Stars in other galaxies much heavier than our own - study

A new study suggests that the stars in other parts of the universe may be much heavier than the stars in our own Milky Way galaxy.

The discoveries, published in The Astrophysical Journal, upend earlier notions about the cosmos.

Space exploration has advanced greatly. In our Milky Manner galaxy, stars are ordered and dispersed in a certain way.

Scientists can determine mass from this and other advances. With mass, it's easy to grasp how stars' gravitational pull affects everything around them.

Nearly everything astronomers know about galaxies hinges on stellar mass.

Most scientists expected star mass would vary across galaxies. This variance was hard to determine, hence a universal model was used.
