On February 27, the National Aeronautics and Space Administration (NASA) space agency shared incredible images of a stars explosion (Supernova) taken by its Hubble telescope.

So what happens when a star dies? All stars eventually run out of hydrogen gas. Once no fuel is left, the star collapses, and the outer layers explode as a 'supernova'. NASA recently shared one such phenomenon. They always wow the internet by posting incredible pictures of stars and galaxies on their official Twitter handle @NASAHubble.

The third picture is of a Crab Nebula. "This is the mess that is left when a star explodes. The Crab Nebula, the result of a supernova seen in 1054 AD, is filled with mysterious filaments," NASA explained. The fourth and last image is that of a supernova 2,400 light years away that looks like an orange ribbon. The photo is part of the Cygnus supernova blast wave, which is found in "the northern constellation of Cygnus (the Swan), where it covers an area 36 times larger than the full Moon," NASA said.

According to NASA, supernova explosions happen when there is a change in the core or centre of a star. The supernova remnants consist of material from the exploded star as well as any interstellar material it captures in its path.

Social media users are in awe of these stunning pictures.

Replying to NASA's post, a Twitter user, @HeiKo51112349 wrote: "Though stars may die, they leave behind, A legacy that we can view, a cosmic tale for all mankind, Of beauty, power, and the new."

Commenting on a picture, another Twitterati named @Mercy said: "This must be the Timeline between parallel universe."
