Born in Mexico City, he graduated from the National Autonomous University in Mexico City. In 1941 he worked in the Astrophysical Observatory of Tonantzintla, in 1944-1946 - in the United States: first, the observatory Keyzovskogo Institute of Technology (Cleveland), in 1945-1946 - in the observatories Yerkes and McDonald. In 1947-1972 he worked at the National Astronomical Observatory of the National Autonomous University (in 1948-1958, its director), he oversaw the creation of yet another observatory of the University in the mountains of San Pedro Martir. In 1950 - Director of the Astrophysical Observatory of Tonantzintla. He founded the National Institute of Astrophysics, Optics and Electronics Tonantzintla in 1972-1983 and was its first director. Since 1984- the Institute of Astronomy of the National Autonomous universiteta.Osnovnye works in the field of studies of different types of peculiar objects in our galaxy. Opened (1950-1952), regardless of X. J. Herbig, starlike objects characterized by strong emission lines in the spectra (Herbig - Haro).. According to modern concepts - are small clouds of gas moving through the interstellar medium at supersonic speeds, they can occur as a result of flare phenomena near the T Tauri stars. Discovered (1953-1954) flare activity (changes in brightness on the 0,5m-1,0m for 20-60 minutes) some stars in the Orion Nebula, and then in other stellar aggregates of different ages. This discovery marked the beginning of a broad study of flare stars in stellar associations and clusters. In 1952 as a result of the search of new objects with emission lines Haro discovered 67 new planetary nebulae (at that time they were aware of all 342). Developed (1955-1956) photographic method for the study of T Tauri stars with strong ultraviolet radiation. With this method, together with V. Leuthen studied at the Palomar 48-inch Schmidt telescope, a vast area near the south galactic pole, and discovered (1962) 8746 blue starlike objects to 19th magnitude. (Later, some of them have been identified with quasars.) Haro discovered and studied 44 galaxies with strong ultraviolet radiation. Investigated region of ionized hydrogen in galaxies M31, M33, M82 and M83. Opened 11 new in our galaxy, extragalactic a new one extragalactic supernova discovered one comet (Haro-Chavira 1954 k). His work defined the main directions of astronomical studies ongoing in Mexico.

Editor of "Bulletin observatories Tonantzintla and Takubayya" (1951-1974) and the "Bulletin of the Observatory of Tonantzintla" (1974).

Member of the Academy of Scientific Research (Mexico City) since its inception (1959), its president in 1960-1962, member of the National Bar (since 1954), member of the Colombian Academy of Exact, Physical and Natural Sciences (1970), vice-president of the International Astronomical Union ( 1961-1967).

Gold medal Luis G. Leon Mexico Astronomical Society (1953), National Science Award (1963), Gold Medal. MV Lomonosov Moscow State University, Academy of Sciences of the USSR (1985).
