NASA's Hubble Space Telescope has clicked a picture of a stunning blue bubble in space, a star known as WR 31a wrapped in blue wonder. The photograph is possibly the most detailed picture of the star ever clicked.

The Hubble Space Telescope has always been in limelight for bringing captivating images from space like birth of a star, star death and even that of the first forecasted supernova explosion. The telescope has acted as our planet’s window to the world outside. And it has sparked interest again with the so-called ‘blue bubble’.

The blue bubble is surrounding a Wolf-Rayet star present at a distance of around some 30,000 light years from earth and has been discovered in the Carina constellation.

Astronomers informed that the bubble is probably composed of hydrogen, dust and helium, along with a number of other gases. It is an outcome of fast moving stellar winds that come in touch with the outer areas of hydrogen released by Wolf-Rayet stars. The resultant nebulae generally follow a ring or spherical shape.

As per astronomers’ estimations, the bubble came into existence roughly 20,000 years ago and has been extending at a rate of nearly 136,700 miles per hour.

The blue bubble is very beautiful, but short lived. Such stars have a life span of about 100,000 years, which is quite short if cosmic standards are considered. In a statement, NASA said that WR 31a isn’t an exception to this case.

If we compare, the star is 20 times bigger than sun. Wolf-Rayet stars are 5 - 30 times hotter and over a million times brighter as compared to Sun. The characteristics indicate that WR stars are huge, fiery and bright. But, the same stunning features are responsible for their short life span.
