First Detection of Reflected Visible Light from 51 Pegasi b
22 April 2015: Astronomers using the HARPS planet-hunting machine at ESO’s La Silla Observatory in Chile have made the first-ever spectroscopic detection of visible light reflected off an exoplanet. These observations also revealed new properties of this famous object, the first exoplanet ever discovered around a normal star: 51 Pegasi b. The result promises an exciting future for this technique, particularly with the advent of next generation instruments, such as ESPRESSO, on the VLT, and future telescopes, such as the E-ELT.
