- 1Real-time Solar System map tracks 526k asteroids liveโShow HN: Real-time Solar System with 526k asteroids and all tracked satellites
A new interactive tool renders the Solar System in real time, plotting roughly 526,000 asteroids along with all tracked satellites. The project was shared on Hacker News, where it drew strong engagement and discussion about the data sources, rendering performance, and visualisation approach used to display the asteroid belt and orbital paths.

Peter Watts' 2006 hard science fiction novel Blindsight is back in discussion among readers. The book, which follows a crew sent to investigate an alien presence at the edge of the solar system, is widely regarded as one of the most intellectually demanding first-contact stories, exploring consciousness and the possibility that intelligence can exist without self-awareness.
- 3Triton And Callisto Go On A Date In New Animated EpisodeโTriton And Callisto Go On A Date - Part 1
The first part of a new episode titled 'Triton And Callisto Go On A Date' is drawing heavy attention, with hundreds of thousands of likes already. The installment comes from SolarBalls, an animated series that turns moons and planets of the solar system into characters, imagining Neptune's moon Triton and Jupiter's moon Callisto meeting up romantically.

A widely viewed commentary argues solar power is now outperforming what is often billed as nuclear energy's strongest advantage โ its reliable, always-on baseline output. The discussion centers on plummeting solar costs, cheaper storage, and how paired solar-and-battery systems increasingly compete with nuclear plants on both price and dependability, feeding an ongoing debate about which technology should anchor the world's clean energy transition.

California has legalized plug-in solar panels for homes and apartments, allowing residents to use portable, balcony-style solar units without complex permitting or professional installation. The move opens access to solar power for renters and apartment dwellers who previously could not install rooftop systems. Supporters view it as a step toward cheaper, cleaner energy and broader participation in the state's transition away from fossil fuels.

A new study concludes the solar system is inherently unstable and will eventually be completely destroyed, with planetary orbits chaotic over long timescales. The finding is drawing wide attention online, with readers discussing how delicate the apparent stability of the planets is and what the research says about the system's long-term fate.
- 8Astronomers Link Chemical Clocks to Planet-Hosting Solar AnalogsโPlanets Around Solar Twins/Analogs (PASTA) III: Chemical Clock Relations in Planet-Hosting Solar Analogs
A new study from the PASTA project examines planets around solar twins and analogs, using chemical clock relations to estimate stellar ages in systems that host planets. By comparing chemical composition and age indicators in Sun-like stars, researchers aim to better understand how planet formation relates to stellar evolution. The paper is the third in the PASTA survey series.
- 9Virtus Solis Signs 20-Year Space-Based Solar Power DealโVirtus Solis Signs 20-Year Space-Based Solar PPA With Brae Systems for Up to 250 MW
Space-based solar startup Virtus Solis has signed a 20-year power purchase agreement with Brae Systems for up to 250 megawatts of orbital solar energy. The deal represents a landmark commercial commitment to space-based solar power, a technology long considered speculative. If delivered, it would make Virtus Solis one of the first companies to sell electricity collected in space to customers on Earth under a long-term contract.

Pensioners under the Philippines' Government Service Insurance System are set to receive larger benefits, coinciding with the launch of a solar loan program on September 30. The GSIS initiative pairs improved retirement payouts with financing aimed at making rooftop solar more accessible, part of a wider push toward renewable energy in the country. Details on eligibility and loan terms have not yet been fully outlined.
