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.

Are the most important breakthroughs in physics deliberately hidden? In this deep, unfiltered conversation, Prof. Simon returns to explore how advanced physics may have been locked away since WWII — from zero-point energy and plasma stealth to the classified “black world” of defense research. We revisit legendary test pilot Dan Isbell's extraordinary UAP encounters and the physics they suggest, and we ask: Has mainstream science been steered off course for decades? Topics we explore: – Why WWII and the Manhattan Project may have shifted physics into secrecy – Test pilot insights on exotic craft, plasma sheathing, and zero-point energy – The quantum vacuum vs. the old “ether” — and why the words changed – Suppressed experiments from Faraday to Tesla to Chris Chiba today – Passive radar, Gorgon Stare, and citizen-built detection networks – The real split between mundane UAPs and the 5% that defy known physics – Consciousness, remote viewing, and the idea of a connected universe This is a rigorous but open-minded discussion for anyone serious about UAPs, advanced propulsion, and the future of physics.

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

Ep. 135 – Mystery Drones & Interstellar Warnings: 3I/Atlas, NATO, and War DrumsThis week Adam and Topher unpack a whirlwind of developments at the crossroads of geopolitics, UAP disclosure, and cosmic anomalies.

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?

https://www.youtube.com/watch?v=yH4uczqmhQ0 From Jan 20, 2023. The James Webb Space Telescope took time away from finding the earliest galaxies or imaging incredible nebulae to test out its planet hunting capabilities. To say it was immediately successful would be an understatement. JWST is showing us that it can do almost anything in astronomy and cosmology.   Its latest trick is picking out an exoplanet candidate, confirming it exists and telling us about this alien world. LHS 475 is a red dwarf star 41 light-years away from our Solar System in the southern hemisphere constellation of Octans. And now we know a lot more about its planet, LHS 475 b.   We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.  Just visit: https://www.patreon.com/365DaysOfAstronomy and donate as much as you can!

Il y a dix milliards d'années, l'univers n'en était encore qu'à ses débuts. Le Big Bang avait eu lieu depuis à peine 3 ou 4 milliards d'années, et pourtant, une incroyable effervescence était en cours. Des étoiles naissaient par millions, les galaxies fusionnaient, les structures à grande échelle prenaient forme. Cette époque, souvent décrite comme l'adolescence du cosmos, est une phase de transition cruciale pour comprendre ce que l'univers est devenu aujourd'hui. Mais malgré tous nos outils, cette période reste encore floue, et pleine de surprises.Grâce au télescope spatial James Webb, les scientifiques commencent à voir cette époque lointaine avec un niveau de détail inédit. Et ce qu'ils découvrent pose de nouvelles questions. Certaines galaxies observées paraissent bien trop massives, trop lumineuses ou trop nombreuses pour correspondre à ce que nos modèles prédisaient. L'univers primitif semble s'être structuré plus vite qu'on ne le pensait. Est-ce que nos théories actuelles sont incomplètes ? Ou est-ce qu'on interprète mal les signaux que nous envoie le passé ?Dans cette vidéo, on remonte le fil du temps pour explorer cette zone-clé de l'histoire cosmique. On revient sur les grandes étapes qui ont conduit à la formation des premières galaxies, on décrypte les dernières observations du JWST, et on examine les hypothèses proposées pour expliquer les anomalies récentes. Car comprendre l'univers d'il y a 10 milliards d'années, c'est aussi interroger nos certitudes et accepter que le cosmos ne se laisse jamais enfermer dans des modèles trop simples.

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.

Building infrastructure on the Moon, Earth gets a new quasi-satellite, a black hole has wandered away from the center of its galaxy, and a tour through star forming nebulae thanks to Gaia. And on Space Bites+, China's new neutrino detector comes online.

Join astronomers Franck Marchis (SETI Institute) and Julien Girard (Space Telescope Science Institute) for a 30-minute live discussion unpacking NASA's exciting new findings from JWST. Just announced, JWST has revealed strong evidence of a Saturn-mass gas giant orbiting Alpha Centauri A—the Sun's nearest solar twin—located just 4 light-years away. The planet appears to orbit at about 1 to 2 AU, placing it within the star's habitable zone, though as a gas giant, it's not likely habitable itself. (Recorded live 8 August 2025.)

How can we realistically tell if 3I/ATLAS is an alien spaceship or not? Can we turn an interstellar comet into a transmitter? Would the government suppress information about a dangerous asteroid? And in Q&A+, why aren't there more asteroids outside the solar system?

Who will name Planet X if/when it is discovered? How will cats deal with the toilet situation if they go to space? Can a star block an entire galaxy? And in Q&A+ what happens if we find proof that there's no life elsewhere?

