In 2009, NASA’s Chandra X-ray Observatory unveiled a stunning image of a pulsar and its surrounding nebula, intriguingly shaped like a human hand. This cosmic spectacle has since drawn consistent attention from astronomers who continue to explore its mysteries.
Recent collaboration between data from the Australia Telescope Compact Array (ATCA) and Chandra’s X-ray findings offers new insights into this fascinating exploded star. At the heart of this image is pulsar B1509-58, a rapidly spinning neutron star no larger than 12 miles across. Despite its small size, it generates an expansive nebula called MSH 15-52, stretching over 150 light-years—about 900 trillion miles. This nebula’s form, with its palm and fingers pointing upward, is created by energetic particles emitted from the pulsar.
The pulsar was born from the collapse of a massive star, which imploded after depleting its nuclear fuel. This catastrophic event led to a supernova explosion that dispersed the star’s outer layers into space. Pulsar B1509-58 spins nearly seven times each second and possesses a magnetic field 15 trillion times stronger than Earth’s. These factors make it an incredible source of electromagnetic energy, driving a wind of particles that shapes the surrounding nebula.
The latest composite image merges ATCA’s radio data—shown in red—with Chandra’s X-ray data in blue, orange, and yellow. Overlapping areas reveal a striking contrast, with purple indicating regions rich in both data types. Additional optical images detail the hydrogen gas surrounding the pulsar and remnants of the supernova, known as RCW 89.
The new radio data expose intricate filaments aligned with the magnetic field of the nebula. These filaments could be the result of the pulsar’s particle wind colliding with the remnants of the supernova. Comparisons of radio and X-ray data show differences in light sources, indicating that some X-ray features are missing in radio waves, hinting at energetic particles escaping a shock wave near the pulsar.
Interestingly, the structure of RCW 89 diverges from typical young supernova remnants. The patchy radio emissions suggest it’s interacting with dense clouds of hydrogen nearby. One puzzling finding is the sharp edge of X-ray emission that indicates the supernova’s blast wave, which usually also emits strong radio signals. This lack of signal in the radio data raises intriguing questions.
Overall, PLS 15–52 and RCW 89 have unique qualities, but many aspects of their formation and evolution remain unclear. Future research aims to deepen our understanding of the interactions between the pulsar and its environment.
