Just as people of the same age can vary greatly in appearance and shape, so do collections of stars or stellar aggregates. New observations from the NASA/ESA Hubble Space Telescope suggest that ...

Astronomers have confirmed that one of the fastest-changing stars ever observed has entered a new stage of its evolution, offering a rare opportunity to watch a star's life unfold on human timescales.

A new study published in The Astrophysical Journal, led by Assistant Professor of Astronomy Rana Ezzeddine and UF alumnus Jeremy Kowkabany, with collaborators, reports the discovery of a star that ...

What can binary stars comprised of two different types of stars teach astronomers about stellar evolution? This is what a recent study published in The Astrophysical Journal hopes to address as a team ...

Astronomers understand the basics of star formation. It starts in giant molecular clouds when an event - perhaps a nearby supernova or a collision with another cloud - triggers a high-density region ...

The chemical evolution of stars within the Milky Way traces the complex interplay between nucleosynthesis, gas inflows and outflows, and dynamical processes that shape the Galaxy’s structure over ...

Massive stars, typically defined as those exceeding eight solar masses, undergo a rapid and complex lifecycle driven by successive nuclear fusion stages. From hydrogen burning on the main sequence ...

A new study suggests that subtle changes in the behavior of neutrinos could determine whether some massive stars explode as supernovas or collapse into black holes, according to research published in ...
