Earth-Like Rocky Planets May Be Far More Common Across the Galaxy, Scientists Say Rocky planets similar to Earth could be far more widespread than astronomers once believed, opening new possibilities in the search for life beyond our solar system. New findings suggest a powerful cosmic process may have played a critical role in shaping dry, habitable worlds throughout the Milky Way. For more space and planetary science updates, visit FSNews365 Supernova Shockwaves May Have Shaped Earth-Like Worlds Rocky planets similar to Earth may be far more widespread than once believed, according to new research published in Science Advances . The study suggests that, during the formation of our solar system, a nearby supernova flooded the region with cosmic rays carrying radioactive elements capable of creating dry, rocky worlds. If correct, this process may be common throughout the galaxy. How Earth-Like Planet Formed in a Radioactive Environment Earth-like planets are thought to form from plane...

Auroras on a Rogue Planet: James Webb Spots Dazzling Weather Beyond Our Solar System edited by  Fasi Uddin, 27 September 2025 In an unprecedented discovery, astronomers at Trinity College Dublin have reported aurora-like activity on a rogue planet wandering through space. Using the cutting-edge NASA/ESA/CSA James Webb Space Telescope (JWST) , the team observed shimmering atmospheric phenomena on SIMP-0136 , a hot and restless world unbound to any star. This marks a milestone in exoplanet weather science , offering new insights into alien atmospheres and the extreme conditions shaping them. A Cosmic "Weather Report" Like No Other Unlike Earth's daily forecasts, the "weather" on SIMP-0136 is written in fire and storms, Astronomers tracked faint fluctuations in brightness as the planet rotated, revealing subtle atmospheric shifts. These signals allowed the team to map temperature, cloud distribution and chemical composition in remarkable detail. Dr. Evert Nasedki...

Does Planetary Evolution Support Human-Like Life? New Study Suggests We're Not Alone Introduction: Rethinking Human Uniqueness in Evolutionary Progression According to a fresh scientific model, humans may not be unique, but instead the expected outcome of evolutionary progression on Earth and likely other worlds. A New Model Shakes Up the 'Hard Steps' Theory of Evolution A new model overturns the decades-old 'Hard Steps' theory , which posited that intelligent life was an extremely unlikely event. According to Penn State researchers , this fresh interpretation suggests that the development of intelligence may have been a more natural and probable evolutionary process, thereby increasing the chances of its existence beyond Earth. This Represents a Fundamental Change in Our Understanding of Life's History "This represents a fundamental change in our understanding of life's history," said Jennifer Macalady , professor of geosciences at Penn State and ...

Scientists Confirm Exoplanet with Potential to Sustain Life Discovery of a Super-Earth in the Habitable Zone Researchers have confirmed the detection of a super-Earth within the habitable zone of a sun-like star close to our solar system, Initially observed two years ago by Dr. Michael Cretignier of Oxford University , this result — supported by more than 20 years of observations —marks a significant step in identifying exoplanets capable of sustaining life. Meet HD 20794 d  — A Super-Earth in the Habitable Zone The newly identified exoplanet, HD 20794 d , possesses a mass six times that of Earth and orbits a sun-like star located a mere 20 light-years away . Positioned within the system's habitable zone . its orbit suggests conditions suitable for sustaining liquid water —an essential prerequisite for life. These findings have been detailed in Astronomy & Astrophysics . Initial Detection and Data Analysis HARPS Observations Dr. Cretignier identified a candidate exoplanet in ...

Astronomers Challenge the Theory That Venus Once Had Liquid Water Introduction: Debunking Venus's Habitability Astronomers have concluded that Venus has never been habitable, debunking decades of speculation about its Earth-like  past. Researchers from the University of Cambridge analyzed Venus's atmos pheric chemistry and concluded that its interior is too arid to have su p ported oceans, suggesting the  planet has always been a hot and uninhabitable world. New Findings on Venus's Atmos phere and Evolution Study Published in Nature Astronomy Published in Nature Astronomy , these findings highlight Earth's distinctiveness and refine the search for extraterrestrial life, em phasizing the need to focus on Earth-like exo planets rather than Venus-like ones. Venus: Earth's Unforgiving Twin Viewed from a distance, Venus bears a striking resemblance to Earth, matching in size and rocky com position, but on closer examination, it presents as an unforgiving twin with sulfu...

New Observations Reveal Insights into the TOI-396 Three-Planet System An international team has studied a planetary system containing three exo planets orbiting the star TOI-396. This groundbreaking research,  published on November 22 on the  pre- print server arXiv, offers the first mass measurements for these  planets, enriching the understanding of the system's  pro perties. Overview of the TOI-396 Star System Star Pro perties and Location TOI-396 (HR 858 A), located about 103 light-years from Earth, is a bright star of s pectral ty pe F6 V. It has a size 26% larger and a mass 20% greater than the sun, an effective tem perature of 6,354 K, and an estimated ago of two billion years. It is  part of a binary system with a faint M dwarf com panion, HR 858 B. Exo planet Discovery via NASA's TESS In 2019, NASA's Transiting Exo planet Survey Satellite (TESS) identified three exo planets orbiting TOI-396, designated TOI-396 b, c, and d. Each of these  planets,...
