A new report claims the solar system's first planets were worlds of fire rather than ice, challenging the long-held picture of the earliest planetary bodies forming in cold, icy conditions far from the sun. The suggestion points to a hotter, more violent beginning for planet formation than scientists have typically assumed, and it is drawing attention from space enthusiasts and researchers questioning how the planets we know today first came together.

Analysis of solar-driven disasters is drawing attention to the risk that space weather poses to electricity grids and digital infrastructure. Strong solar flares and geomagnetic storms could damage transformers, knock out satellite communications, GPS and internet systems, with recovery potentially taking months. The discussion highlights how modern economies remain deeply exposed to events originating on the Sun and calls for better forecasting and grid hardening.

New research indicates Mercury is contracting more quickly than previously estimated. The smallest planet in the solar system has been cooling and shrinking for billions of years, causing its crust to buckle and form cliffs and ridges. The revised findings suggest this process is still active and accelerating relative to earlier models, prompting scientists to rethink how rocky planets cool over time.

Analysts say a Democratic sweep in the United States would benefit solar, energy storage systems (ESS) and power equipment companies. Shares tied to renewable energy and grid infrastructure are expected to gain as investors anticipate expanded clean energy spending and supportive policy under a Democratic-controlled government, drawing attention to related energy stocks.

Solar combined with battery storage is making its strongest case yet in Texas, according to energy industry reporting. The state's growing power demand and grid strain are driving interest in solar-plus-storage systems as a reliable alternative, and the argument is being closely watched by energy markets and policymakers elsewhere.

New research suggests icy moons can retain their subsurface oceans even after catastrophic impacts that break the moon apart. The finding implies that oceans on bodies like Europa or Enceladus could survive violent events, expanding the range of conditions under which habitable environments might persist in the outer solar system.

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.

Investors are watching whether a political 'blue wave' could boost renewable energy and power stocks. Commentary suggests solar, energy storage systems (ESS), and power equipment companies stand to gain if election outcomes shift policy toward stronger support for clean energy, grid investment, and related infrastructure spending.

A spacecraft built to explore icy moons where life could exist is flying close by Earth, using the planet's gravity to adjust its course. The maneuver is part of a long journey toward the outer solar system, where scientists hope to study oceans beneath the moons' surfaces. The flyby has drawn attention as a milestone in the search for conditions suitable for life beyond our planet.

Researchers have tested underwater solar panels at a depth of ten metres in the South China Sea, according to an industry report. The trial explores whether photovoltaic systems can generate usable power below the surface, where light is weaker but conditions are more stable. Details on efficiency results and which institution led the test have not been released, leaving the technology's practical prospects uncertain.

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.

A UK solar panel owner wanted panels specifically designed to perform under the country's frequent overcast winter skies. Off-grid users advised that rather than hunting for specialised cloudy-weather panels, the better approach is to oversize the system, since all panels lose output in low light and extra capacity compensates for seasonal shortfalls.
