When the sun sets, the world’s solar panels go dark. But above them, the night sky radiates a different kind of power. Every night, as the world cools, Earth dissipates much of its heat into space.

Scientists are learning how to turn the chill of outer space into a quiet source of electricity, using the night sky itself as a heat sink. By carefully managing how surfaces shed heat after dark, ...

A new 'cosmic veil' developed by engineers at the University of Surrey could help perovskite solar cells survive in space, opening a new gateway to lighter, cheaper and more efficient solar power for ...

NASA successfully conducted ground tests simulating the deployment of the Nancy Grace Roman Space Telescope's solar panels and sunshade, verifying their functionality in preparation for launch. The ...

Space-based solar panels could enable solar power to be harvested continuously instead of only when sunlight reaches Earth, reducing Europe’s need for Earth-based wind and solar by 80%, finds a study ...

Troublesome lunar dust could soon be transformed into solar cells to help power moon bases and humanity's push to explore further out into space. This is the promise of an international team of ...
