New experiments reveal key process forming water during planet creation
Los Angeles CA (SPX) Oct 31, 2025 Our galaxy's most abundant type of planet could hold extensive liquid water reserves, scientists report, based on formative interactions between primitive atmospheres and magma oceans during early planetary evolution. Carnegie researchers Francesca Miozzi and Anat Shahar, along with an international team, published findings in Nature that illuminate water's role in shaping planetary habitability. More than 6,000 exoplanets have been identified in the Milky Way, with Sub-Neptunes the most common. T ... 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 |

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 
Rogue planet devours matter at record pace of six billion tonnes a secondParis, France (SPX) Oct 13, 2025 Astronomers using the European Southern Observatory's Very Large Telescope (ESO's VLT) have witnessed an extraordinary growth spurt in a free-floating planet, observing it accumulate mass at a rate ... more 
Completed Plato spacecraft construction enters final test campaignParis, France (SPX) Oct 10, 2025 By fitting its sunshield and solar panels, engineers have completed the construction of Plato, the European Space Agency's mission to discover Earth-like exoplanets. Plato is on track for the final ... more |

Rare clean room bacterium survives by playing dead UH team finds
Los Angeles CA (SPX) Oct 09, 2025 A University of Houston team reports that a rare bacterium found in NASA spacecraft assembly clean rooms can evade detection by entering dormancy, effectively "playing dead" in a nutrient-poor environment. The microorganism, Tersicoccus phoenicis, turned up in two clean rooms more than a decade ago in Florida and French Guiana. These facilities undergo rigorous sterilization to protect spacecraft and planetary bodies from contamination. Lead author Madhan Tirumalai and colleagues in UH's Dep ... read more
