After more than 35 years, astronomers have finally discovered the neutron star left behind by Supernova 1987A using NASA's JWST telescope, shedding light on these extreme cosmic events.


Unveiling the Neutron Star from Supernova 1987A.

In 1987, a nearby star met its explosive end, creating the first supernova visible to the naked eye in 4 centuries. This cataclysmic event, known as Supernova 1987A, became one of the most intensely studied objects in space. Now, after decades of searching, astronomers have finally uncovered the cinder left behind by this stellar explosion: a neutron star.

The Explosive Birth of a Neutron Star Most supernovae occur when a large star, at least eight times the mass of the Sun, exhausts its nuclear fuel. The core collapses, triggering the outer layers to come crashing down. This collapse can result in either a black hole or a neutron star, depending on the star's mass. In the case of Supernova 1987A, a neutron star, a city-sized object packed with a couple of solar masses, was formed.

The Elusive Neutron Star Revealed Despite theoretical predictions and various observations over the years, pinpointing the neutron star from Supernova 1987A proved challenging. Clues began to emerge in recent years, with observations suggesting the presence of a neutron star, but conclusive evidence was lacking.

A Breakthrough with JWST The breakthrough came with the launch of NASA's James Webb Space Telescope (JWST). Its sharp vision and spectral sensors allowed astronomers to detect fluorescing argon and sulfur in the middle of the supernova remnant, a signature of a hot neutron star. This discovery marks a significant milestone in our understanding of these cosmic phenomena.

The discovery of the neutron star from Supernova 1987A, made possible by the advanced capabilities of JWST, opens a new chapter in the study of these extreme events. As researchers continue to unravel the mysteries of this neutron star, it serves as a testament to the power of scientific exploration and discovery in the vastness of the cosmos.
