How Scientists Are Creating Diamonds From CO2 Emissions

A UK company is making synthetic diamonds from carbon that's sucked out of the air. But just how eco-friendly are these manufactured gems? » Subscribe to Seeker! http://bit.ly/subscribeseeker » Watch more Elements! http://bit.ly/ElementsPlaylist » Visit our shop at http://shop.seeker.com A UK company named Skydiamond hopes to revolutionize the traditional diamond mining industry by using carbon capture technology to do just that. The company calls it a ‘zero-impact diamond’ because the process pulls carbon dioxide right out of the air. Although, a diamond traps only a modest amount of carbon — one carat contains just 200 milligrams. Pure carbon can take many forms — it all depends on how the atoms are arranged. Graphite is arranged into multiple layers, graphene in a single layer, and if it’s rolled-up, it forms carbon nanotubes. But when each carbon forms 4 strong bonds in a tetrahedral structure, it becomes a diamond. Most natural diamonds were formed over a billion years ago, more than 120 kilometers beneath the Earth’s surface. This is where intense temperature and pressure cause carbon atoms to strongly bond together and arrange into crystal structures. Volcanic eruptions bring these crystals embedded in magma to the surface. When the magma cools, it hardens in long vertical shafts called kimberlite pipes. And these pipes are what's sought after in the mining industry. #co2 #emissions #diamonds #seeker #science #elements Read More: Eco-friendly diamonds made from the sky https://www.bbc.co.uk/newsround/54734306 "t took the team more than five years to get the technique right, ensuring they are physically and chemically identical to Earth-mined diamonds.

Scientists Want To 3D Print Bones in Your Body

For the first time ever, scientists have figured out a way to 3D print bones using living cells. A team at UNSW Sydney has developed a new technique that's taken us one step closer to directly 3D printing bones into a human body. » Subscribe to Seeker! http://bit.ly/subscribeseeker » Watch more Elements! http://bit.ly/ElementsPlaylist » Visit our shop at http://shop.seeker.com 3D printing has revolutionized our world, providing endless opportunities from printing homes, to even modeling organs. And now, scientists are tackling the challenge of incorporating living cells into bone-like structures using a new ceramic ink. This could one day allow surgeons to repair damaged bones by applying ink directly into the injury. Until now, if you needed a 3D printed bone it had to be premade in a lab somewhere, and the process involved using either high-temperature furnaces or toxic materials. Any living cells have to be added after the bone was printed. What’s cool about this new 3D printing technique is it eliminates the toxic chemicals and extreme heat by printing at room temperature with a unique new ink on demand and with live cells ready to grow. #3Dprinting #medicalresearch #science #seeker #elements Read More: 3D-Printing Resin for Dental Prosthetics Cleared by FDA https://www.plasticstoday.com/medical/3d-printing-resin-dental-prosthetics-cleared-fda Desktop Health announced today that it has received FDA 510(k) clearance for Flexcera Base, a proprietary resin for use in 3D printing high-quality dental prosthetics.

