Spotted: Signature of Water in Microwave Laser Produced by Distant
Researchers were able to observe the distant galaxy through a trick called gravitational lensing, which was predicted in Albert Einstein's general theory of relativity. This effect refers to the way that light from a distant source is bent around a closer galaxy and is magnified; because the quasar's galaxy was so far away, researchers would never have been able to study it without this magnifying boost. Researchers are delighted with the work done to detect water in the ancient quasar galaxy, and say future high-powered telescopes, like the Square Kilometre Array, may be able to focus in on these water masers to learn more about how young galaxies behaved in the first few billion years after the Big Bang.
