SETI Study Reveals Space Weather Could Be Hiding Alien Signals From Earth In the early 2000, my computer screen — like those of countless space enthusiasts — was often filled with bands of rainbow-coloured spectral signals. As my machine processed thousands of radio data points gathered by the SETI@Home project, I hoped I might be contributing, even in a small way, to one of humanity's most ambitious scientific pursuits: the search for extraterrestrial life. However, a new study published in The Astrophysical Journal by Vishal Gajjar and Grayce Brown of the SETI Institute suggests that the specific signals SETI@Home was designed to detect may not actually exist. This does not mean that alien civilizations are not transmitting signals into space; rather, the influence of space weather from their host star could alter those signals so dramatically that they become unrecognizable by the time they reach Earth. Why SETI Scientists Expected Narrow Alien Radio Signals Signals present a...

Revolutionary Lunar Origin Theory Challenges Decades-Old Planetary Science Models Long-Standing Mystery: How the Moon Really Formed One of the longest-standing mysteries in planetary science is how the Moon came into being. More than a century ago, George Darwin suggested that powerful tidal and centrifugal forces acting on a rapidly spinning proto-Earth caused the Moon to break away and settle into orbit around the planet. However, the idea later conflicted with the laws of conservation. A proto-Earth rotating with a day lasting just two to three hours would have possessed roughly four times the angular momentum of the present Earth-Moon system, raising the question of where that excess momentum went. Theia Impact: The Dominant Modern Hypothesis The leading explanation that emerged instead proposes that a Mars-sized object, dubbed Theia, collided with the proto-Earth. The impact ejected material from both bodies into orbit, where it eventually clumped together to form the Moon. When ...

Rare Optical Flare AT2022zod May Be an Unusual Tidal Disruption Event, Astronomers Say International Team Investigates a Powerful and Mysterious Flare Study Posted on arXiv Reveals New Clues to a Rare Phenomenon An international team of astronomers has examined a brief but intense optical flare known as AT2022zod, uncovering evidence that it may represent an unusual tidal disruption event. Their results, posted on 1 December on the arXiv pre-print server, shed new light on this rare phenomenon. A tidal disruption event (TDE) occurs when a star wanders too close to a supermassive black hole and is torn apart by immense tidal forces. The shredded stellar material then spirals inward, producing radiation from the innermost regions of the accreting debris — a telltale hallmark of a TDE. A Mysterious Flare Observed in 2022 Optical Outburst Lasted Just Over a Month AT2022zod was observed as an optical flare lasting just over a month, from 13 October to 18 November 2022, with a rise of rough...

New Study Reveals Fresh Insights Into Milky Way's Chemical Evolution Research Published in MNRAS Sheds Light on Chemical Bimodality Fresh insights into how galaxies such as our Milky Way form, evolve and develop unexpected chemical signatures have emerged from a new study. Published in Monthly Notices of the Royal Astronomical Society , the research investigates the origins of a long-standing mystery in our galaxy: the existence of two chemically distinct populations of stars, a phenomenon known as "chemical bimodality." Astronomers Identify Two Distinct Stellar Populations When astronomers examine stars in the Sun's neighbourhood, they consistently uncover two major groups distinguished by the relative amounts of iron (Fe) and magnesium (Mg) they contain. These groups trace separate sequences on chemical plots, even though they overlap in overall metallicity — an enduring puzzle that has intrigued researchers for decades. Simulations Reveal How Milky Way-Type Galaxi...

Chang'e-6 Lunar Dust Uncovers Ancient Meteorite Fragments That Could Rewrite the Story of Life's Origins (FSNews365 Science | Space Research | October 2025) A Groundbreaking Discovery from the Moon's Hidden Face Lunar Dust retrieved by China's Chang'e-6 mission has unveiled rare meteorite remnants that could transform our understanding of how water and life's essential elements formed in the solar system . In June 2024 , the Chang'e-6 spacecraft successfully brought back the first-ever samples from the Moon's far side   —  the hemisphere forever hidden from Earth. According to a new study published in the  Proceeding of the National Academy of Sciences (PNAS) study, these materials suggest that water-rich asteroids — once thought to be rare may have supplied far more substance to the early Earth and Moon than previously believed.

Black Hole Breakthrough: Curtin University Astronomers Track Rare Tidal Disruption Event AT2019azh Edited by Fasi Uddin A Cosmic Catastrophe Caught in Action Astronomers at Curtin University , working alongside international collaborators, have uncovered new insights into a rare and violent astronomical phenomenon: a tidal disruption event (TDE) . Their findings released on 22 September via arXiv , detail years of radio monitoring of the event known as AT2019azh , offering a deeper understanding of how black holes tear stars apart and how the aftermath evolves over time. For readers who follow cutting-edge discoveries in space science and physics, more breaking reports are available at FSNews365 . What Exactly Is a Tidal Disruption Event? When a star strays too close to a supermassive black hole , it is pulled apart by overwhelming tidal forces. Roughly half of the stellar material is flung into space, while the rest forms a spectacular flare as it spirals into the black hole. This pr...

NASA and Chilean Scientists Study 3I/ATLAS, A Comet That Breaks the Rules Interstellar visitors are rare guests in our Solar System , but when they appear they often rewrite the rules of astronomy. Such is the case with 3I/ATLAS , a fast-moving object that has left scientists puzzled with its bizarre behaviour. Recent findings from NASA and Chilean researchers reveal that this comet-like body is expelling an unusual plume of nickel — without the iron that typically accompanies it. The discovery challenges conventional wisdom about how comets form and evolve, sparking both excitement and controversy across the scientific community. A Cosmic Outsider: What Is 3I/ATLAS? The object 3I/ATLAS —the third known interstellar traveler after "Oumuamua (2017) and 2I/Borisov (2019) —was first detected in July 2025 by the ATLAS telescope network , which scans he skies for potentially hazardous objects. Earlier images from Chile's Vera C. Rubin Observatory had unknowingly captured it, but ...
