Relax and breathe along with Julie Potiker as she leads you through this healing breath meditation. She completes the meditation with her poem, "In the Habitable Zone".In the Habitable Zone, by Julie PotikerI let the thought settle—dew on my skin—120 light years from my morning coffee,a world, more than eight times biggerthan Earth, orbits a red dwarf star.Spinning steadily in what scientists callthe habitable zone.It could be a Hycean world, coveredin water so deep it forgets land.And maybe, just maybe, tiny beingsfloat there like Earth planktonreleasing dimethyl sulfide intoan atmosphere the stirs with methane,each molecule , a question flung towardus by the James Webb's patient lens.Science says: 99.7 percent confidence.Still, let's be careful. There are otherpaths that mimic life. But I want to exhalewonder. Let awe arise like phytoplanktonbasking in the sun. If the universe speaksin more than one place how can we notlisten with our whole hearts. Maybe, justmaybe, we are not aloneafter all.-In the Habitable Zone, by Julie Potiker.Find out more about using mindfulness in everyday life through Julie's books, "SNAP: From Calm to Chaos", and "Life Falls Apart, But You Don't have To: Mindful Methods for Staying Calm in the Midst of Chaos".

How would we know if life was on another planet?

Astronomers have just found a planet that might be perfect for human life! It's in the “Goldilocks zone,” meaning it's not too hot or too cold—just right for liquid water. Scientists believe this planet could have an atmosphere, oceans, and maybe even life already. It's way out in space, but with new technology, we might learn more about it soon. Imagine a future where humans could travel there and start a new home among the stars! For now, all we can do is keep exploring and dreaming about what's out there.

We're experimenting and would love to hear from you!In this episode of 'Discover Daily', we explore groundbreaking developments in AI, cryptocurrency regulation, and early universe water formation. AI startup Anthropic has reached a staggering $61.5 billion valuation after closing a $3.5 billion funding round, showcasing impressive growth with an annual recurring revenue of $800 million. The company's latest AI model, Claude 3.7 Sonnet, introduces innovative 'hybrid reasoning' capabilities, pushing the boundaries of artificial intelligence.The U.S. Securities and Exchange Commission has made a landmark decision, declaring that meme coins generally do not constitute securities under federal law. This significant shift in cryptocurrency regulation has far-reaching implications for the industry, though it comes with important caveats and has sparked debate among regulators.Our main story delves into a revolutionary study published in Nature Astronomy, suggesting that water may have first formed in the universe just 100 to 200 million years after the Big Bang. This discovery challenges our understanding of cosmic evolution and implies that conditions for life may have existed far earlier than previously thought. The research opens up exciting new avenues for investigating the potential for early habitable environments and the emergence of life in the universe.From Perplexity's Discover Feed:https://www.perplexity.ai/page/anthropic-reaches-61-5b-valuat-goxeBd89TI6.SXIGLTUGUQ https://www.perplexity.ai/page/sec-says-meme-coins-are-not-se-yn4ZON0XRmyFivwgjKtRuQhttps://www.perplexity.ai/page/early-universe-may-have-had-wa-fUgTawHmSWGvtriYXLndsA**Introducing Perplexity Deep Research:**https://www.perplexity.ai/hub/blog/introducing-perplexity-deep-research Perplexity is the fastest and most powerful way to search the web.

Earth lies in the middle of the Sun’s habitable zone. That’s the distance from the Sun where conditions are most comfortable for life. And astronomers are concentrating their hunt for life in other star systems in their habitable zones. There’s an idea that galaxies have habitable zones as well. The zones would have a good mix of chemical elements, not too much radiation, and a low risk of exploding stars. Stars consist mainly of hydrogen and helium. But to make planets like Earth, you need a good supply of heavier elements — things like oxygen, silicon, and iron. Those elements are forged in the hearts of stars, then blown out into space when the stars die. So to have good conditions for life, you need a region where lots of dead stars have “seeded” the galaxy with heavy elements. But you don’t want to be too close to stars that die in massive explosions. They can damage a planet’s atmosphere, exposing life to high levels of radiation. So you want to be away from a galaxy’s core, where stars are packed close together — including ones that might explode. The cores of most galaxies also harbor supermassive black holes. As they pull in stars and gas they produce lots of radiation, saturating the space around them. So in our home galaxy, the Milky Way, you want to be away from the core, but not too far away. And that’s just where Earth is — about half way from the center to the edge — in the galactic habitable zone. Script by Damond Benningfield

Goldilocks in UV.

