Any thoughts what this blue point source could be? seems to be variable: ZTF26aaonmha
I went to the DR11 Early Images survey and the Single Exposures list is wild to me. I’ve never seen so many images especially in decam i band. The variability within bands seems be caused by the amount of aperture time 200 vs 280 seconds etc. The images are from several different years and I don’t see any reason to suspect by sight alone that a supernova has occurred. I do believe it is an exceptionally bright megallanic cloud type area with many star globular clusters, a star bursting area. It is my belief that black holes at the center of globular clusters actually combine dark matter which is smashed matter from Big Bang WIMPS into Hydrogen and potentially other gasses that perle into a bubble which are then ignited via sonoluminescence from the sound waves produced by the black hole. I like to think of globular clusters as Star Springs. There have been several discoveries that I believe are evidence this is occurring. The discovery that Little Red Dots in the early Universe were black holes encapsulated in Hydrogen gas but not yet stars. That Baryon Acoustic Oscillations BAO were detected at the earliest part of the Universe as well. BAO likely ignited the first stars this way via sonoluminescence. I think it is interesting that Ancient Egyptians and Australian Aboriginal people among others in the past believed the Universe was created by way of sacred songs ie; acoustic oscillations. Professor Tomonori Totani from Tokyo University recently announced the discovery of Gamma Rays from Sagittarius A black hole at the center of Milky Way was produced by WIMPS becoming Quarks. I believe those quarks then form Hydrogen. I believe this phenomenon also explains the disc of new blue stars around M31* at the center of Andromeda.
I do not believe this is the only way stars form but it’s hard not to look at a globular clusters in the large or small Megallanic Clouds and not think the stars are pouring out of it into the sea of blue stars instead of swirling around the drain. If you ever been to a fresh water spring you’ll see that despite gravity water bubbles up and out.

So I would say what you’re looking at there in that distant galaxy is a Gigantic Megallanic Cloud. Poppin!
