New investigations are proving that the evolution of galaxies is a complex and continuous process, and one that does not conclude once a galaxy reaches a certain mass or size. The phenomenon continues over billions of years, but the way in which the cosmic structures grow differ. Early on, when a galaxy is just formi... |

In the near future, astronomers could become able to conduct in-depth studies of supermassive stars that may have existed at the fringes of the early Universe. These objects may have been the progenitors of what would become the first supermassive black holes ever to exist. Instruments such as the NASA James Webb Spa... |

Our understanding of how black holes work from a physics perspective holds that these objects should be capable of accelerating particles at much higher energies than equipment built here on Earth ever could. Now, investigators are looking into methods of making this a reality. The international collaboration of rese... |

According to a new scientific study, it would appear that the first black holes to develop in the early Universe – in the central regions of young galaxies – were even more difficult to spot than their more modern counterparts. They were obscured by clouds of cosmic dust and hydrogen gas. For many years, ... |

A group of scientists proposes that the origin of a hybrid gamma-ray burst they observed some time ago may have been a white hole. There is no other way to explain why the event unfolded with the intensity and duration it did, they add.In order to understand why the team made this proposition, we must first look at G... |

A study of a very distant quasar has finally enabled astronomers to peer back into what experts refer to as the “Dark Ages” of the Universe, a time shortly after the Big Bang when light was scarce. The fact that light was not being produced in large amounts means that there are no residual radiation for o... |
