Trillion Atomic Bomb Explosions every second for millions of years

Massive Galaxy Exploded Every Second for Millions of Years - Its ability
to produce new stars was completely hindered - Softpedia
"An international group of researchers has recently determined that one
of the earliest galaxies in the known Universe has had its star-forming
abilities regulated by powerful, repeated blasts. The celestial
structure was observed by astronomers as it looked some 3 billion years
after the Big Bang, a time when the Universe was only a quarter of its
present age. The finding sheds new light on how galaxies go about
regulating their own growth process, the investigators say. The team
that made the findings was led by researchers at the Durham University
Department of Physics.

The explosions that plagued the observed galaxy, called SMM J1237+6203,
were at least several trillion times more powerful than any atomic
bomb’s, and they apparently took place once every second for millions of
years. Eventually, the entire amount of gas that the structure would
have otherwise used for stellar formation was dispersed. The main role
played by the explosions was to help hydrogen escape the dramatic
gravitational pull that the central regions of the galaxy – most likely
containing a black hole – exerted on it. The violent events were
therefore found to be guilty of hindering the emergence of blue stars in
this particular corner of the Universe. "
