Description:

SNR G296.5+10.0 is a large supernova remnant in Centaurus, formed by the explosion of a massive star thousands of years ago. Its distinctive bilateral shape and delicate oxygen-rich filaments make it a fascinating target in both scientific studies and deep-sky astrophotography.

At its center lies a rare neutron star, while the expanding shockwaves continue to accelerate high-energy particles through space.
