Stellar explosions are often associated with supernova – an astronomical event that takes place during the concluding stages of a massive star’s life. But the new picture, captured by the Atacama Large Millimetre/Submillimeter Array (ALMA), located in northern Chile is giving entirely new insights into the star formation. In a first-of-its-kind attempt, a team of international scientists has captured the rare star formation event on camera, which shows the spectacular firework display in the deep space.
The extraordinary cataclysmic event occurred around 500 years ago in a celestial region known as the Orion Molecular Cloud 1 (OMC-1), positioned some 1,500 light-years from Earth. The big crash between two young stars, set off a stunning stellar flare-up, just like a massive fireworks show on the fourth of this month. Using the Atacama Large Millimetre/submillimeter Array (ALMA), an astronomer team has managed to capture the stunning view of the leftovers of the luminous celestial burst.
Earlier, we all knew that the formation of stars is a firework event, but the new image, clicked by ALMA shows that the formation of stars can really be a very unpredictable affair. In the most honest sense, the new pictures, clicked by the Atacama Large Millimetre/submillimeter Array (ALMA) have given scientists new insight into the mysterious star formation. Using the images, astronomers are now busy in examining the debris, attributable to the flare-up for getting a clear understanding on the aftermaths of the cataclysmic event where two sibling stars run into an astral nursery, in this case, it is Orion Molecular Cloud (OMC-1).
The Orion Molecular Cloud (OMC-1) is an astronomical nursery, located some 1,350 light-years away from the earth. It is a part of the similar complex as the Orion Nebula. As revealed by the researchers in the new study, the Proto-stars started forming in the region some 100,000 years ago, and following which they began accumulating masses. Some of them started getting nearer to each other because of gravity, and about 500 years ago, two of such stars bumped into one another – either just by foraging or colliding face-to-face. This collision triggered a super powerful outbreak that emitted as much energy as formed by the sun in 10 million years.
However, scientists are yet not sure if the crash was caused by head to head collision or was a graze. But they confirmed that the eruption heaved nearby protostars and hurled gas and energy into space at a speed of more than 150 kilometre or 93 meters per second. The image clearly showed the bright multicoloured materials, scattered in the space, which resembles firework show, moving rapidly outwards in all directions.
The paper, titled “The ALMA View of the OMC1 Explosion in Orion” and published in the Astrophysical Journal contained the complete details of the cataclysmic explosion and the impacts of it on neighbouring proto-stars. The study was led by John Bally from the University of Colorado.
