117 - From the Rockies to Alaska: Why the West Is So Different
If the Appalachians are ancient, rounded, and quiet — worn down by hundreds of millions of years — then what are the Rockies? The answer is: still under construction. This episode picks up where the eastern geography series left off, and heads west into some of the most dramatic, geologically active, and ecologically distinct landscapes on the continent.Young Mountains and the Rain Shadow That Made the WestThe Rocky Mountains are young by geological standards — sharp, dramatic, still rising. Unlike the Appalachians, they haven’t been worn down yet. The Cascades and Sierra Nevadas do something remarkable to the weather: they intercept the moist Pacific air as it moves inland, force it upward, cool it, and squeeze out enormous amounts of rain on the western slopes. By the time the air crosses the mountain crest and descends on the eastern side, the moisture is gone. The land on the far side sits in what’s called a rain shadow — which is why the western slope of the Cascades is one of the wettest places in North America while Oregon’s east side and the Great Basin are semi-arid desert. Same latitude, completely different worlds.The Great Basin: Where Rivers Go to DisappearBetween the Rockies and the Sierra Nevadas lies one of the continent’s most unusual landscapes: the Great Basin. Rivers here have no outlet to the ocean. They flow inward toward salt lakes and desert playas and simply evaporate. The Great Salt Lake is the largest remnant of an ancient inland sea called Lake Bonneville, which once covered much of the region. The ecology is highly specialized — sagebrush, juniper, pronghorn antelope (the fastest land animal in North America) — and it all exists because the mountains blocked the rain entirely.The Pacific Coast: Cold, Productive, and Geologically VolatileThe Pacific Ocean is older, colder, and geologically more violent than the Atlantic. The western coast of North America sits on the Ring of Fire. The Juan de Fuca plate pushes under the North American plate, building the Cascades and threatening a mega-earthquake along the Pacific Northwest coast. The California Current flows southward, bringing cold water from the north and driving upwelling from the deep ocean that produces some of the richest marine life on Earth — kelp forests, fish populations, seabird colonies, sea otters, gray whales, humpback whales. The Pacific Flyway runs this entire coastline from Alaska to Mexico, carrying shorebirds, waterfowl, raptors, and songbirds in enormous numbers every spring and fall.Temperate Rainforests, the Gulf of Mexico, and the Longleaf PineWhere Pacific moisture hits the mountains directly, you get the temperate rainforests of the Pacific Northwest — the Olympic Peninsula, the western slopes of the Cascades — 140 inches of rain in some locations, trees of staggering size and age. Jill’s Olympic Peninsula road trip is one of her all-time favorite travel memories. Moving south and east, the episode fills in the missing pieces: the Gulf Coastal Plain (ancient seafloor, karst landscape, cypress swamps, bayous), the once-vast Longleaf Pine Savannah (now reduced to less than 3% of its original 90 million acres), and the Gulf of Mexico itself — not a warm-water backdrop but the engine that drives the entire continent’s weather and a critical corridor for the most dramatic bird migration event in North America: the trans-Gulf crossing.Alaska, the Boreal Forest, and How It All ConnectsAlaska is its own category — larger than Texas, California, and Montana combined, with more coastline than the entire lower 48. It holds tundra, boreal forest, temperate rainforest, glaciers, active volcanoes, and some of the most productive marine environments on Earth. And the boreal forest — the taiga — stretching across Canada, Russia, Scandinavia, and Siberia, is the breeding ground for nearly 3 billion birds, more than half the species that migrate through North America. That yellow-rumped warbler in your backyard in September? There’s a reasonable chance it hatched in a spruce bog in northern Canada. North America is not a collection of separate places. The birds connect them. The rivers connect them. The weather connects them.Jill’s Linkshttp://jillfromthenorthwoods.comhttps://www.buymeacoffee.com/smallstepspodTwitter - https://twitter.com/schmernYouTube @BuzzBlossomSqueakBy choosing to watch this video or listen to this podcast, you acknowledge

116 - The Ancient Forces That Made North America
North America doesn't just look remarkable — it is remarkable, and not in a flag-waving way. In this episode of Buzz, Blossom & Squeak, I want to take you on a deep-time journey across the continent and show you how the landscape beneath your feet was shaped by forces that most of us never think about. This is the older history, written in rock, ice, and river — and you can read it in everything from the Great Lakes to the path of a migrating shorebird.The Canadian Shield: The Continent's Ancient HeartAt the center of the story is the Canadian Shield — an enormous region of exposed ancient rock stretching across much of Canada down into northern Minnesota, Wisconsin, and Michigan. These are some of the oldest rocks on the planet, scraped bare by glaciers and dotted with the kind of lakes that make the Northwoods feel like the last frontier. That rugged, unfinished feeling you get in places like the Boundary Waters or the Upper Peninsula is not your imagination. It's geology.The Ice That Built and DestroyedThe same glaciers