Using the remarkable Multi Unit Spectroscopic Explorer (MUSE) instrument
on ESO’s Very Large Telescope (VLT) at the Paranal Observatory in Chile,
astronomers have discovered and imaged an Enormous Lyman-Alpha
nebula (ELAN) around the quasar 4C.10.29 ( aka SDSS J102009.99+104002.7)
at a redshift of z = 3.164.
That large a redshift implies the object is now being seen about 2 billion
years after the big bang.

A paper has been submitted by Fabrizio Arrigoni Battaia et.al entitled
"Inspiraling Halo Accretion Mapped in Lyman-α Emission around a z∼3 Quasar" .
The paper is available for download from here :-

MUSE - the Multi Unit Spectroscopic Explorer - is one of the most sophisticated
instruments ever attached to a telescope. An image of it appears below (copyright ESO).
A link to a 33 minute documentary on the creation of MUSE can be found in the IceInspace Astronomy Books and Media forum here :-
