Saint?Just a bad woman

Philomena caressed Santa Karina's face, which was slightly red from sweating due to exercise.

She was looking at the aftermath of the sea of ​​stars through Santa Karina's blue eyes.

The most common are elliptical galaxies, which have an elliptical shape and a bright appearance.Whirlpool galaxies are disk-shaped with curved spiral arms.

Interactions between nearby galaxies may lead to the merger of galaxies or the production of a large number of stars, becoming so-called starburst galaxies.Small galaxies that lack organized structure are called irregular galaxies.

Although humans currently know very little about dark matter, it accounts for about 90% of the mass in most galaxies.Observational data show that supermassive black holes exist in the cores of most galaxies, and they are considered to be the main cause of active galactic nuclei.

Almost no galaxy exists alone; many galaxies and a certain number of galaxies are gravitational bound to each other.A group containing about 50 galaxies is called a galaxy group, and a larger group containing thousands of galaxies spanning millions of parsecs of space is called a galaxy group.

Galaxy clusters are often dominated by a giant elliptical galaxy, whose tidal forces destroy neighboring satellite galaxies and add mass to the galaxy.

Supergroups are huge collections of tens of thousands of galaxies, including galaxy groups, clusters, and some lonely galaxies. At the scale of supergroups, galaxies are arranged in sheets and filaments, surrounding huge voids.

"Lady Saint, you are too fast. Your knowledge reserve is too rich, I can't bear it at all."

During the process of preaching and imparting fluids, it was the first time that she saw such complex and profound knowledge of the sea of ​​​​stars. Philomena, who was so fascinated, almost rolled her eyes and fainted.

This is definitely a case of overbearing knowledge, rather than a comfortable fainting.

"What's wrong with this, Philomena, you know, I have always been knowledgeable, and you still have a lot to learn today and in the future."

"Lord Saint, you do know a lot... ha..."

Panting heavily and not having a good rest, Philomena started the next round.

"Please give me good guidance. I know nothing..."

So, a new class started again.

The knowledge of the Star Sea is so vast, measured in light years, that it is difficult for ordinary humans, even long-lived species and gods, to reach the other side of the Star Sea.

The end... is so far away...

Going back to what I said before, galaxies are mainly divided into three categories: elliptical galaxies, spiral galaxies and irregular galaxies.

Elliptical galaxies are classified based on estimates of their ellipticity, ranging from E0, nearly round galaxies, to E7, very elongated galaxies.These galaxies have an elliptical appearance regardless of the viewing angle.

They appear to have no structure and contain relatively little interstellar matter.Typically these galaxies will have a small number of open clusters and a small number of newly formed stars, more of them old, and a majority of mature stars rotating in various directions around the center of the galaxy.Some of their properties are similar to smaller globular clusters.

Most galaxies are elliptical galaxies, and many elliptical galaxies are formed through the interaction, collision or merger of galaxies.Giant elliptical galaxies often appear in the central regions of galaxy groups.Starburst galaxies are the result of galaxy collisions, which may lead to the formation of giant elliptical galaxies.

Extragalactic galaxies with spiral structures are called spiral galaxies, represented by S in the galaxy classification.

The spiral shape of a spiral galaxy was first discovered when observing the Canes Canes galaxy M51.Spiral galaxies have a lens-shaped central region surrounded by a flat disk.Several spiral arms extend from both ends of the bulge and are superimposed on the galaxy disk.

Spiral galaxies can be divided into two types: normal spiral galaxies and barred spiral galaxies.Normal spiral galaxies are divided into three subtypes: a, b, and c: type Sa has a large central area and sparsely distributed tightly wound spiral arms; type Sb has a small central area and has larger and more spread spiral arms; type Sc has a central area It is a small bright nucleus with large and relaxed spiral arms.

In addition to the concentration of high-luminosity O and B-type stars, supergiants, and ionized hydrogen regions on the spiral arms, there is also a large amount of dust and gas distributed on the galaxy disk.Viewed from the side, it appears as a narrow dust belt on the main plane, with obvious extinction.

In spiral galaxies, the shape of the spiral arms approximates a logarithmic spiral, which is theoretically shown to be an interference pattern caused by the consistent rotation of a large number of stars.

Like stars, spiral arms rotate around the center, but the angular rate of rotation is not constant, which means that the star will pass through the spiral arms, which are regions of high density or density waves.

As stars enter the spiral arms, they slow down, thus creating higher densities.The spiral arms are visible because the high density encourages star formation here, so there are many bright and young stars in the spiral arms.

Whirlpool galaxies usually have an overall, sparsely structured halo called a galaxy halo.Among them, the main ones are Population II objects, and the typical representative is the globular star cluster.A medium-mass spiral galaxy often has 100 to 300 globular star clusters, which are randomly scattered in the space around the galaxy disk.There may be even more sparse balls of gas further out, called galactic halos.

