Astronomers discovered a huge supernova remains in the big Magalanic Cloud

The Astronomers International Team has employed various satellites and telescopes for the performance of a supernova residue known as SNR J0450.4-7050. The results that scientists got after an observation campaign published on June 18, 2025, on the preprint server Arxiv, gained new insights into the properties of this residue, and saw that it is much larger than the idea in the past. Supernova residue (SNR) is expanded to the structures resulting from the explosion of a supernova. It usually lasts for several hundred thousand years, when it spreads to the intersteller medium.

As Study By NASA, observation by scientists indicates that the explosion in the SNR expands the eviction of the material and the other intersteler the material is washed away by the passage of shockwave from the explosion star. SNR studies beyond Milky Way are important for understanding the response in various evolutionary stages and gaining valuable insights into local ISMs. Big Magalanic clouds What is the galaxy that its SNR population has been deepened.

Importance of studying supernova remains beyond Milky Way

Recent observations suggest that SNR J0450.4-7050, LMC has a large supernova residue, with a physical dimensions of 244 light years to 332, is estimated to have a residue of about 45,000 years. Scientists named it Veliki, which means large in Serbian. It also shows complex filamentary data with various internal and external shell structures.

Veliki Search: A large, old residue in large magalnic clouds

Zachri J. A group of astronomers led by Smeton decided to closely observe the SNR J0450.4 – 7050 by the Australian square kilometer array Pathfinder and Markat Radio Telescope. SNR showed a high radial surface glow with one of the lowest average radio spectral indices with similar remains.

Unusual radio properties suggest that Veliki is a completely radiated SNR

These unusual features, according to scientists, predict that Veliki is mainly a radiated SNR with a high shock compression ratio. It tells about non-themeal spectrum and high surface glow and emissions. Further comments of the surrounding environment are required to confirm the hypothesis with an understanding of the nature of the remains better.