that stripped the north bare also left behind something extraordinary: the rich, mineral-laden soil of the Midwest that now feeds a significant portion of the planet. Glaciers crushed ancient rock into fertile sediment as they moved, and when the ice retreated, Iowa and Illinois inherited the result. Destruction in one place, extraordinary productivity in another.The Mississippi System: Rivers That Made CitiesBetween the Rockies and the Appalachians sits a vast interior plain, and through it runs one of the world's great river systems. The Mississippi and its tributaries — the Missouri, the Ohio, thousands of smaller streams — formed the continent's original transportation network. Cities like St. Louis, Minneapolis, Memphis, New Orleans, and Chicago didn't emerge by accident. They grew where the geography made them inevitable.Bird Migration and the FlywaysThe same geology that shaped the rivers also shaped the skies. The Mississippi Flyway exists because birds follow the same corridors that water carved — river valleys, wetland chains, habitat corridors laid down by retreating glaciers. When I stand in a marsh in early May watching shorebirds drop, exhausted and hungry, I think about how this landscape has been receiving them for thousands of years. The birds know the way because the land itself taught them.The Appalachians: Old, Quiet, and ExtraordinaryThe Appalachians don't announce themselves the way the Rockies do, but they are ancient beyond comprehension — once as tall as the modern Himalayas, now worn into gentle, biodiverse ridges. The southern Appalachians are among the most biologically rich temperate zones on Earth, with more salamander species than anywhere else on the planet. They also shaped the entire early history of European settlement on this continent, acting as a wall that confined civilization to the Atlantic coast for generations.The Atlantic Coast and the Gulf StreamThe Atlantic coast isn't a boundary — it's an ecosystem. The Gulf Stream moderates the entire eastern seaboard's climate, keeping mid-Atlantic winters far milder than the latitude would suggest. The estuaries, salt marshes, and tidal flats along this coast are among the most productive ecosystems on Earth, serving as nurseries for fish and critical stopover habitat along the Atlantic Flyway. The ocean doesn't just sit beside the continent. It feeds it.Next week we continue west. If you have a favorite corner of North America, I'd love to hear about it.Jill’s Linkshttp://jillfromthenorthwoods.comhttps://www.buymeacoffee.com/smallstepspodTwitter - https://twitter.com/schmernYouTube @BuzzBlossomSqueakBy choosing to watch this video or listen to this podcast, you acknowledge that you are doing so of your own free will.

115 - How Baby Birds Learn Everything
Last week on a camping trip, I had three moments that made me laugh out loud — and then sent me down a rabbit hole about one of nature's most entertaining and overlooked stories. A young downy woodpecker was earnestly pecking a metal pole. A juvenile blue jay locked eyes with me and immediately fled in apparent horror. And on a snag in the woods, a baby barred owl stood hollering for its mother like a very indignant toddler. None of them knew what they were doing yet. And that, it turns out, is exactly the point.Two Strategies: Precocial vs. AltricialNot all birds are born equal. Precocial birds — ducks, killdeer, turkeys — hatch with their eyes open, down feathers in place, and the ability to walk and swim within hours. Altricial birds — songbirds, woodpeckers, owls, eagles — hatch helpless and blind, entirely dependent on their parents. The difference comes down to survival strategy: ground-nesters need mobility fast; cavity and platform nesters can afford slow, intensive development.What That Woodpecker Was Actually DoingThe downy pecking my metal feeder pole wasn't malfunctioning — it was running experiments. Young altricial birds have their core instincts baked in, but the skill of knowing *where* to apply them takes time. The pole was a data point. An incorrect one, but the bird was calibrating. That's how it works.The Screaming Owl on the SnagYoung barred owls go through what birders call the "branching stage" — when they've outgrown the nest but can't fly yet. They climb out onto nearby branches and do exactly what mine was doing: hollering. The parents still come. They feed the young owl for weeks, gradually requiring it to work harder for each meal. That outraged noise on a snag eventually becomes the composed, silent presence we associate with owls.Fledging Is Not GraduatingWhen a young bird leaves the nest, it's not independent. A fledgling robin hopping badly across your lawn, looking lost or even injured, is almost certainly fine. The parents know where it is. Don't rescue it unless the bird is visibly injured or a predator is present.How They Find Their WayHere's what genuinely amazes me: baby birds hatched in the Northwoods this summer may fly to Central or South America this fall — without a map, often without a parent. Young indigo buntings learn to navigate by watching the rotation of the night sky during a specific developmental window. Researchers altered the apparent sky in planetariums and shifted the birds' internal compass. A brain the size of a walnut doing celestial navigation before its first birthday.The next time you see a young bird doing something completely ridiculous — pecking a metal pole, fleeing a harmless human, hollering from a branch at 10 a.m. — you're watching competence being built in real time. It's one of the best shows nature has to offer.Find me at jillfromthenorthwoods.com or email jill@startwithsmallsteps.com.Timestamps0:00 Introduction — three campsite moments2:40 Precocial vs. altricial — two birth strategies8:16 The branching stage — why owls scream on snags12:09 Fledging: what it really means16:23 Navigation — finding south without a map19:19 What parenting looks like when success means goodbyeJill’s Linkshttp://jillfromthenorthwoods.comhttps://www.buymeacoffee.com/smallstepspodTwitter - https://twitter.com/schmernYouTube @BuzzBlossomSqueakBy choosing to watch this video or listen to this podcast, you acknowledge that you are doing so of your own free will.

