Carbon-rich hot bubble detected in the planetary nebula NGC 5189
Using ESA’s XMM-Newton space telescope, astronomers have found that the planetary nebula NGC 5189 harbors a carbon-enriched X-ray-emitting hot bubble. The discovery, presented in a paper published September 30 on arXiv.org, could shed more light on the nature of gaseous material in planetary nebulae.
