Luminous Stars
Objects in this class have 80 to 150 times the mass of the Sun and lifetimes of only a few million years. Unlike ordinary stars, they are strongly affected by the outward pressure of the light that they emit, which blows off massive winds from their outer atmospheres. Besides the Pistol Star, several other objects have been cited as the "most luminous star" in recent years. Almost all of them have been demoted by later, improved studies. Among the most famous is Eta Carinae, now confirmed to be a system of at least two stars. Our galaxy probably has 10 to 100 stars surpassing Eta Carinae, but their visible light is hidden by interstellar dust, hindering their immediate identification and detailed study. Most should eventually be observable in infrared light.

Famous quotes containing the words luminous and/or stars:
“Drawing is a struggle between nature and the artist, in which the better the artist understands the intentions of nature, the more easily he will triumph over it. For him it is not a question of copying, but of interpreting in a simpler and more luminous language.”
—Charles Baudelaire (1821–1867)
“the gray filth of it:
the knowledge that humankind,
delicate Man, whose flesh
responds to a caress, whose eyes
are flowers that perceive the stars ...”
