But even the mass of a brown dwarf isn't enough to overcome the Coulomb barrier and start up stellar fusion. Fusion takes so much energy that some elements, up to the atomic mass of iron, are only ...

For decades, astronomers have wondered what the very first stars in the universe were like. These stars formed new chemical ...

Astronomers have glimpsed the inner structure of a dying star in a rare kind of cosmic explosion called an "extremely stripped supernova." ...

Two factors result in so many different types of stars: the size of the clouds they are born from and what kinds of elements they contain.

New research has found that heavier elements from iron to uranium may have been formed through eruptions on a rare type of star called a magnetar. Magnetars, which have been around since before ...

The scientists searched for evidence of these particularly ancient stars in the Large Magellanic Cloud and catalogued ten of them, first with the European Space Agency’s Gaia satellite and then with ...

Astronomers have seen a lot of stars explode, but one unusual stellar death is forcing them to rethink what they thought they knew. In 2021, a star about 2.

Astronomers studying how elements heavier than iron were produced in the early Milky Way have identified a distinct series of epochs of galaxy-wide chemical formation. This evolutionary timeline ...

These stars formed new chemical elements, which enriched the universe and allowed the next generations of stars to form the first planets.
