Stars Make Firework Supplies!

The next time you see fireworks, take a moment to celebrate the cosmic pyrotechnics that made them possible. From the oxygen and potassium that help fireworks burn to the aluminum that makes sparklers sparkle, most of the elements in the universe wouldn’t be here without stars.

From the time the universe was only a few minutes old until it was about 400 million years old, the cosmos was made of just hydrogen, helium and a teensy bit of lithium. It took some stellar activity to produce the rest of the elements!

Stars Make Firework Supplies!

Stars are element factories

Even after more than 13 billion years, the hydrogen and helium that formed soon after the big bang still make up over 90 percent of the atoms in the cosmos. Most of the other elements come from stars.

Stars Make Firework Supplies!

Stars began popping into the universe about 400 million years after the big bang. That sounds like a long time, but it’s only about 3% of the universe’s current age!

Our Nancy Grace Roman Space Telescope will study the universe’s early days to help us learn more about how we went from a hot, soupy sea of atoms to the bigger cosmic structures we see today. We know hydrogen and helium atoms gravitated together to form stars, where atoms could fuse together to make new elements, but we're not sure when it began happening. Roman will help us find out.

Stars Make Firework Supplies!

The central parts of atoms, called nuclei, are super antisocial – it takes a lot of heat and pressure to force them close together. Strong gravity in the fiery cores of the first stars provided just the right conditions for hydrogen and helium atoms to combine to form more elements and generate energy. The same process continues today in stars like our Sun and provides some special firework supplies.

Carbon makes fireworks explode, helps launch them into the sky, and is even an ingredient in the “black snakes” that seem to grow out of tiny pellets. Fireworks glow pink with help from the element lithium. Both of these elements are created by average, Sun-like stars as they cycle from normal stars to red giants to white dwarfs.

Eventually stars release their elements into the cosmos, where they can be recycled into later generations of stars and planets. Sometimes they encounter cosmic rays, which are nuclei that have been boosted to high speed by the most energetic events in the universe. When cosmic rays collide with atoms, the impact can break them apart, forming simpler elements. That’s how we get boron, which can make fireworks green, and beryllium, which can make them silver or white!

Stars Make Firework Supplies!

Since massive stars have even stronger gravity in their cores, they can fuse more elements – all the way up to iron. (The process stops there because instead of producing energy, fusing iron is so hard to do that it uses up energy.)

That means the sodium that makes fireworks yellow, the aluminum that produces silver sparks (like in sparklers), and even the oxygen that helps fireworks ignite were all first made in stars, too! A lot of these more complex elements that we take for granted are actually pretty rare throughout the cosmos, adding up to less than 10 percent of the atoms in the universe combined!

Fusion in stars only got us through iron on the periodic table, so where do the rest of our elements come from? It’s what happens next in massive stars that produces some of the even more exotic elements.

Stars Make Firework Supplies!

Dying stars make elements too!

Once a star many times the Sun’s mass burns through its fuel, gravity is no longer held in check, and its core collapses under its own weight. There, atoms are crushed extremely close together – and they don’t like that! Eventually it reaches a breaking point and the star explodes as a brilliant supernova. Talk about fireworks! These exploding stars make elements like copper, which makes fireworks blue, and zinc, which creates a smoky effect.

Something similar can happen when a white dwarf star – the small, dense core left behind after a Sun-like star runs out of fuel – steals material from a neighboring star. These white dwarfs can explode as supernovae too, spewing elements like the calcium that makes fireworks orange into the cosmos.

Stars Make Firework Supplies!

When stars collide

White dwarfs aren’t the only “dead” stars that can shower their surroundings with new elements. Stars that are too massive to leave behind white dwarfs but not massive enough to create black holes end up as neutron stars.

If two of these extremely dense stellar skeletons collide, they can produce all kinds of elements, including the barium that makes fireworks bright green and the antimony that creates a glitter effect. Reading this on a phone or computer? You can thank crashing dead stars for some of the metals that make up your device, too!

Stars Make Firework Supplies!

As for most of the remaining elements we know of, we've only seen them in labs on Earth so far.

Sounds like we’ve got it all figured out, right? But there are still lots of open questions. Our Roman Space Telescope will help us learn more about how elements were created and distributed throughout galaxies. That’s important because the right materials had to come together to form the air we breathe, our bodies, the planet we live on, and yes – even fireworks!

So when you’re watching fireworks, think about their cosmic origins!

I love the Tam Lin / Glasgow Reel, it’s a hauntingly beautiful tune BUT most of the clawhammer arrangements I know use a lot of drop thumbing (a technique I don’t like because it’s a little awkward and sometimes the base of my nail catches on the strinG hnngg)

so I made a drop thumb-free arrangement lmao

Amazing!