Author and book designer Rebecca Demarest will be featured on this episode of SETI Live, along with astronomer and SETI Research Scientist Paul Dalba. The two will delve into the upcoming Exotopia expedition, an experimental sci-fi narrative that invites participants to embark on imaginary journeys to study extraterrestrial life on actual exoplanets within our galaxy. The forthcoming voyage will transport us to TOI-1452 b, a super-Earth exoplanet situated roughly 100 lightyears from Earth. TOI-1452 b orbits a red dwarf star within its Habitable Zone, an area where there is a possibility of liquid water on the planet's surface, given the presence of a protective atmosphere. Although scientists have some understanding of TOI-1452 b's characteristics, there is still a great deal of uncertainty surrounding this newly discovered world. The Exotopia expedition will explore this enigma and offer travelers the opportunity to illustrate their own adventure using AI-generated art. Join us as we discuss the unique confluence of astronomy, art, sci-fi, and AI technology related to this distinctive storytelling experience.

A Catalog of Habitable Zone Exoplanets by Michelle L. Hill et al. on Monday 17 October The search for habitable planets has revealed many planets that can vary greatly from an Earth analog environment. These include highly eccentric orbits, giant planets, different bulk densities, relatively active stars, and evolved stars. This work catalogs all planets found to reside in the HZ and provides HZ boundaries, orbit characterization, and the potential for spectroscopic follow-up observations. Demographics of the HZ planets are compared with a full catalog of exoplanets. Extreme planets within the HZ are highlighted, and how their unique properties may affect their potential habitability. Kepler-296 f is the most eccentric

The Sun is both a natural laboratory for plasma physics and the focus of the field of study known as Heliophysics. Heliophysics involves the physics of how the Sun actually works. Dr. Michael Kirk, P.I. of the NASA Heliophysics Education Activation Team, defines the state of matter known as plasma, and explains how studying the Sun helps us better understand satellites, radio signals, GPS signals, and many other technologies that affect our life every day. Solar eclipses, including the upcoming annular solar eclipse (October 2023) and total solar eclipse (April 2024), are also discussed.        NASA HEAT Homepage https://science.nasa.gov/science-activation-team/nasa-heliophysics-education-activation-team    NASA Eclipses Home https://solarsystem.nasa.gov/eclipses/home/ 

Lightning-induced chemistry on tidally-locked Earth-like exoplanets by Marrick Braam et al. on Monday 26 September Determining the habitability and interpreting atmospheric spectra of exoplanets requires understanding their atmospheric physics and chemistry. We use a 3-D Coupled Climate-Chemistry Model, the Met Office Unified Model with the UK Chemistry and Aerosols framework, to study the emergence of lightning and its chemical impact on tidally-locked Earth-like exoplanets. We simulate the atmosphere of Proxima Centauri b orbiting in the Habitable Zone of its M-dwarf star, but the results apply to similar M-dwarf orbiting planets. Our chemical network includes the Chapman ozone reactions and hydrogen oxide (HO$_{mathrm{x}}$=H+OH+HO$_2$) and nitrogen oxide (NO$_{mathrm{x}}$=NO+NO$_2$) catalytic cycles. We find that photochemistry driven by stellar radiation (177-850 nm) supports a global ozone layer between 20-50 km. We parameterise lightning flashes as a function of cloud-top height and the resulting production of nitric oxide (NO) from the thermal decomposition of N$_2$ and O$_2$. Rapid dayside convection over and around the substellar point results in lightning flash rates of up to 0.16 flashes km$^{-2}$yr$^{-1}$, enriching the dayside atmosphere below altitudes of 20 km in NO$_{mathrm{x}}$. Changes in dayside ozone are determined mainly by UV irradiance and the HO$_{mathrm{x}}$ catalytic cycle. ~45% of the planetary dayside surface remains at habitable temperatures (T$_{mathrm{surf}}$>273.15 K) and the ozone layer reduces surface UV radiation levels to 15%. Dayside-nightside thermal gradients result in strong winds that subsequently advect NO$_{mathrm{x}}$ towards the nightside, where the absence of photochemistry allows NO$_{mathrm{x}}$ chemistry to involve reservoir species. Our study also emphasizes the need for accurate UV stellar spectra to understand the atmospheric chemistry of exoplanets. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2209.12502v1

