Detecting Extra-solar Planets Now Easier With New ESO Imaging Spectrograph |
Observing the image of a faint object that lies close to a star is a demanding task as the object is generally hidden in the glare of the star. Characterising this object, by taking spectra, is an even harder challenge. Still, thanks to ingenious scientists and a new ESO imaging spectrograph, this is now feasible, paving the way to many new thrilling discoveries. |
