PLANET EARTH

Dig into deep time and glimpse geologic processes that form our planet and its habitable conditions. From the Big Bang onward, elements and atoms have been colliding, combining, transforming, and deteriorating, resulting in our current snapshot of the universe. In this program, explore evidence that reveals the story of this formation and clues to its inevitable disintegration. This month’s After Dark Online is a get-together to fall apart. As autumn sets in, trees become bare, and the northern hemisphere begins to chill, we’re exploring processes of decay, entropy, and how things come apart, making way for revisions and new arrangements. This event features: EARTH TIME with Dr. Marcia Bjornerud (begins at 3:26) Learn about the formation of our planet and what it means to live in geologic time. DECAY, with Odd Salon (begins at 37:08) In October, we're pleased to partner with Odd Salon for stories of entropy told through the annals of science, history, art, and adventure. Hosted by Kate O'Donnell, this week's program features: • FRANCES BASCOM: AMERICA'S FIRST LADY ROCKSTAR with Amy Widdowson (begins at 50:56) How hard work, determination, grit, and familial support helped one woman overcome fin de siècle gender barriers and re-write geologic time. • THE ANTHROPOCENE: DOES ARROGANCE OUTLAST DECAY? with Kit Rackley (begins at 1:05:26) Humans have been a ‘force of nature’ for only a few thousand years, depending on who you listen to. So it is arrogant to suggest a whole new geological epoch based on our actions? What human artifacts will be left after millions of years of decay? RESONANCE with Jorge Boehringer (begins at 1:16:55) Jorge Boehringer is a sound artist, noise fanatic, amp worshiper, music composer (for installations and ensembles or soloists with or without electronics [and/or computers] and/or for self as solo performer (viola, guitar, objects, percussion, voice, electronics, synthesizers). www.jorgeboehringer.com https://coreofthecoalman.bandcamp.com/ https://ongrowthandform.bandcamp.com/releases Notes on the Resonance: Elegy for the Sherbet Fleet By Jorge Boehringer For a long while now my work has focused on vague, ambiguous territory, trying to capture forms in their processes of coming into being or crossing over into perceptibility. I recently decided to try to focus this effort on single subjects and on processes that trace out their own existence in the world rather than mimic other phenomena or represent anything other than themselves. A great deal of the material I work with is collected from my everyday life. In collecting and re-presenting this, narratives weave themselves. There is a tension therefore between the narratives presented in my material and the raw presence I seek to set in process. Elegy for the Sherbet Fleet, a new piece of cinematic sound art, is to be viewed as a scene through a weather-beaten wooden window frame, as might be found along some abandoned seafront. Through this frame of nostalgia, perhaps something essential traces out its own existence, tells its story, and then disappears. Meanwhile, the wind sings a song through bones, within a circle of ancient timbers buried near Gore Point along the Norfolk Coast, UK. Something essential is there, out of time, but in reaching towards it, narratives stir themselves up like a salmon stirs up mud in a riverbed.

I love making videos about science with an unnatural level of enthusiasm. I like to focus on how we know things, not just what we know. And especially, the things we still don't know. If you've ever wondered about something in space and couldn't find an answer online - you can ask me! My day job is to do research into how supermassive black holes can affect the galaxies that they live in. In particular, I look at whether the energy output from the disk of material orbiting around a growing supermassive black hole can stop a galaxy from forming stars. http://drbecky.uk.com https://rebeccasmethurst.co.uk

We all know about Earth’s magnetic field, right? Well, Neil deGrasse Tyson and comic co-host Chuck Nice are here with another StarTalk Radio explainer to fill you in on the things you might not know about Earth’s magnetic field and magnetic poles. Find out why Earth’s south magnetic pole is actually in the North. We discuss how Earth’s magnetic field is not aligned with Earth’s rotation axis. You’ll discover why when you use a compass to find North it’s most likely pointing to somewhere in northwest Canada. You’ll learn about the differences between Earth’s magnetic poles vs. Earth’s geographic poles. Neil tells us how to actually find true North. Neil also explains why the magnetic poles of the Earth flip and have flipped many times. We discuss the “dynamo theory.” Lastly, we take a look at the Sun’s magnetic field and how that impacts sunspots. All that, plus, Neil tells us why there’s no understanding of magnetic fields without quantum physics.

