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'.