114 - Why Birds Get Lost: The Science of Vagrancy and Range Expansion
In July 2023, a volunteer doing routine piping plover counts at a Wisconsin wildlife area saw a flash of pink out of the corner of his eye. He stopped. He looked again. He started making phone calls. What he was looking at was a roseate spoonbill — a large, flamingo-pink wading bird with a spatula-shaped bill — last confirmed in the state in 1845. Within days, birders were driving from hundreds of miles away, fifty people showing up on a Saturday just to stand at the edge of a wetland and look at a bird that had no business being there.So how does that happen? And what does it mean when it does?The Vocabulary: Vagrant, Accidental, WandererNot all out-of-range birds are the same thing. A vagrant is a bird that shows up outside its normal range — unusual, but not unheard of. An accidental is rarer still: a bird so far outside its range that a sighting is essentially a once-in-a-lifetime event. That spoonbill was an accidental — the gap between sightings was 178 years. A wanderer is something else: typically a young bird in its first couple of years, still sorting out navigation, following instinct or wind or food somewhere further than planned.Four Mechanisms That Send Birds Off CourseThe first and most intuitive is weather. A bird riding the winds ahead of a storm system can end up hundreds of miles off course. Tropical storm remnants and hurricane tails are particularly dramatic — when Hurricane Laura moved through in August 2020, magnificent frigatebirds (birds that belong over warm tropical ocean water and almost never touch land) turned up over the Mississippi River, with sightings as far inland as Tulsa, Oklahoma. Experienced birders have learned to look for rare sightings in the hours after major inland storms.The second mechanism is genetic — and this one is fascinating. A small European bird called the blackcap warbler was the subject of landmark research in the 1990s. Two populations of the same species migrate in different directions — one group goes southwest in autumn, the other southeast. Researchers crossbred captive birds from each population and raised the offspring in total isolation, with no parents to follow and no experienced birds to imitate. When tested, the young birds flew compass headings that averaged out between their parents’ routes. The migratory direction isn’t learned. It’s encoded in the genome. A bird flying the wrong direction isn’t making a mistake the way a human would — it’s executing a program that has a bug.The third mechanism is inexperience. A UW-Madison wildlife ecologist described juvenile birds as being like a 16-year-old driver: they know how to drive, they just don’t know how to go where they want to go. Young birds have the hardware, the instinct, and the fuel-burning capacity to migrate. They just haven’t made enough trips to lock in the route. They overshoot, drift, follow the wrong flock to the wrong landform.The fourth mechanism is population pressure. When a species has a strong breeding year, more young birds compete for limited resources and push further from their normal range. The roseate spoonbill was already appearing in unusual numbers in the Great Lakes and New England from 2018–2021 before the Wisconsin sighting in 2023. That wasn’t random. It was a population large enough to start edging northward.When “Getting Lost” Becomes “Moving In”The ibises in a Wisconsin marsh I love to visit tell a different story. White-faced ibis and glossy ibis began showing up in small numbers, then in larger ones, then across multiple counties. By 2025, the Southern Wisconsin Bird Alliance was writing about regular sightings at many locations. Black-necked stilts followed a similar arc: considered accidental in 1991, first documented nesting pair at Horicon Marsh in 1999, and now dozens counted in a single season. I was just at Horicon on vacation and counted 14 in a single outing. That’s not a bird getting lost. That’s a bird finding a new home.The Bird List Is Not a Closed DocumentWhat’s happening in the Midwest right now with spoonbills, ibises, and stilts is a reminder that a state bird list isn’t fixed — it’s a living record. The birds your grandparents birded for are not exactly the birds you’ll find today. Some species have declined. Some have moved north. A few have shown up in directions no one expected. And we now have tools to track all of it in real time.eBird is a continuously updated, crowdsourced map of bird sightings contributed by millions of observers worldwide. When that spoonbill showed up in Wisconsin, it had statewide recognition by the end of the day. You don’t have to be an expert to contribute — a free account takes five minutes to set up, and every checklist you submit makes the record more complete. You become a citizen scientist.

