A team of researchers at the International Center for Relativistic Astrophysics has found evidence that suggests Sagittarius A* is not a massive black hole but is instead a mass of dark matter. In their paper published in ...
Stars form by the gravitational contraction of clouds of gas in space and can have various masses. Massive stars, together with many other stars, may form a huge star cluster (a group of more than 10,000 stars). The formation ...
