However, every now and then a galaxy will display a burst of newly-formed stars that shine brighter than the rest. A collision between 2 large galaxies is usually the cause of such starburst phases, where the cold gas residing in the giant molecular clouds becomes the fuel for sustaining such high rates of star formation.
The question astronomers have been asking is whether such starbursts in the early universe were the result of having an overa...
