Brilio.net - This shinning blue-tinted cosmic bubble floats 30,000 light-years from Earth, and will surely excite space enthusiasts.

The bubble-shaped blue structure is made of gas and dust, and was recently captured by Hubble Space Telescope. The bubble is actually a Wolf–Rayet nebula circling a star named WR 31a.

“Unfortunately, the lifecycle of a Wolf–Rayet star is only a few hundred thousand years — the blink of an eye in cosmic terms,” Hubble said in a statement.

As reported by Mashable, despite beginning the life with a mass at least 20 times that of the sun, Wolf–Rayet stars typically lose half their mass in less than 100,000 years.

Scientists think that the nebula formed about 20,000 years ago, and it’s moving along quickly outward at speed about 136,700 miles per hour.
