The discovery of quasars

https://www.astron-soc.in/bulletin/13March/001412013.pdf Bull. Astr. Soc. India (2013) 41, 1–17 The discovery of quasars K. I. Kellermann National Radio Astronomy Observatory, 520 Edgemont Road, Charlottesville, VA, 22901, US. A good historical perspective. I'd like to add a link to the article but not sure where. Hope an editor can do the necessary. — Preceding unsigned comment added by 115.135.199.33 (talk) 14:42, 21 May 2022 (UTC)[reply]

Quantity of Quasars

There are 2 different figures given for the number of detected quasars: 'more than a million' and 'more than 750,414'. Should one be changed to the other? 2A00:23C6:C14:301:483C:3AFF:B3:BF72 (talk) 18:50, 19 November 2023 (UTC)[reply]

They are two different estimates from two different sources, so it's unclear which is more correct. Perhaps this is a corollary to Segal's law? Praemonitus (talk) 05:48, 20 November 2023 (UTC)[reply]

Thanks for pointing that out. I've cleaned it up, so I hope it's clearer why one might have two different "numbers of known quasars". I've also left it as ranges, not specific numbers, since the latter changes pretty quickly as surveys are ongoing. - Parejkoj (talk) 19:27, 20 November 2023 (UTC)[reply]

Record for the most distant known quasar

Hi there, in the quasars article it says: "31.7 billion light-years away" but in the linked article about UHZ1 it says "UHZ1 is at a distance of 13.2 billion light-years" Could it be a Typo? Bye! 2A02:2454:8628:E300:DD04:6F54:9840:36F (talk) 06:06, 15 November 2024 (UTC)[reply]
