Popis (v anglickém jazyce):

Observations of the Gamma-Ray Burst GRB 050904 in different filters in the visible (z- and I-band) and near-infrared (J-, H-, and K-band). The observations were done with FORS2 and ISAAC on the 8.2m Antu (UT1) telescope, which is part of ESO's VLT at Paranal. The burst is seen in the lower middle. It is obvious that the GRB is much fainter in the I-band and becomes more and more brighter as the wavelength increases. This indicates the object is at a high redshift, hence, is very far away.
