Story summary

The study of dwarf galaxy NGC 6789, 12 million light-years away in the Local Void, found no evidence of past mergers.
Ignacio Trujillo led the research, noting 4% of NGC 6789’s stellar mass formed in the last 600 million years despite apparent fuel scarcity.
Findings suggest new stars arose from leftover gas from the galaxy’s formation or pristine gas within it, but the exact source remains unclear.
