Astronomers Use NASA’s X-Ray Telescopes to Reveal Magnetic Field “Bones” of Hand-Shaped Nebula
The National Aeronautics and Space Administration (NASA) recently shared a breathtaking image of an energy and particle-filled nebula formed by the remnants of a pulsar, which resembled a human hand. The image, captured by NASA’s Chandra X-ray Observatory, left people in awe of its resemblance to a hand.
The caption accompanying the Instagram post explained that the hand-shaped structure was created by a pulsar’s explosive aftermath, with the blast wave from the star’s explosion moving at an incredible speed of nearly 9 million miles per hour over a span of 14 years.
Building on this discovery, astronomers have now used two of NASA’s X-ray space telescopes to delve deeper into the anatomy of this mesmerizing nebula. By combining the imaging abilities of these telescopes, they were able to unveil the magnetic field “bones” that form the hand-shaped structure.
According to a report by NASA, the Imaging X-ray Polarimetry Explorer (IXPE), the newest X-ray telescope, observed the nebula known as MSH 15-52 for approximately 17 days. The data collected by IXPE provided researchers with the first map of the magnetic field present in the hand-shaped nebula.
Roger Romani, the lead scientist from Stanford University, explained that the charged particles responsible for the X-rays travel along the magnetic field lines, similar to how bones form the basic structure of a human hand. The observation of the magnetic field has provided valuable insights into the shape and dynamics of the nebula.
Notably, the degree of polarization of X-rays in MSH 15-52 exceeded the maximum predicted level as evidenced by IXPE’s data. This indicates the presence of a highly consistent and straight magnetic field in various sections of the pulsar wind nebula, suggesting minimal turbulence in these areas.
Josephine Wong, a co-author of the study from Stanford, compared the utilization of X-rays in this research to their medical use as a diagnostic tool for humans. She suggested that X-rays can reveal hidden information that would otherwise remain concealed.
Another intriguing characteristic observed in MSH 15-52 is a bright X-ray jet that extends from the pulsar to the “wrist” area of the hand-shaped structure. NASA noted that at the start of the jet, the polarization is low due to the presence of turbulent regions with complex, tangled magnetic fields. However, as the jet progresses, the magnetic field lines straighten out, leading to an increase in polarization.
These findings indicate that particles within the nebula are drawn towards regions where the magnetic field is more uniform, such as the wrist and fingers, after receiving an energy boost in the turbulent regions close to the pulsar.
The revelations provided by the two X-ray telescopes highlight the significant contributions of NASA’s astrophysical missions in expanding our understanding of the universe. The detailed analysis of this hand-shaped nebula opens up new avenues for studying the complex interplay between magnetic fields and high-energy particles in celestial objects.
As astronomers continue to uncover the mysteries of the cosmos, the magnetic “bones” of the hand-shaped nebula serve as a reminder of the extraordinary beauty and intricate dynamics present in our vast universe.