How to Trick Your Brain Into Breaking Bad Habits

Did you make a New Year's Resolution this year? Research shows that most people stop keeping up with these goals by February. Luckily, there are science-backed ways to break bad habits and form new healthy ones! » Subscribe to Seeker! http://bit.ly/subscribeseeker » Watch more Elements! http://bit.ly/ElementsPlaylist » Visit our shop at http://shop.seeker.com » Sign Up for Seeker's Newsletter! https://www.seeker.com/newsletters One strategy for breaking a bad habit is to make it harder to do. Psychologists call this increasing friction. If you’re constantly checking your phone, turn it over so you can’t see the screen, or put it in another room where it takes effort to get. At the center of every habit is a neurological pattern with 3 parts. First there’s a cue, or trigger, that tells your brain to go into auto-mode. Then there's the behavior, which is what we normally think of as the habit. The third step is the reward. Rewards cause your brain to release dopamine, a feel-good chemical that helps you remember the habit in the future. Let’s say you walk by the coffee shop everyday on your way to work.. triggering another craving for a cuppa joe and also lightening your bank account. You can avoid this habit by changing the environmental cue. Take a new route instead. But what makes a habit so easy to form in the first place? Functional MRI scans let researchers look into how brains respond to habitual and conscious tasks. The first time you do an action, brain activity in the prefrontal cortex and hippocampus lights up. This is where a lot of decision-making and planning happens. But when tasks get repeated, activity moves into more rudimentary areas of the brain, like the putamen and the basal ganglia. These primitive areas use up less energy because a bunch of related actions get grouped together, an idea known as “chunking.” This turns the behavior into a habit. #seeker #science #elements #badhabits #howto #advice Read More: Can Brain Science Help Us Break Bad Habits? https://www.newyorker.com/magazine/2019/10/28/can-brain-science-help-us-break-bad-habits In the modern era, habits have become a significant area of scientific inquiry. Psychologists have explored the genesis of habitual behavior and its impact on health and happiness. William James, echoing Aristotle, wrote, “All our life, so far as it has definite form, is but a mass of habits,—practical, emotional, and intellectual . . . bearing us irresistibly toward our destiny.” Distinctive brain pattern helps habits form https://news.mit.edu/2018/distinctive-brain-pattern-helps-habits-form-0208 MIT neuroscientists have now found that certain neurons in the brain are responsible for marking the beginning and end of these chunked units of behavior. These neurons, located in a brain region highly involved in habit formation, fire at the outset of a learned routine, go quiet while it is carried out, then fire again once the routine has ended. What Does It Really Take to Build a New Habit? https://hbr.org/2021/02/what-does-it-really-take-to-build-a-new-habit “There’s no such thing as 21 days to start a new habit,” Charles Duhigg, author of The Power of Habit, told me. “The amount of time it takes will vary from person to person.” Developing a pleasurable habit, like eating chocolate for breakfast, for instance, may take a day, while trying to exercise at 5 pm each evening may take much longer. ____________________ Elements is more than just a science show.

This Ocean Lab Is Uncovering the Mysterious Link Between Microbes and Climate

Studying marine aerosols in the field is extremely tricky, so scientists at the Scripps Institution of Oceanography have brought the complexity of the ocean—complete with real waves—into the lab. Check out The Swim, now streaming on Discovery+ http://bit.ly/dplus-yt » Subscribe to Seeker! http://bit.ly/subscribeseeker » Watch more Elements! http://bit.ly/ElementsPlaylist » Visit our shop at http://shop.seeker.com For decades, scientists have speculated that there is a link between ocean microbes, cloud formation, and ultimately, climate. But the logistics of studying marine microbes in their native environment is hard. So an ambitious team of scientists at UCSD is trying to crack that problem by bringing the ocean into the lab to study its biological, physical, and chemical complexity like never before. This “ocean-in-a-lab” at the Scripps Institution of Oceanography, is a 33-meter long pool that mimics the action of real waves. The tank is enclosed and clean air is pumped in over the channel, allowing the isolated study of aerosol spray and gases, which could include viruses, bacteria, and phytoplankton. The first way marine aerosols form is through sea spray. When waves break at the ocean’s surface, bubbles burst, and sea spray containing salt and all those little microbes go airborne. These marine aerosols can affect the formation of clouds over the ocean. They act as “seeds” that water vapor and ice can cling to, condensing into tiny droplets that can eventually become clouds. some types of aerosols can make clouds that are bright and white, cooling things down. So aerosols can have a really big impact on the temperature of the planet. It’s one of the reasons the ocean is known as the planet’s thermostat, because it plays a large role in regulating climate. #oceanlab #oceanography #cloudformation #climate #space #seeker #science #elements Read More: NSF Awards Scripps Oceanography $2.8 Million to Develop Advanced Ocean and Atmosphere Simulator https://scripps.ucsd.edu/news/national-science-foundation-awards-scripps-oceanography-28-million-develop-advanced-ocean-and "For project co-principal investigator Kim Prather, who directs the NSF Center for Aerosol Impacts on Chemistry of the Environment (CAICE) at UC San Diego, SOARS will enable more detailed study of aerosols, particles composed of sea salts, organic matter, viruses, and bacteria that are ejected from the ocean surface when waves break and winds blow."

