Here's A Reminder To Stop Shortening The James Webb Space Telescope's Name To "James Webb" And Instead

Why Quasars Ignite

There's your winning smile, a bright summers day, then there's Quasars ! Unlike the latter, Quasars are amongst the brightest objects in the Universe, often shining out more energy than the entirety of the galaxy that hosts them.

While we know a fair bit about what they are, how they begin has been a debate since they were first found.

Most galaxies have a supermassive black hole at their centre, our Milky Way has one 4.5 million times the mass of our own Sun, and in galactic terms, that's fairly light weight, there are black holes within 60 million light years of us several billion times the mass of our Sun, real goliaths, which tend to sit at the centre of Elliptical Galaxies.

Qasars are incredibly active supermassive black holes, so the question remains, why are some quasars and others not, what causes this to happen ?

A team of astronomers from the Universities of Sheffield and Hertfordshire have found an interesting bit of information which may hint towards the answer. In a study of Quasars, they have discovered that galaxies that are home to a Quasar are three time more likely to be in a state of interaction or collision with another galaxy.

This leads them to believe that the galaxy merger is responsible for piling an enormous quantity of material towards the black hole, causing it to grow incredibly quickly but also as messy eaters, pushing out much of it in the form of radiation in beams emanating from the poles.

One consequence of this is the galaxy is quenched of dust and gas, the very elements needed to create new stars, and is likely the reason most elliptical galaxies have such monster black holes, the remnants of all the star making material consumed, and that pushed out, leaving behind stars old enough to live on since that happened.

Astronomers solve the 60-year mystery of quasars, the most powerful objects in the universe

Scientists have unlocked one of the biggest mysteries of quasars—the brightest, most powerful objects in the universe—by discovering that th

Black hole physicists annoy me so much. They could literally say anything about what happens in a black hole and there is no good way of proving otherwise. They literally just play around with maths and make stuff up. "if you go through the ring singularity, you might come out elsewhere" "where?" "idk" like get a real job Paul

i feel like the crimew thing shows how much queer discourse dehumanizes people. crimew is an extremely cool & talented person who's like. literally embodying 'be gay do crime' in it's truest form, but the minute that people find out it is a bi lesbian, suddenly thats. all they can think of her as? like no consideration of how it Hacked The Fucking No Fly List, everyone can only focus on her lesbian identity crimes. because none of the people who do this shit can ever see "wrong" queer people as people. they treat identity discourse like it's the biggest issue in the world even to this absolutely absurd level. doesn't matter what they do for queer liberation doesn't matter if they are happy, if you Do Identity Wrong all you are in their eyes are a freak who's personally responsible for lesbophobia or transphobia or w/e. funny how that works

"If you go on T you won't look like a pretty anime boy, you're gonna look like an ugly man!" is so funny because I'm SE Asian, have been on T for 3 years with subtle (but satisfactory) changes, and definitely still have been told I look like an anime boy or a K-pop idol (because racism.) I do like to take care of my appearance and make an effort to look nice and stylish, but that's not a "pretty anime boy" or "K-pop idol" thing, I'm just A Guy who wants to look nice and pretty and cool. It's such an odd statement cause from my perspective it definitely does not consider the experience I described above, LMAO. It's assuming a "little white girl who doesn't know any better and likes anime" person, or something like that. (Just putting this out there because transmascs of color definitely need to be heard more, and transitioning on T experiences are all very very different.)

And anyways, the condescending way people talk down to trans men who do want to look like their cute/pretty fictional men transition goals is so weird... Like, what's wrong with that, anyways? Some fictional guys are really designed nicely, and may give new perspective on masculinity or maleness that people IRL may not show depending on where you live. Anyways, I think even if T changes you to be more masculine than you expected, you can still present in a way inspired by characters and styles you admire if you so like.

And the other side -- what's wrong with looking like an "ugly" man? I feel like that's saying any masculine trait is "ugly," so if you think that please reevaluate yourself. Looking more like a man Is Kind Of The Entire Point. Many transmascs will embrace that masculinity, and that's not anything bad, wrong, or poisonous. If you think it makes them look uglier or more like a predator or enemy, I want you to know that is not a very kind mindset to have toward transgender people, or to any man in general; it's rather in poor taste, and shows you are not an ally to transgender people. So if you do desire to be an ally, I urge you to reevaluate yourself and challenge yourself on what being a "man" entails, what being "masculine" entails. Because it's not inherently immorality or ugliness, it's just a gender.

This framing of masculinization as something to be warned against, that we don't know what we're getting into is not very cool, definitely ignoring we have our own agency and choices and feelings about our bodies. Like, when we go on T, often we know what it will do to us, and what kind of person we are gender-wise. We're making that choice for ourselves, absurd that we're treated like we don't know any better. We know. Don't treat it like a warning that we'll become less desirable types of people.

To Stand on a Comet

This footage was taken by ESA Rosetta probe on the Comet 67P/Churyumov-Gerasimenko.

The snow fall is in fact a number of things, firstly the background stars moving as the comet rotates, secondly the zippy streaks are in fact cosmic rays and then there is dust moving about too, so none of it snow !
