Another news that baffled us in 2020 is the sudden disappearance of a STAR! It was noticed a year back that the star 75 million light-years away from the Earth faded away without a trace. The entire scientific community was confused as the theory of the ‘Death of a star‘ tells us a different story. All of you might have studied in High School that a star takes millions of years to die. When the fuel of a star finishes, it slowly increases its size to become a huge red-coloured ball, commonly known as ‘RED GIANT’. Then it sheds its layers and shrinks to a very dense ‘white dwarf’.
This star was 2.5 million times brighter than Earth’s biggest star, Sun, and scientists studied it from 2001 to 2011. The star was reaching its end and attracting many scientists to experience the grand death of a majestic star. But, nothing took off as planned.
For the first time, a star has died silently. It was a part of the ‘Kinman Dwarf Galaxy that’s in the Aquarius Constellation. Time for one more school lesson. A constellation is a group of stars that form different shapes in the sky. Cameras at NASA’s Hubble Space Telescope had captured images of the galaxy before the death of the star. Though the individual stars can’t be identified, NASA astronomers could detect the massive star in the galaxy.
In 2019, Andrew Allan, a doctoral student in astrophysics at Ireland’s Trinity College, and other researchers wanted to study a dying star and tried to focus on the distant gigantic star in Kinman Dwarf Galaxy. They were surprised to see that there was no sign of the huge spacial body.
While we are wondering where the huge star has gone, scientists have got a new, exciting topic to base their research on! 2020 is getting weird and we are learning more aspects of life. That’s evolution.
Stay happy, stay safe:)
