After 25 years in use, the Hubble Space Telescope has been doing amazing work and it has provided many amazing images to astronomers. It has always come up with stunning imagery almost everywhere it trained its focus. The most recent capture of Hubble is a blue bubble surrounding a Wolf–Rayet star called WR 31a, presently 30,000 light years away.

For a ‘broken’ telescope, the Hubble still provides the world beautiful imagery almost every week. NASA carried out all the servicing on the telescope when there was a space shuttle program, it’s easy skip from min that the European Space Agency and NASA are partners in the telescope and this was the reason that the ESA reported on the image, though on the NASA website.

The ESA explained, “The distinctive blue bubble appearing to encircle WR 31a is Wolf–Rayet nebula — interstellar cloud of dust, hydrogen, helium and other gases. Created when speedy stellar winds interact with outer layers of hydrogen ejected by Wolf–Rayet stars, these nebulae are frequently ring-shaped or spherical”.

It is estimated that the bubble is nearly 20,000 years old and has been extending at a fast rate at a clip of nearly 136,700 miles an hour. The star it belongs to, has a cosmological remaining life of nearly 250,000 years and even astronomers explain it saying that it is a mere ‘blink of an eye’ in terms of astronomy.

The 20,000-year-old nebula is actually stunning in its outlook, knowing the vast emission lines of helium, nitrogen and carbon, are incredibly hot and massive in size.

WR stars have size roughly 20 times the Sun. They are usually 5 to 30 times hotter and their brightness levels can surpass that of the Sun by a factor of around 30.
