Exploring Cassiopeia A: The 17th Century Supernova Remnant

[Nugatory]

From the Washington Post's coverage of the IXPE orbiting telescope:

Cassiopeia A is the remnant of a supernova explosion that took place when a gigantic star collapsed in the 17th century. It's visible in the night sky about 11,000 light-years away

Mixing the time of observation with the actual time of event?

Come on, starting a rant for every illogical absurdity picked from the news would earn me a permanent ban within a day, I guess Don't take this so seriously
