Astronomers using NASA / ESA’s Hubble Space Telescope have captured an astonishing photo of the particular galaxy SDSS J225506.80 + 005839.9.

SDSS J225506.80 + 005839.9 (J2255 for short) is located in the northern constellation of Pisces.
Also known as LEDA 1180817, the galaxy is the result of an ancient cosmic fusion between two galaxies.
“J2255 is a post-starburst galaxy, which is a product of galaxies that have merged over the past billion years,” the Hubble astronomers said.
“This merger event brought gas to the center of the galaxy and created an abundance of new stars, the brightest of which are visible in the core of the remaining galaxy.”
“The visible shells and tails surrounding the galaxies are also the result of this merger event.”
“Residing far beyond our own Milky Way galaxy, it is nearly impossible to glimpse this galaxy without the assistance of Hubble, and, like thousands of similar faint and very distant galaxies, it has only been discovered and cataloged in recent years,” they added.
“Many millions of galaxies still await our discovery as we build a wonderful picture of our night sky.”
The color image of J2255 is made up of observations from Hubble’s Wide Field Camera 3 (WFC3) in the optical part of the spectrum.
Two filters – the blue filter F438W and the red filter F625W – were used to sample various wavelengths.
Color results from assigning different hues to each monochrome image associated with a single filter.
