Bubbles blown by massive stars should contain shocked fast winds at temperatures ≥ 106 K that emit diffuse X-rays. Only two Wolf-Rayet bubbles have shown detectable diffuse X-rays - NGC6888 and S 308. We have obtained Chandra and XMM-Newton observations of these two bubbles to study their hot interior gas. We further use the results to suggest an explanation for the lack of detectable diffuse X-ray emission from other bubbles blown by massive stars.
