So, redistributing Earth's surface weight re-orientates its spin axis, whether that be through damming water, melting glaciers, or groundwater removal.But it's only Earth's outer crust floating over its gooey inner parts – not the inner goo generating the magnetic field – that shift, leading to a different part of Earth's surface sitting over our planet's inner magnetic north.So, while north itself hasn't really moved in space, Earth's surface has shifted around, over the top of it. This phenomenon is called true polar wander.https://www.sciencealert.com/earths-flipping-magnetic-field-heard-as-a-sound-is-an-unnerving-horror———PlastikThe primary source of plastic isfossil fuels, specifically crude oil and natural gas.

What happens when a planet is full of water—but too hot for oceans? Meet the "steam worlds," exotic exoplanets wrapped in thick water vapor and boiling at thousands of degrees. These strange worlds may be far from habitable, but they're reshaping how scientists think about planets, water, and where life might exist. In this episode of SETI Live, host Beth Johnson talks with Artem Aguichine of the University of California, Santa Cruz, about his new research modeling the interiors and atmospheres of steam worlds—a class of water-rich sub-Neptunes that could dominate our galaxy. With data from the JWST revealing steam signatures on distant planets, these models are helping scientists decode what's really going on beneath the haze. Join us as we explore: • What defines a "steam world" and how it forms • How water behaves under crushing pressure and searing heat • Why JWST's new observations are changing the game • What these discoveries mean for the future search for life beyond Earth

We might be surrounded by tiny, rhino-mass black holes. The James Webb Space Telescope (JWST) has just spotted two black holes that could unlock one of cosmology's biggest puzzles: how supermassive black holes formed so quickly in the early universe. This discovery challenges our understanding of black hole formation, and suggests primordial black holes could be more common than we thought, maybe even lurking all around us.

Kristian Harloff:  The cosmos just got a lot weirder—or did it? Interstellar comet 3I/ATLAS (aka "Three Eye Atlas") has been streaking through our solar system since its discovery in July 2025, sparking wild debates: Is this just a cosmic snowball, or something far more exotic? NASA insists it's a natural comet, releasing stunning new images this week showing its fuzzy coma and tail—no aliens in sight.  But not everyone's buying it. Enter Rep. Tim Burchett (R-TN), the UFO disclosure advocate who's been vocal about government cover-ups. In a recent tweet, Burchett doubled down on the fringe theories, declaring 3I/ATLAS "isn't a comet or anything we can explain with current science."  Is he hinting at alien tech, like a probe from another star system? Or even tying it to his claims of underwater alien bases?  The speculation is exploding online—from Harvard's Avi Loeb suggesting a 40% chance it's non-human  to viral videos claiming it's "under alien control."  In this episode of Down to Earth with Kristian Harloff, I break it all down: •  NASA's latest HiRISE and JWST images—do they really debunk the extraterrestrial hype?   •  Burchett's tweet: What does "unexplainable" really mean in the age of UAP hearings? •  The science vs. the sensational: Radio signals from the comet? Color changes? Acceleration anomalies that have NASA scrambling?  •  My take: As an average Joe diving into UAP news, is 3I/ATLAS the smoking gun we've been waiting for, or just interstellar clickbait? Whether you're Team Comet or Team Cosmic Cover-Up, this visitor from the stars (slated to swing by Earth safely on Dec 19 at 267 million km away ) demands a closer look. Hit play and let's unpack the mystery! Kristian Harloff:  The cosmos just got a lot weirder—or did it?

Recently we heard a lot about hyaena planets. They are supposed to be sub-neptunes with thick Hydrogen atmosphere which allows them to maintain a planet-wide liquid ocean in a vast range of conditions. The most famous example of such a planet is K2-18b which was recently observed by JWST. But the latest studies and simulations show that, in fact, hycean worlds are probably much drier and thus the ocean worlds we were envisioning shouldn't exist.Watch the video here (with no ads) or at YouTube: https://youtu.be/lDAIAXQkNrg

