  NOvA is a long-baseline neutrino experiment that uses an upgraded NuMI
neutrino source at Fermilab and a 14-kton detector at Ash River, Minnesota. The
detector has a highly active, finely segmented design that offers superb event
identification capability. This talk presents the latest $\nu_\mu$
($\bar{\nu}_\mu$) disappearance and $\nu_e$ ($\bar{\nu}_e$) appearance combined
results using the first NOvA anti-neutrino beam data. In the far detector, 18
$\bar{\nu}_e$ candidate events are observed, with a significance of
$\bar{\nu}_e$ appearance more than 4 $\sigma$. The NOvA results favor a normal
neutrino mass hierarchy.
