The arms of the Galaxy are coated with regions of formation of bright hydrogen pink stars, sets of newborn blue stars and obscure dust tracks that provide the raw material for future generations of stars.

This delicate shell, photographed by the NASA/ESA Hubble Space Telescope, appears to float serenely in the depths of space, but this apparent calm hides an inner turmoil. The gaseous envelope formed as the expanding blast wave and ejected material from a supernova tore through the nearby interstellar medium. Called SNR B0509-67.5 (or SNR 0509 for short), the bubble is the visible remnant of a powerful stellar explosion in the Large Magellanic Cloud (LMC), a small galaxy about 160 000 light-years from Earth. Ripples in the shell’s surface may be caused either by subtle variations in the density of the ambient interstellar gas, or possibly be driven from the interior by fragments from the initial explosion. The bubble-shaped shroud of gas is 23 light-years across and is expanding at more than 18 million km/h.
Hubble’s Advanced Camera for Surveys observed the supernova remnant on 28 October 2006 with a filter that isolates light from the glowing hydrogen seen in the expanding shell. These observations were then combined with visible-light images of the surrounding star field that were imaged with Hubble’s Wide Field Camera 3 on 4 November 2010.

New images from NASA’s Hubble Space Telescope are helping researchers view in unprecedented detail the spiral arms and dust clouds of a nearby galaxy, which are the birth sites of massive and luminous stars.
The Whirlpool galaxy, M51, has been one of the most photogenic galaxies in amateur and professional astronomy. Easily photographed and viewed by smaller telescopes, this celestial beauty is studied extensively in a range of wavelengths by large ground- and space-based observatories. This Hubble composite image shows visible starlight as well as light from the emission of glowing hydrogen, which is associated with the most luminous young stars in the spiral arms.
M51, also known as NGC 5194, is having a close encounter with a nearby companion galaxy, NGC 5195, just off the upper edge of this image. The companion’s gravitational pull is triggering star formation in the main galaxy, as seen in brilliant detail by numerous, luminous clusters of young and energetic stars. The bright clusters are highlighted in red by their associated emission from glowing hydrogen gas.
This Wide Field Planetary Camera 2 image enables a research group, led by Nick Scoville (Caltech), to clearly define the structure of both the cold dust clouds and the hot hydrogen and link individual clusters to their parent dust clouds. Team members include M. Polletta (U. Geneva); S. Ewald and S. Stolovy (Caltech); R. Thompson and M. Rieke (U. of Arizona).
Intricate structure is also seen for the first time in the dust clouds. Along the spiral arms, dust “spurs” are seen branching out almost perpendicular to the main spiral arms. The regularity and large number of these features suggests to astronomers that previous models of “two-arm” spiral galaxies may need to be revisited. The new images also reveal a dust disk in the nucleus, which may provide fuel for a nuclear black hole.
The team is also studying this galaxy at near-infrared wavelengths with the NICMOS instrument onboard Hubble. At these wavelengths, the dusty clouds are more transparent and the true distribution of stars is more easily seen. In addition, regions of star formation that are obscured in the optical images are newly revealed in the near-infrared images.
This image was composed by the Hubble Heritage Team from Hubble archival data of M51 and is superimposed onto ground-based data taken by Travis Rector (NOAO) at the 0.9-meter telescope at the National Science Foundation’s Kitt Peak National Observatory (NOAO/AURA) in Tucson, AZ.

Appearing like a winged fairy-tale creature poised on a pedestal, this object is actually a billowing tower of cold gas and dust rising from a stellar nursery called the Eagle Nebula. The soaring tower is 9.5 light-years or about 90 trillion kilometres high, about twice the distance from our Sun to the next nearest star.

The spectacular new camera installed on NASA’s Hubble Space Telescope during Servicing Mission 4 in May has delivered the most detailed view of star birth in the graceful, curving arms of the nearby spiral galaxy M83.
Nicknamed the Southern Pinwheel, M83 is undergoing more rapid star formation than our own Milky Way galaxy, especially in its nucleus. The sharp “eye” of the Wide Field Camera 3 (WFC3) has captured hundreds of young star clusters, ancient swarms of globular star clusters, and hundreds of thousands of individual stars, mostly blue supergiants and red supergiants.
The image, taken in August 2009, provides a close-up view of the myriad stars near the galaxy’s core, the bright whitish region at far right.
WFC3’s broad wavelength range, from ultraviolet to near-infrared, reveals stars at different stages of evolution, allowing astronomers to dissect the galaxy’s star-formation history.
The image reveals in unprecedented detail the current rapid rate of star birth in this famous “grand design” spiral galaxy. The newest generations of stars are forming largely in clusters on the edges of the dark dust lanes, the backbone of the spiral arms. These fledgling stars, only a few million years old, are bursting out of their dusty cocoons and producing bubbles of reddish glowing hydrogen gas.
The excavated regions give a colorful “Swiss cheese” appearance to the spiral arm. Gradually, the young stars’ fierce winds (streams of charged particles) blow away the gas, revealing bright blue star clusters. These stars are about 1 million to 10 million years old. The older populations of stars are not as blue.
A bar of stars, gas, and dust slicing across the core of the galaxy may be instigating most of the star birth in the galaxy’s core. The bar funnels material to the galaxy’s center, where the most active star formation is taking place. The brightest star clusters reside along an arc near the core.
The remains of about 60 supernova blasts, the deaths of massive stars, can be seen in the image, five times more than known previously in this region. WFC3 identified the remnants of exploded stars. By studying these remnants, astronomers can better understand the nature of the progenitor stars, which are responsible for the creation and dispersal of most of the galaxy’s heavy elements.
M83, located in the Southern Hemisphere, is often compared to M51, dubbed the Whirlpool galaxy, in the Northern Hemisphere. Located 15 million light-years away in the constellation Hydra, M83 is two times closer to Earth than M51.

