A new X-Ray telescope has shared its first, historic glimpse of the cosmos. 😍🚀 Can you guess which Milky Way explosion it set it's eyes on? Find out here: 📷: NASA/CXC/SAO/IXPE
The Imaging X-Ray Polarimetry Explorer , a joint project between NASA and the Italian Space Agency, fixed its gaze on one of the most famous explosions in the Milky Way: Cassiopeia A.Located 11,000 light-years away, it's the expanding remnant of a star thought to have been observed exploding in the 1690s, and it's one of the most well-studied objects in the Milky Way, for good reason – it has provided some invaluable insight into supernovae.
There's a lot going on in Cassiopeia A. Before it died, the precursor star was a massive object that, as it ran out of fuel, became unstable, ejecting its outer layers to create a cloud of circumstellar material. When the supernova finally did take place, therefore, the shock wave was not entering pristine space, but a relatively dense cloud.
