Talk:MACS0647-JD

Comments

where is the location of this galaxy? At least I think it could be said it is located between Ursa Minor and Ursa Major, somewhere near Polaris.

what is CLASH, resp why is it not linked? The Cluster Lensing And Supernova Survey with Hubble (CLASH),an international group led by Marc Postman of the Space Telescope Science Institute in Baltimore, Md. (okay, just now someone seems to have added it).

why is there no link or even a second picture with the inset of this galaxy into the surrounding stars/galaxies, as it can be found on NASA website and on many other, eg here http://cdn4.spiegel.de/images/image-426393-galleryV9-vejl.jpg or at least here: http://www.nasa.gov/images/content/706977main_distance-record-670.jpg . This would explain a little more than only a 5-or-so pixel image with a bright dot shown here.

And it could only be seen with the help of the mass of the massive galaxy cluster MACS J0647+7015.

A link to http://hubblesite.org/newscenter/archive/releases/2012/36 , the official Hubble page, is missing and maybe better than links to other "space telescope" sites?

Isn't this superseeded by GN-z11 or is it the same galaxy? https://en.wikipedia.org/wiki/GN-z11 — Preceding unsigned comment added by 91.41.252.15 (talk) 11:13, 1 August 2020 (UTC)[reply]

Photometric vs. spectroscopic redshifts

Many articles on similar have not distinguished between photometric and spectroscopic redshifts (the latter being generally both more reliable and more precise). I have now made this clear for this page. — Preceding unsigned comment added by 31.205.108.227 (talk) 16:43, 16 July 2014 (UTC)[reply]
