US EditionAstronomers Combine X-Ray and Radio Data to Map Pulsar 'Hand' Nebula
The composite image reveals filaments aligned with magnetic fields and shows the pulsar B1509-58 spins seven times per second with a magnetic field 15 trillion times Earth's strength.
- In 2009, a striking image depicting pulsar B1509-58 along with its hand-shaped surrounding nebula was unveiled by NASA’s Chandra X-ray Observatory.
- This pulsar originated when a large star exhausted its nuclear fuel and its core collapsed, triggering a supernova that expelled the star’s outer layers into space as debris.
- Recent observations combining radio measurements from ATCA with X-ray images from Chandra reveal intricate filaments aligned with the nebula’s magnetic field and show that the morphology of RCW 89 contrasts with that of common young supernova remnants.
- Researchers observed that the pulsar completes nearly seven rotations each second and possesses an extremely intense magnetic field, estimated to be around 15 trillion times more powerful than that of our planet, making B1509-58 a highly effective electromagnetic powerhouse that fuels a dynamic particle wind responsible for generating the surrounding nebula.
- Although these findings offer new perspectives on the environment surrounding the exploded star, many questions remain about how these structures develop and change over time, as well as how the pulsar wind interacts with the supernova remnants.
