Reflect Orbital's plan to launch thousands of sun-reflecting satellites has drawn sharp criticism from astronomers. A figure of 50,000 mirrors by 2035 was cited as 'catastrophic for astronomy' by scientist Luca Benvenuti, as the company seeks US regulatory approval from the FCC. Researchers worry the mirrors' bright glare would interfere with telescopes and darken the night sky for ground-based observations worldwide.

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.
- 3Solar Storms Seen as Growing Threat to Power GridsβDisasters from the Sun: Threats to Power-grids and Digital Infrastructure
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.
- 4Scientists Say Sun and Moon Tides May Trigger EarthquakesβThe Sun And Moon Can Trigger Earthquakes, And Scientists May Finally Know How
New research suggests the gravitational pull of the Sun and Moon, which drives tides in the Earth's crust, may help trigger earthquakes. Scientists believe they have identified the mechanism by which these small tidal stresses can nudge faults already close to slipping, potentially explaining why some quakes occur at particular tidal phases.

OxfordAQA, the exam board partnership between Oxford University Press and AQA, has trained more than 100 teachers in Bangladesh, according to the Daily Sun. The training supports teachers delivering OxfordAQA's international GCSE and A-level qualifications, which are used by schools in Bangladesh and worldwide, as the board expands its footprint in South Asia's growing international education market.