113 - Reading the Sky: What Storm Colors Are Telling You
Why does the sky turn green when a tornado is coming? Why do storm clouds go black? And what does a 19th-century volcanic eruption in Indonesia have to do with one of the most famous paintings in the world? In this episode of Buzz, Blossom & Squeak, we finish our spectrometry series by bringing it closest to home — reading the colors of the sky itself, and learning what they’re telling us.The Blue Sky: Our BaselineA clear blue sky is the result of Rayleigh scattering — a process identified by British physicist Lord Rayleigh in the 19th century. Sunlight traveling through the nitrogen and oxygen molecules of the atmosphere scatters the short blue wavelengths far more powerfully than the long red ones. The result: blue light bounces in every direction, filling the sky, while red and orange travel a more direct path. Our eyes also favor blue over violet, which is why the sky appears blue rather than purple even though violet wavelengths exist.Sunsets, Sunrises, and the Long Path Through AirAt sunset, the sun’s light must travel at a much longer diagonal through the atmosphere before reaching our eyes — roughly 30 times more atmosphere than when it’s directly overhead. That means more scattering. Blue goes first. Then green. Only the warm wavelengths survive: orange, crimson, deep red, pink, gold. Every sunset is Rayleigh scattering happening live.Krakatoa, “The Scream,” and Volcanic PurpleWhen Krakatoa erupted in 1883 — one of the most violent volcanic events in recorded history — it injected billions of tons of sulfuric material into the upper atmosphere. For months afterward, sunsets around the world turned extraordinary shades of blood red, violet, and even green. In London, people thought it was a fire on the horizon. Fire departments were dispatched. And in Norway, a decade after the eruption, Edvard Munch described the blood-red sky he saw while walking with friends — the moment that inspired “The Scream.” That painting may be, in part, a spectral record of Krakatoa’s aftermath.Dark Clouds and Why They Go BlackClouds start white because tiny water droplets scatter all wavelengths equally, producing white light. As storm clouds grow taller and denser, their thickness blocks light from passing through entirely. A towering cumulonimbus reaching 40,000 to 60,000 feet absorbs rather than scatters — and the cloud that was white becomes gray, then dark, then nearly black. The darkness is measuring the cloud’s water content.The Green Sky: A Warning You Can’t IgnoreThe sickly yellow-green of a tornado sky is one of the most visceral color signals in nature. The leading explanation: the deep red-orange of late afternoon sunlight, already stripped of blue by the atmosphere, mixes with the intense blue light scattered inside the massive water column of a supercell. Red plus blue-green equals that unsettling cast. Hail intensifies it — ice crystals absorb red and scatter blue-green wavelengths. If the sky goes green, take cover.The sky is a giant spectrometer, and it’s always telling us something. We just have to know how to read it.Jill’s Linkshttp://jillfromthenorthwoods.comhttps://www.buymeacoffee.com/smallstepspodTwitter - https://twitter.com/schmernYouTube @BuzzBlossomSqueakBy choosing to watch this video or listen to this podcast, you acknowledge that you are doing so of your own free will.

