Heaviest Known Star Observed from Space

An American Astronomical Society Meeting Release

June 13, 1995: Observations with the Hopkins Ultraviolet Telescope (HUT) of the most massive star currently known have revealed new features of its hot outer layers, which are being blown away from the star at speeds of up to 2300 miles per second due to its extreme luminous energy output. These features in turn provide information about physical characteristics of the star, such as its temperature, luminosity, chemical composition, age, and mass, or the total amount of matter it contains.
