G1.9+0.3

G1.9+0.3 is the remnants of a massive star that exploded in a supernova, located near the center of our galaxy. It’s the youngest known supernova remnant in the Milky Way, about 110 years old. The explosion produced a shockwave that is still expanding outward at thousands of kilometers per second, heating the surrounding gas and dust, which emits X-rays and radio waves. Studying G1.9+0.3 helps scientists understand how supernovae evolve, enrich space with elements, and influence their galactic environment.
