NASA's Imaging X-ray Polarimetry Explorer

Recently, using NASA's Imaging X-ray Polarimetry Explorer, astronomers examined a supernova explosion that took place more than 450 years ago (IXPE).
People on Earth were able to see the Tycho explosion in 1572, and the blast's shock wave is still resonating throughout the cosmos.

Describe Tycho

Tycho is categorised as a Type Ia supernova, which happens when a white dwarf star rips apart its partner star, causing a catastrophic explosion and shooting material into space at extremely high velocities.
Tycho launched particles into space at speeds close to the speed of light and expended as much energy as the Sun would in ten billion years.
In order to learn more about how particles are driven nearby Tycho's shock wave and to examine polarised X-rays from the supernova remnant, researchers employed IXPE to disclose the magnetic field geometry.

Imaging X-ray Polarimetry Explorer: What is it?

About: NASA and the Italian Space Agency collaborated to create the IXPE Space Observatory.
The most extreme and enigmatic objects in the universe, including supernova remnants, supermassive black holes, and numerous other high-energy objects, are studied by it.
Importance: It will make it easier to study polarised X-ray emissions from supermassive black holes and neutron stars.
X-ray polarisation measurements can be used to reconstruct the origin of the light, including the geometry and internal structure of the source.

It will clarify how black holes rotate, where they were located in the past, and why pulsars flare so brightly in X-rays.
