If a star has a mass of more than 0.08 solar masses (one solar mass is equivalent to the mass of our sun), nuclear reactions begin, and nuclear reactions cement the body's status as a star.

A star dies . When a star runs out of hydrogen fuel for nuclear fusion, its core begins to collapse. It enters the final stage of its life. At that point, the outer layers of the star expand and ...

The life cycle for a particular star depends on its size. The diagram shows the life cycles of stars that are: about the same size as the Sun; far greater than the Sun in size. All stars begin ...

Eventually, a main sequence star burns through the hydrogen in its core, reaching the end of its life cycle. At this point, it leaves the main sequence. Stars smaller than a quarter the mass of ...

For the first time, astronomers have imaged a star located outside the Milky Way galaxy. The subject, WOH G64, is a red supergiant situated roughly 160,000 light-years away in the Large Magellanic ...

Now we know the brightness and location on the two-dimensional sky for 1.7 billion stars, writes Don Lincoln. It’s hard to overstate the impact that this cornucopia of data will have for the ...

Astronomers have captured the first close-up image of a star beyond our galaxy, taken during a dramatic moment near the end of the star’s life. In it, the “behemoth” star appears to puff out ...

Throughout the series, we'll meld basic physics with the latest research in astronomy, discussing everything from black holes and dark energy to dark matter and the life cycle of a star.
