Big brother of Halley’s Comet ripped apart by a dead star 
In a first, NASA witnessed a comet-like object disintegrate in a dead star's atmosphere. It was chemically similar but one lakh times more massive than Halley's Comet, prompting astronomers to nickname it as the comet's 'big brother'. Rich in elements essential for life, the object was destroyed by 'white dwarf', a star in its final stages due to fuel exhaustion.
