The dazzling blue bubble surrounds an incredibly hot and massive Wolf-Rayet star named WR 31 a.

Hubble Space Telescope has captured a stunning blue colored bubble in outer space. The dazzling bubble is located some 30,000 light years away from the Earth in the constellation of Carina.

The blue bubble is encircling a luminous Wolf-Rayet star named WR 31 a, a type of stars that are extremely hot and giant-sized. Wolf-Rayet stars have a mass at least 20 times that of the Sun but it appears that they are in a great hurry to shed their mass. Typically, a Wolf-Rayent star loses half of its mass in less than 100,000 years and WR 31 a star is no exception to this case. In the ending stage of its life, this star will explode into a supernova and its remnants will later be used for producing next generations of stars and planets.

Most of the brightest and massive stars in our galaxy Milky Way are Wolf-Rayet stars. Since these stars are intense in nature, they have very short life cycle – only a few hundred thousand years. It’s like a blink of an eye in cosmic terms.

The blue bubble, which is surrounding the star, is estimated to have formed around 20,000 years ago and is expanding at a rate of around 220,000 kilometers per hour. It’s actually an interstellar cloud of dust, hydrogen, helium and other gases and is created when speedy stellar winds interact with the gas ejected by Wolf-Rayet stars. These bubbles are usually spherical or ring-shaped.