112- Why Is Water Blue? The Science of Color in Lakes, Oceans, and Ice
Why is Lake Superior almost black on a stormy day and impossibly blue on a calm one? Why does the Caribbean look turquoise when it's made of the same H2O? And what's happening when glacier ice glows that eerie deep blue inside a crevasse? Water doesn't have a color the way a cardinal has red feathers. What we see when we look at water is physics in action — selective absorption, light scattering, depth, biology, and the geometry of the sun. In this episode we break down exactly how it works.Why Pure Water Is Blue at AllWater molecules absorb light selectively. They absorb energy at the red end of the spectrum more readily than at the blue end — it has to do with how the hydrogen and oxygen atoms vibrate at frequencies that match red and infrared wavelengths. So as sunlight enters water and travels deeper, the reds disappear first, then orange and yellow fade, then green weakens. Blue and violet penetrate deepest. The blue light that survives gets scattered back toward your eyes. A single glass of water is barely detectable. A deep lake or ocean makes the filtering unmistakable.Deep Blue: Lake Superior and Open OceanIn deep, cold, clear water — away from river mouths and shorelines — selective absorption plays out fully. By 30 feet, red disappears from underwater life almost entirely. By 30 meters, saltwater has absorbed nearly everything except blue. Lake Superior behaves like a small inland ocean: deep, cold, and clear enough that on a calm day with nothing stirring up sediment, it can appear impossibly, purely blue. That blue is not reflection — it's what's left after everything else has been filtered out.Turquoise: Why Tropical Water Looks DifferentTropical water like the Caribbean involves a second mechanism: a pale, reflective bottom. The water is shallow enough that light reaches the sandy or coral floor, reflects back upward, and passes through a thin column of water on its way to your eyes. The red wavelengths still get knocked out, but you get some blue-green light mixing back in with the blue — giving you that bright, warm turquoise. The shallower the water and the more reflective the bottom, the brighter and lighter the color. That's why it can look almost mint green over white sand in just a foot or two of water.Glaciers, Sea Caves, and the Blue GrottoWhen light enters a glacier through compacted ice or a sea cave through a narrow underwater opening, something beautiful happens. The ice or water column absorbs the reds, and concentrated blue scatters in every direction through the confined space. In a glacier crevasse, that creates the sensation that the ice is glowing from within. In the Blue Grotto at Capri, light enters through an underwater opening, reds are absorbed by the column of water, and blue illuminates the entire cave and its walls. Same physics. Different stage.Tannins, Algae, and Living ColorNot all water color comes from light physics alone. Tea-colored rivers carry dissolved organic material — tannins leaching from decaying plant matter upstream. Algae blooms can turn a lake green, and certain bacteria produce red and pink pigments as a kind of biological sunscreen. Pink lakes like Lake Hillier in Western Australia and Lake Retba in Senegal are colored entirely by living organisms, not by chemistry. The biology of a body of water can override its physics entirely.Whitecaps, Clouds, and Equal ScatteringWhen waves break, they trap millions of tiny air bubbles. Those bubbles are large enough to scatter all wavelengths of light equally — not just blue. Every color comes back to you at once, and the result is white. The same reason clouds are white: water droplets large enough to scatter the full spectrum. A whitecap is, in a sense, a momentary cloud forming at the surface of the water. When a sea that was deep navy suddenly goes pale and foamy, the water hasn't changed — its physics has.Structural Color: Blue Jays and the Same RulesBlue jays have no blue pigment in their feathers. Their barbules contain nanostructures with air pockets that scatter blue wavelengths and absorb red and orange — the same selective physics as the ocean. If you find a blue jay feather and hold it at the wrong angle, the blue disappears. Cardinals really are red; blue jays only appear blue. Hummingbird throats, dragonfly wings, glacier ice, and the open Pacific are all playing by the same set of rules.Jill’s Linkshttp://jillfromthenorthwoods.comhttps://www.buymeacoffee.com/smallstepspodTwitter - https://twitter.com/schmernYouTube <a href="https://www.youtube.com/@smallstepswithgod" rel="no

111 - Spectrometry in Space: What Every Planet Is Telling Us
