The nature of space, time and the evolution of life on Earth mean it’s unlikely extraterrestrial life has visited our home planet.

UCLA-led astronomers have discovered the first known "disappearing planet" about 1,000 light-years away. The planet, TOI-2535 b, is a "hot Jupiter," a gas giant that orbits extremely close to its host star. TOI-2535 b whips around its star in only 8.25 days—10 times faster than the 88 days that Mercury takes to go around our sun once.

Cracks along a giant Martian volcano, possibly above a magma chamber, might be spewing magmatic gases into the atmosphere, according to a new study. The fissures might host environments akin to Earth's hydrothermal vents, where life on our planet may have emerged

🛸 Did humanity just intercept its first official broadcast from an alien civilization? In this thrilling episode, we break down and react to the viral report from WION regarding the mysterious signal NBS260108. Chinese researchers using the world's largest radio telescope—the FAST Telescope—have picked up an extraordinary radio emission coming directly from the K2155 star system, located 238 light-years away from Earth. What makes signal NBS260108 so disturbing yet exciting? Unlike natural cosmic noise, this signal features a narrow frequency band and a gradual frequency shift—the exact theoretical hallmarks of an artificial technosignature created by an advanced extraterrestrial intelligence! Here is what we uncover in this episode: - 📡 The Origin: Why star system K2155 with its three super-Earth planets in the habitable zone is the ultimate target for astrobiologists. - 🔬 The Evidence: Could this frequency shift prove movement from an alien transmitter or spacecraft? - 🌌 The Skepticism vs. Truth: What mainstream scientists are saying vs. what this means for humanity's future. Are we finally on the verge of proving we are not alone in the cosmos, or is this another interstellar false alarm? Hit play to dive into the evidence with us! 🔔 Loved this episode?

It's a dizzyingly busy time for scientists searching for life on distant planets. To date, astronomers have cataloged more than 6,000 planets beyond our solar system and are searching the atmospheres of the most promising worlds for chemicals that might be byproducts of life. Astrobiologists are particularly interested in atmospheres like Earth's that trap enough heat to support liquid water on the planet's surface, which scientists consider the key factor in determining whether a planet can support life as we know it.

Scientists have created a computer model of Earth on which life never existed. It could help astronomers determine whether chemical compounds in the atmospheres of distant exoplanets indicate the presence of living organisms or can be explained entirely by natural geological processes. The model recreates 5 billion years of chemical interactions between the planet’s core, […] Post Scientists Create a Digital Earth Without Living Organisms to Search for Alien Life at Root-Nation.com.

There are cunning creatures in the cosmos, their universe is more vicious, more violent than the many monsters I might imagine ...

Ever feel like you’re being watched? 🛸 What if the silence of the cosmos isn't an accident, but a quarantine? Welcome to the ultimate deep dive into the Fermi Paradox. We are tackling the unsettling question: Why haven't we made contact with alien life? In this episode, we break down the Zoo Hypothesis and the Jungle Hypothesis—the theories suggesting humanity is being observed like animals in a preserve or ignored like an insignificant anthill. What we cover: - The Lagrange Points Theory: Why aliens might be parked right in our backyard using hidden, gravity-stable orbits. - The Maturity Filter: Are we simply not ready for the galactic conversation? - Cosmic Silence: Why the 'Great Filter' might be closer than you think. Whether you're a science enthusiast or a high-stakes theorist, this episode challenges everything you think you know about our place in the universe. We’re moving beyond the math and into the existential mystery of our existence. 🌌 👉 Listen until the end to hear our take on why the most advanced civilizations are ignoring us.

Some scientists think there are more habitable worlds than Earth out there. What are they like? And how might we find them?

A scorching lava planet 280 light-years away has surprised astronomers by apparently maintaining a thick atmosphere despite conditions that should have stripped it away billions of years ago. James Webb Space Telescope observations suggest that TOI-561 b reflects about 75% of incoming starlight, possibly because of mineral clouds that act like a giant sunscreen. The planet may also be continually replenishing its atmosphere through gases released from a global ocean of molten rock.

Finding alien life isn't about spotting little green men. It's way more complex than that.

