The years following the Big Bang were undoubtedly an exciting time in our cosmological history, with galaxies birthing hundreds or even thousands of hot new stars each year.
But despite rapid star formation being exhilarating, it’s far from sustainable.
Star Formation Secrets
Researchers have long wondered how these ancient starburst galaxies managed to conserve their gas and not burn out during the early years of their existence. One theory is that fierce winds would carry star-forming gas out to their borders, where it would either escape the galaxy or linger in the halo — preventing an overproduction of stars. The gas would slowly make its way back into the galaxy, where it would initiate a stellar resurgence at a less turbulent time. Researchers have witnessed this occurring in much closer starburst galaxies, but had yet to witness it in the distant universe.
