NASA shares incredible images of Bubble Nebula

April 21 is the 26th birthday of the Hubble Space Telescope. To commemorate this important day, NASA announced the stunning images of a Bubble Nebula recorded by Hubble.

Bubble Nebula is a large star and has a very high temperature, it produces gas and dust that is blown into space by strong winds. These materials form spherical layers that surround the star and it always moves like a giant bubble.

NASA's astronaut John Grunsfeld said: "Hubble is 26 years old with the mission of exploring our solar system , we celebrated this special day with an impressive image of a young star. The vivid images of Bubble Nebula remind us of the importance of Hubble, this telescope helps us to observe the universe in the front row. "

NASA said this Bubble Nebula is about 45 times larger than our Sun. The gas layer on this star has a very high temperature, making the wind speed reach 6.5 million km / h. It rolls the layers of cold air around and creates a giant bubble outside the star.

Although the first person to discover the nebula's existence was astronomer William Herschel in 1787. But the Hubble glass shows us the first high-definition image of this nebula.

The blue colors you see in the main picture are oxygen, green is hydrogen and red is nitrogen.
