This release features a composite image of a pulsar wind nebula, which strongly resembles a ghostly purple hand with sparkling fingertips. A pulsar is a highly magnetized collapsed star that rotates and creates jets of matter flowing away from its poles. These jets, along with intense winds of particles, form pulsar wind nebulae. Here, the pulsar wind nebula known as MSH 15-52 resembles a hazy purple cloud set against a black, starry backdrop. Both NASA's Chandra X-ray Observatory and the Imaging X-ray Polarimetry Explorer (IXPE) have observed MSH 15-52. Their observations revealed that the shape of this pulsar wind nebula strongly resembles a human hand, including five fingers, a palm and wrist. The bright white spot near the base of the palm is the pulsar itself. The three longest fingertips of the hand-shape point toward our upper right, or 1:00 on a clock face. There, a small, mottled, orange and yellow cloud appears to sparkle or glow like embers. This orange cloud is part of the remains of the supernova explosion that created the pulsar. The backdrop of stars was captured in infrared light.

View of MSH 15-52

In 2001, NASA’s Chandra X-ray Observatory first observed the pulsar PSR B1509-58 and revealed that its pulsar wind nebula (referred to as MSH 15-52) resembles a human hand. Now Chandra’s data of MSH 15-52 have been combined with data from NASA’s newest X-ray telescope, the Imaging X-ray Polarimetry Explorer (IXPE) to unveil the magnetic field “bones” of this remarkable structure.
