Astronomers have finally cracked a mystery that has puzzled scientists since the 1970s by identifying the source of strange X-rays emanating from the bright star gamma-Cas. Using advanced observations from the XRISM space mission, researchers discovered that an invisible white dwarf companion star is pulling material from gamma-Cas and heating it to extreme temperatures. This breakthrough not only resolves decades of questions but also deepens our understanding of how unusual binary star systems form and develop.
