- 1First direct radio signal detected from exoplanet●Reseachers detect a direct radio signal from planet beyond solar system for the first time
Researchers report the first direct radio signal detected from a planet outside the solar system, a milestone in the search for worlds beyond our own. The detection, picked up by astronomers studying distant planetary systems, could open a new way to study exoplanets' magnetic fields and potential habitability. Scientists caution that more observations are needed to confirm the signal's origin.
- 2Harvard Scientists Detect Radio Signal From Exoplanet●Harvard Scientists Detect Radio Signal Coming Directly From Planet Outside the Solar System
Researchers at Harvard report detecting a radio signal coming directly from a planet outside our solar system. If confirmed, it would mark a rare observation of radio emission from an exoplanet, potentially pointing to magnetic interactions between the planet and its star. Details on which planet is involved and how strong the signal is have not yet been released, and astronomers await independent verification of the finding.
- 3Earth microbes survive simulated conditions of Enceladus ocean▼Earth microbes survive simulated conditions of Saturn moon’s ocean
Scientists report that microbes from Earth can survive laboratory conditions designed to mimic the ocean beneath the icy surface of Saturn's moon Enceladus. The finding suggests life could persist in the moon's subsurface sea, strengthening the case that Enceladus is one of the most promising places in the solar system to search for extraterrestrial life. Researchers say future missions could test whether such life actually exists there.
- 4Philadelphia-area schools turn to solar power to cut utility costs▼Philadelphia-area schools are tapping the sun’s energy and saving money on utilities
School districts across the Philadelphia area are installing solar energy systems to reduce their utility bills. Districts see rooftop and ground-mounted panels as a way to redirect money from energy costs into classrooms while also cutting carbon emissions. The trend reflects a broader push by Pennsylvania schools toward renewable energy despite upfront installation costs.
- 5Kubota develops agrivoltaic system for rice farming under solar panels▼Kubota agrivoltaic system allows rice farming and combine harvesting beneath elevated solar panels
Kubota has introduced an agrivoltaic system that lets farmers grow and combine-harvest rice beneath elevated solar panels. The setup raises photovoltaic arrays high enough for standard farm machinery to pass underneath, allowing the same land to produce both food and renewable electricity. The idea is drawing attention as countries push to expand solar capacity without sacrificing farmland.
- 6Asteroid Bennu may have formed closer to the Sun●Asteroid Bennu may have formed much closer to the Sun than scientists thought
New findings suggest asteroid Bennu, a near-Earth object studied by NASA's OSIRIS-REx mission, may have originated much closer to the Sun than previously believed, challenging existing models of how the solar system's early materials were distributed. Scientists say the asteroid's composition could indicate it formed in a warmer region before migrating outward.
- 7Copper wire theft leaves Louisville interstates dark, city launches solar light pilot▼Copper wire theft leaves Louisville interstate stretches dark, prompts solar light pilot
Thieves have stripped copper wiring from Louisville's interstate lighting system, leaving long stretches of the highway dark at night and raising safety concerns for drivers. In response, local officials are launching a pilot program to install solar-powered lights that do not depend on copper wiring, aiming to deter future theft and restore illumination along affected corridors.

The Japanese word for the Sun is trending on Google in Japan, driven by news coverage of a study suggesting that early in its formation the Sun may have swallowed a giant Earth-sized planet. Posts share the Forbes Japan headline and discuss what this would mean for our understanding of the solar system's early history. The evidence is limited to this one headline, so wider reaction is not clear from the collected posts.
