Title: An 800 million solar mass black hole in a significantly neutral universe at redshift 7.5Authors: E. Bañados, B.P. Venemans, C. Mazzucchelli, E.P. Farina, F. Walter, F. Wang, R. Decarli, D. Stern, X. Fan, F. Davies, J.F. Hennawi, R. Simcoe, M.L. Turner, H-W. Rix, J. Yang, D.D. Kelson, G. Rudie, J.M. WintersFirst Author’s Institution: The Observatories of the Carnegie Institution for ScienceStatus: Published in Nature, open access on arXivFigure 1.

Credit: Ana Frebel.With advances in technology and more time dedicated to deep sky surveys, we are able to probe deeper and deeper into the universe. Today’s astrobite is about a new discovery of the most distant quasar – an incredibly luminous active supermassive black hole – ever observed. It’s at a redshift z = 7.54: its light has been traveling towards us for 13.1 billion years, from when the universe was only 690 million years old.So why is this interesting? Surely as we look deeper, we’re bound to find more “most distant” objects – it’s just a matter of time. But finding objects like these is challenging, and such discoveries can reveal ...