Hot Earth or Young Venus? A nearby transiting rocky planet mystery by L. Kaltenegger et al. on Wednesday 07 September Venus and Earth provide an astonishingly different view of the evolution of a rocky planet, raising the question of why these two rocky worlds evolved so differently. The recently discovered transiting rocky planet LP 890-9c (TOI-4306c, SPECULOOS-2c) is a key to this question. SPECULOOS-2c (1.367 +0.055 -0.039 R_Earth) circles a relatively low-activity nearby (32 pc) M6V star in 8.46 days. SPECULOOS-2c receives 0.906 +/- 0.026 of the flux of modern Earth, putting it very close to the inner edge of the conservative Habitable Zone, where models differ strongly in their prediction of how long Earth-like planets can hold onto their water. Our atmosphere models show that the transmission spectra of the observable species can tell the difference between a hot, wet Young Earth, a steamy rocky planet caught in a runaway greenhouse at the brink of complete water loss, and a Venus-analog. Distinguishing these scenarios from the planet's spectra will provide critical new insights into when a hot terrestrial planet loses its water and becomes a Venus. SPECULOOS-2c is a prime target for observations with JWST. Observing it will also provide key insights to predict the long-term future of Earth. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2209.03105v1

Life on Exoplanets In the Habitable Zone of M-Dwarfs? by Anna C. Childs et al. on Wednesday 07 September Exoplanets orbiting in the habitable zone around M-dwarf stars have been prime targets in the search for life due to the long lifetimes of the host star, the prominence of such stars in the galaxy, and the apparent excess of terrestrial planets found around M-dwarfs. However, the heightened stellar activity of M-dwarfs and the often tidally locked planets in these systems have raised questions about the habitability of these planets. In this letter we examine another significant challenge that may exist: these systems seem to lack the architecture necessary to deliver asteroids to the habitable terrestrial planets, and asteroid impacts may play a crucial role in the origin of life. The most widely accepted mechanism for producing a stable asteroid belt and the late stage delivery of asteroids after gas disk dissipation requires a giant planet exterior to the snow line radius. We show that none of the observed systems with planets in the habitable zone of their star also contain a giant planet and therefore are unlikely to have stable asteroid belts. We consider the locations of observed giant planets relative to the snow line radius as a function of stellar mass and find that there is a population of giant planets outside of the snow line radius around M-dwarfs. Therefore, asteroid belt formation around M-dwarfs is generally possible. However, we find that multi-planetary system architectures around M-dwarfs can be quite different from those around more massive stars. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2209.02860v1

However, the heightened stellar activity of M-dwarfs and the often tidally locked planets in these systems have raised questions about the habitability of these planets. In this letter we examine another significant challenge that may exist: these systems seem to lack the architecture necessary to deliver asteroids to the habitable terrestrial planets, and asteroid impacts may play a crucial role in the origin of life. The most widely accepted mechanism for producing a stable asteroid belt and the late stage delivery of asteroids after gas disk dissipation requires a giant planet exterior to the snow line radius. We show that none of the observed systems with planets in the habitable zone of their star also contain a giant planet and therefore are unlikely to have stable asteroid belts. We consider the locations of observed giant planets relative to the snow line radius as a function of stellar mass and find that there is a population of giant planets outside of the snow line radius around M-dwarfs. Therefore, asteroid belt formation around M-dwarfs is generally possible. However, we find that multi-planetary system architectures around M-dwarfs can be quite different from those around more massive stars. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2209.02860v1

Not all bacterial cells replicate themselves by the same process – the usual ‘cell division' into two cells of equal size. Some, by contrast, do so by means of a process called ‘sporulation', in which the cell divides into ‘mother' and ‘daughter' cells, with the former containing and nourishing the latter until it's ready to be released into the world. Jonathan speaks with the Slovak Academy of Science's Imrich Barák – a molecular biologist and finalist for the 2021 ESET Science Award – about his research into this fascinating process of bacterial reproduction. – Repeat: The discovery that some of the moons of the larger planets in our solar system have liquid water under the surface, and hence the potential to support life, came as a big surpise to scientists. The question then was, where did these moons, far outside the solar system's so-called “habitable zone”, get their warmth? Jonathan speaks with astrobiologist Tomas Paulech about just this question.

Welcome back to The Backrooms 101, in this episode we explain the 2nd level of The Backrooms, "The Habitable Zone." Join me for the ride as we no-clip into level 1 of The Backrooms!

