unironically i think we need to bring back computer labs because APPARENTLY some people WERENT taught basic computer literacy and internet safety in school
things about computers/the internet i think kids should be formally taught in schools because theyre important to know and the amount of soon to be grown adults i know who know NOTHING about any of these is quite frankly almost all of them (and resources to learn if you dont know these things, because its never to late to get better with computers)
how to troubleshoot by yourself when you have a technical problem
what common file types are
some very basics on how to use ""developer tools"" on your computer (because i cant think of a better way to refer to them) like task manager and command prompt (and their mac equivalents, terminal and activity monitor ofc)
how to read and understand a privacy policy and what your personal data is, as well as what it being collected actually means and steps you can take to keep it private
how to understand terms of service
(hey. if you have trouble with reading legalese and worry about being able to understand these policies anyways, here's a site that gives basic summaries of privacy policies and ToS)
what a cookie actually is
internet privacy and your digital footprint!! seriously i dont know why we stopped teaching people that they shouldnt be putting their entire real identity online in a world where your online actions can ruin you irl
basic safety measures like antivirus software (and why you should use it or if the built in one on windows or mac is enough for you) and backing up your computer (also a mac guide)
common keyboard shortcuts (and on mac)
as an additional note: things i think everyone should know on computers and the internet but schools may bit hesitant to teach about for whatever moral/legal standards schools pretend to operate on
vpns and adblockers! (btw for most of these where you can pay for things im purposefully not recommending any specific software but seriously just use ublock origin for an adblocker)
how to not get a virus while pirating something
what a temporary email is and when to use one
red flags that you shouldn't trust a website (and how to quickly check the security of a site)
what javascript on a website does and how to disable it to get around paywalls
ok one last addition! if you want to take it one level higher, i think learning the very basics of at least one programming language is good for people. it makes computers less scary and it makes you feel very cool, and a lot of people get discouraged about it because it seems overly complicated and hard to learn outside a formal classroom setting, so heres some resources for learning the very basics of python (because i consider it the easiest language to learn and knowing one language will make it easier to learn others)
an online compiler so you dont need to download anything or worry about running code directly on your computer if that makes you nervous
a basic video guide to introduce you to python and walk you through beginner steps
a guide to some syntax and commands you should know (this was literally my lifeline in my first CS class)
some performance tasks to give you things to code to practice and assess yourself
No, you see, I wish to be an author. Not in marketing. Or an influencer. I wish to tell my stories, be told I did a fantastic job, and then go back to my hovel to scribble some more. I am delicate of constitution and awkward in crowds.
Important note- You should take rest if you need it! We as a society need more rest than we can afford under the current system. That being said, I wanted to encourage us to live our best lives, spend time meaningfully, and achieve our goals in the short-term! Sometimes the activities I thought were restful like lying on the couch and scrolling on my phone didn’t actually make me feel any more rested. When I got up to go for a walk or pulled out a hobby even when I was tired, I ended up having way more energy than I expected at the start.
I’m the biggest advocate there is for rest and self care- we don’t need to be productive or push ourselves so hard, but it’s also good to balance that with motivation and doing the things in life that matter to you. You may never fully feel 100% ready or rested, so let’s practice being brave and not being afraid of our tiredness! ☺️✨
If we could see our galaxy, the Milky Way, from the outside, it would look like an enormous, bedazzled pinwheel. Vast sprays of stars form spiral arms that curl outward from a bright center that bulges like the yolk in a fried egg. Dark, dusty tendrils darken some regions, while glowing pink gas clouds light up others.
We have a pretty good idea of the Milky Way’s overall structure, but since we’re nestled inside it, fine details are hard to see. Those clouds of gas and dust strewn throughout interstellar space block our view, especially of the far side of the galaxy. Astronomers have used observations from different telescopes to piece together our galaxy's anatomy. Let's scrub up and dive in!
An artist’s concept of our Milky Way galaxy’s central bulge.
At the heart of our galaxy, an enormous swarm of about 10 billion mostly old stars crowd into a slightly peanut-shaped region around 10,000 light-years across called the bulge. The innermost stars dance around an invisible object. By measuring the stars’ orbits, scientists have calculated that the central object must be as hefty as about 4 million Suns.
This unseen behemoth is a monster black hole called Sagittarius A* (A* is pronounced “A-star”). Its gravity is so powerful that if you came within 7 million miles (12 million kilometers) or so –– less than a tenth of Earth’s distance from the Sun –– you’d never be able to escape its grip, no matter how hard you tried! But don’t worry, Sagittarius A* is a pretty friendly giant; it’s largely dormant, releasing only faint flickers of X-rays and radio waves.
An artist’s concept of our Milky Way galaxy’s disk.
