Wen-Fan Feng et al 2026 ApJL 1003 L35
According to calculations, in a 4-year period researchers may detect of order one compact binary system in which the binary’s inspiral and the spin of its neutron star component both produce gravitational waves.

Postperihelion Optical Low-Resolution Spectroscopy of Interstellar Comet 3I/ATLAS

Hideyo Kawakita et al 2026 ApJL 1000 L60
Spectra of 3I/ATLAS as it retreated from its encounter with the Sun show that the comet’s mixing ratios of CN, C3, and C2 with respect to water are similar to those of solar system comets, while NH2 is depleted.
