L'astéroïde dévié par la Nasa a changé d'orbite autour du Soleil Il y a quatre ans, la Nasa faisait s'écraser un vaisseau sur un petit astéroïde pour tenter de dévier sa trajectoire, une manoeuvre digne d'un roman de science-fiction qui visait à apprendre comment p...

Planetary Defense: We deflect asteroids, but we can't find them. 15.000 asteroidi possono distruggere una città e non sappiamo dove sono. La difesa planetaria esiste sulla carta: nella realtà, meno.

NASA proved it can deflect an asteroid. Then it scrapped the only spacecraft that could do it. Now it admits 15,000 city-killer rocks are out there, untracked. The telescope to find them costs less than an aircraft carrier.

Hunting for the Lunar Debris Hiding Near Earth The Moon has a long history of being smacked by large rocks. Its pock-marked, cratered surface is evidence of that. Scientists expect that, as part of those impacts, some debris would be scattered into space - and that we should be able to track it down. But so far, there have been startlingly few discoveries of these Lunar-origin Asteroids (LOAs) despite their theoretical abundance. A new paper from Yixuan Wu and their colleagues at Tsinghua University explains why - and how the Vera Rubin Observatory might help with finding them.

Asteroid impact simulation reveals the hidden strength of space rocks Physicists at the University of Oxford have contributed to a new study which has found that iron-rich asteroids can tolerate far more energy than previously thought without breaking apart—a breakthrough with direct implications for planetary defense strategies. The findings have been published in Nature Communications.

Iron asteroids are tougher than we thought! 💪 Oxford study reveals they can withstand immense energy—a game-changer for defending Earth. ☄️ #PlanetaryDefense

Un astéroïde de la taille d’un bus est passé près de la Terre le 22 décembre, confirme la NASA Un astéroïde de petite taille a survolé l’orbite terrestre le 22 décembre 2025. Un passage suivi de près par la NASA, sans aucun danger pour la planète.

Un astéroïde gros comme un bus a frôlé la Terre le 22 décembre. Pas de panique, mais le rappel est clair. NASA veille.

Life From Space? ☄️ Apophis, "Alien" Water & The Terrifying Truth About Asteroids Is the thing that created us also waiting to destroy us? ☄️🧬 For years, we looked at asteroids as just dead, floating rocks. But recent samples returned from missions like OSIRIS-REx and Hayabusa2 have blown that assumption out of the airlock. In this episode, we dive deep into the terrifying and beautiful truth hidden inside space debris. We explore how these ancient rocks aren't just threats—they are likely the architects of life itself, carrying the liquid water, amino acids, and pre-solar grains that jumpstarted existence on Earth. But here is the catch: The same physics that delivered life is also a ticking time bomb. We breakdown the latest data on Potentially Hazardous Objects like Bennu and the infamous Apophis. We discuss why Hollywood gets it wrong—you can't just "nuke" these asteroids because they are actually "rubble piles" that absorb shockwaves like a sponge. In this cosmic deep dive, we uncover: - The Blueprint of Life: How samples predating our Sun prove that the ingredients for our oceans came from the stars. - The "Rubble Pile" Problem: Why planetary defense is harder than we thought and why these rocks are so hard to deflect. - The Threat List: A look at the trajectories of Apophis and Bennu and the catastrophic energy they hold. - Physics Defying Anomalies: The unusual magnetic signatures and radioactive isotopes that are rewriting solar system history. Join us as we walk the fine line between scientific wonder and existential dread. Are we looking at our ancestors, or the bullet with our name on it? Topics: Space Science, Planetary Defense, Astrobiology, NASA Missions, Apophis, and the Future of Earth. 🎧 Strap in and press play—let’s find out what’s incoming.

La mission conjointe de l'ESA et de l'Agence japonaise d'exploration aérospatiale JAXA doit étudier le survol de la Terre par l’astéroïde « Apophis » en Avril 2029. L'Université de Berne participe à la mission en fournissant la caméra CHANCES. Cette caméra prendra des images à haute résolution pour étudier de possibles changements de la nature et des propriétés de la surface d'Apophis sous l'influence des forces de marée terrestres.

XRISM Records First X‑Ray Signal from Interstellar Object 3I/ATLAS as Agencies Stage Coordinated Defense Drills Cristina Gomez outlines new scientific findings on interstellar object 3I/ATLAS, including the first-ever X-ray detection reported by Japan’s XRISM satellite and anomalous sunward jet activity captured by ground and space telescopes. The update also covers coordinated planetary-defense exercises by ESA, JAXA, the U.S. Space Force, and partners, alongside Avi Loeb’s call for open inquiry and his “swarm” hypothesis ahead of the object’s December 19, 2025, closest approach to Earth.

XRISM records first X-ray detection of interstellar object 3I/ATLAS as telescopes spot anomalous sunward jets. ESA, JAXA, USSF run joint planetary defense drills while Avi Loeb urges open inquiry before Dec 19, 2025 approach. #XRISM #3IATLAS #PlanetaryDefense

3I/Atlas "Wakeup Call": Why 27 Nations Are Drilling for Doomsday (Planetary Defense or Panic?) Is this the end of the world, or just a really expensive fire drill? ☄️ Imagine waking up to news that an interstellar object is hurtling toward Earth with the mass and speed to wipe out a continent. Sounds like a sci-fi movie, right? Well, for 27 nations across Europe, this nightmare scenario just became their Monday morning to-do list. In this episode, we dive deep into the viral WION report covering Europe’s unprecedented planetary defense drill. Triggered by the arrival of the mysterious interstellar comet 3I/Atlas, scientists and governments are no longer asking "if" but "when." We are breaking down exactly what this continental wakeup call means for you. We aren't just talking science; we’re reacting to the thrill, the panic, and the sheer scale of this simulation. While experts swear 3I/Atlas is passing harmlessly (so they say...), this massive coordination of 27 nations suggests that humanity is finally taking cosmic threats seriously. In this episode, we cover: - The Reality Check: Why the European planetary defense drill is happening now. - The Threat: What happens if an object like 3I/Atlas actually hits? - The WION Reaction: Breaking down the global response to this space threat. - Dinosaurs vs. Us: Why preparedness is the only thing separating us from history’s fossils. Are they preparing for something they aren't telling us, or is this just good insurance? Grab your tinfoil hats and your survival kits—we’re figuring out if Earth is actually ready for the unthinkable. Don't wait for the impact! 🎧 Hit that PLAY button, SUBSCRIBE so you don't miss the apocalypse, and SHARE this episode with a friend who needs a wakeup call!
