Fluidic Telescopes – We present a conceptual framework for optically designing space-assembled telescopes whose primary mirror is formed in situ via the enabling, scale-invariant technology of fluidic shaping. — astro-ph.IM

Mapped CBs (channel belts) outlined in black and the putative shorelines in blue. Yellow outlines indicate avulsed CB paths. The backwater/belt-width window for each CB is shown in orange. Avulsion

Constraints on broadcast and societal abundance compared for different broadcast luminosities in model set B at 1.4 GHz. Line styles and shading are the same as in Figure 7. —

Boundaries of the Habitable Zone. The horizontal axis marks the radiative flux relative to Earth and the vertical ones, the effective temperature and approximate spectral type of the host star

(a) Top panel shows independent of the temperature bias as a function of . Small orange triangles represent data from DM and small green triangles represent data from BB.

Degree of linear polarization as a function of phase angle measured in the R filter for 7 distant comets and for the interstellar Comet 3I/ATLAS (Z. Gray et al. 2025).

NASA’s Swift Ultraviolet/Optical Telescope (UVOT) observed interstellar comet 3I/ATLAS during two visits in July and August 2025. The panels show visible-light (left) and ultraviolet (right) images, where the faint glow
