NASA recently captured a jaw-dropping image of a sphere which is called Bubble Nebula, adding another masterpiece to the stunning Hubble space telescope images. The Bubble Nebula was developed around four million years ago and the star at the core of Bubble Nebula is expected to explode as a supernova in almost 10-20 million years.
The Bubble Nebula is far away from Earth, which is situated at a distant level of around 7,100 light-years from Earth, enveloped in a simmering star which is almost 45 times more colossal and immense as compared to the Sun, which is quite interesting.

Additionally, gas on the star blazes to a greater level that it escapes far away into space as a stellar breeze at approximately four million miles per hour (6.4 million kph). These gases blazes to a different temperature that ultimately emits several vibrant colourways including blue for Oxygen, green for Hydrogen, and red for Nitrogen.
The outflow of stellar winds then drifts the cold and forms the outer edge of the bubble, in front of the gas which is quite reminiscent of snowplows accumulating snow in front of it as it exceeds. As its shell amplifies, it intersects along with the dense regions of cold gas on the single side of the bubble.
