There aren't any monstrous galaxies left in the modern Universe, but astronomers believe that these young galaxies matured
into giant elliptical galaxies which are seen in the modern Universe.
This is the first direct observational evidence that at least some of the earliest so - called «dead» galaxies — where star formation stopped — somehow evolve from a Milky Way - shaped disk
into the giant elliptical galaxies we see today.
Not exact matches
Most clusters in the universe today are dominated by
giant elliptical galaxies in which the dust and gas has already been formed
into stars.
Some of the dust inside Centaurus A maps out what appears to be a barred spiral
galaxy, which has recently merged with its
giant elliptical host and is feeding gas
into the host's central hole to produce bi-polar jets that are bright in radio wavelengths (more from APOD and ESA).