The mass of the spiral galaxy is one billion to one trillion solar masses, and the corresponding luminosity is absolute magnitude -15~-21.The diameter range is 5~50Kpc. The total spectral type of Sa type galaxies is K, Sb type is F~K, and Sc type is A~F.

The main objects that produce the total spectrum include both high-luminosity early-type stars and high-luminosity late-type stars.Population I objects make up the galaxy disk and spiral arms, and Population II objects mainly make up the galaxy core, galaxy halo and galaxy corona.

"Lord Saint, can you give me a glass of water?"

Perhaps she was satisfied, or she wanted to take a break, but Philomena stopped Santa Karina from wanting to start the next round.

"No problem, I'll go right now."

Santa Carina did not embarrass Philomena. She licked her fingers and licked off the sweet and salty liquid with sweet paste on it, then turned around and went to the kettle.

There was no more white steam there, and the water in the kettle had been boiling for a long time. After leaving it there, the water temperature had become normal temperature.

Turning around bluntly, the half-wet snow-white long hair drew a graceful arc in the air, like a dazzling waterfall, and the fine water mist danced under the warm light, giving it a dazzling beauty.

Santa Carolina had extinguished the lamp before to show Philomena the night view of the sea of ​​stars, but now she lit it again.

194.The gentleness of a bad woman

"Here, please drink."

Philomena took the water, and her fingertips briefly rubbed against Santa Carolina's skin.

The delicate, warm and soft touch makes your fingertips reluctant to leave.

"Is this considered halftime?"

"It's halftime if you want to."

Santa Karina smiled.There was a certain color in that smile.

"Then continue, Lady Saint."

Of course, the water will not be ordinary water. Santa Karina has added computer accessories to it in advance. It is a good thing for the two of them to explore the star sea and learn new knowledge and progress together.

This is not the first time for the two of them, and it’s not even the first time today.

After scoring two goals, they are quite familiar with each other. Whether it is adjusting the mood or comforting each other, their words and gestures are more open in all aspects.

Compared with older mothers, such as the Mermaid Queen, young girls have better experience.Most of the older people have strong or uninhibited personalities, and there is no hint of youthfulness.

Yes, even if the Immortal species is difficult to age, as long as you take care of it carefully, it will be no different from a young girl in her late teens and early 20s, but that mature charm cannot be deceived.Whether it's inadvertently or on purpose.

"My Lady Saint, you are not paying attention. What are you thinking about? Although I don't want to be jealous, Philomena still hopes that you can only think about me when doing happy things."

Burning body, scalding body temperature, it is not surprising that Philomena said this.

She is still a young girl in love, so it is not surprising that she is possessive and jealous.

Through commands, Santa Karina can make Philomena obey her words, but she has no interest in dolls without thoughts of her own and wants Philomena to be herself.As long as it does not harm her interests as the master, she is even happy to see these women competing for supremacy, so as to maintain the stability of the harem circle.

"I was just thinking, you are so arrogant now~"

Of course, Santa Karina would not be stupid enough to say what she had just been thinking in her head.

Speaking about other women in front of Philomena during such a happy moment, her emotional intelligence is so low that she deserves to be single for 100 years.

"You don't look like a priest now, but like a female publicist who accepted the gold coins and is about to serve the guests."

"If you want, Holy Lady, I am willing to be a woman to serve you at any time. In fact, I have long wanted to leave the mark of the Holy Lady on my body."

"Mark, which one do you like?"

As for Philomena's request, Santa Carina could satisfy her immediately.

But before that, she planned to listen to Philomena's request to avoid being asked too weird a request.

"For the sake of the dignity of the clergy, I hope you will not put it on my neck, but hang your exclusive ring sign in this position."

She asserted her feminine superiority.

It makes sense that a planet should have its own planetary ring.Santa Karina couldn't help but sigh that her knowledge of astronomy was taught well.

This will continue to talk about the previous spiral galaxy.For example, M101 Pinwheel Galaxy.

Whirlpool galaxies usually have an overall, sparsely structured halo called a galaxy halo.This halo is similar to the O halo which is the pinnacle of female dominance.Among them, the main ones are Population II objects, and the typical representative is the globular star cluster.

"can."

Santa Karina used magic to create a mark ring and hung it on the planetary sphere in front of her.

"Hmm..."

Then, a groan came from Philomena's mouth that sounded like pleasure and pain.

"Are you ok?"

Santa Karina asked as if she was afraid of hurting the other party.

"I'm feeling very well. Lady Saint, do you want to... try your holy sword for the first time in a long time..."

Philomena is persuasive.She had been thinking about the fullness of that holy sword for a long time.

Here we are going to talk about barred spiral galaxies.The center of a barred spiral galaxy is a bar shape, with spiral arms extending outward on both sides of the bar.