The disk, which is home to the bulk of the Milky Way’s stars, extends out from the bulge like the brim of a sombrero. It’s around 100,000 light-years wide and divided into two parts. The thin disk is about 1,000 light-years from top to bottom, and the thick disk (which isn’t as densely populated by stars) extends above and below it for another few thousand light-years. So, the thick disk is like a bagel, and the thin disk is like a generous layer of cream cheese spread inside it.
The thin disk hosts our galaxy’s spiral arms, which look like they spin around the Milky Way like bicycle spokes, although they actually work more like galactic traffic jams. We live along one of these dense areas in an arm called the Orion Spur. All of the Milky Way’s arms extend outward from the bar –– a rotating structure of stars in the middle of the galaxy that’s about 16,000 light-years long.
The edge of a nearby stellar nursery called NGC 3324, found at the northwest corner of the Carina Nebula, forms the “mountains” and “valleys” spanning this image captured by the James Webb Space Telescope.
The spaces between stars in the disk aren’t quite empty –– they’re home to the interstellar medium, which is made of dust and gas. Dark, smoky ribbons of dust wind through the starlight, clumping up here and there to form clouds of molecules. To some astronomers, the dust is a nuisance that blocks things they’d like to study. But for others, the dust is the target –– interstellar dust is both the leftover crumbs from stars long dead and raw material from which new stars and planets may form.
An artist’s concept of our Milky Way galaxy’s stellar halo.
A sparse smattering of incredibly old, faint stars lives in a football-shaped “halo” that’s about 300,000 light-years across, encasing the disk and bulge. Stars there are tiny, which means they burn through their nuclear fuel so slowly they can live 12 billion years or even longer! Many of them formed early in the universe’s history, before many generations of stars enriched the galaxy with heavier elements than hydrogen and helium.
This Hubble Space Telescope image shows one of the Milky Way's many globular clusters. Known as NGC 6388, the cluster is more than 10 billion years old.
The stellar halo is also home to at least 150 globular clusters –– huge, spherical collections of ancient stars bound to each other by their mutual gravity. These groups of tens of thousands or even millions of stars are the ultimate squad goals. They’re so tightly packed together, sometimes just a fraction of a light-year apart, that from Earth they look like glittery disco balls. And they’re practically inseparable, sticking together for billions of years.
This artist’s concept visualizes gamma-ray bubbles discovered by NASA’s Fermi Gamma-Ray Space Telescope. From end to end, the bubbles extend 50,000 light-years, or roughly half of the Milky Way’s diameter. Hints of the bubbles’ edges were first observed in X-rays (blue) by ROSAT, a Germany-led mission operating in the 1990s. The gamma rays mapped by Fermi (magenta) extend much farther from the galaxy’s plane.
Vast “bubbles” of gamma rays, each about 25,000 light-years long, stretch into the stellar halo from the center of the galaxy. Scientists found them by surprise in data from NASA’s Fermi Gamma-ray Space Telescope. The mysterious structure may be only a few million years old, perhaps leftover from a massive burst of star formation or an eruption from Sagittarius A*.
An artist’s concept of our Milky Way galaxy’s dark matter halo.
An even larger halo of dark matter (about a million light-years across) cocoons the stellar halo. This mystery material has mass, so its gravity pulls on things we can see. But it isn’t visible itself, and no one knows exactly what it’s made of. This strange stuff makes up about 90 percent of our galaxy’s mass.
This illustration, taken from a computer simulation, visualizes the Milky Way's dark matter halo (as well as several surrounding dark matter clumps) in blue.
Scientists know it’s there because if it weren’t, stars would orbit much faster near the galaxy’s center than on the outskirts. But for the most part, orbital speeds are pretty constant regardless of distance from the center. Stars toward the edge of the disk whirl around so quickly that they should be flung off into space if there weren’t something keeping them anchored to the Milky Way. Dark matter holds our galaxy together.
This collage shows the Milky Way in 10 different wavelengths of light, from radio waves to gamma rays. By studying our galaxy in different types of light, astronomers can learn far more than they could otherwise.
While astronomers have mapped much of our galaxy’s bulge, disk, and stellar and dark matter halos, key details about its structure and hidden components remain unknown. NASA is tackling the Milky Way’s mysteries with a fleet of space telescopes designed to explore the universe in different ways.
For example, our upcoming Nancy Grace Roman Space Telescope will peer through dust with a large field of view to map stars, dust and gas clouds on the far side of the galaxy, revealing hidden structures, spiral arms, and stellar nurseries. Our picture of our home galaxy will soon be clearer than ever before!

yknow how the greener parts of apple skin are tan lines from where leaves and branches obscure the sun? I’m surprised I’ve never seen anyone utilize that for printmaking
"i don't want to be a burden" you're worth carrying. i don't care if you'd be worth it to you; you're worth it to me. i smile every time i think of you. and buddy you're just gonna have to figure out how to cope w that <3
