hubble observations designed to study the role of dust in shaping the energy distributions of low-mass disk galaxies.
Hubble observations observed six pairs of galaxies where one was in front of the other.
Also according to the information, as IC 4271 is a Type II Seyfert galaxy, the visible and infrared wavelengths of light dominate the image.
The colors in this image are mostly visible light, while violet represents ultraviolet light and red represents near-infrared light. Check out:
