NASA has identified a mysterious red object, named CWISE J1249, moving at an incredible speed of over 1 million miles per hour through the Milky Way. This fast-moving sphere exhibits properties that challenge conventional understanding of stars and planets—it behaves like a rogue planet yet resembles a failed star, with an anomalous composition and minimal metal content.
Detected by NASA’s Wide-field Infrared Survey Explorer (WISE), CWISE J1249 was initially noted as a bright spot, but further analysis revealed its unique characteristics. Unlike typical celestial objects, it lacks the brightness of a star and has an unusual infrared signature. Its high speed is extraordinary, even compared to runaway stars, raising questions about its origin.
Two primary theories regarding its origin are being explored: it could be a fragment of a white dwarf supernova or a failed star/expelled planet that was ejected from its system due to gravitational forces. Both theories, however, fail to fully account for all observed features of CWISE J1249.
The study of such rogue objects is vital for understanding galactic dynamics and the effects of cosmic explosions on surrounding matter. If confirmed as a supernova remnant, CWISE J1249 could provide significant insights into stellar evolution and the structure of galaxies.