Here’s why that matters https://www.pbs.org/wgbh/nova/article/200000-marine-viruses/ "Viruses are arguably the most successful biological entities in the sea, where they outnumber microbes—their typical hosts—10 to one. But scientists still have no idea what most of them do, or even how many genetically distinct populations of viruses may speckle the seas." ____________________ Elements is more than just a science show.

Does Zinc Actually Work to Fight the Flu and Cold?

Zinc: A wonder trace mineral for staving off the common cold? Or a totally overhyped home remedy? » Subscribe to Seeker! http://bit.ly/subscribeseeker » Watch more Elements! http://bit.ly/ElementsPlaylist » Visit our shop at http://shop.seeker.com Your body only needs tiny amounts, but it can still have big impacts on your health. Zinc is involved in hundreds of essential biological reactions in the body. It also aids in very important cellular processes like DNA replication, RNA transcription, and cell division. The human body doesn’t make zinc so we need to get it from our diets, particularly from foods like oysters, red meat, poultry, and beans, or from supplements. According to the U.S. Food and Nutrition Board, the daily recommended dietary allowance of zinc is 11 mg for men and 8 mg for women. When we don’t have these minute amounts of zinc, our bodies don’t work properly, so people who are zinc deficient are often treated with supplements. But the benefits for people with normal zinc levels has remained unclear. The efficacy of zinc supplements for treating the common cold has been debated as far back as the 70s, when researchers observed that zinc also inhibited viral replication. Armed with a better understanding of its role in immune function, people began to acknowledge zinc as an essential mineral for human health during this time. Interest grew even more after a 1984 study found that zinc lozenges may be useful for treating colds, but trials since then have yielded mixed results. But a meta-analysis submitted in November of 2020 might help close the gap of understanding zinc’s potential benefits. Researchers looked at 28 randomized controlled trials involving over 5,000 participants. They found that when zinc was taken to prevent respiratory infections, participants had a 28% lower risk of developing mild symptoms such those you’d get with the common cold—sneezes, sniffles, scratchy throat—and an 87% lower risk of developing moderately severe, flu-like symptoms, like a fever and all those aches and pains that make us feel lousy. If you already have a cold, using zinc to treat it was found to clear up symptoms two days earlier and reduce their severity at the peak of illness, but overall, you’re not in the clear, as they found that the day-to-day symptom severity remained the same. #zinc #health #seeker #science #elements Read More: Taking Zinc Can Shorten Your Cold.

Wild right?!? And if resurrecting a 6-ton creature that’s been extinct for about 4,000 years isn’t crazy enough, wait till you hear this…they’re hoping to enlist these shaggy creatures to help us solve a mammoth-sized problem. Mammoths were great ecosystem engineers. They knocked down trees and shrubs, making room for light colored grasses that reflected more sunlight than the darker trees, keeping ground temperatures cooler. In the winter, they trampled through the snow, exposing the ground to the arctic chill. By maintaining their grassland home, they also protected a perpetually-frozen layer of carbon-rich soil underneath, called permafrost. By the end of the last Ice Age though, most of the mammoths vanished, and the grasses of the steppe did too. We don’t know whether to point the finger at humans, climate, or some other cause, but what we do know is that the ecosystem changed significantly. #geneticengineering #crispr #cas9 #woollymammoths #Seeker #Elements Read More: AFTER 10,000 YEARS OF EXTINCTION, THIS IS WHEN WOOLLY MAMMOTHS WILL WALK THE EARTH AGAIN https://www.inverse.com/innovation/what-you-need-to-know-about-mammoth-de-extinction With starting capital of $15 million and four-to-six years of research, Lamm tells Inverse the company could produce a “herd” of woolly mammoths calves for the first time since the Ice Age.

