JWST May Have Finally Confirmed How Planets Take Shape

A crucial piece of evidence in support of a long-standing hypothesis on planet formation has been observed by the James Webb Space Telescope

A crucial piece of evidence in support of a long-standing hypothesis on planet formation has been observed by the James Webb Space Telescope (JWST), meaning astronomers are confident they've got a part of the cosmic process right. JWST data processed by an international team of researchers backs up the theory of 'icy pebble drift', which is thought to be vital in bringing together the dust and rocks that eventually turn into planets like our own. Simply put, icy pebble drift works like this: as tiny, ice-covered bits of material bump together in the outer reaches of a young protoplanetary disk they lose momentum, allowing them to fall towards the star into a warmer zone where their frozen coating sublimates. It's from this ring of fine debris and water vapor that rocky planets form, effectively serving as a delivery service of building materials right across a newborn solar system.

High-energy 'sun goddess' particle opens possibilities for new physics, exciting scientists

"I am personally excited to have found a new mystery in science to solve."

Over the years, scientists have managed to unveil the existence of quite a few intriguing particles, pushing the entire field of physics forward with each discovery. There's the "God Particle" for instance, aka the Higgs Boson that grants all other particles their masses. There's also the so-called "Oh My God!" particle, an unimaginably energetic cosmic ray.  But now we have a new particle in town. It's named  the "sun goddess" particle  —  and is fittingly extraordinary.  This particle has an energy level one million times greater than what can be generated in even humanity’s most powerful particle accelerators; it appears to have fallen to Earth in a shower of other, less energetic particles. Like the "Oh My God!" particle, these bits come from faraway regions of space and are known as cosmic rays. The particle has been dubbed "Amaterasu" after Amaterasu Ōmikami, the goddess of the sun and the universe in Japanese mythology, whose name means "shining in heaven." And just as its mythological namesake is shrouded in mystery, so too is the Amaterasu particle. Its discoverers, including Osaka Metropolitan University researcher Toshihiro Fujii, don’t know where the particle came from or indeed what it is. They also still aren't sure what kind of violent and powerful process could have given rise to something as energetic as Amaterasu.

Study tipps that work for me as an autistic ADHDer

(who massively struggled with any school related studying for years)

Finding out when I can focus best. I can't think by daylight. I need it to be dark outside to study. Therefore I study at night. If you can study at the time of the day you can focus best, do that. It doesn't matter if everyone else gets up at 5 am to do their ✨perfect productive morning routine✨. There's no one right time to be productive.

Stimming or moving while studying if I feel like it I can't focus (especially when I have to listen to recorded lectures for hours) when I don't move. I need to sit in my rocking chair and rock back and forth to take in any information at all. Pay attention to if you feel like moving when studying. If you're used to suppressing your stims, try to relearn stimming in a safe space if possible. The better regulated you are, the easier it will be to focus.

Nice distractions. Ali Abdaal once mentioned that he always studied with his door open so friends who passed by would come in for a little chat. You need to take breaks anyway, so think about somethings like that to make them more enjoyable. If you study at home or live alone, text your friends before you start studying, so replies will drift in while you're studying. TL;DR: 1. Study when you can focus best, you don't need to be productive in the morning if you're not a morning person. 2. Listen to your body and move if you need to move to focus. 3. Make your breaks nice, I like chatting with friends in between studying. Feel free to add what works for you : )

i like to call this girls who are normal about power lines & telephone poles (lying)

We need to get a little uncomfortable for a minute. But it's ok. You have to be uncomfortable in order to grow.

You're going to fail. You're going to disappoint people and yourself. You're going to have moments where you're so overwhelmed that you're curled in a ball crying and frustrated. You're going to miss important milestones. You're going to drop the ball so many times things seem impossible. You're going to fail. You're going to be mean. You're going to be a bad person at points. It's life. It happens. You just need to understand that it happens. And on those days where you want to dissappear and never be seen again because everything is too much, your brain is going to amplify all these faults and failures and make them seem worse.

