Teenage Planet System Shows How Starlight Turns Gas Giants into Rocky Worlds

A new computer study has shed light on why some planets in a young star system end up as barren rocks while others keep thick, fluffy atmospheres. Researchers led by Dr. Chen simulated the early years of a rare "teenage" planetary system—one that is still settling into its final shape. The simulation showed that intense radiation from the central star can strip away the light gases surrounding young planets, a process known as photoevaporation. As the gas is blown away, the planets lose mass, which in turn nudges them into slightly wider orbits over time. The model matched what astronomers actually see when they point telescopes at the real system: a mix of stripped‑down rocky worlds and still‑gassy planets, each spaced out in a predictable pattern. This suggests that the star’s harsh light plays a starring role in sculpting planetary families, gradually pushing lighter planets outward while leaving heavier, rockier ones behind. Understanding this natural “planetary makeover” helps scientists piece together the broader story of how solar systems evolve, from chaotic birth clouds to the orderly arrangements we observe today. The findings bring us one step closer to predicting the fate of worlds beyond our own, and they highlight the powerful influence of starlight on planetary destiny.

Hidden Solar Storms on the Sun’s Dark Side Confirm New Space‑Weather Forecasting Breakthrough

Scientists have just proved that a brand‑new method for predicting solar eruptions works even on the side of the Sun we can’t see from Earth. While developing their model, researchers had no idea that massive “superflares” were brewing on the Sun’s far side. When those hidden eruptions were finally spotted during the paper‑review process, they matched the patterns the team had forecasted almost perfectly. Dr. V. M. Velasco Herrera called the coincidence “pure luck, but also very revealing,” showing that the physics‑based approach can anticipate powerful X‑ray storms across the entire solar surface, not just the Earth‑facing half. The new system produces probabilistic, time‑and‑location forecasts for the most intense solar flares (S‑class, >X10). With advance warnings, power‑grid operators, satellite owners, and space agencies can take protective steps—adjusting satellite orbits, switching to backup systems, or delaying missions—to reduce damage from space weather. As Solar Cycle 25 ramps up, this breakthrough could dramatically improve our readiness for the next wave of extreme solar activity, safeguarding critical technology and infrastructure on the ground and in orbit.

Geothermal Power Poised for a Global Comeback

Geothermal energy is on the brink of a worldwide revival, says Ryan Law, CEO of Geothermal Engineering Ltd. As wind and solar farms become more common, their output still swings with the weather, leaving power grids in need of a steady, reliable source. Unlike nuclear plants, geothermal plants can be built faster, and they have a smaller environmental footprint than large dams. New drilling techniques borrowed from oil and gas—such as horizontal wells and high‑pressure water fracturing—are unlocking heat from deeper underground, making geothermal viable far beyond the traditional shallow hotspots. Stanford spin‑out Fervo Energy, for example, is constructing a 115‑megawatt plant in Nevada to power Google data centres, cutting well‑drilling time from two months to just 20 days with diamond‑tipped bits. Experts predict that “enhanced geothermal” could deliver electricity for under $80 per megawatt‑hour by 2027, cheap enough to compete with solar, wind, and natural‑gas power. A recent study suggests the United States could generate at least 90 GW of geothermal electricity by mid‑century—about 7 % of today’s total capacity. With tax credits still in place, the technology is moving from niche projects to a mainstream clean‑energy solution.
