The 25th Texas Symposium on Relativistic Astrophysics (TEXAS 2010) was held in Heidelberg, Germany, during December, 6-10, 2010. More than 350 astrophysicists attended a very interesting meeting, designed to exchange ideas and results, and to discuss future directions in Relativistic Astrophysics.

A wide range of scientific results were discussed in about 100 oral and about 200 poster contributions during nine parallel afternoon sessions and one highlight evening session. Further information, including the full program, can be found on the conference webpage: http://www.mpi-hd.mpg.de/texas2010/
