UGC 3478 lies around 128 million light-years far from Earth in the constellation of Camelopardalis.
Understood as LEDA 19228, INTREF 304 or IRAS 06280 +6342, it is categorized as a Seyfert galaxy, a type of galaxy with an active galactic nucleus (AGN) at its core.
“Looking past its long spiral arms filled with stars and the dark threads of dust crossing it, your eye may be captured by the shining point at the center of UGC 3478,” the Hubble astronomers stated.
“This point is the galaxy’s nucleus, and certainly there is something unique about it: it is a growing huge great void which astronomers call an AGN.”
“Like all such active galaxies, the brightness that you see here conceals a supermassive great void at the center of the galaxy,” they included.
“A disk of gas spirals into this great void, and as the product crashes together and warms up it produces extremely strong radiation.”
“The spectrum of this radiation consists of difficult X-ray emission, which plainly mark it out from the stars in the galaxy.”
“Despite the strong brightness of the compact main area, we can still plainly see the disk of the galaxy around it, that makes the galaxy a Seyfert galaxy.”
“Many active galaxies are understood to astronomers at huge ranges from Earth, thanks to the fantastic brightness of their nuclei highlighting them beside other, dimmer galaxies.”
“At 128 million light-years from Earth, UGC 3478 is favorably neighborly to us,” the astronomers stated.
The brand-new picture of UGC 3478 is comprised of observations from Hubble’s Advanced Camera for Surveys (ACS) in the near-infrared and optical parts of the spectrum.
2 filters were utilized to sample different wavelengths. The color arises from appointing various colors to each monochromatic image connected with a private filter.
“The information utilized to make this image originates from a Hubble study of neighboring effective AGNs discovered in reasonably high-energy X-rays, like this one, which it is hoped can assist us to comprehend how the galaxies engage with the supermassive great voids at their hearts,” the scientists stated.
