Astronomers in the US believe they have figured out how stars form from clouds of gas. They say that all stars are created by the gravitational collapse of large molecular clumps, and that the rival ...

Stars are often organized using what's known as the Hertzsprung-Russell (H-R) diagram. Stars like Earth’s sun that burn hydrogen into helium are in a group called the "main-sequence." ...

Later lots of stars formed in many galaxies ... data—redshift z and the associated star formation rate ψ—in a diagram, you get a curve that is described by the equation above.

Astronomers have struggled to understand how the largest stars — up to 120 times as massive as the Sun — can form by sucking in nearby matter. The problem is that, once a star reaches about 20 solar ...

“This allows us to use the colour-magnitude diagram as a clock,” he adds ... When Terzan 5 formed its first stars 12 billion years ago, those stars grew from the same pristine material.
