In 1904, he went to Paris to find a job in astronomy with a recommendation from a Czech professor who was known in Paris. Initially, he had no money and no command of French, but he was nevertheless able to obtain a job at the famous
Paris-Meudon Observatory after its director,
Pierre Janssen, one of the cofounders of
astrophysics, saw Štefánik's talent. Štefánik owed to Janssen and
Camille Flammarion his social, political and
scientific career. The observatory was the most important centre for astronomy at the time so he gained massive prestige from his job. Between 20 June and 4 July 1905, Štefánik climbed
Mont Blanc (he did so several more times in the following years) to observe the Moon and
Mars. Then, he took part in an official French expedition to observe and record a full eclipse of the
Sun in
Alcossebre, Spain. He thus established his own reputation in French scientific society. He worked with
Gaston Millochau, a member of the
Académie Française, which made some of its members read his work. His studies and the results of his observations were published in reports to the Académie, and he received several awards for them. Later, he was invited to an international astronomer conference in
Oxford on solar research. Between 1906 and 1908, he was co-director of the Mont Blanc observatories company. In 1907, Štefánik received the
Prix Jules Janssen, the highest award of the
Société astronomique de France, the French astronomical society. . At the end of 1907, however, Janssen died and Štefánik lost his job. Since 1908, he had been charged by the French authorities with astronomical and
meteorological observations, (mainly observations of
solar eclipses) and political tasks in various countries all over the world, including (Algeria, Morocco,
Turkistan, Russia, India, the United States, Panama, Brazil, Ecuador, Australia, New Zealand,
Tahiti, Fiji, and Tonga). In Tahiti, he also built an observatory and a network of meteorological stations (rumour has it that much of his time in the Pacific Ocean was spent on spying on German positions). Between the trips, he regularly returned home to Košariská (the last time in 1913 for his father's funeral). In South America (especially in the
Galapagos Islands in Ecuador), he had an opportunity to show his diplomatic skills for the first time. In 1912, a mission from the Bureau des Longitudes, based in France, was led by Milan Rastislav Štefánik, with the assistance of Jaromír Králiček. Štefánik and Králiček arrived in Rio de Janeiro aboard the French steamship Amazone on 10 September 1912. Their equipment crates were promptly cleared by customs with the authorization of the Brazilian government. Štefánik brought with great consideration a set of equipment intended for the Brazilian National Observatory, which Morize had ordered from manufacturers in January 1912 to be used by the Brazilian team in the observation of the eclipse. This equipment included a Mailhat telescope with an impressive 8-meter focal length and a 15-centimeter aperture, coupled with a coelostat from the same manufacturer. The French team had the objectives of photographing the solar corona and conducting spectroscopic studies. They set up in a location near Passa Quatro (Minas Gerais), where they joined the main team of the National Observatory's expedition. In the city of Passa Quatro, there is a bust in honor of the astronomer Milan Rastislav Štefánik. What drew attention was that their equipment crates were immediately released by customs, thanks to the authorization of the Brazilian government. Milan Rastislav Štefánik showed great generosity by bringing a set of equipment intended for the Brazilian National Observatory to be used by the Brazilian team in observing the eclipse. This set included an impressive Mailhat telescope with an 8-meter focal length and a 15-centimeter aperture. Štefánik's presence and his equipment were valuable contributions to the advancement of science and astronomical research in Brazil at that time. Štefánik worked in
astrophysics and
solar physics, and became well known for his
spectral analysis of the Sun's
corona. He was involved in perfecting
spectrography and has been considered a predecessor of
Bernard Lyot. He also attempted to construct a machine for
colour photography and cinematography, and he had his design patented in 1911. ==Diplomacy==
