Scientists release a picture of a gas cloud from an exploding star

On Monday, the European Southern Observatory published an image of colorful clouds of gas that were caused by the explosion of a massive star long ago.

The clouds in our Milky Way are located about 800 light-years from Earth. A light year is the distance light travels in a year, 9.5 trillion km. Scientists estimate that the star was at least eight times the mass of the Sun.

The colorful cloud is about 600 times the size of our solar system.

The picture shows pink and orange strings cloud structures. Threads are like very fine threads like silk or cobwebs.

The cloud arose from the explosion of the star, which has been dubbed a supernova.

In a supernova, a large star collapses onto its surface essence or the center. The pressure and temperature in the nucleus become so high that atoms of heavy elements are formed, and huge amounts of energy are released in a massive explosion. Supernovas can also produce very heavy elements such as iron, gold, or uranium.

NASA’s Chandra X-ray Observatory has captured many stunning images of cosmic phenomena over its two decades of operations, but perhaps the most famous is the remnant of the Cassiopeia A supernova.

Bruno Leibundgut is an astronomer associated with the European Southern Observatory (ESO). He explained that the denser regions of supernova matter hit the surrounding gas and created some of the filaments seen in the image.

He said, “Most of the material that shines because of excited hydrogen atoms. The beauty of images like these is that we can directly see the material inside the star.”

The image shows the cloud, called the nebula, 11,000 years after the eruption.

The remainder of the supernova is small, extremely dense Rotation An object called a pulsar. The pulsar rotates about 10 times per second.

The cloud image is a combination of several images taken by the VLT Survey Telescope in Chile. The telescope uses a camera filters To capture light in different colors. The organization said the image data was collected from 2013 to 2016.
