There are countless galaxies in the universe, and naturally there are countless celestial bodies, and some of these celestial bodies are very unique, like high-speed rotating pulsars, which emit regular electromagnetic signals. Recently, NASA posted a photo taken by Hubble Space Telescope on its official website? Star jewelry box? In an ancient globular cluster deep in the universe, thousands of stars gather together, flashing and dazzling.

The report said that this ancient? Star jewelry box? It is a globular cluster named ngc6397. Thousands of stars in the cluster are shining, like shining jewels and colorful light bulbs, which are dazzling in beauty.

Seeing the pictures, it is estimated that many people will sigh, how beautiful, like the most beautiful fireworks, there are so many beautiful stars in the universe. This globular cluster, named ngc6397, is one of the closest clusters to the Earth. The new measurement method sets the distance of this cluster as 7800 light years, with an error of only 3%.

Why are there such beautiful clusters? We know that only some stars in the universe can shine by themselves. Like the sun, most celestial bodies cannot give off light by themselves. This cluster is attracted by hundreds to thousands of stars connected by weak gravity, and the photothermal radiation emitted by the stars radiates to the surrounding celestial bodies, and then such a spectacular and beautiful scenery is formed.

So will there be life in this globular cluster? Although there is little possibility of life in this cluster, there is nothing absolute in the universe. Only when space technology is developed in the future can we go directly to this cluster thousands of light-years away for field investigation.

We have to sigh the magic of the universe, only you dare not think, nothing is not in the universe. At present, human space technology is still in its infancy, and we can only observe celestial bodies in the depths of the universe through astronomical telescopes, and the conclusion is only speculation. Only by observing these celestial bodies at close range can we get accurate data.

With the continuous progress of human science and technology, in the future, human beings will create spaceships capable of interstellar navigation, and the distance in the universe will no longer be a problem. At that time, we could explore the depths of the universe at the speed of light or even faster than light. And a beautiful globular cluster like ngc6397, we can also observe it at close range, and I believe it will be more spectacular then.
