Moss spores withstand long term exposure outside space station
Tokyo, Japan (SPX) Nov 21, 2025 Researchers have demonstrated that moss sporophytes can withstand nine months of direct exposure to outer space and remain reproductively viable upon return to Earth. The study, published November 20 in the journal iScience, tested the durability of Physcomitrium patens spores affixed to the outside of the International Space Station. Lead author Tomomichi Fujita of Hokkaido University explained, "Most living organisms, including humans, cannot survive even briefly in the vacuum of space. However, ... read more |

Revealing Exoplanet Atmospheres with 3D Eclipse MappingLos Angeles CA (SPX) Oct 29, 2025 A team of astronomers co-led by Cornell University has produced the first three-dimensional map of an exoplanet's atmosphere, revealing WASP-18b's distinct temperature zones-including one region so ... more 
Multi-temperature coronal mass ejections shed light on solar system originsTokyo, Japan (SPX) Oct 28, 2025 Earth's atmosphere is periodically exposed to coronal mass ejections (CMEs)-large eruptions of solar plasma-but in the early solar system, these events were far more frequent and intense. Scientists ... more 
Newly found rocky super-Earth could become key focus in search for lifeLos Angeles CA (SPX) Oct 27, 2025 An international scientific team, including Penn State researchers, has identified a super-Earth exoplanet named GJ 251 c orbiting a nearby dwarf star less than 20 light-years away. The planet is es ... more 
Hydrothermal vents may have triggered early molecular chemistry on ancient EarthWashington DC (SPX) Oct 27, 2025 A study published in the Journal of the American Chemical Society recreated in the laboratory chemical reactions that may have occurred on Earth about 4 billion years ago, producing the first molecu ... more |

Ancient White Dwarf Reveals Ongoing Planetary Consumption
Los Angeles CA (SPX) Oct 24, 2025 A 3 billion-year-old white dwarf star, LSPM J0207+3331, located 145 light-years from Earth, has been found actively accreting material from the remains of its planetary system. This finding overturns assumptions about the evolution of stellar remnants and the long-term fate of planetary systems. Evidence for this ongoing consumption arises from the Keck Observatory's spectroscopic observations, which detected thirteen chemical elements in the star's atmosphere. These heavy elements likely originat ... read more 
Newly found super-Earth orbits nearby star in promising habitable zoneLos Angeles CA (SPX) Oct 24, 2025 Astronomers at the University of California, Irvine have discovered an exoplanet positioned in the habitable zone of its host star, where conditions may allow liquid water to exist on the surface. ... more |

Iron from deep-sea vents travels across oceans to fuel marine lifeBerlin, Germany (SPX) Oct 21, 2025 Most of the iron released by hydrothermal vents rapidly reacts with oxygen and sulfur, forming solid minerals that settle on the seafloor. Yet a small fraction defies this fate, remaining dissolved ... more 
Planet formation depends on when it happens: UNLV model shows whyLas Vegas NV (SPX) Oct 17, 2025 A new study led by UNLV scientists sheds light on how planets, including Earth, formed in our galaxy - and why the life and death of nearby stars are an important piece of the puzzle. In a pap ... more 
Stopping slime on Earth and in spaceTempe AZ (SPX) Oct 16, 2025 How do you prevent biofilms - large communities of bacteria like the slime on your teeth before you brush - from growing in water systems in space and on Earth? A multi-university research tea ... more 
Ancient Heavy Water Found in Planet-Forming Disk Reveals Solar Origins of Earth's OceansCharlottesville VA (SPX) Oct 16, 2025 Astronomers have detected "heavy water" in a planet-forming disk for the first time, uncovering compelling evidence that much of the water in our Solar System predates the Sun itself. The discovery ... more 
Geologists discover the first evidence of 4.5-billion-year-old "proto Earth"Boston MA (SPX) Oct 15, 2025 Scientists at MIT and elsewhere have discovered extremely rare remnants of "proto Earth," which formed about 4.5 billion years ago, before a colossal collision irreversibly altered the primitive pla ... more |
