One detail I really appreciated in Hail Mary (and is also not a major spoiler) is that, when they are looking at data of brightness from nearby stars, they say they compiled it predominently from amateur astronomers, some of whom have thousands of dollars of expensive equipment. As someone who has done a lot of variable star astronomy, this is 100% correct. There are some super dedicated people out there who track star luminosity on their own time with their own equipment and they deserve so much credit for that!!!!