The sharpest image ever taken of the large “grand design” spiral galaxy M81 is being released today at the American Astronomical Society Meeting in Honolulu, Hawaii.
A spiral-shaped system of stars, dust, and gas clouds, the galaxy’s arms wind all the way down into the nucleus. Though the galaxy is located 11.6 million light-years away, the Hubble Space Telescope’s view is so sharp that it can resolve individual stars, along with open star clusters, globular star clusters, and even glowing regions of fluorescent gas. The Hubble data was taken with the Advanced Camera for Surveys in 2004 through 2006. This colour composite was assembled from images taken in blue, visible, and infrared light.

Providing, of course, that Mutsuki does not kill Touka. But I sincerely doubt that will happen (though a fake-out death wouldn’t shock me).
(Before we begin, I should say that I’ll be referring to Mutsuki with male pronouns because that’s what Mutsuki has, thus far in the story, wanted to be referred to as. It does not necessarily reflect my opinion on Mutsuki’s gender, I don’t feel qualified to give an opinion, and I think people should use whatever pronouns they feel best fit Mutsuki.)
Firstly, we have Urie, who clearly has romantic feelings for Mutsuki and cares about him as a person as well. @dreamofcentipedes wrote a fascinating meta speculating on where Mutsuki’s character is going, and it’s definitely a solid theory (even if I still have hope for Mutsuki, lol.) The meta points out that Urie is the Touka to Mutsuki’s Kaneki, and therefore I do think we can expect some sort of confrontation between them eventually regardless of where Mutsuki’s character is heading. However, the difference is that Urie may be in a healthier place at this point in :Re than Touka was in in the original Tokyo Ghoul. We haven’t seen enough of him since his breakdown after his confrontation with Donato to say for sure, but the small smile he gives Saiko here is something he would not have given earlier in the series.
If Urie continues to grow in a healthy direction and confronts Mutsuki, I think it’s not entirely out of the question for this confrontation to invert the bridge scene in Tokyo Ghoul 120 and go well. But that’s just speculation.
Secondly, we have Mutsuki’s dissociative issues. Mutsuki himself seems to be unable to reconcile what he’s done in his dissociative states with the person he wants to be, much like Kaneki struggles to reconcile being a ghoul and being human at the same time. For Mutsuki to move forward, he needs to face the truth and, essentially, stop lying to himself. He is capable of being both kind and of committing atrocities, and he needs to accept that he’s capable of both. (Which may involve a final resolution of Mutsuki’s gender issues, whatever that may be.) Mutsuki seems to be on the path to doing that right now, although he’s choosing to allow his violent side to rule in going after Touka. @linkspooky wrote a fantastic meta in which they stated that Mutsuki needs to kill “Haise Sasaki” to break his downward spiral, and I agree. Which is to say, I think Mutsuki has further to fall (likely through injuring/kidnapping Touka)–but, that act and Kaneki’s reaction to it may also break Mutsuki’s image of Haise Sasaki.
And lastly, we come to Aura Shinsanpei. I would say my odds for Mutsuki living or dying are about 50-50. Aura, on the other hand, I’m fairly certain will die. This smile is what a death flag looks like:
(Aura’s smile also contrasts with Mutsuki, who looks uncomfortable or exasperated.) But interestingly, Aura seems to represent the part of Mutsuki that needs to break in order for Mutsuki to grow in a healthy direction. As the smile shows, Aura is capable of being quite sadistic. Aura is a liar by omission, much like Mutsuki.
(Seriously, Aura, this is not the kind of thing you cover up.) Aura even physically resembles Torso, whose habits Mutsuki has started to adopt post-captivity.
Actually, the new Quinx seem to represent something the other Quinx have to overcome to continue to grow in a heathy direction: Higemaru is a cinnamon roll, but he idolizes Urie, and Urie craves esteem (via promotion and now the idea of marriage), not realizing that his crushing need to prove himself and constant jealousy of characters like Takeomi actually inhibits him from recognizing what he already has (Higemaru’s respect, Saiko’s love–though I lean towards thinking that it is platonic). Hsiao fits least well in this pattern, but she does seem to be be content with Saiko (along with everything else) as is, and while on the surface level that’s beautiful, she also isn’t actively encouraging Saiko to grow as a result. Saiko’s childishness, while endearing (I love her), is something she needs to grow away from. I do feel as if Hsiao and Saiko made some steps towards both growing when they worked together to save Urie, as Hsiao became the supporter of Saiko there (and I will say I feel Hsiao has by far the best chance of any new Quinx of surviving the series, though Higemaru could make some steps via breaking out of his idolization of Urie).
But back to Aura: It’s no coincidence that as Mutsuki spirals deeper into his darker instincts, he teams up with Aura. I basically have no hope that Aura will survive the series. If/when he does die, likely as a result of his and Mutsuki’s current plots, it could be symbolic of Mutsuki’s darkest instincts dying, or at least Mutsuki’s exploration thereof.
I could totally be wrong though, and often am when I try to predict how stories will go, so who knows. But this is basically to say that I think there is still hope for Mutsuki.
(If you want to read an update about what I think about where Mutsuki is going post chapter 123, you can read that here.)