What Would It Actually Take for Humans to Hibernate?

Suspended animation has the potential to transform everything from surgical medicine to deep space travel. So how close are researchers to making this a reality? » Subscribe to Seeker! http://bit.ly/subscribeseeker » Watch more Elements! http://bit.ly/ElementsPlaylist » Visit our shop at http://shop.seeker.com » Sign Up for Seeker's Newsletter! https://www.seeker.com/newsletters So, what would it take for humans to actually hibernate? To answer this, we first need to know why some animals hibernate in the first place. For warm-blooded animals, it can take a lot of energy to maintain a constant body temperature. That can be a really big challenge when their source of energy — food — is scarce. Hibernation is a survival mechanism that conserves energy by lowering the body’s core temperature, slowing the heart rate, and shifting into a lower metabolic state, known as torpor. For example, when arctic ground squirrels enter hibernation their temperature plummets from 37°C to -3°C and their metabolic rate drops by about 99%. Humans, however, are stuck with a relatively fixed body temperature of 37°C. Aside from minute variations, like when we sleep, our temperature only changes as a way to signal danger. Like when we’re sick, we get a fever. Just a few degrees off either way can mean death. But this isn’t a hard and fast rule. In 1999, a woman fell while skiing, crashing head first into a frozen stream. When medics arrived 80 minutes later, her body temperature had dropped to 13.7°C, rendering her clinically dead. But she miraculously survived! The extreme cold lowered her metabolism so her brain wasn’t oxygen starved. This can lead to permanent brain damage in a matter of minutes… usually not enough time to make it to the operating table. #seeker #science #elements #hibernation #humanbody Read More: You Could Probably Hibernate https://www.theatlantic.com/health/archive/2020/01/human-hibernation-real-possibility/605071/ "'It's very possible that humans could hibernate,' says Kelly Drew, a professor at the University of Alaska's Institute of Arctic Biology.

Auroras like the famous Northern Lights have captivated humans for millennia.

And we have finally proved just how these dazzling light shows happen. Auroras appear in the upper atmosphere near the poles and they first were mentioned in texts thousands of years ago. But it wasn’t until the late 1800’s that a Norweigian physicist first made the connection between electric currents in Earth’s magnetic field and auroras in the sky. And it’s only been since the beginning of the 20th century that scientists have known the basics of how auroras work. Today, we know that all auroras begin with solar activity. The sun puts out a continuous stream of charged particles called the solar wind. They’re responsible for producing the most intense auroras. They disrupt the magnetic field lines, creating ripples that rebound back toward Earth known as Alfven waves.

The Surprising Reason Why You Talk in Your Sleep

Some of us sleep soundly without uttering a whisper; others deliver entire speeches while sawing their logs. But why is that...and how does sleep talking affect our health? » Subscribe to Seeker! http://bit.ly/subscribeseeker » Watch more Elements! http://bit.ly/ElementsPlaylist » Visit our shop at http://shop.seeker.com Many people think of sleep as the brain shutting off. Curtains. Lights out. But our brains are actually quite active during slumber. Throughout the night, we cycle through two types of sleep: Rapid Eye Movement, or REM, and non-REM, which has three stages. As we move through each stage, our brain waves progressively fall into lower frequencies and higher amplitudes until we reach deep, slow-wave sleep at stage 3. Sleep talk can happen at any point during what scientists call “transitory arousal”, which is when a sleeper becomes half awake while transitioning from one stage to the next. Interestingly, the quality of our speech here decreases as we move closer toward stage 3. After stage 3 we enter REM sleep. This is when our eyes rapidly move behind closed lids and our brain activity becomes closer to how it is when we're awake. There are two different structures in the brain that control when we’re awake and when we’re asleep, sort of like a light switch. One is the Reticular Activating System, or RAS, a complex network of neurons located in the brain stem. It releases chemical messengers called neurotransmitters that promote wakefulness and help regulate our sleep-wake cycles. The other system, the Ventrolateral Preoptic Nucleus, or VLPO, is located in the hypothalamus. It releases neurotransmitters that bring on sleep by suppressing neural activity to the RAS. During REM, the VLPO structure releases powerful neurotransmitters that work together to inhibit motor neurons and prevent you from acting out your dreams of flying. #science #seeker #REM #sleep #health Read More: Is There a Link Between Sleepwalking, Sleep Talking, and Mental Health? https://www.goodtherapy.org/blog/is-there-a-link-between-sleepwalking-sleep-talking-and-mental-health-1103187 "Both sleepwalking and sleep talking can happen for many reasons.

