NASA’s Hubble space telescope has delivered mesmerizing images of a blue bubble that was identified this week. According to experts, images of this blue bubble are the most captivating and intriguing images of recent time .This blue bubble is surrounding the star WR 31a.
Astronomers from NASA and the European Space Agency (ESA) jointly managed to capture images of this fantastic Wolf-Rayet star. Scientists stated that Wolf-Rayet stars are much powerful than our own star sun. Wolf-Rayet stars are at least 20 times bigger and enormous than our own sun. These stars also have an extremely short span of life. Star WR 31 is also detected 30,000 light years from our planet earth. The mass of this star is 20 times larger than of our star sun.
The Wolf-Rayet nebula is a combination of hydrogen, dust and helium in huge proportion. Other gasses are also mixed in this combination. The blue bubble star originated approximately 20,000 year ago. NASA also declared that Wolf-Rayet nebula is enlarging at a speed of 220000 kilometers per hour.
NASA stated that “The blue bubble was identified to have emerged around 20,000 years ago. The Hubble Team also explained why the star was expanding at a speed of 220000 kilometers speed per hour. The space agency explained that the bubble is “an interstellar of dust, hydrogen, helium and many other gases.”
Star WR 31a is identified in the Carina constellation. Because both blue bubble nebula and its star has very short span of life, the Hubble telescope has captured images in the perfect time. Very soon WR 31a will be end up as a supernova.
The lifespan of this star is so shot that if we compare their lifespan with our own star sun then it would be considered just a glimpse in the cosmological calendar. Our great majestic sun is about 4 billion years old. While Rayet Stars has finished part of their mass in 100,000 years. So according to scientists, WR31a is definitely scheduled to end up a supernova death very soon. NASA further stated that the ultimate explosion will be feeding new planets, stars and will provide fuel in continuing chain of life.
