During the last week Chandra completed the observing schedule as planned.

Chandra passed through the fifteenth and sixteenth eclipses of the season on Dec 05 and Dec 08 respectively, with nominal power and thermal performance.

A Chandra image release was issued on Dec 6 describing Chandra observations of planetary nebulae. Data from Chandra reveal winds being driven away from the central white dwarfs so quickly that they create shock waves during collisions with slower-moving material previously ejected by the star. The gallery contains a half a dozen planetary nebulas that have been observed both by Chandra and NASA’s Hubble Space Telescope. For more details see: https://chandra.harvard.edu/photo/2021/pne/

A Chandra press release was issued on Dec 9 describing a mini-jet found near the Milky Way's supermassive black hole. The release describes a follow up to the 2013 Chandra discovery of a southern jet from the central black hole. The new data have allowed astronomers to infer the existence of a northern jet and conclude the central black hole surged in luminosity at least a millionfold in the last million years.

The schedule of targets for the next week is shown below and includes an observation of QSOJ1131-123 coordinated with XMM-Newton.