What Really Killed the Dinosaurs?

One of science's biggest mysteries — what caused the dinosaurs to go extinct — may have finally been put to rest. » Subscribe to Seeker! http://bit.ly/subscribeseeker » Watch more Elements! http://bit.ly/ElementsPlaylist » Visit our shop at http://shop.seeker.com Thanks to this recently published study in Science, we might have finally learned the truth behind what really killed dinosaurs once and for all. It’s been told that an asteroid more than 10-kilometers across slammed into the Yucatan Peninsula, putting an end to the dinosaur's long reign. But the actual ‘cause of death’ has been the center of a decades-long raging controversy. Many scientists have argued for alternative theories to explain what brought on the dinosaur’s final days, including cosmic rays, an outbreak of disease, or as we previously reported, an inferno of blazing wildfires. But aside from the asteroid, there is another competing theory involving massive volcanic eruptions that happened around the same time, leading to some confusion over which is the actual culprit. Find out more about how this newfound research could provide a definitive timeline that could likely end the decades-old argument in this Elements. #dinosaurs #bigbangtheory #volcanoes #science #seeker #elements Read More: Asteroid impact, not volcanic eruptions, killed the dinosaurs https://www.ucl.ac.uk/news/2020/jan/asteroid-impact-not-volcanic-eruptions-killed-dinosaurs "In a Yale-led study, published today in Science, analysis of marine fossils and climate models shows that the major release of volcanic gasses, thought by some to contribute to the extinction, happened about 200,000 years before the asteroid impact, making the asteroid the sole driver of the extinction event." The Nastiest Feud in Science https://www.theatlantic.com/magazine/archive/2018/09/dinosaur-extinction-debate/565769/ "Before the asteroid hypothesis took hold, researchers had proposed other, similarly bizarre explanations for the dinosaurs’ demise: gluttony, protracted food poisoning, terminal chastity, acute stupidity, even Paleo-weltschmerz—death by boredom." How an asteroid ended the age of the dinosaurs https://www.nhm.ac.uk/discover/how-an-asteroid-caused-extinction-of-dinosaurs.html "Around 75% of Earth's animals, including dinosaurs, suddenly died out at the same point in time.

Did Scientists REALLY Find Signs of Life on Venus?

Generally considered inhabitable, new observations suggest that Venus could in fact be harboring life. Where? In its clouds. » Subscribe to Seeker! http://bit.ly/subscribeseeker » Watch more Elements! http://bit.ly/ElementsPlaylist » Visit our shop at http://shop.seeker.com After earning a bad reputation as Earth’s “evil twin,” Venus is finally getting some good press. Recently, a team of international astronomers announced the discovery of a rare gas called phosphine in the planet’s atmosphere, leaving some to believe it might be a sign of potential life on the seemingly inhabitable planet. With Venus' surface reaching a temperature hot enough to melt lead; its crushing air pressure; and its ultra-dense clouds made up mostly of corrosive sulfuric acid, it’s no wonder that the search for life has been focused on Mars. But in June 2017, astronomers made a surprising find while examining data captured by the James Clerk Maxwell Telescope in Hawaii. Radio telescopes like this take advantage of the fact that atoms and molecules absorb and emit specific frequencies, leaving “fingerprints” that can be used to identify chemical compounds over astronomical distances. And a tell-tale dip in the spectrum showed that phosphine, a pyramid-shaped molecule considered by some scientists as a potential biomarker, meaning that it could hint at the presence of life, was somehow present in the upper clouds of Venus. Phosphine is more commonly expected to be found on Earth. In 2019, the ALMA telescope confirmed the findings, revealing roughly 20 parts per billion of phosphine. While this discovery is exciting, we still need more data in order to confirm whether or not Venus is a potential candidate for life.

