GRB 070125

GRB 070125 is a gamma ray burst that occurred on 2007 January 25. It is unique in that it did not occur in a galaxy, but in intergalactic space. This is unusual, since GRBs are caused by hypernovae of young massive stars, which usually means having to reside in a galaxy, as almost all stars are formed in galaxies, particularly high mass ones.

It is theorized that the star formed in the tidal tail resulting from the interaction of two nearby galaxies, deep in intergalactic space.
