Scientists have made a groundbreaking observation, capturing for the first time the early stages of a supernova - the cataclysmic collapse of a star that is one of the most awe-inspiring cosmic events. This extraordinary event was witnessed by researchers using the European Southern Observatory's Very Large Telescope (VLT) in Chile.
The supernova, which was detected on April 10, 2024, involved a massive star roughly 15 times larger than our sun residing about 22 million light-years from Earth in the direction of the constellation Hydra. Given that a light-year is the distance light travels in a year - approximately 9.5 trillion kilometers - this makes for an incredibly distant event.
What was remarkable about this observation is that it captured the supernova at its very early stages, just 26 hours after detection and 29 hours after material from inside the star broke through its surface. This allowed researchers to observe the explosion as it pushed outwards violently from the stellar core, distorting the star's shape into a vertical-standing olive-like form.
Notably, this event defied our previous understanding of supernovae explosions, which typically follow a spherical pattern. Instead, the explosion ripped through opposite sides of the star, offering researchers a rare glimpse into the complexities of these cosmic events.
The discovery sheds light on stellar evolution and the physical processes that lead to these spectacular explosions. According to astrophysicist Yi Yang, the geometry of a supernova provides fundamental information on how stars are born, live, and die. The study published in Science Advances offers new insights into the mechanisms behind massive star supernovae.
One such massive star was the red supergiant at the center of our galaxy NGC 3621, which had a diameter 600 times greater than that of our sun. When it exploded, some of its mass was expelled into space, while the remainder is believed to have become a neutron star - a highly compact stellar remnant.
This remarkable discovery highlights the importance of cutting-edge telescopes like VLT in unraveling the mysteries of the universe. By gaining a deeper understanding of these events, researchers can refine their models and shed more light on the cosmos.
