Today we talk with Dr Christian Schwab, an astronomer at Macquarie University who has just helped develop one of the most precise tools ever built for detecting new planets outside our solar system. The NEID spectrometer was funded by NASA and the National Science Foundation, and has just started scanning the skies at the WIYN 3.5m telescope at Kitt Peak National Observatory in the US. This interview is hosted by Cosmos journalist Lauren Fuge.
