Arp 28 is located approximately 145 million light-years away in the constellation of Pegasus.
Also known as NGC 7678, LEDA 71534 and UGC 12614, the galaxy is classified as a barred spiral galaxy.
Arp 28 has a diameter of around 115,000 light-years, similar to that of our Milky Way Galaxy.
The galaxy was discovered on September 15, 1784 by the German-British astronomer William Herschel.
“Arp 28 is among the 338 galaxies presented in the Atlas of Peculiar Galaxies, which organizes peculiar galaxies according to their unusual features,” Hubble astronomers said.
“This catalogue was produced in 1966 by the American astronomer Halton Arp.”
“Arp 28 is listed together with six others in the group ‘spiral galaxies with one heavy arm’.”
The new image of Arp 28 was made from separate exposures taken in the visible and near-infrared regions of the spectrum with Hubble’s Wide Field Camera 3 (WFC3) instrument.
The color image is based on data obtained through four different filters.
The color results from assigning different hues to each monochromatic image associated with an individual filter.
