Hello, I'm Arccosecant. I noticed that you recently removed content from Chandra X-ray Observatory without adequately explaining why. In the future, it would be helpful to others if you described your changes to Wikipedia with an accurate edit summary. If this was a mistake, don't worry; the removed content has been restored. If you would like to experiment, please use your sandbox. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. — csc^-1 19:35, 11 April 2021 (UTC)
