Planetary reflectivity (top; total flux) and polarization (bottom; polarized flux) as a function of scattering angle (or phase angle) and wavelength (colors). Glories, rainbows, Rayleigh scattering, and ocean glint generate
Combined white light image of 3I/ATLAS, created by median stacking white light images produced by collapsing in wavelength individual data cubes. The field of view displayed is 40″ × 40″.
We may already be broadcasting signals to the universe and alien life that inadvertently scream “we’re here, come find us!” — and any potential intelligent life in the universe could
