Operations CXO Status Report

Friday 28 January 2022 9.00am EST

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

Chandra press and image releases were issued on Jan 25 describing a new astronomical visualization of Eta Carinae, one of the most massive and eruptive stars in our galaxy. It is noted for a remarkable historical outburst, called the "Great Eruption," observed in the 1840s, which briefly made it one of the brightest stars in the night sky. It then faded over decades, owing to a small nebula of gas and dust, called the Homunculus Nebula, that was expelled during the blast and has blocked the light of the star. Now, using multiwavelength data from three of NASA's Great Observatories --- Chandra (X-rays), Hubble (visible and ultraviolet), and Spitzer (infrared) --- a digital model of the structures surrounding Eta Carinae has been constructed, allowing full visualization of the three-dimensional nebula from all directions. For details, see https://chandra.harvard.edu/press/22_releases/press_012522.html

The schedule of targets for the next week is shown below and includes observations of NGC5548 coordinated with HST.