Babe. We all go through this. We ALL fail. We ALL make awful choices and fuck people and ourselves over. We ALL will have moments where we are the villains. Where we completely fail a lot of people in our lives due to bad decisions. It will happen. Probably multiple times. What matters is that you recognize these things and make appropriate changes in your life to help make sure that next time isn't as bad. Maybe start learning time management so you're not stressed constantly and blowing up on everyone. Maybe find a healthy outlet like painting or the gym or cooking. Find small, simple joys to make life better. It's going to suck. You're going to be the bad guy. But that's not your entire life.

It's uncomfortable and hard to sit with. Sometimes things are your fault. Sometimes you make bad choices and they fuck your life up and fuck others over at the same time. It happens. You can't change the past, but you have the power to change your future. You can change your future. Talk to people. Find yourself outlets. Learn skills. Things get better, but they only do so if you put the effort for them to do so. I love you. You're trying. And that's all you can do. And one day you'll slip backwards and feel so defeated but when that happens, you'll have many tools to help you get even further. I promise babe everything will be ok.

Today’s Exhibit of the Day? It’s one of the largest amethyst geodes in the world! At about 13 ft (4 m) tall and 9,000 lbs (4,082 kg), this giant weighs about as much as three compact cars. It was born when molten magma poured from the Earth’s crust some 135 million years ago. While its dazzling purple crystals might catch your eye, this geode would have originally been composed of colorless quartz—its distinctive amethyst color deriving from millenia of natural radiation, heat, and trace contaminants. 

You can spot this geode, and other sparkly specimens, in the Museum’s Mignone Halls of Gems and Minerals. We're open daily from 10 am-5:30 pm! Plan your visit.

New laser setup probes metamaterial structures with ultrafast pulses

Metamaterials are products of engineering wizardry. They are made from everyday polymers, ceramics, and metals. And when constructed precise

The technique, developed by MIT engineers, probes metamaterials with a system of two lasers — one to quickly zap a structure and the other to measure the ways in which it vibrates in response, much like striking a bell with a mallet and recording its reverb. In contrast to a mallet, the lasers make no physical contact. Yet they can produce vibrations throughout a metamaterial’s tiny beams and struts, as if the structure were being physically struck, stretched, or sheared.

working student's survival guide for life 👩‍💻💻📱

also my phone's colors are a little happier today, yay! 🌷

everyone tells you how to launch and advance within your career, but i haven't found a lot of advice about surviving the day to day that has actually consistently worked for me. so here are some tips and tricks i learned the hard way. none of them are a magic pill, but i hope it helps even a little bit ☺️ these are also not really limited to being a working student, adulting can be a pretty universal struggle 🙈

talk to a friend — preferably a friend who shares common hobbies rather than a shared career, location, etc. you don't have to be picky by any means!! i talk to friends who are in the same career, school, etc. all the time! i've just found that when i talk to friends who share hobbies, it eliminates stress so much more effectively because the topics tend to center around our shared hobby and i've never found out later that there was an ulterior motive for the friendship because it's all just for fun!

take lots of breaks — don't worry about appearing unproductive because your work will speak for itself. i used to have my butt pretty much glued to my chair from 9-5 and most days even beyond. now, i take breaks to exercise, read a fun book, complete my studies, sometimes even take a nap, and i get the same amount of work done!! of course, knowledge plays an important role and for a time, putting in those extra hours may even be necessary, but it should definitely not be treated as the gold standard!

get a hobby — this is closely tied to the first point, and no, watching TV doesn't count (unless you actively participate in the fandom by creating fanfic, gifs, etc.). it can be hard to find something that sticks. it can also be hard to accept that this is something fun that you can suck at. but don't give up!! try many things! try things you've already tried! and for the love of all good things, do not turn your hobbies into a side hustle!! (unless you also commit to having new hobbies outside of those)

you've probably already heard at least some of this before, in which case, consider this a friendly reminder — you got this! 💕