So the other night during D&D, I had the sudden thoughts that:

1) Binary files are 1s and 0s

2) Knitting has knit stitches and purl stitches

You could represent binary data in knitting, as a pattern of knits and purls…

You can knit Doom.

However, after crunching some more numbers:

The compressed Doom installer binary is 2.93 MB. Assuming you are using sock weight yarn, with 7 stitches per inch, results in knitted doom being…

3322 square feet

Factoring it out…302 people, each knitting a relatively reasonable 11 square feet, could knit Doom.

This Is Revolutionary Y’all. I Remember Being 13 And Refused To Go Do Any Ceremony Because My Parents

This is revolutionary y’all. I remember being 13 and refused to go do any ceremony because my parents tried to force me to go through a bar mitzvah. By virtue of the masculine name alone I just couldn’t do it. After that, I felt very alienated from the Jewish community. Having this option is so important for us to repair these binary aspects of our culture (link)

NASA Sees Our Ocean in Color. How About You?

Take a deep breath. Feel the oxygen in your lungs. We have the ocean to thank for that! Over long time scales, between 50 and 70 percent of our planet's oxygen is produced by microscopic organisms living in the ocean.

NASA Sees Our Ocean In Color. How About You?

Today is World Oceans Day! And as our planet’s climate continues to change, we want to understand how one of our biggest ecosystems is changing with it. Wondering how you can celebrate with NASA? We’ve got downloadable coloring pages and online coloring interactives to show how we study the ocean. Read on.

From Space to Sea

NASA Sees Our Ocean In Color. How About You?

Download ocean missions coloring page here Download Sentinel-6 Michael Freilich coloring page here

We use planes, boats, Earth-observing satellites and much more to study the ocean and partner with organizations all over the world. Here are a few examples:

From Sea

The Export Processes in the Ocean from Remote Sensing (EXPORTS) is one way we study the ocean from the sea to study changes in the ocean’s carbon cycle. In May, scientists and crew conducted research on three ships in the Northern Atlantic Ocean. They hope to create models to better understand climate change patterns.

From Space

Launched last year, the Sentinel-6 Michael Freilich spacecraft began a five-and-a-half-year prime mission to collect the most accurate data yet on global sea level and how our oceans are rising in response to climate change. Sentinel-6 Michael Freilich is just one of many satellites monitoring the ocean from space. Together with other Earth-observing spacecraft, the mission will also collect precise data of atmospheric temperature and humidity to help improve weather forecasts and climate models.

Finding Eddies

NASA Sees Our Ocean In Color. How About You?

Download Eddies Coloring Page The ocean is full of eddies – swirling water masses that look like hurricanes in the atmosphere. Eddies are often hot spots for biological activity that plays an important role in absorbing carbon. . We find eddies by looking for small changes in the height of the ocean surface, using multiple satellites continuously orbiting Earth. We also look at eddies up close, using ships and planes to study their role in the carbon cycle.

Monitoring Aerosols and Clouds

NASA Sees Our Ocean In Color. How About You?

Clouds coloring interactive here

Aerosols coloring interactive here

Tiny particles in the air called aerosols interact with clouds. These interactions are some of the most poorly understood components of Earth's climate system. Clouds and aerosols can absorb, scatter or reflect incoming radiation -- heat and light from the Sun -- depending on their type, abundance and locations in the atmosphere. We’re building new instruments to better understand aerosols and contribute to air quality forecasts.

The Ocean in Living Color Download PACE coloring page here

NASA Sees Our Ocean In Color. How About You?

The Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) mission will continue and greatly advance observations of global ocean color, biogeochemistry, and ecology, as well as Earth’s carbon cycle and atmospheric aerosols and clouds. It’s set to launch in late 2023 to early 2024. Want to learn more? Click here to see how PACE will collect data and here to see what PACE will see through our coloring interactives. (Make sure to check out the hidden surprises in both!)

Exploring Ocean Worlds on Earth and Beyond

Download Clouds coloring page here

NASA Sees Our Ocean In Color. How About You?

Using our understanding of oceans on Earth, we also study oceans on other planets. Mars, for example, contains water frozen in the ice caps or trapped beneath the soil. But there’s even more water out there. Planets and moons in our solar system and beyond have giant oceans on their surface. Saturn’s moon Enceladus is thought to have a massive ocean under its frozen surface, which sometimes sprays into space through massive fissures in the ice.

COVID is straight up more deadly for people of color in the western world. Like we’re not going to be the ones screened. If you have mild symptoms they’ll say you’re overreacting. I know especially black people are more at risk because we have a 20% higher chance of having Asthma. 40-60% higher chance of having lupus. And Especially Indigenous and Black people have a History in the US of being denied healthcare
