Discovery Of Most Recent Supernova In Our Galaxy
The most recent supernova in our Galaxy has been discovered by tracking the rapid expansion of its remains. This result, using NASA's Chandra X-ray Observatory and NRAO's Very Large Array, has implications for understanding how often supernovas explode in the Milky Way galaxy.
The last time anyone saw a supernova explosion in the Milky Way was in 1980, almost 330 years ago.
This supernova explosion (G1.9+0.3) occurred about 140 years ago. But it was not detected so far because it occured in a dense region of gas and dust. But the expanding gas cloud shines brightly in X- Rays and radio waves making it detectable through X- Ray and Radio telescopes.
