NASA’s Photo of the Day shows two different supernova remnants glowing in the heart of the galaxy.
According to RCO News Agency, After the star explodes, a huge fireball of hot gas shoots out in all directions. When this gas hits the interstellar medium, it becomes so hot that it glows.
According to NASA, Two different remnants of the supernova can be seen in a photo taken at the Oukaïmeden Observatory in Morocco.
The blue, football-shaped nebula in the upper left of the image is called SNR G179.0+02.6, which appears to be smaller. This supernova exploded about 50,000 years ago at a distance of 11,000 light years from Earth. Although this supernova is mostly composed of hydrogen gas, blue light is emitted from a small amount of oxygen.
The apparently larger supernova remnant in the lower right of the image is the Spaghetti Nebula, also known as Simeis 147 and sh2-240. This supernova, which is only about 3,000 light years away from Earth, exploded about 40,000 years ago.
Although the size of these two supernova remnants looks different, they are not only about the same age, but also about the same size.
