Massive stars as a research area encompasses the theoretical, observational, and computational study of stars with initial masses typically ≥8–10 solar masses, focusing on their formation, internal structure, evolution, feedback, and endpoints. This field investigates radiative and mechanical feedback on the interstellar medium, nucleosynthesis and chemical enrichment, stellar winds, rotation, binarity, and magnetic fields, as well as the progenitors of core-collapse supernovae, gamma-ray bursts, and compact remnants. Research integrates multiwavelength observations, stellar evolution and hydrodynamic simulations, and population synthesis to constrain mass loss, convection, mixing processes, and the role of massive stars in galaxy evolution and cosmology.
The launch of NASA's James Webb Space Telescope (JWST) in 2021 pushed the horizon of seeing the early universe, unveiling cosmic events just a few hundred million years after the Big Bang. Among the most striking discoveries ...

For decades, astronomers were only able to study the universe's very first stars using theoretical models. Now, observations from the James Webb Space Telescope (JWST) have revealed what may be the most compelling evidence ...
Astronomers from the Chinese Academy of Sciences (CAS) have employed the Lijiang 2.4-m telescope to perform optical photometric and spectroscopic observations of a core-collapse Type IIP supernova designated SN 2024abfl. ...
An international team led by Monash University has uncovered evidence of a rare form of exploding star, helping to shed light on one of the most cataclysmic events in the universe. At the end of their lives, most massive ...

Using the James Webb Space Telescope (JWST), astronomers have discovered a new red galaxy at a redshift of approximately 11.45. The newfound galaxy, which received designation EGS-z11-R0, turns out to be the most distant ...
Visible to the naked eye in the constellation Cassiopeia, the star γ Cas has puzzled astrophysicists for half a century. It emits X-rays of an intensity and temperature incompatible with what one would expect from an ordinary ...
