Time-consuming observations with existing large telescopes have shown that the spectra of quasistellar objects are exceedingly complex. A VLT is needed to obtain the highest spectral resolution and to study in detail the numerous absorption lines. Drs. Jean-Pierre Swings (Institut d'Astrophysique in Liege, Belgium) and Jean Surdej (ESO) would like to use their nights to investigate the nature ofsome of the most distant objects in the universe
