SNR G156.2+5.7 is a large, shell-type supernova remnant (SNR) located in the Milky Way Galaxy. With an apparent diameter of about 3° across the sky, its angular size is notably large. For context, the full Moon appears roughly 0.5° across, making G156.2+5.7 about six times wider in apparent size. This substantial angular extent reflects both its relative proximity and the long period over which the remnant’s shock waves have expanded and diffused into the surrounding interstellar medium (ISM).
Situated approximately 3,000 light-years from Earth in the constellation Perseus, G156.2+5.7 is thought to have originated from the supernova explosion of a massive star tens of thousands of years ago. In the aftermath, the stellar debris has formed a roughly spherical shell that continues to expand and evolve. As the shock wave plows into the ISM, it compresses and heats the interstellar gas and dust, producing emission that is particularly bright at the remnant’s outer edges.
Observations of G156.2+5.7 span multiple wavelengths, but the most comprehensive data have come from radio and X-ray studies. Radio surveys helped to discover its shell-type structure, revealing the distribution of relativistic electrons and magnetic fields. Subsequent X-ray observations using telescopes like ROSAT and XMM-Newton have provided deeper insights into the hot plasma within the remnant, allowing astronomers to map temperature variations, estimate the shock velocities, and probe the chemical abundances of the ejected material. Such analyses help researchers understand the energy released during the supernova event and the mass and nature of the progenitor star.
While G156.2+5.7 may not be as famous as remnants like the Crab Nebula or Cassiopeia A, it nonetheless plays an important role in our broader understanding of stellar and galactic evolution. Supernova remnants act as chemical “factories” and distributors, seeding the galaxy with heavy elements that become the raw materials for new stars, planetary systems, and potentially life. Investigating objects like G156.2+5.7 helps us piece together how supernova explosions shape the structure, composition, and future of the Milky Way.
