Answer the following question: Information: - A light-year is a unit of length used to express astronomical distances. It is about 9 trillion kilometres or 6 trillion miles. As defined by the International Astronomical Union (IAU), a light-year is the distance that light travels in vacuum in one Julian year (365.25 days). Because it includes the word "year", the term light-year is sometimes misinterpreted as a unit of time. - Amazing Stories is an American science fiction magazine launched in April 1926 by Hugo Gernsback's Experimenter Publishing. It was the first magazine devoted solely to science fiction. Science fiction stories had made regular appearances in other magazines, including some published by Gernsback, but "Amazing" helped define and launch a new genre of pulp fiction. - A planetary system is a set of gravitationally bound non-stellar objects in orbit around a star or star system. Generally speaking, systems with one or more planets constitute a planetary system, although such systems may also consist of bodies such as dwarf planets, asteroids, natural satellites, meteoroids, comets, planetesimals and circumstellar disks. The Sun together with its planetary system, which includes Earth, is known as the Solar System. The term exoplanetary system is sometimes used in reference to other planetary systems. - The Skylark of Space by Edward E. '' Doc '' Smith was written between 1915 and 1921 while Smith was working on his doctorate . Though the original idea for the novel was Smith 's , he co-wrote the first part of the novel with Lee Hawkins Garby , the wife of his college classmate and later neighbor Carl Garby . The Skylark of Space is considered to be one of the earliest novels of interstellar travel and the first example of space opera . Originally serialized in 1928 in the magazine Amazing Stories , it was first published in book form in 1946 by the Buffalo Book Co. - Lee Hawkins Garby (18921953) was the co-author with Edward Elmer Smith of the 1928 serial novel "The Skylark of Space", the first science fiction story in which humans left the solar system. She was the wife of Dr. Carl DeWitt Garby, a friend of Dr. Smith's from college at the University of Idaho. - Hugo Gernsback (August 16, 1884 August 19, 1967), born Hugo Gernsbacher, was a Luxembourgish-American inventor, writer, editor, and magazine publisher, best known for publications including the first science fiction magazine. His contributions to the genre as publisher were so significant that, along with the novelists H. G. Wells and Jules Verne, he is sometimes called "The Father of Science Fiction". In his honour, annual awards presented at the World Science Fiction Convention are named the "Hugos". - Experimenter Publishing was an American media company founded by Hugo Gernsback in 1915. The first magazine was "The Electrical Experimenter" (19131931) and the most notable magazines were "Radio News" (19191985) and "Amazing Stories" (19262005). Their radio station, WRNY, began broadcasting experimental television in 1928. In early 1929 the company was forced into bankruptcy and the Gernsback brothers lost control of Experimenter Publishing. The magazines did not miss an issue and were quickly sold to another publisher. The Gernsbacks promptly started new magazines to compete with their former ones. - Interstellar travel is the term used for hypothetical piloted or unpiloted travel between stars or planetary systems. Interstellar travel will be much more difficult than interplanetary spaceflight; the distances between the planets in the Solar System are less than 30 astronomical units (AU)whereas the distances between stars are typically hundreds of thousands of AU, and usually expressed in light-years. Because of the vastness of those distances, interstellar travel would require a high percentage of the speed of light, huge travel time, lasting from decades to millennia or longer, or a combination of both. Given the information, choose the subject and object entities that have the relation of 'author'.
