Behind the Paper posts on the dimpled surface of Pallas and LFC spectrograph calibration are our most viewed from February:
- Michael Marsset shares how advanced technology on the ESO's Very Large Telescope has for the first time revealed the precise size and shape of Pallas, including details of its surface which is so heavily cratered it looks like a giant golf ball.
- Searching for exoplanets requires precision; Bruno Leonardo Canto Martins describes how the installation of laser frequency combs (LFCs) to the High Accuracy Radial Velocity Planet Searcher (HARPS) provides the most precise calibration of astronomical spectra available.