In 2022 legde de Webb ruimtetelescoop merkwaardige rode stippen vast. Er is veel gespeculeerd over de ware aard van deze stippen, die trouwens minstens 12 miljard jaar oud moeten zijn. Onlangs publiceerden astronoom Anna de Graaff en collega's een opmerkelijke nieuwe theorie.“Black Hole Stars” could solve JWST riddle of overly massive early galaxies:https://www.mpia.de/news/science/2025-06-black-hole-starsA remarkable Ruby: Absorption in dense gas, rather than evolvedstars, drives the extreme Balmer break of a Little Red Dot at z = 3.5:https://arxiv.org/pdf/2503.16600De Zimmerman en Space podcast is gelicenseerd onder een Creative Commons CC0 1.0 licentie.http://creativecommons.org/publicdomain/zero/1.0

Matt Woods – Perth Observatory with Bruce Welsh Mars’ Interior Structure and Implications Perseverance Rover: Potential Biosignatures Found on Mars TRAPPIST-1 e in the JWST’s Spotlight See omnystudio.com/listener for privacy information.

Join communications specialist Beth Johnson for a live interview with astrophysicist Marc Hon (MIT), lead author of a new study revealing one of the most extreme exoplanets ever discovered — a small, rocky world that's literally disintegrating as it orbits its star. BD+05 4868 b is a Mercury-sized planet just 140 light-years away that's orbiting so close to its star, it's roasting at around 1650°C. The heat is intense enough to vaporize the planet's rocky surface, creating a massive comet-like tail of mineral dust stretching millions of kilometers across space. This rare discovery — only the fourth known disintegrating planet — offers scientists an unprecedented opportunity to study the geology of an alien world, and upcoming JWST observations could even reveal the chemical makeup of its interior. (Recorded live 17 July 2025.)

Has Perseverance found signs of life on Mars? Webb scans TRAPPIST-1e for signs of an atmosphere. 3I/ATLAS grows a tail, and could get a mission. And on Space Bites+, Webb sees a cloud of methane around the dwarf planet Makemake.

Can we make Earth invisible for possible alien invaders? What's the deal with the pyramids and their alignment to stars? Can an interstellar ship casually crash into a black hole? And what's the difference between cosmology and astronomy after all?

An interstellar interloper may have been a chip off the old block, where the old block was a Pluto-like planet around another star, and the chip is solid air (nitrogen that is)! And we revisit the potential role of axions in the great dark matter chase and a new way that JWST may help us answer it. Join us for all that, exoplanets, science fiction trivia and more.

What's the highest energy a photon can have? Is Titan just a huge fire hazard floating in space? How do they measure the masses of planets with just satellites? And in Q&A plus, what realistic scifi is worth watching?

In this episode of The Space Between, we dive headfirst into one of the hottest debates in modern cosmology: the true age of the universe and what new data from the James Webb Space Telescope (JWST) means for our understanding of cosmic expansion. Headlines are screaming “crisis” and claiming the universe is expanding at two different speeds—so what's fact, what's speculation, and what's just sensational storytelling?We explore the “Hubble Tension,” the discrepancy between early-universe and late-universe measurements of cosmic expansion, and why JWST's confirmation of Hubble's data is such a big deal. At the same time, we break down how the science gets spun in the media—why articles about “two universes” or “multiple speeds” of expansion may capture clicks, but miss the nuance of what astronomers are actually saying.Expect a blend of astrophysics, philosophy, and some critical media literacy as we ask: how should we talk about cosmic uncertainty without losing public trust in science?---Articles:The unthinkable confirmed - James Webb and Hubble prove that the universe is expanding at two different speeds, throwing cosmology into crisisNew measure of the universe's expansion suggests resolution of a conflictNASA's Webb, Hubble Telescopes Affirm Universe's Expansion Rate, Puzzle PersistsWebb telescope confirms the universe is expanding at an unexpected rate---JOIN OUR LIVE SHOW ON EVERY FIRST SUNDAY OF THE MONTH AT 9p CENTRAL TIME (GMT-5) AT THIS LINK!⁠https://riverside.fm/studio/kolby-van-camps-studio-eMegK⁠Follow us on Instagram! ⁠⁠⁠⁠⁠https://instagram.com/spacebetweenpod⁠⁠⁠⁠⁠Order Kolby's new album! ⁠⁠⁠⁠⁠https://kolbyvancamp.hearnow.com/portraits-volume-ii⁠

3I/ATLAS is very different from any comet we've ever seen before, Mars is filled with fragments from ancient impacts, ESA loses contact with JUICE right before an important flyby, and the highest resolution image of a solar flare ever seen. And on Space Bites+, why asteroid made of the same material can have different colors.

Newly released but heavily redacted NASA documents involving the James Webb Space Telescope are creating dramatic controversy, and in this episode of Mysteries with a History we will dig into what hints can be gleaned from the documents, and also the latest Exoplanet findings.To see the VIDEO of this episode, click or copy link - https://youtube.com/live/uKHm9aDA0hsVisit my website with International UFO News, Articles, Videos, and Podcast direct links -www.ufonews.coBecome a supporter of this podcast: https://www.spreaker.com/podcast/strange-and-unexplained--5235662/support.

