Dark matter stars have been proposed to exist for a long time now, but thus far investigators have not been able to discover dark matter, let alone a star made entirely out of the stuff. In a new study, experts propose that finding these cosmic structures is within our current technological capabilities.
What the te... |

According to the conclusions of a new scientific study, it would appear that stable equilibrium is the operative concept when it comes to the formation of new stars. Even if they form from immense hydrogen clouds, they tend to shrink until they reach a balance.
This is also true for massive stars, of the type that ... |

Astronomers recently came to an agreement that Eta Carinae, one of the largest stars in the known Universe, might explode without forewarning at any time. This is important news for us because the object is just some 7,500 light-years away from Earth, practically in our backyard.In all fairness, the massive star may ... |

At one point in time, whenever physicists spoke of cold fusion, they were given the silence treatment, or were looked at in disbelief. But those days seem to have disappeared, according to ideas being circulated at the 239th National Meeting of the American Chemical Society (ACS). The meeting is being held at the Mos... |

For more than two decades, astrophysicists have been puzzled by a very strange cosmic event. Every time a new, massive star is born – of the class whose members have several hundred times the mass of our Sun – it continues to gather material from the remnants of the clouds that collapsed to form it. This ... |

One of the most important goals in physics today is achieving nuclear fusion, the type of reaction that powers up the Sun. Rather than splitting atoms, this nuclear reaction actually merges the nuclei of deuterium and tritium atoms, producing helium and vast amounts of energy, However, designing a working nuclear fus... |

Astronomers term massive stars all of the celestial bodies that have a mass several times that of our Sun. These massive spheres of fire are capable of many things when they finally reach the end of their burning cycle, such as transforming into neutron stars, or even black holes. But, almost inevitably, when they ru... |

A few years ago, if someone would have told a scientist that humans will end up producing materials that are more dense than the core of the Sun, they wouldn't have believed it. Still, this is true now. Researchers at the University of Gothenburg are working on creating ultra-dense deuterium (more commonly known... |

That's like having an 80 year old woman giving birth to a baby.