About two-thirds of spiral galaxies are barred spiral galaxies.Bars generally affect the motion of stars and interstellar gas in barred spiral galaxies, and they also affect the spiral arms.The spiral arms of barred spiral galaxies appear to emerge from the ends of short bars.In ordinary spiral galaxies, stars gush out directly from the core; they are represented by the symbol SB in galaxy classification.

For example, the Milky Way is a barred spiral galaxy with a huge galactic disk, about 3000 parsecs or [-] light-years in diameter, and about [-] light-years thick; it contains about [-] billion stars.

"How about my holy sword today? Is it big enough, exciting enough, sparkling enough, and in line with your wishes?"

Santa Karina deliberately made the holy sword a starlight color, as if she did it intentionally to fit in with today's small class.

It can only be said that when the saints play, they really have more fun than the ordinary clergy and those little lalo.

"Pfft."

However, this funny color made Philomena laugh.

The color of the sea of ​​​​stars is very charming and intoxicating, but when used in this kind of girl-girl thing, it is still the weapon of this holy sword, which really makes her laugh.

"It is indeed the best quality. But Holy Lady, you paid me so much tip today and gave me what I wanted. You can teach me more knowledge and earn back your money."

"Indeed, I have to work hard so that I won't let down the beauty and the beautiful scenery on this beautiful night."

Santa Karina leaned forward and touched the black hole in the sea of ​​stars with her fingers again.

It's a deep, dark place, mysterious and full of unknowns.

At the center of an active galaxy, there is usually a supermassive black hole, and the huge energy radiated is thought to be produced by matter falling into the black hole.

Galaxies that emit high energy in the form of X-rays are classified as Seyfert galaxies, quasars, or Lacerta stars.Active galaxies that emit radio frequencies from opposing jets erupting from their cores are classified as radio galaxies.

In the unified field theory galaxy model, these different types of galaxies are explained as the result of observations from different angles.

"Philomena, this time, there will be no second intermission."

Santa Carolina pecked Philomena on the lips. It was a shallow kiss, but her movements were deep.

This is in a black hole.In addition to the previous galaxies, there are also irregular galaxies.

First, they are irregular in shape, with no obvious core and spiral arms.They are represented by the letters Irr.Irregular galaxies account for only 5% of the brightest galaxies in the sky.

According to the galaxy classification method, irregular galaxies are divided into two categories: Irr type I and Irr II.

Type I galaxies are typical irregular galaxies. In addition to the general characteristics mentioned above, some also have vaguely irregular bar-like structures.Their mass is 100 million to one billion times that of the sun, and some can be as high as [-] billion times the mass of the sun.

They are small in size and have major diameters ranging from 2 to 9 kiloparsecs. The star population composition of Irr I is similar to that of Sc-type spiral galaxies. It is usually young star population I objects such as OB-type stars, ionized hydrogen regions, gas and dust.

Type Irr II has an amorphous appearance, with no discernible components such as stars and star clusters, and often has obvious dust lanes.Some type II irregular galaxies may be galaxies that are exploding or after exploding, while others are galaxies that have been distorted by the gravitational disturbance of companion galaxies.So type I and type II irregular galaxies may have completely different origins.

"Lady Saint... um..."

Santa Karina's movements were large, but still gentle.

That is the gentleness of a bad woman. While she goes straight to the subject, she also does not forget to calm and comfort her.

"Would you like a little milk?"

"Where did the milk come from? Why didn't I know?"

"Of course, it's specially prepared for you, the Holy Lady~"

With that said, Philomena raised her female dominance.

"Well……"

Santa Karina was forced to open her mouth.

Then, the mouth was blocked and the sound of swallowing was heard.

"tasty?"

"So thick, great..."

Stimulated by the taste buds of the ultimate milk flavor, Santa Karina herself saw more galaxies than usual.

For example, extragalactic galaxies are celestial systems located outside the Milky Way and composed of billions to hundreds of billions of stars, nebulae and interstellar matter.They are called extragalactic galaxies because they all exist outside the Milky Way. That is, all celestial systems outside the Milky Way are called extragalactic galaxies.

The Milky Way and extragalactic galaxies form the highest name for celestial bodies in astronomy - the total galaxy.The Milky Way is just an ordinary galaxy among the total galaxies.Human beings estimate that the total number of celestial bodies and celestial body systems contained in extragalactic galaxies is more than one trillion. They are like islands in a vast ocean, so they are also called "universe islands".

Santa Karina even saw an explosion of primitive energy at the first moment of the birth of the universe.As the universe expanded and cooled, gravity came into play, and the infant universe then entered a brief phase called inflation.

The tiny fluctuations in the original energy distribution were also sharply amplified from the microscopic scale with the inflation of the universe, thus forming some "troughs" along which galaxy clusters were formed.

As inflation passed, the universe returned to its usual rate of expansion as seen today.In the first second after the birth of the universe, as the universe continued to expand and cool, a large number of protons, neutrons, and electrons condensed out of the background energy in relatively "dense" energy regions.
