Philip Plait's Bad Astronomy Newsletter covers recent astronomy and space science news, explaining phenomena such as novae, comets and galaxy collisions in an accessible way. Most of each issue is behind a Premium paywall, so the free excerpts show only the opening paragraphs.

A weekly-style space and physics newsletter that explains big science projects and ideas, such as the Thirty Meter Telescope's siting troubles, the IceCube neutrino observatory, and debates over Euclid's historical existence. Readers get accessible, narrative explanations of telescopes, particle physics and the history of science.
Planetocracy is a personal newsletter by a UK-based space commentator who argues for a new British space industrial policy aimed at colonisation, not just science missions. Issues mix policy advocacy, speculative essays on the Fermi paradox and monthly analysis of launch mass-to-orbit data for SpaceX and other providers.
