"Dual-Faced Dead White Dwarf Star Baffles Scientists"

Astronomers have discovered a unique white dwarf star named Janus, which has two distinct sides—one composed of hydrogen and the other of helium. This first-of-its-kind finding challenges the typical composition of white dwarfs and raises questions about the star's evolution. The researchers speculate that Janus may be undergoing a rare form of evolution, transitioning from a hydrogen-dominated surface to a helium-dominated one. They also suggest that asymmetric magnetic fields or shifting atmospheric pressures could be responsible for the star's dual-faced nature. Further observations and studies are planned to better understand this peculiar white dwarf.
