After teleporting Xiao Yu to this unknown star field, the ghost race transformed from human souls disappeared, and no one knows where they went.
Xiao Yu sighed and began to make plans for his future.
At present, the first thing to determine is where this place is and whether it is still within the Milky Way. The second thing is to determine how much time has passed in the outside world during this day's journey.
This is a large nebula with a length and width of more than ten light years. This nebula is a luminous nebula.
There are three types of nebulae, namely luminous nebulae, reflection nebulae and dark nebulae. Luminous nebulae, as the name suggests, emit visible light by themselves. Reflection nebulae can reflect the light of other stars, and dark nebulae have no stars nearby.
There are also no stars, so it is not visible in visible light, but it can be found by looking for dark areas against a bright background.
The nebula Xiao Yu passed through before encountering the Moruton civilization was a dark nebula. The nebula Xiao Yu is in now is a luminous nebula.
This nebula is an extremely efficient and huge star factory. Countless interstellar dust gathers to form stars. The ultraviolet rays emitted by young stars ionize the interstellar dust, so they appear slightly red in the visible light band.
So the starry sky here is not dark, but red. Here, you can see a magical phenomenon. Bright young stars are embedded in the reddish sky, like bright gems, very beautiful.
But behind the beauty, there is danger hidden. Because there are a large number of young stars gathered here, the radiation level here is dozens of times higher than that in the rest of the universe. Moreover, the bigger the star, the shorter its age. The shortest-lived giant star,
Its lifespan is even less than 10 million years.
After a star dies, it will have different destinations according to its mass. A star with a mass similar to the sun will turn into a white dwarf after death. After the supernova explosion, the remaining core mass exceeds the Chandrasekhar limit, which is about 1.44
If it is twice the mass of the sun, a neutron star will form in its core.
If after the supernova explosion, its core mass still exceeds the Oppenheimer limit, which is about 3.22 times the mass of the sun, it will directly collapse into a black hole.
So it is certain that behind this extraordinarily beautiful reddish sky, there must be more than one neutron star, white dwarf and other stars hidden, and even the most dangerous star in the universe, a black hole.
At this stage, these dangerous stars are fatal to Xiao Yu. Xiao Yu decided that he must be careful in his actions here.
"It's so beautiful here...but where is this?" Xiao Yu sighed.
Perhaps because these stars are covered by dense dust belts, there are no stars here that have been included in the Sky of Heroes by Xiao Yu. If you want to find the initial coordinate point, you must search outside.
Xiao Yu's gaze extended beyond the nebula. Because of the obscuration of the nebula, the stars outside the nebula appeared extremely dim and even invisible. To this end, Xiao Yu used a variety of observation methods, including visible light bands, X-ray bands,
Observation methods such as infrared and ultraviolet bands were used together.
"This is an aging red giant star. Its mass is too small to even be qualified for a supernova explosion. The distance... is about three thousand light years. It is not included in the Sky of Heroes."
Xiao Yu shook his head and gave up on this goal after including it in the Heroes of the Sky.
"This is a red dwarf star, with a mass only ninety-three times that of Jupiter. As a star, it is really too small. It is not included in the Sky of Heroes." After including it, Xiao Yu gave up this idea.
Target.
"Well? This is... a pulsar? How come its rotation speed, pulse intensity, and nebula are so familiar?"
A pulsar is a type of neutron star. If a neutron star can emit high-frequency pulses, it is called a pulsar.
When searching for the thirty-fifth star, Xiao Yu found a familiar pulsar. Immediately, Xiao Yu started searching in the Sky of Heroes. One-tenth of a second later, Xiao Yu found a pulsar that was similar to the pulsar.
All the data of this pulsar are very consistent with each other.
Xiao Yu was shocked and immediately launched a more detailed observation.
