Story summary

Nine 'platypus galaxies' were discovered by University of Missouri astronomers with the James Webb Space Telescope, challenging cosmic-evolution models.
They appear as point-like sources and lack features of known quasars.
The findings were presented at the 247th meeting of the American Astronomical Society in Phoenix.
Haojing Yan notes the galaxies may have formed quietly, not through violent mergers.
Further research is needed to understand their nature and implications for galaxy formation.
