The state-of-the-art NEID spectrometer at the WIYN Observatory is fully operational thanks to a team of scientists including Prof. Cullen Blake, Associate Professor. NEID is a powerful new tool that will help "detect and discover new exoplanets." The precision of NEID is of particular note. Speaking with Penn Today, Prof. Blake explained that "for a long time, the state-of-the-art was about 1 meter per second, so about 10 times worse than the signal from Earth orbiting the Sun. Now, with NEID, that resolution is about 20-30 cm per second."
