Astronomers at the University of Missouri discovered nine unusual galaxies with the James Webb Space Telescope, dubbed 'platypus galaxies'.
The galaxies appear as compact point sources and lack characteristics of known quasars.
The findings were presented at the 247th American Astronomical Society meeting in Phoenix.