Astrophysicists may have spotted evidence for “dark stars,” an unusual type of star that could possibly have existed in the earliest days of the universe, in data from the James Webb Space Telescope. Instead of being powered by nuclear fusion as current stars are, the controversial theory says that these ancient dark stars would have formed by mixing a huge cloud of hydrogen and helium with a type of self-annihilating dark matter. Dark stars would not have been dark—researchers believe that if they existed, they would actually have been bigger and brighter than current stars.Astrophysicists Katherine Freese, who first proposed the idea of dark stars in 2007, and Cosmin Ilie, who detected the possible signs of the dark stars, join Host Ira Flatow to discuss the theory.  Guests:Dr. Katherine Freese is a theoretical astrophysicist and a professor of physics at the University of Texas at Austin.Dr. Cosmin Ilie is an assistant professor of physics and astronomy at Colgate University.Transcripts for each episode are available within 1-3 days at sciencefriday.com.

Harvard astrophysicist Avi Loeb joins Brian Keating to discuss a groundbreaking observation: the HiRISE camera on NASA's Mars Reconnaissance Orbiter has imaged 3I/ATLAS, a rare interstellar visitor, from the vantage point of Mars. In this episode, we explore: • What HiRISE detected and why it matters for planetary science. • How interstellar objects like ʻOumuamua and 3I/ATLAS challenge our theories. • Why Mars may become an ideal outpost for detecting future interstellar visitors. • The implications for astrobiology, planetary defense, and our search for extraterrestrial technology. ✨ Just as the 1977 “Wow! Signal” jolted radio astronomers with a one-time unexplained burst, 3I/ATLAS may be its optical cousin—an anomalous, fleeting, but potentially transformative messenger. Loeb even calculated that 3I/ATLAS's trajectory passed within about one degree of the Wow! Signal's sky position, making the connection more than metaphorical. Ignoring such rare alignments risks repeating history: anomalies slip through our fingers while orthodoxy insists nothing unusual happened. The Wow! Signal warned us of the danger of complacency; 3I/ATLAS reminds us that cosmic surprises often lurk at the margins of expectation, carrying lessons we may miss if we force every mystery into old categories. -

HEADLINE: Solving the Mystery of Bright Red Dots in the Early Universe GUEST NAME: Dr. Joel LejaSUMMARY: John Batchelor interviews Dr. Joel Leja about "little red dots"—extremely bright, mysteriously common objects discovered in the early universe by the James Webb Space Telescope. These enigmatic red dots appear to be early supermassive black holes, possibly tens of millions of solar masses, revealed by intensely hot gas swirling at tremendous velocities around them. Their unexpected abundance and size so close to the universe's beginning poses a fundamental challenge to current theories of cosmic evolution and black hole formation. The discovery suggests that supermassive black holes formed much earlier and more rapidly than previously thought possible, requiring astronomers to reconsider models of how the first galaxies and their central black holes emerged from the primordial darkness. Dr. Leja explains that while the JWST data strongly indicates these are black holes based on spectroscopic signatures, the mechanism that allowed such massive objects to form so quickly after the Big Bang remains one of astronomy's most perplexing new mysteries. The research highlights how advanced telescopes continue to overturn established assumptions about the early universe's structure and evolution.

James Webb can't resolve Earth-size planets around Sun-like stars. Not just because of the contrast but also because of the diffraction limit. To do that you need a mirror of 20+ meters. But what if you increase the size in just one direction? You get the required resolution but keep the mirror relatively small and easy to transport. This is the idea behind the Rectangular Mirror Telescope.Watch the video here (with no ads) or on YouTube: https://youtu.be/w3QXTW6DaIg

Can neutron stars create an equivalent of Type 1a supernovae? Can you land on Venus without a parachute? How do we know the shape of the Oort cloud? And in Q&A+, what's going on with 3I/ATLAS' weird tail situation?

Could we turn Earth into Jupiter by just adding more atmosphere? Can we train to communicate with aliens by talking to animals? How's YouTube destroying itself and it's getting really dangerous? And in Q&A+ will Vera Rubin find an asteroid on a collision course with Earth?

Dust is a big problem for Moon and Mars. It sticks to everything, breaks things, covers solar panels. So, how do you solve this problem? One possible solution is an electric shield that uses charged surfaces to repel the dust.
