The NASA/ESA Hubble Space Telescope has taken a new picture of the relatively small galaxy UGC 5189A, which is found in the constellation of Leo.

UGC 5189A is located approximately 150 million light-years away in the constellation of Leo.
Also known as ECO 5363 or LEDA 27776, this galaxy was observed by Hubble to study a supernova explosion in 2010.
This particular supernova, designated SN 2010jl, was notable for its enormous brightness.
“In fact, over a period of three years, SN 2010jl released at least 2.5 billion times more visible energy alone than our Sun emitted over the same timeframe across all wavelengths,” the Hubble astronomers said.
“Even after supernovae have faded to non-observable levels, it can still be of interest to study the environments where they occurred.”
“This can provide us with valuable information: supernovae can take place for a variety of reasons, and understanding the environments in which they took place can help improve our understanding of the conditions necessary for them to be triggered.”
“Furthermore, follow-up studies after supernovae can improve our understanding of the immediate aftermath of such events, from their potent effects on the gas and dust around them, to the stellar remnants they leave behind.”
“To this end, UGC 5189A has been observed many times by Hubble since 2010.”
This new image of UGC 5189A is made up of observations from Hubble’s Wide Field Camera 3 (WFC3) in the ultraviolet and optical parts of the spectrum.
Two filters were used to sample various wavelengths. The color results from assigning different hues to each monochromatic image associated with an individual filter.
“This image is from data collected in three of the latest Hubble studies of UGC 5189A, which also examined several other relatively nearby galaxies that recently hosted supernovae — ‘relatively nearby’, in this context, meaning roughly 100 million light years away,” the astronomers said.
