A blue bubble shines in deep space in new Hubble photo
A blue-tinted cosmic bubble floats 30,000 light-years from Earth.
A newly-released photo taken by the Hubble Space Telescope shows a star, named WR 31a, circled by a Wolf–Rayet nebula — the bubble-shaped blue structure made of gas and dust in the image.
“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.
“Despite beginning 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.”
