"Feelings are not ordinary red supergiants..."The more he looked at it, the more frightened he became, and he felt that the "sun" in another planetary system not far from here was too huge, and if he was there and witnessed it with his own eyes, it could indeed make people's hearts cold.

"If the VY star in the constellation Canis Major is in the position of Proxima Centauri, the VY star seen from the Earth will look more or less like this." Hua Zhongyue was also a little frightened.

It's just daytime, and it's hard to see another slightly brighter star from the sky, which is really unthinkable on Earth.

"It's really hard to say, but there are more factors to consider. The atmosphere here diffracts a lot more than Earth, so it looks a little clearer. That planetary system is probably closer to the solar system than Proxima Centauri, and even if the red supergiant is brighter than VY Canis Major, it should not be possible to show it so clearly and brightly. "Flying Prism hasn't put it down since he looked up and saw the red giant star, as if he wanted to carefully observe every part of the red supergiant.

"Sirius is eight .6 light-years away from us, and the brightness is still so dazzling, although this red supergiant is closer to here than the Earth is from Proxima Centauri, but it is too clear to see it, it is hard to imagine how big this red supergiant is, maybe it must belong to the supergiant column." Hua Zhongyue said and added another sentence later: It won't be bigger than Canis Major, right? ”

"It is estimated that it is not impossible for Fan Tao, who has surpassed the superstar." Flying Star said subconsciously, almost completely denying his previous first thought, because he felt that this star was probably not as close as he imagined.

VY Canis Major is a red supergiant located in the constellation Canis Major, located nearly 3,900 light-years from Earth, with an apparent magnitude of 7.95.

According to new observations, the mass and radius of the star are much smaller than originally estimated. Its mass is about 20 times the mass of the Sun, and its radius is about 1,420 times the radius of the Sun, and if VY Canis Major is placed in the position of the Sun, its edge will swallow the orbit of Saturn.

VY Canis Major is not only huge, but also has 300,000 times the luminosity of the Sun, so it is classified as a supergiant. Unlike most other supergiants that occur in binary or multistar systems, it is a single star.

VY Canis Major is also a semi-regular variable star with a photoperiod of about 2,000 days. The average density is five to ten milligrams per cubic meter. Although it is about 3 billion times the volume of the sun, it is only about 20 times the mass of the sun.

The first recorded observation of VY Canis Major was recorded in his catalog on March 7, 1801 by the French astronomer Jerome Lalande as an apparent magnitude 7th star, after which its luminosity was studied in the 19th century and its magnitude was thought to have begun to decline in 1850.

Since 1847, VY Canis Major has been known to be a crimson star. Nineteenth-century observations found that VY Canis Major had at least six bright detached regions, so it was thought that it could be a multistar.

Today, scientists already know that these bright areas are actually the bright parts of the clouds around VY Canis Major. Optical observations in 1957 and high-resolution observations in 1998 confirmed that VY Canis Major had no companion star.

University of Minnesota professor Roberta Humphrey predicts that the diameter of the constellation Canis Major VYCMa will be about 1,800 to 2,110 times the radius of the sun. If you place the Canis Major VY in the center of the solar system, its diameter exceeds the orbit of Saturn.

It takes eight and a half hours for light to orbit it, while light orbits the sun for 14.5 seconds. But as the observations progressed, the diameter of the star was re-measured, and the current estimated size is 1,420 solar diameters.

According to the three-dimensional formula of the sphere, its volume is between 58320000000000 and 929100000000 times the volume of the sun.

If the Earth is a sphere with a diameter of one centimeter, and the Sun is a sphere with a diameter of one hundred and nine centimeters, the maximum diameter of Canis Major VY is predicted to be about 2.3 kilometers.

Currently, VY Canis Major is one of the largest stars known to man. If you sit on a passenger plane traveling at 900 kilometers per hour and circle the Canis Major VY, you need to fly for 900 years. And if the interior of the Canis Major star is hollow, it can easily fit about three billion suns.

The current state of Canis Major VY is very unstable and erupts a considerable amount of material into the surrounding clouds. Astronomers using observations from the Hubble Space Telescope predict that it will end its life as a hypernova within the next 100,000 years.

Extreme supernovae theoretically produce gamma-ray bursts that would destroy parts of the galaxy and destroy life in the vicinity of Miè for several light-years. The mass of the Canis Major VY is enough to form a black hole, and the probability is quite high.

"Didi...... "Very suddenly, something flew out of the space ring of the Flying Prism Star uncontrollably, almost startling the Flying Prism Star, is this the rhythm of the hell?

His own space ring is not under his control, and he flies out of things, which seems a bit crazy... Could it be that something big has happened that has led to such an unusual event?

"What's the panic?" Hua Zhongyue kept watching, and didn't say anything, it seems that this kind of machine-born thing has great immunity to similar things.

"Huh? It turned out to be ......" Flying Prism's eyes widened, wasn't this the hilt of his own Flame Sword? Why did you fly out? It's weird... I don't think I want to use the Flame Sword right now...

......A burst of light flashed on the hilt of the sword, and a soft sound sounded.

"What's going on?" Prism was confused.

"There must have been some big accident, right?" Hua Zhongyue doesn't seem to be very clear, but she knows the main point.

"Big accident? Isn't this the location of the four best of the galaxy? Or maybe we can't go back? Speaking of the former, Prism Star didn't feel anything, but when it came to the latter, he felt a little afraid, and the consequences of not being able to go back were very bad.

"I can't say, looking at the current situation, the Flame Sword should have an unexpected move, you go and take a look. Seeing that this place is so perfect, I'm afraid that the unexpected moves that will appear will be very unusual. Hua Zhongyue directly pointed out the reason at this moment.

"Unexpected moves?" Only then did Flying Prism remember that the Flame Sword seemed to really have such an effect. It's just that I haven't seen it before, after all, if there is no major event, there is no condition to stimulate it, but now it is stimulated.

Thinking of this, Flying Prism couldn't help but look at the hilt of the sword floating in front of him, and there were really two more Chinese characters on it: the whole dragon eighteen slashes, and the afterimage hurricane slash.
