Neutron stars glow due to their high temperature, but what will they look like in the far future once they cool sufficiently to no longer emit visible light? This has been a difficult question for me because they consist of degenerate neutron matter. Would they strongly absorb visible light and appear black? Would they be reflective and metallic instead? Or would they be transparent?