It's well understood that from the surface of the Earth the curvature of the planet is not readily visible, but, as you travel higher the shape of the world becomes apparent to a casual glance. So I wanted to actually quantify this in an visual form using Youtube's 360 Video feature, it's obviously best experienced through a VR headset, or a 'Cardboard' style viewer, but you can also use the web browser if you just want to appreciate the visuals.

Hello wonderful person and welcome! My name is Anton and due to the 2020 housing crisis that's going on in some parts of the world, I ended up losing my apartment because the rent became too unbearable. As a result while I'm looking for a new place (probably 3-4 weeks or so), I made some pre-recorded long videos and a few other videos that will be posted daily. Hope you enjoy them and see you soon.

Launching aboard the joint U.S.-European Sentinel-6 Michael Freilich satellite is NASA’s next instrument that will help improve weather forecasting. The GNSS-RO (Global Navigation Satellite System Radio Occultation) instrument will make it easier for meteorologists to forecast further into the future with more accuracy, and aid in the protection of life and property with earlier warnings. The Sentinel-6 Michael Freilich satellite will launch from Vandenberg Air Force Base no earlier than November 10, 2020.

Earth’s magnetic field acts like a protective shield around the planet, repelling and trapping charged particles from the Sun. But over South America and the southern Atlantic Ocean, an unusually weak spot in the field – called the South Atlantic Anomaly, or SAA – allows these particles to dip closer to the surface than normal. Currently, the SAA creates no visible impacts on daily life on the surface. However, recent observations and forecasts show that the region is expanding westward and continuing to weaken in intensity. The South Atlantic Anomaly is also of interest to NASA’s Earth scientists who monitor the changes in magnetic strength there, both for how such changes affect Earth's atmosphere and as an indicator of what's happening to Earth's magnetic fields, deep inside the globe.

Join NASA ice experts as we discuss important science about Earth's icy regions, and how it can impact us here in warmer environments. NASA’s ICESat-2 mission uses a laser instrument on a satellite to precisely measure ice and just released new findings about how Earth’s ice is changing. Scientists discovered that enough ice has melted from Antarctica and Greenland to rise sea level about half an inch over the last 16 years. We’ll talk to these researchers to see what that means, and then take you to the coast of Virginia to see the real-world impacts of Earth's melting ice.

This animation depicts the triple star system HR 6819... where one of the three stars is a black hole. And not only that, at about 1000 light years distant it's the closest known black hole to Earth! The black hole is part of a binary, orbiting a star hotter and more massive than the Sun about once every 40 days (the black hole's orbital path is shown in red and the stars in teal). Farther out, another star orbits the pair, though how far out it is and how long the orbit takes isn't yet known. Calculations indicate the black hole has a mass 4 -6 times the mass of the Sun. It poses no threat to us. My blog post with a lot more info on this bizarre system: https://www.syfy.com/syfywire/astronomers-find-the-closest-known-black-hole-to-earth Credit: ESO/L.

Founded in 1970 by activist groups, Earth Day is now an annual, global event to raise awareness about our natural environment, the threats posed by a changing climate, and the actions we can take to address and mitigate the impacts of climate change on our communities. April 22, 2020, marks the 50th anniversary of Earth Day. Join us for an online program exploring some of the big ideas behind the science of the Earth’s systems. EARTH DAY: EXPLORING EARTH SCIENCE IN YOUR KITCHEN Staff environmental scientist Sue Pierre and staff teacher Lori Lambertson will start off with a discussion of the history of Earth Day. They will also share some activities you can do in and around your home to illustrate how Earth is a closed system for matter, but an open system for energy by exploring matter cycles, energy flows, and life webs. ENVIRONMENTAL BENEFITS OF SHELTERING IN PLACE Mary Miller, program director in the Exploratorium’s environment group, will chat with Ron Cohen from UC Berkeley about the change in carbon emissions since our sheltering in place began. We’ll check in on data from the air quality sensors that Ron’s lab has placed around the Bay Area, including two at the Exploratorium. This time of reduced traffic is an experiment in how much cutting back on gas-powered cars can help the environment! EXPONENTIAL GROWTH Join Exploratorium scientist Ron Hipschman for a discussion of exponential growth. Is growth always good? The biggest threat to our existence on planet Earth isn’t asteroids—it’s us. Learn about the exponential function and the conclusions we can draw from it.