Get ready for the age of private space telescopes. The Lazuli Space Telescope will launch in a few years and part of its mission is to observe exoplanets. New research presents a list of 27 exoplanet targets, some of which are very well-known and will certainly benefit from deeper observations.

A new Lake Untersee expedition will study Antarctic microbes and sediments, testing how scientists recognise and date possible signs of life on other worlds.

Investigative reporter Linda Moulton Howe presents a detailed framework in which an advanced extraterrestrial civilization known as the Ebens allegedly engineered humanity, cloned multiple alien species, and managed Earth as a long-running genetic and social experiment. Drawing on leaked manuals, crash-retrieval testimony, abduction accounts, and an alleged presidential briefing for Ronald Reagan, she outlines a system of friendly, neutral, and hostile nonhuman groups, their claimed star systems, and their competing agendas around human genetics and ‘body containers’ for alien souls.

**[Max Planck Institute for Extraterrestrial Physics]** Liquid water is considered essential for life. Surprisingly, however, stable conditions that are conducive to life could exist far from any sun. A research team from the Excellence Cluster ORIGINS at LMU and the Max Planck Institute for Extraterrestrial Physics (MPE) has shown that moons around free-floating planets can keep their water oceans liquid for up to 4.3 billion years by virtue of dense hydrogen atmospheres and tidal heating – that is to say, for almost as long as the Earth has existed and sufficient time for complex life to develop. Planetary systems often form under unstable conditions. If young planets come too close, they can fling each other out of their orbits. This creates free-floating planets (FFPs), which wander through the galaxy without a parent star. An earlier study by LMU physicist Dr. Giulia Roccetti had shown that gas giants ejected in this way do not necessarily lose all of their moons in the process. **Tidal heating keeps oceans liquid** The ejection does, however, alter the orbits of the moons. They become highly elliptical, such that their distance from the planet constantly changes. The resulting tidal forces rhythmically deform the lunar body, compress its interior, and generate heat through friction. This tidal heating can be sufficient to maintain oceans of liquid water on the surface – even without the energy of a star, and in the cold of interstellar space. **Hydrogen as stable heat trap** The atmosphere determines whether this heat is retained at the surface. On Earth, carbon dioxide functions as an effective greenhouse gas. Earlier studies had demonstrated that carbon dioxide could stabilize life-friendly conditions on exomoons for periods of up to 1.6 billion years. Under the extremely low temperatures of free-floating systems, however, carbon dioxide would condense, causing the atmosphere to lose its protective effect and allowing heat to escape. And so the research team from the fields of astrophysics, biophysics, and astrochemistry investigated hydrogen-rich atmospheres as alternative heat traps. Although molecular hydrogen is largely transparent to infrared radiation, a crucial physical effect arises under high pressures: collision-induced absorption. In this process, colliding hydrogen molecules form transient complexes that can absorb thermal radiation and retain it in the atmosphere. At the same time, hydrogen remains stable even at very low temperatures. **Parallels to early Earth** The findings also furnish new clues to the origin of life. “Our collaboration with the team of Professor Dieter Braun helped us recognize that the cradle of life does not necessarily require a sun,” says David Dahlbüdding, doctoral researcher at LMU and lead author of the study. “We discovered a clear connection between these distant moons and the early Earth, where high concentrations of hydrogen through asteroid impacts could have created the conditions for life.” Tidal forces could not only supply heat, but also drive processes of chemical development. Periodic deformation gives rise to local wet-dry cycles, in which water evaporates and then condenses again. Such cycles are considered an important mechanism for the formation of complex molecules and could facilitate crucial steps on the path to the emergence of life. **Moons hospitable to life in interstellar space** Free-floating planets are thought to be common. According to estimates, there could be as many of these ‘nomadic’ planets in the Milky Way as there are stars. Their moons could provide stable habitats for long periods of time. The new findings could thus significantly broaden the spectrum of possible environments that could harbor life – and show that life could arise and endure even in the darkest regions of the galaxy. **_David Dahlbüdding, Tommaso Grassi, Karan Molaverdikhani, Giulia Roccetti, Barbara Ercolano, Dieter Braun, Paola Caselli.Habitability of Tidally Heated H2-Dominated Exomoons around Free-Floating Planets.
