This picture incorporates a comparatively small galaxy often called UGC 5189A, which is situated about 150 million light-years away within the constellation Leo. This galaxy was noticed by the NASA/ESA Hubble House Telescope to check a supernova explosion in 2010 often called SN 2010jl. This specific supernova is notable as a result of it was an exceptionally luminous supernova occasion. In truth, over a interval of three years, SN 2010jl launched at the very least 2.5 billion occasions extra seen power than our solar emitted over the identical timeframe throughout all wavelengths.
Even after supernovae fade to non-observable ranges, it’s nonetheless fascinating to check the environments the place they occurred. Such research can present astronomers with invaluable info: supernovae can happen for quite a lot of causes and understanding the environments wherein they happen helps enhance our understanding of the circumstances that triggered them. Observe-up research after supernovae additionally enhance our understanding of the speedy aftermath of such occasions—from their potent results on the fuel and dirt round them, to the stellar remnants they go away behind.
Hubble has noticed UGC 5189A many occasions since 2010. This picture is from information collected in three of the newest Hubble research of UGC 5189A. These research additionally examined a number of different comparatively close by galaxies that just lately hosted supernovae—”comparatively close by,” on this context, means roughly 100 million light-years away.