On this ID the Future from the vault, host Jay Richards and astronomer Guillermo Gonzalez, authors of The Privileged Planet: How Our Place in the Cosmos Is Designed for Discovery, discuss what's changed in the years since the book first appeared. One big change: the number of exo-planets discovered has exploded from 200 or so to several thousand. Gonzalez walks through this and other exciting recent advances in astronomy, and the two discuss how these new discoveries bear on the predictions and arguments they advanced in their book. Also in the discussion, Gonzalez speculates about what the James Webb space telescope may uncover after it comes online. Source

How come there is an ocean on Jupiter's moon, Europa? Jupiter after all is five times further away than the Earth is from the Sun. It is not even close to the Habitable Zone. And yet, there is liquid water ocean there. In fact, the four large moons of Jupiter (Io, Europa, Ganymede, and Callisto) are all fascinating places. Please join astrophysicist Salman Hameed in exploring the reasons why there is a liquid water ocean on Europa. Full video of this podcast is here: https://youtu.be/J_Fp3pPdDsU

In this episode we'll be discussing the many details and characteristics of "The Habitable Zone, and the many survival tips you can use to over come what's within. Make sure you've brought a flashlight because we're no clipping into Level One!

The discovery that some of the moons of the larger planets in our solar system have liquid water under the surface, and hence the potential to support life, came as a big surpise to scientists, as these moons were far outside the so-called “habitable zone” – the region nearer the sun containing Earth and Mars, and previously believed to be the only region capable of supporting life. The question then was, where did these moons get their warmth? Jonathan speaks with astrobiologist Tomas Paulech about just this question.

Astronomers have discovered thousands of exoplanets, and still need to confirm thousands more. And over the coming decades, we'll probably learn of millions of planets, orbiting stars we've never heard of. That's why it's reassuring to know astronomers are learning a tremendous amount about the closest star system to our own, Proxima Centauri. In fact, we now know of two planets orbiting the red dwarf star, one of which is in the habitable zone. Thumbnail credit: NASA/Harvard-Smithsonian Center for Astrophysics/D.

K2-18b, also known as EPIC 201912552 b, is an exoplanet orbiting the red dwarf K2-18, located 124 light-years (38 pc) away from Earth. The planet, initially discovered through the Kepler space telescope, is about eight times the mass of Earth, and thus is classified as a super Earth. It has a 33-day orbit within the star's habitable zone. In 2019, two independent research studies, combining data from the Kepler space telescope, the Spitzer Space Telescope, and the Hubble Space Telescope, concluded that there are significant amounts of water vapor in its atmosphere, a first for a planet in the habitable zone.

As astronomers hunt for habitable, Earth-like worlds, one popular place to look is around M stars, a type of red dwarf. Couple reasons for that:"First of all most of the stars in our galaxy are like that." Eike Guenther is an astronomer at the Thüringer State Observatory in Germany. "And secondly the closest stars to us are like this. And thirdly, it's relatively easy to find planets around them which have a low mass or small diameter."M stars are smaller and fainter than our Sun. Meaning the zone around them where liquid water could exist—the habitable zone—is really close in. And in that region around the star it's also easier to spot small exoplanets, with current techniques.A few months back, Guenther had his telescope trained on an M star 16 light-years away, known as AD Leonis, when he spotted a huge stellar flare. A Neptune-sized giant exoplanet lurking around the star appears to have survived unscathed. But the event inspired Guenther and his team to ask how that huge flare would have affected a hypothetical Earth-sized exoplanet orbiting the star. So they ran a computer simulation.The result? The shower of X-rays, thousands of times stronger than what the Sun unleashes on the Earth, would have blasted away much of the imaginary exoplanet's protective ozone. And multiple such flare events would be disastrous for life as we know it."So this analog, of taking the Earth, and saying, 'Ok, we put it in the habitable zone, and that's how a habitable planet looks like'—that's presumably wrong. One now has to consider these very energetic events that change the properties of the atmospheres of the other planets."He presented the observations at the recent European Week of Astronomy and Space Science conference in Liverpool. [Eike Guenther, Flares and CMEs in M-stars]Guenther says, if anything, this finding makes the weird planets hugging M-stars even more intriguing, in terms of planetary diversity. "I would say… keep looking!"NASA's Transiting Exoplanet Survey Satellite, or TESS, is set to launch April 16th… if all goes well… it'll soon be looking too.—Christopher Intagliata[The above text is a transcript of this podcast.]
