Re: Halo not HALO
No idea where it will be pointed first, but, just like Hubble, I expect they will eventually try 'an empty piece of sky' and see what they find.
"In 1995, astronomer Bob Williams wanted to point the Hubble Space Telescope at a patch of sky filled with absolutely nothing remarkable. For 100 hours."
