Space scientists discover "mysterious objects" unlike anything seen before
Daily Express • • science
Key Points:
- Scientists have discovered 84 "hypersoft X-ray sources" in six galaxies, emitting unusually low-energy X-rays and intense ultraviolet radiation, a phenomenon not previously observed.
- These newly identified objects could help solve two major astrophysical mysteries: the origins of Type Ia supernovae and the cause of electron stripping from interstellar gas in some galaxies.
- Type Ia supernovae, crucial for measuring the universe's expansion, are thought to originate from white dwarf systems pulling material from companion stars, but their progenitors have remained elusive until now.
- The intense ultraviolet radiation from these hypersoft X-ray sources may explain the electron stripping process, which affects star formation rates and galaxy evolution beyond the influence of hot, massive stars.
- Researchers plan further observations to better understand these objects and confirm their impact on cosmic phenomena and galaxy life cycles.
