Part of the electromagnetic spectrum of an extremely luminous galaxy. This special type of galaxy -- a quasar -- is the most luminous object class in the Universe. The specific interval of its spectrum that is studied here traces the structure of diffuse gas in intergalactic space, along the quasar light's one-dimensional path to Earth. The intergalactic gas that the light passes through is primarily composed of neutrally-charged hydrogen, which creates a "forest" of absorptions in this specific interval of the quasar's spectrum.
