Leaving Rainbow City, the trip of the Hemu Stellar family is still very smooth, mainly because they are in a good mood! Not only did he rescue Gzina in Rainbow City, but he also became an honorary citizen, and everyone had to be happy for a while.

People are like this, when they are in a good mood, their steps are brisk, and they are in a hurry much faster than usual.

For some reason, in recent days, the road ahead has not become very smooth, and there are always some stumbles.

Butani was at the front, and for a while he was in charge of opening the way, complained: "Mom, there is garbage in this area from nowhere, there is a mess of everything, and the most is rotten stones. ”

"Second child, then let's slow down a little, don't worry, if you're tired, let the third prince star be in front for you for a while."

"I'm not tired of my mother, but I feel a little irritated when I look at these things that get in the way."

Seeing that Butani was working so hard in front, Prince Xing also cheered up and kept patrolling around Hemu's star, cleaning up the debris that leaked through the net in time to protect the star Hemu.

In the distance, an extremely bright light appeared in front of them, and after a while another one appeared, neither of them had ever seen such a bright star, and they seemed to illuminate the entire constellation nearby.

"What's that, and why is it so bright?" Butany asked first.

"It's a supernova, the brightest star in the night sky, but it's an explosion, it's dangerous, and we'd better get out of the way." Hem Stellar used her erudition to explain to the children.

Both children were curious, especially Butarni, who was particularly adventurous, and the more dangerous the place, the more he wanted to go and see what was going on.

"Okay, kids, let's go and see, but don't get too close, Stellar Hemu knows how powerful the supernova explosion is, and he's on his guard."

Moving on, the interstellar dust on the road became denser and denser, and there were more and more rubble tiles, and the Hemu family was like entering a quagmire, and it took some effort to move forward with every step.

Butani had no choice but to use his housekeeping skills, and he sent out an X-ray, and some of the rubble was shattered, drifting to both sides along with the dust, and only then did he barely open a narrow passage.

Prince Star found that the trajectory of these departing gravel dust was very strange, they were neither scattered in place nor left straight in a certain direction, but quickly formed small whirlpools.

When two small vortices meet, they merge together to form a large vortex, which in turn merges into a larger vortex.

"Hurry up, kids, it's a magnetic vortex, and if you fall into it, you'll be in trouble." Hem Star urges urgently.

The two children were watching intently, and when they heard their mother's urging, they didn't dare to delay, and hurriedly rushed forward.

After walking for a while, they found more and larger magnetic vortices, some of which had gathered the rubble into a large stone ball.

When they finally got out of the quagmire of gravel and dust, and Hemu was a little tired and wanted to rest a little, Butani made a new discovery in front of them.

"Mom, come and see, what's that?" Butany pointed to a sphere in front of him that glowed with a faint white light.

Hemu looked at it intently, "I don't know, I've never seen a star like this." ”

This star, which confuses everyone, is indeed strange, to say that it is a star, it does not have strong sunlight; If you want to say that it is a planet, it has a very large mass and emits a faint light.

In fact, its real name is White Dwarf, and the folk also give it a better name - Diamond Star.

Hem Stellar had never seen such a star, and he didn't know what to call it, so he had to give it a temporary name: "Weak White Star".

The weak white star also sits at the center of a large magnetic vortex, with a lot of dust surrounding it and revolving around it.

A ripple of time and space swept over the Hemu family, as if brushed by a soft feather on their cheeks, and a blazing light rose in front of them, and another supernova exploded.

Hem Stellar had seen supernovae, but had never encountered such a dense supernova explosion, which was very rare, and she forgot about her exertion just now, and decided to move on and get closer to find out.

After a few more days, they finally got a little closer, and Hem found that the supernova here was different, and of course, she didn't have the opportunity to observe it at such a close distance.

The supernova explosions I have seen before are when a star suddenly reaches extreme brightness, and after a while, a strong cosmic wind blows, which is the strong stream of electromagnetic radiation particles produced by the explosion, which is why she reminds children to beware of danger.

This radiation, at close range, can completely destroy a planet.

However, the supernova exploded here, and the family did not feel the cosmic wind, only the strong light and the accompanying ripples of time and space.

On closer inspection, she seemed to have found some clues: these supernovae inhabit the vast magnetic vortex with strong centripetal gravity and hard shells; Every time a supernova erupts, only space-time ripples can penetrate the shell and escape, while the radiation waves generated by the explosion are imprisoned inside the vortex.

Seeing the reason, Hemu Xingxing was relieved, and what she was most worried about was the cosmic wind particle flow, which would cause harm to the children.

Walking through the supernova vortex, Prince Star has also made a new discovery.

A balloon-like star appeared in front of it, it emitted an orange-red light, it looked soft, as if it was full of gas, and its volume was hundreds of times larger than that of Hem Star, which looked extremely magnificent and gorgeous.

Prince Star liked this red balloon very much and wanted to go over and take it off, but was stopped by Hem Stellar.

"I know this, kids, it's a red giant, it's a gas star, although it's beautiful, but you can't play with it in your hand, if you accidentally play with it, you will be disfigured."

Prince Xing was very concerned about his appearance, and when he heard his mother say this, he was so frightened that he quickly stopped and gave up the idea just now.

The two children hurriedly bypassed the red giant star and ran to the front.

"Children can't be too curious, otherwise they will get into trouble." Hem Stellar sighed softly and followed the children's footsteps closely.

Here, the bleak atmosphere gradually thickened, as if it were a Death Star area; The stars here no longer occupy a vortex each, but there are several, or even dozens of stars in a large maelstrom.

These stars include cool stars and dead planets; They do not emit light, and the spheres have no temperature, but they are scattered in the magnetic vortex, and they rotate in a haphazard manner, and a few of them sink at the bottom of the vortex, lazily not moving.

The children didn't feel anything, they were still curiously looking around, exploring, but Hemu was a little sad in her heart, seeing these dead stars couldn't help but remind her of her future, whether it would end like this in the end.

"Let's go, boys, it's lifeless, it's not a good place." Hem couldn't help but urge.

The attentive Prince Xing found that his mother was in a bad mood, and hurriedly responded: "Okay, Mom, then let's go faster." ”

Butani also reacted, hurriedly returned to his post, and continued to open the way in front of him, while exploring this mysterious magnetic world.

If you have a broader perspective, you will find that the area that the Hemu family is traversing is actually a giant celestial vortex of a larger scale, and all the stars they have just experienced are in this magnetic vortex.
