What phenomenon does X-ray analysis reveal at the heart of NGC 2392?
Answer
A hot bubble of gas created by stellar wind collisions
Observations in high-energy wavelengths, such as those from the Chandra X-ray Observatory, show a hot bubble of gas at the center of the nebula. This is formed by the interaction of the central star's stellar wind—a stream of charged particles—colliding with the slower-moving gas that was ejected by the star in an earlier phase of its evolution.
