  Jets and direct photons are used to probe the formation and the properties of
the Quark-Gluon Plasma (QGP) by the ALICE Collaboration. The results shown here
will present the measurements obtained from Pb$-$Pb and p$-$Pb collisions. It
is observed that in Pb$-$Pb collisions jets are collimated and hadron yields
($\pi^{0}$ and $\eta$) at high transverse momentum undergo strong suppression
due to the interaction of the patrons with the QGP. On the other hand, photons
do not show any suppression in this region, and, in addition, an excess
attributed to a thermal emission is observed at low transverse momentum. No
hints of medium modifications are observed for the p$-$Pb results, for which a
jet quenching limit of $-$0.4 GeV/$c$ is calculated.
