Abstract:
Recently there was a discovery of the most distant gamma-ray burst (GRB) ever recorded -in a galaxy at redshift 11, which means that we see it as it was only 400 million years after the Big Bang. The existence of such a distant GRB would have important consequences on our understanding of the conditions in which the first stars in the Universe formed and of the formation of the first galaxies. I will show that this signal was in fact Solar emission reflected off a space debris, the Breeze-M upper stage of a Russian Proton rocket. Unfortunately, such misidentifications will happen more often given that the number of satellites and space debris increases.