What Is Phosphine and Why Does It Point to Extra-Terrestrial Life Floating in the Clouds of Venus? https://scitechdaily.com/what-is-phosphine-and-why-does-it-point-to-extra-terrestrial-life-floating-in-the-clouds-of-venus/ "To create the observed quantity of phosphine (which consists of hydrogen and phosphorus) on Venus, terrestrial organisms would only need to work at about 10% of their maximum productivity, according to the team." Is There Life on Venus? These Missions Could Find It https://www.scientificamerican.com/article/is-there-life-on-venus-these-missions-could-find-it/ "The reality is that the puzzle of Venusian phosphine will remain unsolved until several critical pieces of information are in hand, says Kandi Jessup, a senior research scientist at the Southwest Research Institute (SwRI)." ____________________ Elements is more than just a science show.

The First Full-Size 3D Print of a Human Heart Is Here

Imagine having the option to get a 3D-printed organ. Well, a team of biomedical engineers from Carnegie Mellon University has just developed the first flexible, full-size, 3D-print of a human heart, bringing us one step closer to that reality. » Subscribe to Seeker! http://bit.ly/subscribeseeker » Watch more Elements! http://bit.ly/ElementsPlaylist » Visit our shop at http://shop.seeker.com Additive manufacturing printers are popular, but are typically known to build hard objects using materials like plastic or metal. But rigid plastic organs aren’t very practical. These printers could be used with softer materials, like biological hydrogels -- you know, to make a heart -- but those tend to collapse mid-print. But this new method can change the game.The 3D-printing technique is called Freeform Reversible Embedding of Suspended Hydrogels or FRESH. It can print biological structures with soft squishy materials like alginate, a biomaterial made from seaweed, which feels like human tissue. AND it cleverly solves that collapsing problem during print by suspending flexible materials inside a container of gelatin. For this team of researchers it all starts with a MRI scan from a real heart. The scan gets “chopped-up” digitally into horizontal slices by a program which then translates them into code that a printer will understand. A needle-like nozzle moves through the gelatin support bath, extruding thin layers of alginate. The layers stack on top of each other to build the shape. When the print is complete, it’s put in an incubator overnight, where the temperature is raised to 37°C to gently melt away the gelatin support structure, leaving only the 3D-printed heart. #3dprinting human heart #health #technology #science #seeker #elements Read More: 3D bioprinted heart provides new tool for surgeons https://engineering.cmu.edu/news-events/news/2020/11/18-3d-printed-heart.html "Adam Feinberg and his team have created the first full-size 3D bioprinted human heart model using their Freeform Reversible Embedding of Suspended Hydrogels (FRESH) technique."

The Mystery of Saturn’s Giant Hexagonal Storm May Soon Be Solved

Saturn’s hexagonal storm has been raging for decades for reasons unknown… until now. » Subscribe to Seeker! http://bit.ly/subscribeseeker » Watch more Elements! http://bit.ly/ElementsPlaylist » Visit our shop at http://shop.seeker.com Saturn has a giant 18,000-mile, hexagon-shaped cloud storm that could comfortably fit two Earths inside it, and since its discovery, the mysterious hexagon has left scientists stumped. Until now. A recent computer simulation designed by Harvard researchers might provide some clues about what exactly is forming this unusual hexagon marvel. The high-speed, six-sided jet stream was first discovered in the early 1980’s by NASA’s Voyager flybys. Using data taken during Cassini’s 13-year mission, researchers from Harvard set out to answer how Saturn’s turbulent conditions could give rise to stable, geometric jets. The team of researchers built a 3-D computer simulation of Saturn’s hexagon to study its behavior.

