- 1First direct radio signal detected from planet beyond solar system▼Reseachers detect a direct radio signal from planet beyond solar system for the first time
Researchers have reported detecting a direct radio signal from a planet outside the solar system for the first time. The announcement is being widely shared as a potential milestone in the study of exoplanets, since radio emissions have previously been observed mainly from stars and other cosmic objects rather than from planets themselves. Details about which planet was involved and how the signal was confirmed have not yet been widely reported.
- 2Mercury Is Shrinking Faster Than Scientists Expected●Mercury is shrinking faster than anyone thought
New research indicates Mercury is contracting more quickly than previous estimates suggested. The smallest planet in the solar system has been cooling and shrinking for billions of years, causing its crust to wrinkle and fault. The updated findings are drawing attention from scientists and space enthusiasts, prompting discussion about what the faster contraction reveals about the planet's interior and its ongoing geological evolution.
- 3First radio waves detected from an exoplanet hint at alien auroras●First radio waves seen from an exoplanet hint at otherworldly auroras # science # astronomy https://www. sciencenews.org
Astronomers have picked up radio waves from an exoplanet for the first time, a signal that could indicate auroras similar to those seen on Earth and the solar system's giant planets. The detection opens a new way to study magnetic fields and atmospheres of planets orbiting other stars, and scientists say future observations could reveal more about potentially habitable worlds far beyond our solar system.

Researchers have successfully generated solar power from panels placed 10 metres below the sea surface, according to a Euronews report. The experiment suggests underwater photovoltaic systems could one day complement offshore wind and floating solar farms, though questions remain about efficiency losses, maintenance costs and marine impact. The findings have drawn interest as countries look for new ways to expand renewable energy capacity.
- 5Harvard Team Detects Radio Signal From Exoplanet▼Harvard Scientists Detect Radio Signal Coming Directly From Planet Outside the Solar System
Harvard scientists report detecting a radio signal apparently coming directly from a planet outside the solar system. If confirmed, it would be a rare example of a radio emission traced to an exoplanet, possibly generated by the planet's magnetic field interacting with its star. Astronomers say such detections could open a new way to study distant planets, though further observations are needed to verify the signal's origin.
- 6Solar Storms Pose Growing Threat to Power Grids●Disasters from the Sun: Threats to Power-grids and Digital Infrastructure
An analysis published by the Observer Research Foundation examines how solar activity can trigger disasters on Earth, warning that solar storms threaten power grids and digital infrastructure. The piece highlights the vulnerability of modern electricity networks and communications systems to severe space weather events, and the potential scale of disruption if a major storm were to hit.
- 7Icy moons may keep hidden oceans even after collisions●Icy moons may hold on to their underground oceans even after being smashed apart
New research suggests icy moons in the outer solar system could retain their subsurface oceans even if they are shattered by large impacts, with fragments potentially holding on to liquid water. The finding has implications for the search for life, as it widens the range of places where habitable conditions might survive dramatic collisions and reassembling events over billions of years.
- 8Kubota unveils agrivoltaic system combining rice farming with solar power▼Kubota agrivoltaic system allows rice farming and combine harvesting beneath elevated solar panels
Kubota has introduced an agrivoltaic system that lets farmers grow rice and harvest it with standard combines beneath elevated solar panels. The setup raises photovoltaic arrays high enough for machinery to work underneath, letting the same land produce both food and electricity. Coverage in energy media is highlighting it as a practical answer to land-use conflicts between agriculture and renewable energy expansion.

CGTN's RAZOR programme explores whether solar technology can play a role in protecting global water supplies. The report examines how solar power could be used to address water scarcity, from powering desalination plants to pumping and purification systems. As droughts and water shortages intensify worldwide, the intersection of renewable energy and water security is drawing renewed attention from researchers and policymakers.
- 10Asteroid 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.
- 11SunCulture Secures $10 Million to Expand Solar Irrigation in Africa▼SunCulture Secures USD 10 M Financing To Expand Solar Irrigation In Africa
SunCulture, a company providing solar-powered irrigation systems for smallholder farmers, has secured USD 10 million in new financing to scale its operations across Africa. The funding will support expansion of its solar irrigation solutions, which help farmers boost yields while cutting reliance on rain-fed agriculture and costly diesel pumps. The deal highlights growing investor interest in African climate-focused agritech startups.
- 12Philadelphia-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 in the Philadelphia area are installing solar energy systems to reduce their utility bills. District officials say the move to solar power is delivering meaningful savings on energy costs, which can be redirected toward educational priorities. The shift reflects a broader trend of Pennsylvania schools adopting renewable energy as a way to manage tight budgets while cutting emissions.
- 13Copper 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.
