Using the James Webb Space Telescope, astronomers have unearthed compelling evidence of a neutron star within the debris of Supernova 1987A, providing critical insights into the aftermath of the cosmos’ most spectacular explosions.
Astronomers have made a groundbreaking discovery in the quest to understand the remnants of Supernova 1987A, the most recent supernova visible to the naked eye, which occurred over three decades ago. For years, the fate of the massive star that exploded remained a mystery, with scientists unsure whether it had collapsed into a neutron star or a black hole. Recent observations made using the James Webb Space Telescope have now provided compelling evidence of a neutron star at the heart of the supernova’s remnants.
Located in a nearby dwarf galaxy, Supernova 1987A has been the subject of intense study since its explosion. The discovery was facilitated by the observation of heavy argon and sulfur atoms, stripped of their electrons, indicative of the presence of a neutron star. This finding suggests a powerful source of ultraviolet and X-ray radiation, with the neutron star’s surface temperature estimated to be around a million degrees.
The study, published in the journal Science, marks a significant achievement in solving a longstanding mystery in the field of astronomy. Professor Mike Barlow from University College London, a co-author of the study, shared his excitement over the findings. The discovery is expected to refine models of supernovae and enhance our understanding of how certain chemical elements essential for life, such as carbon, oxygen, and iron, are formed.
The James Webb Space Telescope’s capabilities in observing infrared wavelengths were instrumental in detecting the aftermath of the supernova. With the material from the explosion still expanding, scientists are optimistic about gaining further insights into the properties of the neutron star in Supernova 1987A. The international collaboration of researchers emphasizes the importance of this discovery in advancing our knowledge of stellar evolution and the processes that lead to the creation of life-sustaining elements in the universe.
