Created the talk-page for the MACS J1149 Lensed Star 1 article - Enjoy! :) Drbogdan ( talk) 21:16, 2 April 2018 (UTC)
I think the star is not 9 billion light years away now. Rather, it was when the light reaching us now was emitted. The universe has expanded a lot since then and so its current distance is quite a bit greater. However, I don't know the current distance. — Preceding unsigned comment added by 66.96.194.172 ( talk) 02:00, 4 April 2018 (UTC)

I get 2.5121.5 ≈ 4.0, 2.51213.9 ≈ 360,000. WolfmanSF ( talk) 03:55, 5 April 2018 (UTC)
Hi, I noticed that the article name and the full title were not the same, should the page be moved to the more exact MACS J1149+2223 Lensed Star 1 to avoid confusion of the star cluster? User:SuperTurboChampionshipEdition 15:31, 5 April 2018 (UTC) [edit restore/add]
Done - BRIEF Followup re the main article => "restored original title name by the discoverers in the original Nature (journal) reference - please see the talk-page => Talk:MACS J1149 Lensed Star 1#Move title? - and - https://www.nature.com/articles/s41550-018-0430-3 " - hope this helps - iac - Enjoy! :) Drbogdan ( talk) 15:27, 6 April 2018 (UTC)

A brightness gain of 2000 equates to a magnitude change of -2.5 X log(10) (2000) =~ -2.5 X 3.3 =~ 8.3 . In the "Characteristics" section, the apparent magnitude increase given with the the "normally" addendum is only about 1.5 . — Preceding unsigned comment added by 58.166.227.224 ( talk) 06:11, 7 April 2018 (UTC)
Fascinating that it was visible in 2016 but not in 2011. Why is this? Has the status of the "star" been checked since? Has it been found since? Misty MH ( talk) 09:53, 8 April 2018 (UTC) Misty MH ( talk) 09:54, 8 April 2018 (UTC)
The article states "MACS J1149 Lensed Star 1, also known as Icarus, is a blue supergiant" but this source, used in the article, states "It also no longer exists". Would it therefore not be more correct to state "was a blue supergiant"? The source states that it collapsed into a black hole or wound up as a neutron star.

Can one tell which galaxy this star belongs to? S3rvus ( talk) 21:14, 29 March 2020 (UTC)
New record holder? Article probably needs updating: https://www.nasa.gov/feature/goddard/2022/record-broken-hubble-spots-farthest-star-ever-seen/ wotsuhthedeal ( talk) 15:38, 30 March 2022 (UTC)
I have not seen anywhere a statement about how long the microlensed brightening has lasted, or will last, or even whether it is still in effect. That appears to be the major constraint on how long we can observe Icarus, so it would be significant information. Zaslav ( talk) 21:02, 31 March 2022 (UTC)
