We explore the possibility of probing (ultra)- light dark matter (DM) using \Moss spectroscopy technique. Due to the time-oscillating DM background, a small shift in the emitted photon energy is produced, which in turn can be tested by the absorption spectrum. As the DM induced effect (signal) depends on the distance between the Mossbauer emitter and the absorber, this new proposal allows to probe DM mass inverse of the order of the macroscopic distance scales. By using the existing synchrotron based Mossbauer setup, we can probe DM parameter space which is at par with the bounds from various fifth force experiments. We show our method can improve the existing limits coming from experiments looking for oscillating nature of DM, by several orders of magnitude. On top of that, an advancement of the synchrotron facilities would enable us to probe the uncharted territory by several orders of magnitude, and in principle may enable us to look for DM in a new way.
