[2] Its chemical makeup have led astronomers to propose it was formed during the dawn of the universe when galaxies emerged in a different environment than today.

[7][8] At first astronomers thought DGSAT I to be an isolated dwarf galaxy beyond the Local Group due to its structural properties and absence of emission lines.

[3] DGSAT I's integral field spectroscopy data shows a remarkably low iron content, suggesting an early galaxy formed from a nearly pristine gas cloud, unpolluted by the supernova death of previous stars, however its magnesium levels are consistent with what astronomers expect to find in younger galaxies.

[3] This apparent chemical makeup discrepancy and DGSAT I's isolation from galaxy clusters are helping astronomers to develop new theories concerning the birth and formation of UDGs.

[3] UDGs are hard to observe due to their extremely low luminosity but there are studies being conducted using the Keck Cosmic Web Imager in an attempt to shed light on the precise relation between DGSAT I's metallicity and its possibly exotic origin.