We've never touched Mars. We've never scooped up Pluto's frost or sifted through Jupiter's cloud layers. And yet scientists can describe the chemistry of every planet in our solar system with remarkable precision. This episode is about how that's possible — and why the colors you see when you look up at the night sky are some of the most information-rich things in the universe.The Philosopher Who Said It Was Impossible In 1835, French philosopher Auguste Comte declared that the physical composition of stars and distant worlds would forever lie beyond human knowledge. Within 25 years, he had been proven wrong — not by luck, but by a fundamental discovery about what light actually carries. The story of Kirchhoff, Bunsen, and those dark lines in the solar spectrum is one of the most dramatic reversals in the history of science.How Planets Speak in Light Planets don't generate their own light — they reflect the Sun's. But that reflected light isn't the same as what left the Sun. As sunlight passes through a planet's atmosphere and bounces off its surface, specific elements and compounds pull out their characteristic wavelengths. The result is a spectrum full of gaps — a chemical fingerprint that survives billions of miles of travel to reach our telescopes.A Tour of the Solar System in Color Each planet has a story written in its reflected light. Mars's rust-red surface broadcasts iron oxide chemistry and a history of possible liquid water. Venus's blinding brightness hides an atmosphere of carbon dioxide and clouds made of sulfuric acid droplets. Jupiter's banded cloud layers reveal ammonia ice, and Neptune's vivid deep blue comes from methane filtering out the red end of the spectrum. Even the difference between Uranus's pale blue-green and Neptune's rich blue turns out to be a story about atmospheric haze.The Doppler Twist Spectrometry doesn't just identify what worlds are made of — it can measure how they move. The same Doppler shift that changes an ambulance siren's pitch as it passes you also shifts light from a moving source. Scientists use this to measure a planet's rotation speed without watching it turn. More remarkably, this technique — Doppler spectroscopy — is how the first planet orbiting a sun-like star was confirmed in 1995, and how hundreds of exoplanets have been found since.Reading Atmospheres Across Light-Years Transit spectroscopy takes this further still: when an exoplanet crosses in front of its star, a sliver of starlight filters through the planet's atmosphere, picking up chemical fingerprints that survive the journey across hundreds of light-years to reach us. Scientists have already detected water vapor, carbon dioxide, and methane in distant exoplanet atmospheres. What researchers are ultimately searching for are biosignatures — chemical combinations that could only be explained by life. We haven't found them yet. But the tools are ready.Light is not just light. It's a message — and if you know how to read it, the universe opens up in ways a 19th-century philosopher could not have imagined. Next episode, we're bringing spectrometry back to Earth, where the same techniques are being used right now to track greenhouse gases, ozone, wildfire chemistry, and pollution plumes in real time.Jill’s Linkshttp://jillfromthenorthwoods.comhttps://www.buymeacoffee.com/smallstepspodTwitter - https://twitter.com/schmernYouTube @BuzzBlossomSqueakBy choosing to watch this video or listen to this podcast, you acknowledge that you are doing so of your own free will.

110 - How Light Reveals Secrets
What if you could know what something is made of — without ever touching it? That's not science fiction. It's spectrometry, and it's one of the most quietly extraordinary tools in all of science. In this first episode of a short series, we explore how light carries chemical fingerprints, what a high school flame test has in common with detecting helium on the sun, and why my dad's aircraft engine has everything to do with this story.🔑 The Oil Sample That Started It AllMilitary aircraft mechanics routinely send oil samples to labs to diagnose what's happening deep inside an engine — without taking it apart. The trace metals suspended in the oil tell exactly which component is wearing down. That's spectrometry in practice, and it's the same principle astronomers use to analyze distant planets.🔑 What Is Spectrometry?Every element interacts with light in its own unique way. When atoms are energized, their electrons release specific wavelengths of light — a fingerprint as distinctive as a bar code. Sodium glows bright yellow. Copper burns blue-green. Potassium turns pale violet. A spectrometer spreads those wavelengths apart and reads them precisely.🔑 The Flame Test — Science You've Probably SeenToss a pinch of table salt into a candle flame and it flashes vivid yellow — that's sodium's fingerprint made visible. Those colorful campfire packets that turn flames blue and purple and red? Metal salts: copper chloride, strontium, potassium. The fire is the instrument.🔑 Helium Was Discovered on the Sun FirstIn 1868, an astronomer running sunlight through a spectrometer during a solar eclipse found a yellow spectral line that matched no known element on Earth. Scientists named it helium — after Helios, the sun. For 27 years it was known only as a solar element. In 1895 it was finally identified here on Earth, same fingerprint, same element. Scientists identified it without ever leaving the planet.🔑 Where Else Spectrometry Shows UpFrom hospital blood analysis that can detect heavy metals at parts-per-billion concentrations, to food safety testing that can tell whether olive oil has been cut with a cheaper substitute, to environmental satellites tracking methane and ozone — the same principle is working everywhere. Every fingerprint tells a story.Next episode: how spectrometry lets us know exactly what planets are made of without sending a probe. The light tells us everything.Jill’s Linkshttp://jillfromthenorthwoods.comhttps://www.buymeacoffee.com/smallstepspodTwitter - https://twitter.com/schmernYouTube @BuzzBlossomSqueakBy choosing to watch this video or listen to this podcast, you acknowledge that you are doing so of your own free will.