Could Ocean Cleanup’s New Interceptor Help Solve Our Plastic Problem?

The Ocean Cleanup just released a new device to help clean up plastic in rivers before it reaches the ocean. So how does it work? » Subscribe to Seeker!http://bit.ly/subscribeseeker » Watch more Elements! http://bit.ly/ElementsPlaylist Every year we produce roughly 300 million metric tons of plastic globally, and these plastics can end up in oceans, rivers, and eventually our food chain. When a piece of plastic finds its way into the ocean, exposure to sunlight and the elements work to break it down into smaller and smaller fragments. Marine animals often mistake plastic trash for food, which can lead to malnutrition and a potential build-up of toxic chemicals in their bodies. And since humans are a part of the food chain, plastics find their way into our bodies, too. The Ocean Cleanup says that its new suite of technologies can help address this growing problem, the group’s primary goal is to clean up the Great Pacific Garbage Patch, the world's largest accumulation zone containing more than 1.8 trillion pieces of plastic. Find out more about The Ocean Cleanup’s new tech and how it is cleaning Earth’s waters and working to prevent new plastics from entering the oceans on this episode of Elements. #Oceans #PlasticPollution #NewTech #Climate #Environment #Seeker #Elements #Science The Great Pacific Garbage Patch Is Not What You Think It Is | The Swim - https://youtu.be/6HBtl4sHTqU ____________________ Read More: THE OCEAN CLEANUP UNVEILS PLAN TO ADDRESS THE MAIN SOURCE OF OCEAN PLASTIC POLLUTION: RIVERS https://theoceancleanup.com/updates/the-ocean-cleanup-unveils-plan-to-address-the-main-source-of-ocean-plastic-pollution-rivers/ "The Ocean Cleanup aims to tackle the 1,000 most polluting rivers, responsible for about 80% of ocean plastic pollution, before the end of 2025."

Forget GPS, Future Missions May Use Neutron Stars to Navigate Deep Space

Lighthouses have helped safely guide mariners for centuries. As space explorers consider traveling to far-flung destinations, could pulsars provide them with similar guidance? » Subscribe to Seeker! http://bit.ly/subscribeseeker » Watch more Elements! http://bit.ly/ElementsPlaylist » Visit our shop at http://shop.seeker.com As NASA sets its sights on distant planets, astronauts will need a way of orienting themselves in space. Here on Earth, we use the satellite-based GPS that carry atomic clocks that provide extremely accurate time, which gets used by your phone or car to help calculate your position. And while GPS works just fine if you’re on Earth or close to it, the signal weakens once you go beyond its range. Historically, NASA has primarily used the Deep Space Network to track missions beyond Earth’s orbit. The three ground stations are approximately 120 degrees apart, and they beam up radio waves to a spacecraft and log details as the signals return. Navigation data is calculated on Earth and sent back, helping ground control keep missions on the right path. But if that radio link with Earth is lost, a spacecraft can find itself adrift. And so we need a better solution, like if a spacecraft could navigate independently, without ground control. Enter: Pulsars. Find out how neutron stars, pulsars, and a piece of equipment called the Neutron Star Interior Composition Explorer, or NICER, can help spacefaring explorers navigate space more effectively in this Elements. #spaceexploration #NASA #astronauts #GPS #space #science #seeker #elements Read More: Future Space Travelers May Follow Cosmic Lighthouses https://www.nasa.gov/mission_pages/station/research/news/future-space-travelers-may-follow-cosmic-lighthouses-sextant-results "An X-ray telescope on the exterior of the space station, the Neutron star Interior Composition Explorer or NICER, collects and timestamps the arrival of X-ray light from neutron stars across the sky."
