Our Sun has an entourage of planets, moons, and smaller objects to keep it company as it traverses the galaxy. But it’s still lonely compared to many of the other stars out there, which often come in pairs. These cosmic couples, called binary stars, are very important in astronomy because they can easily reveal things that are much harder to learn from stars that are on their own. And some of them could even host habitable planets!
New stars emerge from swirling clouds of gas and dust that are peppered throughout the galaxy. Scientists still aren’t sure about all the details, but turbulence deep within these clouds may give rise to knots that are denser than their surroundings. The knots have stronger gravity, so they can pull in more material and the cloud may begin to collapse.
The material at the center heats up. Known as a protostar, it is this hot core that will one day become a star. Sometimes these spinning clouds of collapsing gas and dust may break up into two, three, or even more blobs that eventually become stars. That would explain why the majority of the stars in the Milky Way are born with at least one sibling.
We can’t always tell if we’re looking at binary stars using just our eyes. They’re often so close together in the sky that we see them as a single star. For example, Sirius, the brightest star we can see at night, is actually a binary system (see if you can spot both stars in the photo above). But no one knew that until the 1800s.
Precise observations showed that Sirius was swaying back and forth like it was at a middle school dance. In 1862, astronomer Alvan Graham Clark used a telescope to see that Sirius is actually two stars that orbit each other.
But even through our most powerful telescopes, some binary systems still masquerade as a single star. Fortunately there are a couple of tricks we can use to spot these pairs too.
Since binary stars orbit each other, there’s a chance that we’ll see some stars moving toward and away from us as they go around each other. We just need to have an edge-on view of their orbits. Astronomers can detect this movement because it changes the color of the star’s light – a phenomenon known as the Doppler effect.
Stars we can find this way are called spectroscopic binaries because we have to look at their spectra, which are basically charts or graphs that show the intensity of light being emitted over a range of energies. We can spot these star pairs because light travels in waves. When a star moves toward us, the waves of its light arrive closer together, which makes its light bluer. When a star moves away, the waves are lengthened, reddening its light.
Sometimes we can see binary stars when one of the stars moves in front of the other. Astronomers find these systems, called eclipsing binaries, by measuring the amount of light coming from stars over time. We receive less light than usual when the stars pass in front of each other, because the one in front will block some of the farther star’s light.
Twin stars don’t always get along with each other – their relationship may be explosive! Type Ia supernovae happen in some binary systems in which a white dwarf – the small, hot core left over when a Sun-like star runs out of fuel and ejects its outer layers – is stealing material away from its companion star. This results in a runaway reaction that ultimately detonates the thieving star. The same type of explosion may also happen when two white dwarfs spiral toward each other and collide. Yikes!
Scientists know how to determine how bright these explosions should truly be at their peak, making Type Ia supernovae so-called standard candles. That means astronomers can determine how far away they are by seeing how bright they look from Earth. The farther they are, the dimmer they appear. Astronomers can also look at the wavelengths of light coming from the supernovae to find out how fast the dying stars are moving away from us.
Studying these supernovae led to the discovery that the expansion of the universe is speeding up. Our Nancy Grace Roman Space Telescope will scan the skies for these exploding stars when it launches in the mid-2020s to help us figure out what’s causing the expansion to accelerate – a mystery known as dark energy.
Astronomers like finding binary systems because it’s a lot easier to learn more about stars that are in pairs than ones that are on their own. That’s because the stars affect each other in ways we can measure. For example, by paying attention to how the stars orbit each other, we can determine how massive they are. Since heavier stars burn hotter and use up their fuel more quickly than lighter ones, knowing a star’s mass reveals other interesting things too.
By studying how the light changes in eclipsing binaries when the stars cross in front of each other, we can learn even more! We can figure out their sizes, masses, how fast they’re each spinning, how hot they are, and even how far away they are. All of that helps us understand more about the universe.
Thanks to observatories such as our Kepler Space Telescope, we know that worlds like Luke Skywalker’s home planet Tatooine in “Star Wars” exist in real life. And if a planet orbits at the right distance from the two stars, it could even be habitable (and stay that way for a long time).
In 2019, our Transiting Exoplanet Survey Satellite (TESS) found a planet, known as TOI-1338 b, orbiting a pair of stars. These worlds are tricker to find than planets with only one host star, but TESS is expected to find several more!

