Astronomers discover supernova remnants in large magellanic cloud, a satellite of Milky Way

At the centre of the image, stars gather to create a bright, dense green haze resembling candy floss. This glowing mass represents the Large Magellanic Cloud. Across the middle, around 50 small yellow crosses are scattered, some nearly overlapping. In the lower left quarter, SNR J0624-6948 (orange, higher) and SNR J0614-7251 (blue, lower) are visible.

Supernovae have long fascinated astronomers, revealing secrets about space. A new study has identified two supernova remnants in the Large Magellanic Cloud. These discoveries offer new insights into how stars explode and influence their surroundings.

New Supernova Remnants Detected
Researchers used the ESA’s XMM-Newton spacecraft to find SNR J0614-7251 and SNR J0624-6948. These remnants exist in the Large Magellanic Cloud, a satellite galaxy of the Milky Way. Scientists say this region is perfect for studying stellar explosions in detail.

Astronomers observed the remnants using three types of X-ray light. The data helped them determine the chemical makeup of the exploded stars. One remnant, SNR J0614-7251, was classified as a Type Ia supernova for the first time. This type occurs when a white dwarf star collapses in a binary system.

Understanding the Cosmic Impact
Supernovae play a key role in shaping galaxies by dispersing elements. Their shock waves heat and ionise surrounding gas, triggering new star formation. Studying these explosions helps scientists understand the universe’s matter cycle.

The discovery proves that supernovae occur outside galaxies. It also provides a rare chance to study stellar debris and their effects. With more advanced surveys, astronomers expect to find additional supernova remnants near the Magellanic Clouds.

The study has been published in Astronomy & Astrophysics.
