In an attempt to clarify the characteristics of R136a1, astronomers decided to use the Zorro receiver mounted on the 8.1-meter Gemini South telescope in Chile. Photo of the most massive star in the Universe In recent years, many telescopes (including the famous Hubble) have made a number of observations of R136a1, but none of them get sufficiently clear images to consider all its neighbors. The situation is further complicated by the surrounding gas and dust clouds. The radiation of its neighbors is superimposed on the light emitted by R136a1, significantly complicating the assessment of its brilliance. It is located in the center of a star cluster. As for the mass, astronomers estimated it at 250 – 320 masses of our Sun.Īt the same time, the study of the giant luminary was fraught with a number of difficulties. The first measurements have already shown that the star has a record luminosity that is millions of times higher than the solar one. R136a1 can rightfully be called the pearl of the Tarantula Nebula. It became the first supernova observed in the Earth’s sky with the naked eye in the last 300-plus years. In 1987, a supernova SN 1987A broke out on the outskirts of the Nebula. It is home to some of the brightest and most massive luminaries known to science. The Tarantula nebula is a giant cloud of ionized hydrogen, which length exceeds a thousand light-years. This is a region of active star formation located in the Large Magellanic Cloud, a moon galaxy of our Milky Way. The star R136a1 is located in the Tarantula Nebula. To date, it ranks first in the list of the most massive stars in the Universe. The staff of the Gemini Observatory published the most detailed image of the blue supergiant R136a1.