When Kougami takes Akane out to eat after picking her up (see First Inspector film for those who don't know), he catches her staring at him several times during the meal. Eventually he decides to ask her why she's doing this-
"Is there something on my face? You look like you want to say something."
And Akane gives him her sweet smile, shakes her head and gestures in apology before replying
"It's nothing, Kougami-san. I just wanted...to make sure you were really there, that's all."
Kou raises a brow and Akane returns to happily chowing down on the yummy food he bought her
Bonus HC: After this, Kougami ends up staring at Akane cause she looks so happy when she eats and he can't get enough of seeing her like that
These are all the PP clips made into Shinkane scenes by Detective Masterclass. Enjoy!

I’ve heard this has been translated already but several cute anons and some users insisted that I did it anyway and I couldn’t just ignore them or refuse. So there you have it. ^_^“
Too bad they didn’t put this in the movie. It would totally blow the fandom away. I may not be a shinkane shipper, but I genuinely enjoyed this complete version of the scene. It has a nice the-old-PP vibe to it. Especially this exchange was very nice:
“You’ve really grown up,” Kougami muttered heartily.
“Is that so?”
Tsunemori already feels embarrassed as she says this.
And the part about how, even though they finally met as fellow humans, there’s a case getting in their way. Lol. What were they thinking, leaving it out? Anyway, I hope you’ll enjoy this. <3

Evening in the rebel army base. The light’s turned off in Kougami’s room. Tsunemori was using the bed, and Kougami was trying to fall asleep, lying on blankets on the floor. At any rate, it was after he had struggled through the battlefield. Once he calmed down and tried to think, he felt fatigued. The next morning Kougami planned on having a talk with Sem about their further actions.
“…”
Kougami Shinya and Tsunemori Akane. A strange, barely tangible tension drifting between the two couldn’t be brushed away. Even despite the fact that she was tired, only Tsunemori’s mind was clear of nervousness. No, was it clear just because she was too exhausted? Anyway, Tsunemori couldn’t fall asleep and left Kougami’s room.
She was looking out the window of a roofed passage.
“Ah…”
The number of power generators seemed insufficient. The Guerillas kindled real fire instead of using lighting equipment. It was those traditional watch fires.
The night sky was beyond belief beautiful. The silhouettes of the stars were sharp as jewels. The lighting at the Guerilla camp was at any rate poor. Speaking of lighting intensity, these watch fires would be less than a tenth part of street lights used in the Tokyo metropolitan area. When the ground is dark, the sky is clearly visible.
“The sky is awesome.”
Kougami was also awake.

nsfw. sylus' new myth pv is giving me ideas, especially this scene.
blurb. not proofread

the way i just know it’s one of his favorite position to have you in.
as he fucked you slow and deep from behind. savoring the pleasure of each thrust, his hand locks your fucked out face in place and he smirked. while the other one firm on your lower belly, applying just the right amount of pressure making sure you feel every inch of him.
“tired already, sweetie?” he said lazily, and you couldn’t even form a single coherent sentence as your eyes rolled back. your whole body enveloped in all muscles, the contact left your skin burning for more.
"s-sylus, please..." you whimpered, not having an idea on what it was exactly you're begging for. a low chuckle escaped him, his hips kept its pace as his finger trailed lower, lower, until his precise movement found your sensitive spot, refusing to move just yet.
"please what? you should already know by now how to beg properly," he whispered against your ear, the gravel in his voice turned you on even more, if that's even possible. he groaned, the anticipation made you squeezed the life out of him in response as you whined softly.
"at least this lips of yours are honest, hm?" he began to rub your clit, building a coil in your stomach as it gets tighter. merciless, you felt as though you were under a spell as his motion on your clit reached a relentless pace, your lewd moans filled the room. you gripped his arm for support, the stimulations were too much to bear.
until suddenly he slowed down, his thrust became sloppy as his finger rested on your nub. your tearful gaze couldn't glare at him any quicker, to have all that pleasure ripped away from you in seconds. yet the man only had an expression of amusement as he looked at you intently. the smug smile never left his face.
"what's the rush? the night is still young, isn't it?"

Re-make of "Afloat", digital.
I felt like I had a really good idea with my old copic drawing where Mai was dreamily floating carefree in the air with koi fishes. I still like the old piece, but I really had a vision where she's shining and the fishes were more animated, so here's the new version.
Hello and happy new year for all ヽ(*´∀`*)
I hope that everyone has had a happy holiday ヾ(^□^★)
I’ll start the year publishing “ Umbrella ” is part of my story: Renegade, you could say it’s the beginning of everything. \(*^▽^*)/
I will always respect the people who draw manga, it is terribly difficult, I spent almost 3 days just coloring ( ´゚д゚)
There are many things I wanted to finish and publish, but the beginning of the semester is around the corner, so I will give my best effort. (*´Д`*)ノ
Hope you like. ( ^w^)
