Just in time for Halloween, Nasa’s newest X-ray space telescope has acquired an eerie glimpse of a supernova explosion whose remnants resemble a skeletal hand in deep space, reported space.com.
Formally named MSH 15-52, the “ghostly hand” was formed when a massive star perished. A pulsar is a rapidly spinning, extremely dense stellar corpse that is the result of this terrible event, also known as a supernova explosion.
The term “pulsar wind nebula” refers to the enormous jets of charged particles and fierce wind produced by pulsars, which are revolving neutron stars with high magnetic fields. According to a Nasa statement, the pulsar PSR B1509-58 is situated close to the center of the picture, at the base of the palm of MSH 15-52. It shoots particles into space, forming a luminous shape that resembles a human hand.
Scientists examined MSH 15-52 for around 17 days using Nasa’s Imaging X-ray Polarimetry Explorer (IXPE), which launched in December 2021. The observations provided new information about the pulsar’s magnetic field and the orientation of its X-ray jets, or X-ray polarization.
Roger Romani, lead author of the study from Stanford University in California said in a statement, as reported by space.com, “The IXPE data gives us the first map of the magnetic field in the ‘hand'”.
Large areas of MSH 15–52 have exceptionally high levels of polarization, as seen by the space telescope, which suggests there is no turbulence in those pulsar wind nebula regions.
