Roy published Shukra Bhraman (Travels to Venus) in 1879, though it had been written 22 years earlier in 1857. This story is of particular interest to literary historians, as it described an interstellar journey to another planet and its description of the alien creatures that are seen in Uranus. The work used an evolutionary theory similar to the origins of man: "They resembled our apes to a large extent. Their bodies were covered with dense black fur. Their heads were larger in comparison with their bodies, limbs sported long nails and they were completely naked." This story was published a decade before H. G. Wells’ The War of the Worlds (1889) in which Wells describes the aliens from Mars.
