Barbara J. Becker (Cambridge Univ. Press, 2017) In this exhaustive biography, Barbara Becker celebrates British astronomers William and Margaret Huggins. William contributed to the origins of astrophysics as the first to use a spectroscope to detect stellar motion in the line of sight; Margaret pioneered astrophotography. Black Hole Blues Janna Levin (Alfred Knopf, 2017) Astrophysicist Janna Levin records the long, arduous journey of the scientists building the nascent field of gravitational waves, from the enthusiasm of its founders to first detection five decades later (see Sheila Rowan’s review: Nature 532, 28–29; 2016).
