Old star, new trick
The Big Bang produced lots of hydrogen and helium and a smidgen of lithium. All heavier elements found on the periodic table have been produced by stars over the last 13.7 billion years. Astronomers analyze starlight to determine ...

List of most massive stars
This is a list of the most massive stars. The list is ordered by solar mass (1 solar mass = the mass of Earth's Sun).
Stellar mass is the most important attribute of a star. Combined with chemical compositions, mass determines a star’s luminosity, its physical size, and its ultimate fate. Due to their mass, most of the stars below will eventually go supernova or hypernova, and form black holes.
