A key issue of the star formation process is its independence from the environmental conditions. In particular, it is not clear whether star formation in the outer Galaxy occurs in the same way as in the inner Galaxy. We present preliminary results of the analysis of a ∼440 Ks ACIS‐Chandra observation of NGC1893, a young cluster (∼3–4 Myrs), far away from the Galactic Center with the aim to study star formation in the outer region of the Galaxy and investigate the coronal properties of the cluster stars. We detect more than 1000 X‐ray sources, most of which are likely cluster members. We present also a preliminary analysis of X‐ray variability of the cluster stars.
