Declination
Surely the lines of ascension are great circles (not small circles), and there are 24 of them, which means they are 1 hour apart?

Attempted to tidy up the "Future" section, recently added in a rather scrappy edit. I've deleted the rather clumsy nicknames of Milkomeda and Milkdromeda.

SN 2023ixf
Dropped the name "Big Dipper" from the Constellation field because Ursa Major is the constellation, while the Big Dipper is an asterism; changed the name of the galaxy of the 2014 supernova from "Cigar Galaxy (M82)" to "M82 (Cigar Galaxy)" to give more prominence to a formal name which matches the name of the Wikipedia article

Quasi-star
Created a link to the supermassive black hole in the Galactic Center; changed "center of our galaxy" to "center of the Galaxy" to use a capital G in Galaxy.

SN 2023ixf
Added a clarification that the progenitor's estimated absolute magnitude is in the near-infrared. This complicates interpreting how bright it would appear at a distance of 10pc. The reference at The Astronomer's Telegram does not specify whether this is on the "Vega" system or is an AB magnitude. Giving an estimate of the visual magnitude would require using a colour index. Those estimates have therefore been deleted.
