- 1Solar and wind hit record 80% of Australia's power demand●"Solar and wind generation meet record 80% of power demand on Australia’s national grid" # Australia # Energy # Renewabl
Renewable sources supplied a record 80% of electricity demand on Australia's national grid, with solar and wind generation combining to reach the milestone. The result is being cited as evidence that renewables can carry a large share of a major advanced economy's power system, adding to ongoing debate in Australia about the pace of the energy transition and the future role of coal and gas.
- 2ESA's JUICE spacecraft sweeps low over the Indian Ocean●Heads up (especially if you’re currently on a ship in the Indian Ocean). ESA’s JUICE mission to Jupiter & its icy moons
ESA's JUICE mission to Jupiter and its icy moons is performing its second Earth gravity assist, passing less than 10,000 km overhead at 13:45 CEST, directly above the Indian Ocean. The flyby uses Earth's gravity to adjust the spacecraft's trajectory toward Jupiter. A final Earth slingshot is planned for 2029 before JUICE continues to the outer solar system.
- 3Keck Observatory data reveals youngest exoplanet yet▼Data from Hawaiʻi’s W. M. Keck Observatory reveals youngest planet outside solar system
Data gathered at Hawaiʻi's W. M. Keck Observatory has led to the identification of what researchers describe as the youngest planet found outside our solar system. The discovery, reported from the observatory atop Maunakea, offers scientists a rare chance to study a planet in the earliest stages of its formation, and is drawing attention for Hawaiʻi's role in the finding.

New research reported by Science News suggests that magnetic fields may have played a key role in the formation of the solar system, potentially helping to trigger the collapse of the gas cloud that ultimately formed the sun and planets. The finding adds to debate over what set off the processes that shaped our cosmic neighbourhood billions of years ago.
- 5Study finds utility-scale solar lowers grid costs▼Our study didn’t ignore grid costs. We measured them — and utility-scale solar lowers them.
Researchers have pushed back against claims that their work overlooked grid expenses, saying the analysis directly measured them and found that large-scale solar power reduces overall system costs. The findings, published via Commonwealth Beacon, argue utility-scale solar delivers savings for electricity customers rather than added burdens, in a contribution to ongoing debates over renewable energy economics.
- 6New Findings on Enceladus Boost Search for Life●Great News from Saturn’s Moon Enceladus in the Search for Life in Space | Newswise
Researchers are reporting encouraging developments from Enceladus, Saturn's icy moon, in the ongoing search for life beyond Earth. The moon is considered one of the most promising places in the solar system to look for life, thanks to the global ocean beneath its icy crust that sends plumes of water vapor into space. The latest results add to growing scientific interest in missions that could directly sample that subsurface ocean for signs of life.
- 7Solar System's First Planets May Have Formed From Fire, Not Ice▼The Solar System’s First Planets Were Made of Fire, Not Ice
A new report from Universe Today claims the Solar System's earliest planets formed in fiery, hot conditions near the young Sun rather than in the cold outer regions long assumed. The idea challenges the standard picture of planet formation, in which rocky worlds built up close to the Sun while icy bodies accumulated farther out. Astronomers and space enthusiasts are weighing what this would mean for theories of how Earth and its neighbours came together.
- 8Pittsburgh green advocates launch solar panel group buy▼Green advocates organize group buy of solar panels for Pittsburghers to save on energy bills
Green advocates in Pittsburgh have organized a group purchasing program for solar panels, allowing residents to buy systems together at a discounted rate to cut their energy bills. The initiative aims to make renewable energy more affordable for households across the city by pooling demand to negotiate lower installation prices.
- 9Solar Projects Too Complex for Standard Solutions●Solar projects are becoming too complex for standard solutions
Trade coverage in the solar sector argues that photovoltaic projects have outgrown off-the-shelf engineering approaches. Growing project scale, varied grid requirements, and site-specific conditions are making one-size-fits-all designs harder to apply, pushing developers and equipment makers toward more customised planning, equipment and system integration as the industry matures.
