Astronomers uncover how massive stars form by tracking interstellar ammonia. Using the U.S. National Science Foundation ...

With an assist from the NEID spectrograph, a team of astronomers have confirmed the existence of exoplanet Gaia-4b—one of the ...

Heavier elements formed later in high-mass stars." In the Milky Way, molecular clouds that birth stars have a wiry, or "filamentary," structure that breaks apart to form a molecular cloud core, ...

Low-mass stars turn into giant stars at the end of their lives, and high-mass stars become supergiants or even hypergiants. At the same time, the brightest stars have the shortest lifespans.

For low- to medium-mass stars like the sun, ... There is another kind of star explosion called—unsurprisingly—a Type II supernova, which is triggered when a high-mass star dies.

There are many more low-mass stars than high-mass stars because star formation favors objects of lower mass and stars with more mass have shorter lifespans, said study coauthor Roman Gerasimov, a ...
