Astronomers know that massive, young, blue stars are formed from equally large gas clouds, where high temperatures and chemical concentrations are just right for this to happen. However, until now, they have only observed such formations after they already took shape. In a new sky survey, a team of experts has discov... |

The worst place where a star could grow is in the vicinity of a supermassive black hole, as powerful gravitational fields exerted by the latter prevent the clouds of gas to condense into objects such as our Sun. However, astronomers have recently discovered that young stars do form near the center of our galaxy, insi... |

If you think our Sun is a big star, you've seen nothing! Behemoths as large as 120 solar masses lie all around the universe. Theory predicts that stars cannot grow larger than 150 times the mass of the Sun, either that or something drastic must happen, as stellar evolution models cannot explain such objects. Two... |

I calmly turned off the TV-set and went to work, searching the Internet for information regarding the elusive black hol... |

The newly discovered pre-main sequence young star HH211, located in the Perseus constellation at a distance of about 1,000 light years from Earth, represents the first solid evidence that stars dispose of angular momentum not only by emitting large gas jets from its poles and shedding part of its upper layers, but a... |
