How astronomers measure distances in space, from parallax to redshift
Astronomers chain parallax, stars of known brightness and redshift to span the universe, and the expansion rate they give disagrees with a second method.
Two studies say the LISA observatory could detect planets orbiting pairs of white dwarfs
Papers published November 10 describe how a planet would mark the gravitational waves from paired white dwarfs, and how Webb could confirm it.
