The main question in astronomy today is related to identifying the places in the Universe where life has the most chances of appearing, developing and enduring. While many experts look for such places based on one theory or the other, some are trying to determine where life could never appear. In other words, they ar... |

Billions of years ago, when the entire Universe was only a fraction of its current age, things were not set up as clearly as they are now. There should have been more concentrations of matter, and therefore more new objects being born, but was not the case. Experts now try to grapple the mystery of this.They know tha... |

Astronomers believe they may have discovered a new type of stellar event, given that they were able to identify a peculiar dust ring spinning around an old star. This is weird simply because such disks usually develop only around young, blue stars, and they disappear in time. In the case of the Sun, it was such a dis... |

One of the theories that astronomers had about how gas giants form says that the massive objects can appear around their parent stars when the cosmic fireballs are still very young. That is to say, as soon as the stars form, the planets appear, and then grow by accumulating gas. Though the idea was widely circulated... |

Astronomers have been puzzled at the way the Large Magellanic Cloud produces stars for several decades.
