Galaxies: star clustersGlobular clusters: generalIn many different galactic environments the cluster initial mass function (CIMF) is well described by a power law with index 2. This implies a linear relation between the mass of the most massive cluster ( M max ) and the number of clusters. ...
根据第四段中的“The discovery of this star provides some of the most direct evidence yet that the star experienced a disastrous eruption that caused it to lose mass before the ②寻线索 explosion. If the star were to make the eruption, it would probably have discharged its hydrogen decades ....

The Sun has a mass of 330, 000 times the Earth. The Sun is just one star in the Milky Way galaxy that contains over 300 billion stars and scientists estimate that there are over 170 billion galaxies in the universe!However, most of the universe is what we think of as empty space. ...
radiation streaming from the star is powerful enough to carry away material from the surface, causing the star to lose about 16 Earth's worth of mass every single year. Astronomers are unsure exactly how such a self-destructive star could form and how much longer it will hold itself together...