Astronomers are using the Webb Telescope to shine a little light on the bizarre magnetic field surrounding Neptune.

Which is a bigger showstopper for a human Mars mission: food or radiation exposure? Does Vera Rubin leave any chance for aliens to still sneak upon us? Can something like space whales actually exist? And in Q&A+, when can we find out what dark matter and dark energy actually are?

Astronomers are using the JWST to determine if the morning star us even a star. Blue Origin is set to launch their 2nd New Glenn rocket as soon as the end of the month. New research from JWST says that the oldest known black hole is more than 13.3 billion years old. Plus the most massive black hole ever found is 36 billion times the mass of our sun. Become a supporter of this podcast: https://www.spreaker.com/podcast/made-of-stars--4746260/support.

The Wow signal was even more Wow. Starship Flight 10 makes it space and returns to Earth, more red dwarf planets get crossed off the list as lacking an atmosphere, a supernova spilled its guts into space. And on Space Bites+, finding supernovae as quickly as possible.

The boys are back! Discussing all the things that happened during Starship IFT-10. Why didn't they catch the Super Heavy booster? What did explode near the engines? Why was Starship orange? What's next for SpaceX? Looking for all the answers with Scott Manley and Marcus House.

We definitely won't see a space elevator built in any foreseeable future. But there is a similar but much more practical approach – a skyhook. How close are we to creating one? Why is it useful? What challenges does it bring and when can we expect first practical demonstrations? Finding out in this interview.

Can the difficulty of interstellar travel the answer to the Fermi paradox? Or maybe it's the fact that we can only apply it to our galaxy and not further? Or maybe we can even find life in our solar system?

When is a supernova too close for comfort? Will USA's Moon race against China accelerate a race towards a Mars base? How can we see the Oort cloud? And in Q&A+, what do I tell to space deniers?

Ryugu and Bennu are related, a star tried to eat a black hole and it didn't go well, using moons to save fuel, and China tests its new human lunar lander. In Space Bites+, how climate change will impact satellite orbits.

Why do people believe Starships will go to Mars? Can we use molten salt batteries on the Moon? What's the difference between the Universe and the Observable Universe? And in Q&A+, what's the chance of hitting an stone during an interstellar voyage?

In 2020, the YSES-1 system became the first directly imaged multiplanetary system around a Sun-like star. It features two giant exoplanets orbiting a star just 16 million years old. Now, the James Webb Space Telescope is revealing new insights into these distant worlds. Host Sarah Al-Ahmed speaks with Kielan Hoch, Giacconi Fellow at the Space Telescope Science Institute and principal investigator of the JWST program that captured these observations, and Emily Rickman, ESA science operations scientist at STScI and member of the JWST Telescope Scientist Team for coronagraphy. They explore what makes this system so unusual, including a dusty circumplanetary disk around YSES-1b and high-altitude silicate clouds in the atmosphere of YSES-1c. Later in the show, Bruce Betts joins for What’s Up to talk about how future telescopes like the Habitable Worlds Observatory could help us image smaller, colder, and older planets.

Satellites are causing light pollution. Every year there a more of them. So, why don't they just paint them all vantablack, the ultra-black coating that doesn't reflect almost any light? Finding out in this interview.

Is living in the clouds of Venus better than living in sub-surface habitats on Mars? Can we really lock ourselves from orbit with space junk? Should we build another version of Biosphere before going to Mars? And in Q&A+, is abiogenesis really unlikely?

Finally, Webb's analysis of TRAPPIST-1d, new Hubble images comet 3I/ATLAS, the most massive black hole ever discovered, why Mars sand is so dangerous. And in Space Bites+, staring right down the jet of an actively feeding supermassive black hole.

What would happen if we moved a jovian moon to Mars? What are black holes spitting out as those jets? What's the best case scenario for Europa Clipper's search for life? And in Q&A+, how are we searching for Sun-like stars?

How did supermassive black holes get so big so early? There are two main models for that, and JWST just got a huge boost for the one that suggests they can form via a direct collapse of gas clouds. How did the researchers pull the first observations of a potential birth of a SMBH? Finding out in this interview.

Is there an upper size limit for black holes? Why don't we build multiple identical missions to increase the chance of success? Is the Universe considered finite or infinite? And in Q&A+, is the Universe expanding or is everything else just shrinking?

A Planet Found at Alpha Centauri. Webb Revisits the Hubble Ultra Deep Field. Little Red Dots don't break the laws of physics. In Space Bites Plus, showing that the Earth's magnetosphere was here for a long time.

Could we aim asteroid YR4 at the Moon on purpose? What would happen to babies born and raised on Mars? Should we use water as an insulation layer for our spacecraft? And in Q&A+, could we mine an asteroid that's stuck in a Lagrange point?
